In the context of project planning, the objective of this thesis is to focus on the consideration, from the design phase of the project, of the various potential hazards that may arise during the project. We propose an approach for reliable estimates needed for decision-making. This approach aims to address two specific problems (i) how to evaluate a project, one might consider all possibilities, events and situations that the project could encounter during its implementation and (ii) how to address the linkages and relationships that can co-exist between risks. For this, a model for assessing the scenarios of risk-project in the mixed variables of multi-risk, multiimpact, multi-strategy of treatments and multi-dependency, is proposed. The developed model is integrated into a simulation framework for handling the entire process of project planning. A prototype computer program that supports this approach has been developed and applied in a case study for the pharmaceutical sector (conducting a clinical study)
Optimisation et planification de l'approvisionnement en présence du risque de rupture des fournisseurs by Faiza Hamdi( )

Trade liberalization, the development of mean of transport and the development economic of emerging countries which lead to globalization of supply chain is irreversible phenomen. They can reduce costs, in return, they multiply the risk of disruption from upstream stage to downstream stage. In this thesis, we focus on the inbound supply chain stage. We treat more specifically the case of a purchasing central to select suppliers and allocate the orders. Each of the suppliers cannot deliver its orders due to internal reasons (poor quality problems) or external reasons (natural disasters, transport problems). According to the selected suppliers deliver their orders or not, the transaction operation will generate a profit or loss. The objective of this thesis is to provide decision support tools to a decision maker faced with this problem by taking into account the behavior of decision maker toward risk. We proposed stochastic mixed integer linear programs to model this problem. In the first part, we focuses on the development of a decision support visual tool that allows a decision maker to find a compromise between maximizing the expected profit and minimize the risk of loss. In the second part, we integrated the techniques of estimation of risk VaR and CVaR in this problem. The objective is to help decision maker to minimize the expected cost and minimize the conditional value at risk simultanously via calculating of VaR. Result shows that the decision maker must tack into account the different scenarios of disruption regardless their probability of realisation
Analysis of the causes of delay in collaborative decision-making under uncertainty in pharmaceutical R and D projects by Saïna Hassanzadeh( Book )

2 editions published in 2012 in English and held by 2 WorldCat member libraries worldwide

Collaborative decisions may be deferred when faced with a high degree of uncertainty, especially when public health and high investments are at stake and in situations that seem non-urgent, as is the case in pharmaceutical R and D projects. This thesis investigates the causes of recurrent delay in collaborative decision-making under uncertainty, and the efficient practices to reduce this delay. To better understand the problem of delay in decision-making under uncertainty, we first review the notion of uncertainty and propose a definition of uncertainty adapted to project management. Then, the decision-making process in drug development projects is modeled, highlighting the information life cycle from its generation to its consumption i.e. the decision itself. It includes individual reflection and group interaction, clarifying how information is processed differently by decision-makers. To analyze past conflicts and anticipate future ones, based on this model, an index is defined that measures the risk of invalidating a decision a posteriori. Finally, through an in-depth interview-based approach, 252 key factors that affect decision-making are pointed out. The three most-mentioned causes of delay are: fear of uncertainty, fear of hierarchy, and difficulty of No Go decisions. Based on the identified factors, a compendium of practices is constructed for the actors of the decision-making process that help collaborative decisions to be formed, matured, digested, respected, and finally executed
Approche pour la construction de modèles d'estimation réaliste de l'effort/coût de projet dans un environnement incertain : application au domaine du développement logiciel by Safae Laqrichi( Book )

