Abstract:
Engineering change management is a special form of problem solving where many rules must be followed to satisfy the requirements of product changes. As engineering change has great influence on the cycle and the cost of product development， it is necessary to anticipate design changes （DCs） in advance and estimate the influence effectively. A process simulation-based method for engineering change management is proposed incorporating multiple assessment parameters. First， the change propagation model is established， which includes the formulation of change propagation influence， assessment score of DC solution. Then the optimization process of DC solution is introduced based on ant colony optimization （ACO）， and an optimization algorithm is detailed to acquire the optimal DC solution automatically. Finally， a case study of belt conveyor platform is implemented to validate the proposed method. The results show that changed requirement of product can be satisfied by multiple DC solutions and the optimal one can be acquired according to the unique characteristics of each solution.
