PhD Thesis Abstract - Decision support in distributed multi-project management: A local approach for medium-term planning
The project framework is the most commonly used way to represent company’s activities. The projects are generally broken down into human resources, material resources and suppliers. This work focuses on the study of one decisional centre with respect to its direct environment; this study consists of an analysis of the local decisions to be taken when scheduling a project with respect to its interactions and dependences with other decisional centres.
We start by an identification of the industrial needs, followed by a presentation of the studies related to project management either when data are well-known or when data are uncertain, as well as multiple projects scheduling. Our approach deals with two main problems: detection and explanation of inconsistencies and conflicts (in order to help solve them) on the one hand, uncertainty management on the other hand.
Indeed, the dynamic aspect of the problem can lead the decision maker to a situation where its scheduling is no longer valid, and has to be reconsidered. At this point, we present the decision support system (DSS) as a way to point out conflicts. This tool suggests decision ways and/or negotiation with other projects.
We extended this inconsistency explanations search method to the project scheduling problems under imprecise or uncertain data. The imprecise or uncertain elements are represented using the fuzzy approach. This work on uncertain data led us to consider the case of fuzzy PERT, for which a solving method is proposed when the project graph is a serial-parallel one. If no hypothesis can be done on the graph structure, a heuristic is also introduced.
The results presented in this work are based on a real industrial problem: satellite integration management problem, in the Assembly, Integration and Test department of the Astrium company. Once the general components of the problem were specified, a set of problems were defined, on which a C++ preliminary version of the DSS could be tested.
