Scheduling Design Activities with Interdependency and Resource Constraints in a Civil Aircraft Development
This paper investigates the problems of project scheduling at the design stage of the development of a civil aircraft. Such a complex system development is characterised by a dynamic environment and uncertainties concerning the duration of activities. Moreover, design teams responsible for the development of a subsystem need to manage interactions with other teams. We describe a variant of the standard Resource Constrained Scheduling Problem with fully elastic activities that takes into account the dependencies between design teams as new constraints (Contract Dependency Constraints). Moreover, we detail the Energy-Precedence Constraints, which is a new way to model precedence between activities in a concurrent engineering based project. We propose to model our problem as a discrete Constraint Satisfaction Problem. Implementing this model uses a Constraint Logic Programming environment. Our approach is flexible enough to be implemented within the aerospace industry, by facilitating cooperation between design teams and providing practical schedules for the decision support process at different managerial levels.
