Shortcomings of current conflict resolution methods in solving the problems of disordered competition for design resource in networked design environment are analyzed. By introducing the design structure matrix (DSM) to the planning process of design task, a mathematic description model in collaborative design considering the conflict causes as resource conflict, process conflict and design conflict is given. The reconstruction method of the DSM as well as the DSM based matrix search algorithm is given, based on which the problem of design locking and long waiting because of limited resource in the collaborative design process can be successfully solved. Finally, the design of a bridge crane is used as an example to demonstrate the successful application of the proposed resource conflict resolution strategy in collaborative Design environment.
