摘要
针对产品设计约束具有层次性、分布性及动态性的特点,用分布式约束满足问题模型难以进行产品设计冲突消解的问题。将产品设计转化为商空间粒度世界,建立了分层递阶粒计算产品设计冲突消解模型。对产品设计问题进行粒化和划分,通过商映射和粒度合成实现不同层次之间以及不同设计领域之间的映射和回溯,采用分层次、逐步细化的粒计算方法进行冲突消解。这种由粗到细、层层深入、逐层求解的粒计算消解方法简化了分布式动态约束满足问题,降低了问题求解的计算复杂性,具有系统性、整体性和层次性特点。
The conflicts of product design are difficult to be resolved using the model of distributed constraint satisfaction problem for the characteristics of hierarchy,distribution and dynamic of product design's constraints.Product design is translated into a granular world in quotient space,and a multi-level hierarchical model of granular computing for conflict resolution in product design is constructed.The conflicts of product design can be resolved hierarchically and progressively through granulation and division of product design's constraints and combination between quotient mapping and granularity synthesis which can achieve the mapping and backdate between different design domains.The method resolves the problem in a hierarchical coarse-to-fine and layer by layer manner.By the granular computing for conflict resolution,the distributed constraint satisfaction problems can be simplified and the computing complexity of the problem solving can be decreased,and it has the characteristics of systematicity,integrity and hierarchy.