Software effort estimation is one of the most important tasks in the management of software projects. It is the basis for planning, control and decision making. Achieving reliable estimates in projects upstream phases is a complex and difficult activity because, among others, of the lack of information about the project and its future, the rapid changes in the methods and technologies related to the software field and the lack of experience with similar projects. Many estimation models exist, but it is difficult to identify a successful model for all types of projects and that is applicable to all companies (different levels of experience, mastered technologies and project management practices). Overall, all of these models form the strong assumption that (1) the data collected are complete and sufficient, (2) laws linking the parameters characterizing the projects are fully identifiable and (3) information on the new project are certain and deterministic. However, in reality on the ground, that is difficult to be ensured. Two problems then emerge from these observations: how to select an estimation model for a specific company? and how to conduct an estimate for a new project that presents uncertainties?The work of this thesis interested in answering these questions by proposing a general estimation framework. This framework covers two phases: the construction phase of the estimation system and system usage phase for estimating new projects. The construction phase of the rating system consists of two processes: 1) evaluation and reliable comparison of different estimation models then selection the most suitable estimation model, 2) construction of a realistic estimation system from the selected estimation model and 3) use of the estimation system in estimating effort of new projects that are characterized by uncertainties. This approach acts as an aid to decision making for project managers in supporting the realistic estimate of effort, cost and time of their software projects. The implementation of all processes and practices developed as part of this work has given rise to an open-source computer prototype. The results of this thesis fall in the context of ProjEstimate FUI13 project
Proposition d'indicateurs de robustesse basés sur la prise en compte des risques afin d'évaluer les tournées de transport routier de marchandises by Antoine Clément( )

2 editions published in 2019 in French and held by 2 WorldCat member libraries worldwide

The work presented in this thesis aims to answer a problem of decision support for the selection of a delivery schedule in the field of road freight transport and, particularly, for the last mile delivery. The role of the planner is crucial to ensure the respect of the customer's requirements and the success of the transport company. More than building a feasible planning, the planner must select, among several possible schedules, the one that ensures the best efficiency of the resources of the company whatever the situations to come. Indeed, tours are frequently confronted with a multitude of disturbances, whether endogenous or exogenous. The problem addressed in this thesis is: "How to help a planner to select a schedule in a risky context?". Two main contributions are presented in this thesis. Our first contribution aims to propose a mechanism for automatic identification and evaluation of the risks related to a daily delivery schedule. These mechanisms are based on the characterization of generic dangers that can be automatically instantiated on a delivery schedule activity based on contextual characteristics of this activity. Thus, when a planning activity is confronted with a danger, a risk is generated on this activity to materialize the execution deviations (delays) generated by the disruptive event. A methodology for evaluating the impact of risks on the execution of the tours and risk scenarios, based on the characteristics (probability, impacts) of each risk, is also presented. Our second contribution consists of the proposal of specific indicators (the maximum delay of a delivery, the probability of respecting constraints of hour for the customer and the minimum of satisfactions) to measure the robustness of the delivery schedules in the face of the disturbances and a methodology for exploiting these indicators. The proposed indicators measure of the capacity of the schedule to meet the customer's requirements (quantity delivered, delivery schedule). An approach to exploit these indicators in the phase of selecting a schedule as in the aid to the negotiation of flexibility with the client is proposed. The work of this thesis is part of the ANR (National Research Agency) Smart Planning project. A case study from the project partner companies illustrates the contributions
Contribution à l'ordonnancement des activités de maintenance sous contrainte de compétence : une approche dynamique, proactive et multi-critère by François Marmier( Book )

2 editions published in 2007 in French and held by 2 WorldCat member libraries worldwide

