IO

The work of the IO research axis aims to propose a tool-based approach to supporting collaboration between organizations.

Context of the research

The work of the IO research axis aims to propose a tool-based approach to supporting collaboration between organizations. The concept of cooperation can be broken down into three separate objectives which make up the three levels of our approach:

  • Defining the collaboration: This primarily involves defining how the activities that needs to be carried out by the collaborating partners to meet their collective goals are partitioned (assignment and sequencing). This first level aims to offer tools that are both theoretical (concepts and methods) and practical (software prototypes), which allow (i) the formal characterization of a collaborative situation (collection of information about the partners, the collaborative objectives, the collaboration context, etc., in the form of models) and (ii) automated or assisted exploitation of the acquired knowledge to make automatic deductions or proposals, to evaluate and validate collective behavior models (in the form of collaborative process mapping), related performance indicators and other models that are relevant to the target collaboration (mapping of risks associated with the cooperation and strategies for managing these risks, for example).
  • Achieving the collaboration: The objective here is to take the practical steps to support the factual execution of the partitioning defined in the previous phase. This second level uses the collaborative process models generated at the previous level and aims to turn them into models of workflows that can be executed and orchestrated by an information system. The goal here is to obtain a computer model that a software orchestrator can run, in order to mobilize the applications, services and interfaces spread across the information systems of the various partners, according to a precise sequencing that is in step with the collaborative process models drawn from the expert-knowledge level. The difficulty of this task is twofold, since it requires finding the IT departments among the various partners that effectively cover the business-specific activities of the collaborative processes, but it also involves filling in any gaps or shortcomings by generating software interfaces (in the case of human activities) before performing the actual orchestration of the collaborative workflow models. This phase therefore concerns the transition between "design-time" and "run-time".
  • Maintain collaboration: The collaborative workflow models, once defined and executed, must then be maintained in the face of changes, disruptions or malfunctions that the collaboration may incur. This third and final level is fully dedicated to the "run-time". It is all about organizing agility within the collaborative process. It is essential to take into account the fact that at any moment, models and components obtained via the previous two phases may no longer be suited to a collaborative situation that has evolved. It is then necessary (i) to detect and diagnose this change (its occurrence and nature) and (ii) to adapt the collaborative workflow models on the fly, so as to adjust collaborative behavior (and its orchestration) to the new situation.

Defining the collaboration

This first level is divided into two objectives:

  1. to gather knowledge relevant to the desired collaborative situation,
  2. to transform this knowledge in order to propose relevant collaborative behavior models (mapping of collaborative processes, performance indicators, etc.).
  • the first objective is based on the definition of a "layered" collaborative situation metamodel, which revolves around a core of concepts specific to enterprise collaboration in general, and two upper layers ( domain and application), which contain more specialized concepts. For example, the first layer may correspond to the domain of ​​crisis management, while the second may contain concepts inherent to its application to road-transport crises. This metamodel is used to create models that are representative of the collaborative situations under consideration.
  • The second objective uses the notion of ontology, in order to link the characteristic elements of the collaborative model with the instances in our reference collaborative ontology (built from ontologies such as the MIT Process Handbook and enriched through our own work). The connections thus established will allow new elements (specific to the collaboration under study) to be integrated into the reference ontology with deduction rules applied to them, making it possible, for example, to select and order the capacities of the partners according to the objectives and context of the collaboration, or to propose relevant sets of performance indicators. This approach results in the capacity to propose multiple qualified models of collaborative behavior, which can then be selected. To do this, an evaluation process can be conducted: simulation of the models obtained or a future projection of the situation (or additional uncertainties) deduced by the models will allow their consequences to be anticipated and thus facilitate the selection process.

