面向社群的广域产品设计网络是一种协同产品开发的新模式。该模式中，协作伙伴的选择范围扩展到广域的网络社群成员。由于无法准确了解候选社群成员的准确属性，为设计网络的组建带来了困难。针对这一问题，提出了一种基于招投标机制的社群型协同产品设计网络组建方法，给出了基于扩展合同网协议的招投标流程。基于投标信息，同时考虑投标方的虚报利润，采用基于遗传算法的多轮二次招投标求解满足项目周期前提下项目总支付款最低的子项目最优分配方案，使协同产品设计网络的组建成本最低。算例分析表明，该方法能有效消除投标方的虚报利润，为面向社群的协同产品设计网络的组建提供了一种可操作的方法。

英文摘要：

Community-oriented collaborative design is an emergent form of collaborative product development, in which the range of collaborative partners extends to wide area community members. It is difficult to construct the organization network because the accurate features of the wide area community members are hard to access. Aiming at this problem, an organization network constructing method based on bidding mechanism is proposed. First, the bidding process based on contract net with confirmation protocol （CNCP） is presented. Then, considering the false profit declared by the bidders, a multiple rounds bidding process combined with genetic algorithm （GA） is used to get the best sub-projects allocation scheme, in which the total payment of sub-projects is minimal and the project due time is satisfied. A case analysis shows that the method can eliminate the false profit declared by the bidders and provides an operable way to construct network organization for community-oriented collaborative design.
