基于DSM的复杂研发项目价值流优化

针对传统设计结构矩阵(DSM)优化研发项目的不足,本文采用基于价值要素的DSM价值流优化方法,提出了活动的"费用时间比"参数和返工因子DSM矩阵,以综合反映活动的费用、时间及返工风险等价值要素对复杂研发项目活动排序优化的影响。进一步,将活动的"费用时间比"参数和返工因子作为优化参数,构建了相应的DSM价值流优化目标函数。对某案例优化计算表明,与传统方法相比,采用本文提出的价值流优化方法能明显降低由于返工而引起的项目费用增加值。

Value Stream Optimization for the Complex R&D Project Based on DSM

To solve the shortcoming of traditional Design Structure Matrix(DSM) optimization for R&D project,this paper presents the approach of DSM value stream optimization based on value factor.The activity’s ratio of Cost to Time(CTR) and Rework Factor DSM are proposed to reflect synthetically the infulence of value factors including the activity cost,time and rework risk for sequencing optimization of the complex R&D project.Furthermore,the optimization objective function is built based on CTR rework factor as optimization parameters.Finally,for a typical case optimization minimizing the value stream optimization objective function,the result indicates that the feedbacks and the total project cost can be reduced significantly compared to traditional DSM optimization objective.