Achieving the collaboration

or the successful technical reconciliation of (i) activities (which make up the collaborative process) with the technical services of the partners and of (ii) information (circulating within the business-specific processes) with the technical data of the partners, this second level relies on the semantic annotation of all these concepts. These annotations, drawn particularly from domain ontologies (knowledge bases that are characteristic of a given business or industry) will then be used (for their syntactic structure as well as their semantic content) to determine which technical service (or, respectively, which technical data) best matches which business activity (or, respectively, which business-specific information).

It is also at this stage that the question of the "on the fly" generation of interfaces (to enable the mobilization of purely human activities within the workflows) will be treated. To this end, these human activities (defined in terms of inputs, outputs, functional and non-functional characteristics) will then be invoked through an HMI, providing the human beings responsible for achieving these activities with the input data and awaiting their transmission of the output data.

Finally, this level includes the orchestration itself, through the use of a "workflow engine", which, like a barrel organ producing a musical score, executes the scheme that was pre-defined on the first level and formalized on the second level, between the actors of the collaboration through their information systems.

Maintaining collaboration

Effective management of collaborative dynamics in real time requires the implementation of a detection capability (to diagnose any possible distancing of the situation under consideration from the expected state of the system) and a capacity for adaptation (so as to redefine all or part of the workflows to better adapt them to the present moment).

This detection mechanism is implemented by measuring the distance between (i) an expected situation model (i.e. the model of the initial situation, fed by information on the theoretical progress of the workflows) and a field situation model (i.e. the model of the initial situation, fed by information from the field). If these two models diverge, the behavior executed through collaborative processes will be deemed to be no longer relevant. Moreover, the nature of this divergence (i.e. what part of the model is experiencing divergence) will allow us to know what caused it.

Using the above information (and in particular the causes of divergence), an adjustment will be made by looping back to one of the "design-time" levels.

Conceptual framework

If the above three levels describe the layers of the approach taken by the IO research axis, it is important to mention that intersecting these three levels are the abstraction planes for knowledge management:

  • The "data" plane corresponds to the emission, transmission and reception of digital signals or identified values. It includes such diverse data sources as sensors, open data, social networks, reports or statements transmitted by human actors, etc.
  • The "information" level provides a semantic interpretation of the previous level data to feed formal models (e.g. when data on the position of a victim becomes an icon or a symbol on a geographical map of the site).
  • The "knowledge" level corresponds to the use of information for the generation of new knowledge (e.g. when all the positions of known victims on a site map can be used to define an optimal circuit for relief workers).

Given these considerations, the structure of the work of the IO research axis can be placed within the following conceptual framework:

Areas of application

The work of the IO research axis concern four main areas of application. These areas provide the means to support the evaluation of results, but they also generate specific constraints:

  • Crisis management system: when a crisis occurs, a large number of institutional and private actors must move into action, each according to their specific skills, but with the overriding need to coordinate. This is a type of collaborative situation where the heterogeneity of the actors is an extremely relevant factor. Furthermore, due to the instability inherent in these types of situations, agility is critical to the success of the collaboration.
  • Transport system: while passenger transport networks (public transport, road networks) are a juxtaposition of interlinked systems, they have relatively little influence on each other. Issues concerning the interoperability, collaboration and agility of these networks, in the context of intermodal management objectives (and the transformation of this group of networks into a network of networks through mediation), are significant issues in the move towards smart and sustainable cities.
  • Health system: collaboration here is highly asynchronous (the actors cannot be mobilized simultaneously), highly regulated, and reliant on actors with diverse skills and with different levels of autonomy. Furthermore, the information systems involved are of disparate levels of maturity (DMP, paper file, informal exchange ...). Again, the critical nature of this type of collaborative situation is undeniable. A noteworthy example is the highly specific case of organizing the care of patients in their own homes.
  • Logistics system: this field concerns collaborations that are either opportunistic in nature or established between actors working primarily in manufacturing (construction, production, distribution). Management of the chain between suppliers and customers can be considered as a collaborative situation (more or less permanent), for which the tools and approaches developed within the IO research axis may be relevant, at both the business-specific and technical level.

