Laboratory for Analysis and Architecture of Systems
The research work of the MOGISA group concentrates on studying systems in which activities must be executed by resources. Execution of activities is subject to constraints related to the use and availability of resources, to integration into projects or processes. The research topics apply to project management, to manufacturing (workshops) and services (transportation, telecommunications, health, maintenance, etc.). One common and frequent characteristic of these domains is their socio-technical entanglement, with man occupying a central position and a variety of roles.
The problems mentioned above are related to tasks assignment and scheduling, to the planning of supply, manufacturing and distribution. Such problems may be restricted to some manufacturing units within the same enterprise or may apply to a complete supply chain integrating a network of partner enterprises.
The objective is to define models, methods and tools providing supports to analyse, evaluate, design, and pilot systems of activities in an uncertain and disturbed environment. The research is focused on model genericity, performance and consistency of methodologies, tools reusability. Such requirements can be achieved through using techniques from Operations Research (mathematical programming, graph theory, tree-search methods, metaheuristics), developing formal models and techniques derived from Artificial Intelligence (Constraint Propagation/Satisfaction/Programming).
The research work is presented following four major topics which are:
