复杂产品研制项目的流程模块化分析方法

A Procedure Modularity Analysis Method of Complex Product Development Project

基于复杂产品研制项目模块划分不均匀、管理分工不协调的现状,首先从复杂产品研制项目流程的功能相关性和信息相关性两个方面,提出了项目流程的模块分解、分层及合并方法。其次,依据模块化程度函数和敏感度函数,分析项目流程的模块化程度和敏感度与特质模块间的变化规律,发现:模块化程度函数存在凹凸性拐点,模块化敏感度函数为凹函数。再次,以某航空复杂产品研制项目为例,通过对其模块化程度和敏感度曲线模拟,提出基于模块化程度及敏感度视角下,企业面对不同模块化程度和敏感度情况下的相应管理策略:当模块化程度较高且敏感度较低时,企业应考虑适当拓展新型研制业务;当模块化程度较低且敏感度较高时,应考虑增强企业管理柔性,适当减少新型业务开展力度。

Considering the complex product development project existing in non-homogeneity in module division and disharmony in management collaboration, a method of realizing the module decomposition by layer is proposed from the perspective of function relevance and information relevance. Then, according to the modular function and sensitivity function, the modularity degree and sensitivity characteristics of project procedures are analyzed. It is found that there exists an inflection point for the concavity of modularity function while the sensitivity function is concave. Moreover, an air project of complex product development is taken as an example and its procedure modules are decomposed. By simulating the modularity and sensitivity curves, corresponding management strategies of modularity are put forward from the modular degree and sensitivity perspective： When the modular degree is high, and the modular sensitivity is low, the company should expand the new development business. Otherwise, the company should improve the management flexibility and reduce the scope of new business.