    To be competitive, supply chains must be able to analyse and to evaluate, in real-time, critical differences between the short-term planned actions and the actual performed actions generating states of undesirable or unacceptable risk. The authors propose in this study, a method for monitoring the dynamic evolution of risk associated to delays affecting the transportation operations. They use the failure mode and effects analysis around failure scenarios and they evaluate risk using probability and cost. A failure scenario probability is estimated dynamically in discrete points based on event occurrences during the process execution. Delay risk is then assessed on-line and preventive actions can be undertaken before execution ended. The implementation of this method is performed by monitoring a delivery process facing risks associated to delays in the transport stream.

    With enterprise collaboration becoming increasingly frequent, the ability of an enterprise to cooperate with others has become one of the core factors in gaining competitive advantage. This trend has led to an urgent requirement to improve cooperation ability. To this end, model-based systems engineering is being adapted so that it can be used to represent and simulate the working processes of enterprises. Model-to-model mappings and transformations, as important aspects in model-based systems engineering, have become two of the key factors in improving the cooperation capabilities of enterprises. However, the foundations for achieving automatic model-to-model transformation have not yet been built. Normally, model transformation rules are built on the basis of model mappings, and model mappings concern semantic or syntactic representations. One of the difficulties in achieving model-to-model mappings and transformations lies in detecting the semantics and semantic relations that are conveyed in different models. This paper presents an automatic model-to-model mapping and transformation methodology, which applies semantic and syntactic checking measurements to detect the meanings and relations between different models automatically. Both of the semantic and syntactic checking measurements are combined into a refined meta-model based model transformation process. To evaluate the performance of this methodology, we demonstrate its applicability with a realistic example.

    With an increasing background in inter-enterprise collaboration and interoperability, the automatic deduction of collaborative business processes is increasingly being viewed as a crucial research subject. The common solution is believed to involve either semantic ontologies or metamodeling, which can be combined with semantic algorithms or transformation rules. However, from the viewpoint of enterprises, the modeling of collaborative processes should be software integrated and can be changed to workflow. The design of the targeted collaborative process model does not fit the need. This has led to a lack of concepts and transformation rules for the ontology or metamodel. In this paper, a new collaborative process model called collaborative process cartography is designed. Related collaborative ontology and its knowledge-expanding rules have also been updated. Collaborative ontology contains essential concepts for the collaborative situation and includes the rules and algorithms for process deduction. A prototype for the supporting tools is also provided.

    Enterprise applications and software systems need to be interoperable in order to achieve seamless business across organizational boundaries and thus realize virtual networked organizations. Our proposition can be considered as an interoperability project selection approach and is based on three steps: (1) Modelling both collaborative business processes and potential related interoperability projects; (2) Evaluating the accessibility of each project regarding the current state of the organization; (3) Simulating each project and assessing the associated performance. These results are finally projected on a comparison matrix used as a decision support to select the most appropriate interoperability solution. An application case extracted from the French aerospace sector demonstrates the applicability and the benefits of the proposition.

  • Impact of the integration of tactical supply chain planning determinants on performance

    In fulfilling customers’ orders, one of the goals of tactical supply chain planning is to satisfy the customers in terms of delivery efficiency, delivery quantity accuracy and on-time delivery. These performance objectives can be impacted by the way firms plan each of the three phases of the supply chain: procurement, production and distribution. Though the link between each of these phases and supply chain performance has been studied in extant literature, very few authors have considered all three phases at the same time. By adopting an integrated approach, this paper therefore aims to study the manner in which, taken together in one model, the planning determinants of the different phases impact on supply chain performance. It is important for managers to understand, from a holistic and integrated perspective, how a given combination of the planning determinants of the supply chain functions impacts positively or negatively on the performance of the supply chain. To carry out this study, this paper starts by proposing an integrated framework that is based on the SCOR model and the customer order decoupling point (CODP), followed by a five-step methodology for tactical supply chain planning. Then, using an analytical model and simulations, and based on a numerical example, it shows how the proposed methodology can be applied in a given decision-making situation. Our results enabled to identify the worst and the best combinations of planning determinants.

