设计主体的属性特征与设计任务间匹配程度是影响产品协同创新设计效率的重要因素。对设计主体进行属性特征分析、分类和对不同类型组合定量计算，在定义设计任务特征属性的基础上建立以产品协同创新设计总体持续时间最短为目标的效率模型，并设计基于PSO算法的模型求解方法。以某公司风机机舱的协同创新设计为例，验证了考虑主体属性及与任务匹配情况下的产品协同创新可缩短设计周期，提高设计效率。

The degrees that the design agent capacity matches the design task are an important factor affecting the efficiency of collaborative product innovation design. The classification and quantitative calculation of different types of design agent capacity combination is carried out after the characteristic of design agent is analyzed. An efficiency model whose goal is the shortest entire time is constructed based on the definition of task attribute,and then the solving method of efficiency model are designed based on particle swarm optimization algorithm. The collaborative product innovation design of cabin is taken as an example to prove that considering the matching agent attribute with task can shorten the design cycle and improve design efficiency.
