Manufacturers must always develop products faster and better to satisfy their client’s requirements. To help them, we have developed and experimented with a methodology to improve the management process by connecting it with the design process. An issue for the project manager is to select an organization from among the possible ones to schedule the project tasks in order to reach the targets in terms of costs, duration, quality, and so forth. This constitutes a tricky operation, because many options defined during the design can be associated to each task of the project. Choosing and optimizing the schedules is a combinatorial problem which can be solved by heuristic. This document explores the use of evolutionary algorithms to help the decision maker. It introduces the industrial context and presents our methodology to connect the design and project management processes, expressing the problem as a multi-objective optimization one. We detail the scenarios selection process and demonstrate which performances are obtained.