  • Supporting interoperability of collaborative networks through engineering of a service-based Mediation Information System (MISE 2.0)

    References :
    The Mediation Information System Engineering project is currently finishing its second iteration (MISE 2.0). The main objective of this scientific project is to provide any emerging collaborative situation with methods and tools to deploy a Mediation Information System (MIS). MISE 2.0 aims at defining and designing a service-based platform, dedicated to initiating and supporting the interoperability of collaborative situations among potential partners. This MISE 2.0 platform implements a model-driven engineering approach to the design of a service-oriented MIS dedicated to supporting the collaborative situation. This approach is structured in three layers, each providing their own key innovative points: (i) the gathering of individual and collaborative knowledge to provide appropriate collaborative business behaviour (key point: knowledge management, including semantics, exploitation and capitalisation), (ii) deployment of a mediation information system able to computerise the previously deduced collaborative processes (key point: the automatic generation of collaborative workflows, including connection with existing devices or services) (iii) the management of the agility of the obtained collaborative network of organisations (key point: supervision of collaborative situations and relevant exploitation of the gathered data). MISE covers business issues (through BPM), technical issues (through an SOA) and agility issues of collaborative situations (through EDA).

    Each year, more than 400 natural disasters hit the world. To be more responsive, humanitarians organize stocks of relief items. It is an issue to know the quantity of items to be stored and where they should be positioned. Many authors have tried to address this issue both in industrial and humanitarian environments. However, humanitarian supply chains today do not perform correctly, particularly as regards resilience and efficiency. This is mainly due to the fact that when a disaster occurs, some hazards can strongly impact the network by destroying some resources or collapsing infrastructure. The expected performance of the relief response is consequently strongly decreased. The problem statement of our research work consists in proposing a decision-making support model in artificial intelligence dedicated to the humanitarian world and capable of designing a coherent network that is still able to adequately manage the response to a disaster despite failures or inadequacies of infrastructure and potential resources. This contribution is defined through a Stochastic Multi-Scenarios Program as a core and a set of extensions. A real-life application case based on the design of a humanitarian supply chain in Peru is developed in order to highlight the benefits and limits of the proposition.

    Business-IT alignment nowadays has become crucial, with the expansion of service-based information systems and the need to collaborate with external partners. This research work therefore presents a hybrid service composition mechanism coupling logic-based and syntactic matchmaking of services and messages to transform a business process into an executable workflow. To meet the business requirements, this mechanism is based on both top-down and bottom-up approaches using available technical services and a generic semantic profile as pivot model. Whereas the service matchmaking focuses on the functional coverage of the generated workflow, the messageone generates the message transformation needed.

    Managing complex emergency situations is a challenging task, mainly due to the heterogeneity of the partners involved and the critical nature of such events. Whatever approach is adopted to support this objective, one unavoidable issue is knowledge management. In the context of our research project, gathering, formalising and exploiting all the knowledge and information about a given crisis situation is a critical requirement. This paper presents some research results concerning this specific topic: from a theoretical point of view, the generic dimensions of crisis characterisation are defined, while from a technical point of view, we describe a software solution able to collect that knowledge (based on meta-models and ontologies). This is used to confront the characteristics of the situation (context) with characteristics of the resources (relief system) in order to design a suitable response. Finally, an illustrative example concerning a crash between a tanker truck and a train is described.

    The challenge of this paper is to underline the capability of an Event-Cloud Platform to support efficiently an emergency situation. We chose to focus on a nuclear crisis use case. The proposed approach consists in modeling the business processes of crisis response on the one hand, and in supporting the orchestration and execution of these processes by using an Event-Cloud Platform on the other hand. This paper shows how the use of Event-Cloud techniques can support crisis management stakeholders by automatizing non-value added tasks and by directing decision-makers on what really requires their capabilities of choice. If Event-Cloud technology is a very interesting and topical subject, very few research works have considered this to improve emergency management. This paper tries to fill this gap by considering and applying these technologies on a nuclear crisis use-case.