Les services de maintenance interviennent pour maintenir ou remettre en état de bon fonctionnement les équipements. A travers la réduction de l'indisponibilité des équipements, ils participent à l'amélioration de la compétitivité des entreprises. Le service de maintenance est composé entre autre, de ressources humaines qui réalisent les tâches de maintenance. L'un des problèmes du manager de ce service est alors de trouver, pour chaque tâche, quelle ressource la traitera et quand. Dans cette thèse, nous nous intéressons à un problème d'affectation et d'ordonnancement en prenant en compte les compétences des ressources humaines. Les différences de compétence sont peu intégrées dans les modèles de la littérature. Les ressources sont en effet souvent considérées comme identiques ou n'ayant qu'une compétence. Les différents types de tâches présentent aussi des spécificités qui sont peu retrouvées dans les approches de la littérature. Cette problématique se retrouve dans d'autre contexte que celui de la maintenance et touche plus généralement l'affectation et l'ordonnancement de l'activité d'un service. Nous proposons une approche de résolution dynamique pour un problème mono-critère d'affectation et d'ordonnancement des activités de maintenance dans le contexte de la maintenance, différents critères concernant les ressources et les tâches sont importants. Nous proposons donc une extension de l'approche dynamique mono-critère au multi-critère. Certaines données utilisées dans l'affection et l'ordonnancement sont incertaines. Pour anticiper la présence de ces incertitudes nous proposons une approche dynamique, proactive à un problème multi-critère d'affectation et d'ordonnancement d'activité de maintenance en contexte incertain. Toutes ses approches font appel à une méthode d'amélioration par modification partielle de l'ordonnancement, inspirée de la méthode du kangourou
Identification of Function Points in Software Specifications Using Natural Language Processing by Munshi Asadullah( )

1 edition published in 2015 in English and held by 1 WorldCat member library worldwide

The inevitable emergence of the necessity to estimate the size of a software thus estimating the probable cost and effort is a direct outcome of increasing need of complex and large software in almost every conceivable situation. Furthermore, due to the competitive nature of the software development industry, the increasing reliance on accurate size estimation at early stages of software development becoming a commonplace practice. Traditionally, estimation of software was performed a posteriori from the resultant source code and several metrics were in practice for the task. However, along with the understanding of the importance of code size estimation in the software engineering community, the realization of early stage software size estimation, became a mainstream concern. Once the code has been written, size and cost estimation primarily provides contrastive study and possibly productivity monitoring. On the other hand, if size estimation can be performed at an early development stage (the earlier the better), the benefits are virtually endless. The most important goals of the financial and management aspect of software development namely development cost and effort estimation can be performed even before the first line of code is being conceived. Furthermore, if size estimation can be performed periodically as the design and development progresses, it can provide valuable information to project managers in terms of progress, resource allocation and expectation management. This research focuses on functional size estimation metrics commonly known as Function Point Analysis (FPA) that estimates the size of a software in terms of the functionalities it is expected to deliver from a user's point of view. One significant problem with FPA is the requirement of human counters, who need to follow a set of standard counting rules, making the process labour and cost intensive (the process is called Function Point Counting and the professional, either analysts or counters). Moreover, these rules, in many occasion, are open to interpretation, thus they often produce inconsistent counts. Furthermore, the process is entirely manual and requires Function Point (FP) counters to read large specification documents, making it a rather slow process. Some level of automation in the process can make a significant difference in the current counting practice. Automation of the process of identifying the FPs in a document accurately, will at least reduce the reading requirement of the counters, making the process faster and thus shall significantly reduce the cost. Moreover, consistent identification of FPs will allow the production of consistent raw function point counts. To the best of our knowledge, the works presented in this thesis is an unique attempt to analyse specification documents from early stages of the software development, using a generic approach adapted from well established Natural Language Processing (NLP) practices
Modeling and analysis of propagation risks in complex projects : application to the development of new vehicles by Hadi Jaber( )

1 edition published in 2016 in English and held by 1 WorldCat member library worldwide

La gestion de projets complexes nécessite d'orchestrer la coopération de centaines de personnes provenant de diverses entreprises, professions et compétences, de travailler sur des milliers d'activités, livrables, objectifs, actions, décisions et risques. En outre, ces nombreux éléments du projet sont de plus en plus interconnectés, et aucune décision ou action n'est indépendante. Cette complexité croissante est l'un des plus grands défis de la gestion de projet et l'une des causes de l'échec du projet en termes de dépassements de coûts et des retards. Par exemple, dans l'industrie automobile, l'augmentation de l'orientation du marché et de la complexité croissante des véhicules a changé la structure de gestion des projets de développement de nouveaux véhicules à partir d'une structure hiérarchique à une structure en réseau, y compris le constructeur, mais aussi de nombreux fournisseurs. Les dépendances entre les éléments du projet augmentent les risques, car les problèmes dans un élément peuvent se propager à d'autres éléments qui en dépendent directement ou indirectement. La complexité génère un certain nombre de phénomènes, positifs ou négatifs, isolés ou en chaînes, locaux ou globaux, qui vont plus ou moins interférer avec la convergence du projet vers ses objectifs.L'objectif de la thèse est donc de réduire les risques associés à la complexité des projets véhicules en augmentant la compréhension de cette complexité et de la coordination des acteurs du projet. Pour ce faire, une première question de recherche est de prioriser les actions pour atténuer les risques liés à la complexité. Puis, une seconde question de recherche est de proposer un moyen d'organiser et de coordonner les acteurs afin de faire face efficacement avec les phénomènes liés à la complexité identifiés précédemment.La première question sera abordée par la modélisation de complexité du projet en analysant les phénomènes liés à la complexité dans le projet, à deux niveaux. Tout d'abord, une modélisation descriptive de haut niveau basée facteur est proposé. Elle permet de mesurer et de prioriser les zones de projet où la complexité peut avoir le plus d'impact. Deuxièmement, une modélisation de bas niveau basée sur les graphes est proposée. Elle permet de modéliser plus finement les éléments du projet et leurs interdépendances. Des contributions ont été faites sur le processus complet de modélisation, y compris l'automatisation de certaines étapes de collecte de données, afin d'augmenter les performances et la diminution de l'effort et le risque d'erreur. Ces deux modèles peuvent être utilisés en conséquence; une première mesure de haut niveau peut permettre de se concentrer sur certains aspects du projet, où la modélisation de bas niveau sera appliquée, avec un gain global d'efficacité et d'impact. Basé sur ces modèles, certaines contributions sont faites pour anticiper le comportement potentiel du projet. Des analyses topologiques et de propagation sont proposées pour détecter et hiérarchiser les éléments essentiels et les interdépendances critiques, tout en élargissant le sens du mot polysémique "critique".La deuxième question de recherche sera traitée en introduisant une méthodologie de « Clustering » pour proposer des groupes d'acteurs dans les projets de développement de nouveaux produits, en particulier pour les acteurs impliqués dans de nombreuses interdépendances liées aux livrables à différentes phases du cycle de vie du projet. Cela permet d'accroître la coordination entre les acteurs interdépendants qui ne sont pas toujours formellement reliés par la structure hiérarchique de l'organisation du projet. Cela permet à l'organisation du projet d'être effectivement plus proche de la structure en « réseau » qu'elle devrait avoir. L'application industrielle aux projets de développement de nouveaux véhicules a montré des résultats prometteurs pour les contributions aux deux questions de recherche
Evaluation model of a supply chain's sustainability performance and risk assessment model towards a redesign process : case study at Kuehne + Nagel Luxembourg by Anne Winter( )

1 edition published in 2016 in English and held by 1 WorldCat member library worldwide

Dans le présent travail, le concept de durabilité a été redéfini pour que la compréhension commune puisse être garantie. Un modèle d'évaluation du degré de durabilité d'une chaîne logistique existante a été conçu par la suite. Ce modèle a été testé de façon empirique à travers une étude de cas. En appliquant l'amélioration continue, il faut que cette évaluation soit suivie d'un processus de reconception de la chaîne logistique en question. Cependant, Il est important qu'une évaluation des risques soit réalisée auparavant. Pour cette raison, un modèle de quantification des risques a été développé. Le modèle peut considérer soit les risques débouchant sur une reconception, soit les risques dus à une reconception. Une étude de cas basée sur les risques débouchant sur une reconception de la chaîne logistique a été mise en place pour prouver l'applicabilité du modèle dans un environnement réel. Les résultats qui découlent du modèle doivent être considérés comme étant une aide à la décision
