A New Framework for Collaborative Set-Based Design: Application to the Design Problem of a Hollow Cylindrical Cantilever Beam

In the New Product Development processes, there are usually interacting multiple actors with multiple design objectives. Design objectives of the actors can be contradictorily related and design modifications related to some objectives may generate negative impacts on the other actors. Therefore conflicts may occur. We present a multi-actor design platform that is capable of preventing potential conflicts with ensuring the satisfaction and progress of the actors at a certain level. An indicator of wellbeing is developed in order to indentify the satisfaction and progress states of the actors. We use Set-based design approach and Constraint Satisfaction Problem solving techniques to deal with the multi-actor, multi-objective design problem. We apply our collaborative design approach to a multi-actor multiobjective engineering design problem of a hollow cylindrical cantilever beam with a load applied at the unsupported end.