    The aim of this paper is to review the literature in the field of supplier selection under supply chain risk management. Collected papers from 2003 to 2014 are analyzed and classified, first, according to the characteristics of the problem they deal with, secondly, according to the approach they propose, and thirdly, according to the techniques they use. The papers have been grouped into five categories: the first group relates to quantitative approaches to supplier selection, the second concerns qualitative approaches, the third consists of hybrid approaches that blend two or more different approaches together, the fourth relates to simulation approaches and the last group to artificial intelligence. The techniques used in each category are outlined. The different approaches and their associated techniques are analyzed and some recommendations are made on improving their efficiency and performance. This paper is thus a systematic scope review of journal articles and conference papers issued during this period. It brings together a collection of 124 papers on the topic of supplier selection under supply chain risk management.

    Business process management (BPM) principles are commonly used to improve processes within an organisation. But they can equally be applied to supporting the design of an Information System (IS). In a collaborative situation involving several partners, this type of BPM approach may be useful to support the design of a Mediation Information System (MIS), which would ensure interoperability between the partners' ISs (which are assumed to be service oriented). To achieve this objective, the first main task is to build a collaborative business process cartography. The aim of this article is to present a method for bringing together collaborative information and elaborating collaborative business processes from the information gathered (by using a collaborative situation framework, an organisational model, an informational model, a functional model and a metamodel and by using model transformation rules).

  • Event-driven agility of interoperability during the Run-time of collaborative processes

    The modem business environment tends to involve a large network of heterogeneous people, devices and organizations that engage in collaborative processes among themselves. Given the nature of this type of collaboration and the high degree of interoperability between partner Information Systems, these processes need to be agile in order to respond to changes in context, which may occur at any time during the collaborative situation. The objective is to build a Mediation Information System (MIS), in support of collaborative situations, whose architecture must be (i) built to be relevant to the collaborative situation under consideration, (ii) more easily integrated into the existing systems, and (iii) sufficiently agile, through its awareness of the environment and of process events, and through the way it reacts to events detected as being relevant. To apply agility mechanisms, it is crucial to detect the significant events that will lead to a subsequent evolution of the situation (detection step). Event-Driven Architecture (EDA) is used to design the structure of the part of the system that is in charge of MIS agility. This architecture takes the events into account, manages them and, if needed, uses them to trigger the adaptation of the MIS. We have defined a means to monitor the evolution of the situation. If relevant changes are detected, and if the situation does not evolve in the expected way, an adaptation is proposed. It is concluded that the principles of detection and adaptation, combined with the responsiveness of the system (provided by the automation of transitions), and based on Event Driven Architecture principles, together provide the agility required for collaborative processes.

    The Mediation Information System Engineering (MISE Project) aims at providing collaborating organisations with a mediation information system (MIS) in charge of supporting interoperability of a collaborative network. The MISE proposes an overall MIS design method according to a model-driven approach, based on model transformations. This MIS is in charge of managing (i) information, (ii) functions and (iii) processes among the information systems (IS) of partner organisations involved in the network. Semantic issues are accompanying this triple objective: How to deal with information reconciliation? How to ensure the matching between business functions and technical services? How to identify workflows among business processes? This article aims first at presenting the MISE approach, second at defining the semantic gaps along the MISE approach and third at describing some past, current and future research works that deal with these issues. Finally and as a conclusion, the very design-oriented' previous considerations are confronted with 'runtime' requirements.

