社会化产品开发众包设计任务间加权网络建模与模块划分

依据社会化产品开发众包设计任务模块划分的需要，针对产品原子设计任务之间关联的含糊性，采用11级标度加权网络来描述它们的关系并进行剪枝的原理与方法。以模块内聚合度最大、模块间耦合度最小、协作设计难度最低为目标函数，建立产品社会化设计众包任务模块划分的优化模型，采用蚁群算法进行求解；论述原子设计任务之间在功能和结构上信息交流相关度、承包方协作难度的计算方法，给出众包任务模块划分的原则、步骤，并举实例说明所提出方法的可行性。

Weighted Network Modeling and Module Partitioning Among Crowdsourcing Design Tasks for Social Product Development

According to the needs of module division for crowdsourcing design tasks under social product development and aiming at the ambiguity of the correlation among product atomic design tasks, the elementary theory and methods that an 11-level scale weighted networks was used to describe their relationships, and then the weighted network was pruned. An optimization model of module division of crowdsourcing tasks under social design was established with the objective function of maximizing the degree of aggregation within the module, and minimizing the coupling degree between modules, and minimizing the difficulty of collaborative design, and an ant colony algorithm was used to solve it. The calculation methods of relevance of functional and structural information exchange among atomic design tasks and of the difficulty of contractor cooperation were discussed. The principles and steps of crowdsourcing task module division were given. Examples were given to illustrate the feasibility of the proposed method.
