Non-decoupling iterative scheduling algorithm for coupled activities set in concurrent design

A matrix, multi-parameter WTM is established to analysis the parallel or serial relations among coupled activities, the iterative modes are studied in terms of design resources, and the influencing law of design resources and self-study on iterative workload, time and cost are deeply analyzed. A non-decoupling mixed iteration algorithm is proposed based on GA, which schedules coupled activities. The algorithm is demonstrated by a design case, and the results shows that it is not only effective and efficient to optimize design iterative process, but also scientific, simple and easy to use.