    During a crisis, the main goal for decision-makers consists in restoring a stabilised nominal mode. The stakeholders face considerable pressure and drastic constraints in response time and coordination. This study proposes a method to support these stakeholders in making responsive and accurate decisions while carrying out a performance evaluation of the activities that run during the crisis-response process. This method is composed of four steps: (1) characterisation of the crisis-response system, (2) selection of system components to evaluate in priority, (3) determination of performance dimensions to consider and (4) creation of indicators. Currently, performance evaluation is only used subsequent to a crisis, due to difficulties in gathering and aggregating information into trustable performance indicators. This paper proposes a method to obtain a relevant and dynamic decision-support system. Decision-makers will use it to resolve the crisis based on performance evaluation, in addition to the essential experience they undergo. A case study of crisis management within the French Red Cross non-governmental organisation is developed, through a Web-based prototype, in order to explain how performance indicators can both support crisis-response management and improve the collaboration of stakeholders.

    Many authors have highlighted gaps at the interfaces between supply chains (SCs) and demand chains. Generally, the latter tends primarily to be 'agile' by maximising effectiveness and responsiveness while the former tends to be 'lean' by maximising efficiency. When, in the SC, disruptions (that lead to stock-out situations) occur after customer orders have been accepted, managers are faced with the problem of maximising customer satisfaction while taking into consideration the conflicting objectives of the supply and demand sides of the order fulfilment process. This article proposes a cross-functional multi-criteria decision-making (advanced available-to-promise) tool that provides different strategic options from which a solution can be chosen. It also proposes a performance measurement system to support the decision-making and improvement process. The results of some experimental tests show that the model enables to make strategic decisions on the degree of flexibility required to achieve the desired level of customer service.

    Quality control lead times are one of most significant causes of loss of time in the pharmaceutical and cosmetics industries. This is partly due to the organization of laboratories that feature parallel multipurpose machines for chromatographic analyses. The testing process requires long setup times and operators are needed to launch the process. The various controls are non-preemptive and are characterized by a release date, a due date and available routings. These quality processes lead to significant delays, and we therefore evaluate the total tardiness criterion. Previous heuristics were defined for the total tardiness criterion, parallel machines, and setup such as apparent tardiness cost (ATC) and ATC with setups (ATCS). We propose new rules and a simulated annealing procedure in order to minimize total tardiness. (C) 2010 Elsevier Ltd. All rights reserved.

    Vendor Managed Inventory (VMI) is currently seen as a short-term replenishment pull system. Moreover, VMI is usually synonymous with a distribution context and stable demand. However, industrial partners are faced with uncertainty in the context of a B to B relationship. Thus, an adaptation of the actors' planning processes is needed and the question is posed of the interest of VMI in a context of uncertain demand. The purpose of this paper is firstly to analyze the link between VMI and pull logic. Secondly, we explore the extension of VMI notions to the relationship between industrial partners and we confront VMI with uncertain demand in terms of trend, vision of the trend and variability in order to verify the usual stable demand assumption. We also present an integration of VMI into a simulation tool called LogiRisk that we have developed for the evaluation of risks of in supply chain collaboration policies, and a small case study.

    This study is focused on decision support in the context of product and service development projects. Decision support requires the capacity to characterize the current state of the project (performance evaluation) and the decision-maker's point of view. However, the different projects' stakeholders do not have the same needs in terms of performance evaluation to support their decision-making processes. Furthermore, in some cases controlling project performance using the elementary components of the Iron Triangle (Cost, Time and Quality) alone seems inefficient. This paper proposes a new multi-dimensional Project Performance Measurement System that would enable managers to deal with the volume of data. The proposition integrates the only character of each project (tasks, objectives, decision-makers personality and competences), several good practices in terms of universal project management dimensions on the one hand, and in terms of performance analysis on the other hand. Then, we show how an aggregation tool called MACBETH is used to analyze the performance measures according to project managers' own performance interests. A case study illustrates the proposed system. (C) 2010 Elsevier Ltd. and IPMA. All rights reserved.

