模块化可以显着缩短交货时间并降低产品开发成本。现有的模块化研究大多集中在模块划分上,这只是集成模块化实现的初级阶段。随着模块数量的增加,产品设计工程师无法从已建立的模块组合中高效地获取满足新兴客户需求(CR)的模块,尤其是在复杂产品和系统(CoPS)开发中。 CoPS模块组合必须精心建立、规划和管理,为此提出了CoPS模块组合规划(MPP)框架,以帮助设计工程师在CoPS开发中获得最佳的模块组合。首先,CoPS 的 MPP 问题从两个角度建模为混合整数规划:每个参数模块的成本效用以及从 CR 映射的功能需求 (FR) 的信息内容。其次,分别基于部分价值模型和信息公理计算成本效用和信息内容。第三,采用启发式遗传算法(GA)来解决编程问题。最后,以大吨位履带式起重机(LTCC)MPP问题为例,阐述了该框架的有效性。
Modularisation can dramatically shorten the lead time and reduce the cost of the product development. Most of the existing modularisation researches focus on the module partition, which is just the initial stage of an integrated modularisation implementation. With the increasing of the module number, the product design engineers could not obtain the modules satisfying the emerging customer requirements (CRs) from the established module portfolio efficiently, especially in a complex product and system (CoPS) development. The CoPS module portfolio must be carefully established, planned and managed, for which a CoPS module portfolio planning (MPP) framework is proposed to assist the design engineers to obtain the optimal module portfolio in CoPS development. First, the MPP problem for CoPS is modelled as a mixed-integer programming from two perspectives: the cost utility of each parametric module and the information content for the function requirements (FRs) mapped from CRs. Second, the cost utility and the information content are calculated based on the part-worth model and the information axiom, respectively. Third, a heuristic genetic algorithm (GA) is employed to solve the programming. Finally, a large tonnage crawler crane (LTCC) MPP problem is performed as an example to elaborate the effectiveness of the proposed framework.