  • An enterprise modelling approach for better optimisation modelling: application to the humanitarian relief chain coordination problem

    References :
    Humanitarian supply chains (HSC) can be considered a new research area. The number of applied scientific publications has considerably increased over the past 15 years. About half of this research work uses quantitative techniques as optimisation decision-support systems. But due to the recentness of this academic area, researchers are finding it difficult to develop accurate, and above all, reliable mathematical models to support their steps towards improvement. This is particularly true concerning the crucial problems of coordination in HSCs. This paper tackles the issue by developing an original quantitative modelling support method. Based on enterprise modelling methodologies, we propose a business process modelling approach that helps in understanding, analysing, evaluating and then developing the formal expression of an HSC. Such a model, therefore, clearly has an added value for practitioners and should enable relevant quantitative models to be produced. Finally, an application on the emergency response processes of the International Federation of Red Cross is detailed in order to validate the relevance and the applicability of our proposal. This experiment allows all the variables and parameters that should be useful for improving the efficiency of the network to be identified.

  • A model to define and assess the agility of supply chains: building on humanitarian experience

In: International Journal of Physical Distribution & Logistics Management 40.8 (2010). pp. 722--741. ISSN: 0960-0035. DOI: 10.1108/09600031011079355.
    Purpose - By constantly working in environments with high degree of uncertainty, humanitarian organizations end up becoming specialists in the implementation of agile systems. Their counterparts in profit-making organizations have a lot to learn from them in this domain. Volatility of demand, imbalance between supply and demand and disruptions are all factors that affect commercial supply chains and call for a high level of agility. The aims of this paper are twofold: first, to clearly define the concept of supply chain agility, and second, to build a model for assessing the level of agility of a supply chain. Design/methodology/approach - Three approaches are used in this research: literature review, case study and symbolic modeling. Findings - The paper developed first, a framework for defining supply chain agility and second, a model for assessing and improving the capabilities of humanitarian and commercial supply chains in terms of agility, based on an analysis of humanitarian approaches. Research limitations/implications - The model has been developed thanks to inputs from humanitarian practitioners and feedbacks from academics. The practical application to various humanitarian relief operations and commercial supply chains is yet to be done. Originality/value - This paper contributes significantly to clarifying the notion of supply chain agility. It also provides a consistent, robust and reproducible method of assessing supply chain agility, which seems appropriate for both humanitarian and business sectors. Finally, it is complementary to existant research on humanitarian logistics. It shows that though humanitarian professionals have a lot to learn from the private sector, the reverse is also true.

    In the modern supplier-customer relationship, Vendor Managed Inventory (VMI) is used to monitor the customer's inventory replenishment. Despite the large amount of literature on the subject, it is difficult to clearly define VMI and the main associated processes. Beyond the short-term pull system inventory replenishment often studied in academic works, partners have to share their vision of the demand, their requirements and their constraints in order to fix shared objectives for the medium/long-term. In other words, the integration of VMI implies consequences for the collaborative process that links each partner's different planning processes. In this article we propose a literature review of VMI. Based on the conceptual elements extracted from this analysis, we suggest a VMI macro-process that summarises both operational and collaborative elements of VMI.

    This paper presents an ontology-based approach for the design of a collaborative business process model (CBP). This CBP is considered as a specification of needs in order to build a collaboration information system (CIS) for a network of organizations. The study is a part of a model-driven engineering approach of the CIS in a specific enterprise interoperability framework that will be summarised. An adaptation of the Business Process Modelling Notation (BPMN) is used to represent the CBP model. We develop a knowledge-based system (KbS) which is composed of three main parts: knowledge gathering, knowledge representation and reasoning, and collaborative business process modelling. The first part starts from a high abstraction level where knowledge from business partners is captured. A collaboration ontology is defined in order to provide a structure to store and use the knowledge captured. In parallel, we try to reuse generic existing knowledge about business processes from the MIT Process Handbook repository. This results in a collaboration process ontology that is also described. A set of rules is defined in order to extract knowledge about fragments of the CBP model from the two previous ontologies. These fragments are finally assembled in the third part of the KbS. A prototype of the KbS has been developed in order to implement and support this approach. The prototype is a computer-aided design tool of the CBP. In this paper, we will present the theoretical aspects of each part of this KbS as well as the tools that we developed and used in order to support its functionalities. (C) 2009 Elsevier B.V.

    This paper discusses the difficulty of controlling a complex project caused by the great number of performance indicators. The problem studied is how to allow project managers to better control the performance of their projects. From a literature review we noted several critical aspects to this problem: there are many dimensions for evaluating project performance (cost, time, quality, risk, etc.); performance factors should be able to be relevantly aggregated for controlling the project, but no formalized tool exists to do this. We suggest a method to facilitate project performance analysis via a multi-criteria approach. The method focuses on three particular axes for the analysis of project performance: project task, performance indicator categories, and a breakdown of the performance triptych (Effectiveness. Efficiency, Relevance). Finally, the MACBETH method is used to aggregate performance expressions. An application case study examining a real project management situation is included to illustrate the implementation. (c) 2009 Elsevier B.V. All rights reserved.

    In a collaborative context, the integration of industrial partners deeply depends on the ability to use a collaborative architecture to interact efficiently. In this paper, we propose to tackle this point according to the fact that partners of the collaboration respect the Service-Oriented Architecture (SOA) paradigm. We propose to design such a collaborative architecture according to Model-Driven Architecture (MDA) principles. We aim at using business models to design a logical model of a solution (logical architecture) as a principal step to reach the final collaborative solution.

    The purpose of facility location models is to select a set of facilities (warehouses, plants, public facilities, antennas, etc.) to be implanted over a given area in order to satisfy the needs of all or part of the customers within this area. In this paper, the objective is to minimize the sum of the costs of investment, production and distribution while satisfying all customers' demands. We introduce a new type of facility location model, in which the global cost incurred for each established facility is a concave function of the quantity q delivered by this facility. We introduce some properties of an optimal solution and derive heuristic algorithms and a branch and bound method from these properties. Numerical examples illustrate this approach.

    When designing a new family of products, designers and manufacturers must define the product family and its supply chain simultaneously. At the very first step of the design process, designers propose various solutions for the set of variants of a product family and their bill-of-materials. The second step is to select some of these variants while choosing the architecture of the supply chain. A mixed integer linear programming model is investigated that optimizes the operating cost of the resulting supply chain while choosing the product variants. This work is applied to the problem of an automotive supplier. (c) 2005 Elsevier B.V. All rights reserved.

  • Re-planning support system for make-to-order production with reserved resources

    Make-to-order production is often organized into projects with their own objectives. Such projects use strategic and critical resources that must be reserved at a strategic or a tactical planning level. When external resources need to be taken into consideration, they must be reserved based on their set of free time windows. A medium-term planning support system for the manager of a project where external resources are critical is proposed. By providing explanations for project inconsistencies, this system enables the decision-maker to restore consistency. After creating the initial medium-term plan, planning activity essentially consists in updating the existing schedule of a project when unexpected events arise. These may be due to internal or external disturbances. Indicators are proposed to help the manager follow the dynamic impact the disturbances will have on the project.

  • Handling soft constraints in hoist scheduling problems: the fuzzy approach

    The Hoist Scheduling Problem (HSP) deals with the scheduling of hoists that move products between tanks in electroplating facilities that perform chemical surface treatments. In HSP, the gradual effect of soaking times (operation duration in tanks) on the quality of treatment can be represented by means of fuzzy sets: the satisfaction degree in a fuzzy interval models a quality evaluation of the chemical treatment. When temporal bounds are required, an implicit relaxation of these flexible constraints can thus be performed so as to meet the due-date. When the objective is rather a minimization of the makespan, a bi-criteria decision problem has to be dealt with that involves both the quality and the line throughput optimization. Rather than an aggregation of the two evaluations under the form of a single criterion, we propose a decision-support approach that quickly converges to a good trade-off between the two criteria.
