依赖结构矩阵(DSM)能够清晰地描述和分析产品开发过程中大量出现的迭代问题,并可以对工序进行排序优化,以减少迭代,从而加快项目进度,节约成本。首先对产品开发项目的特点做了介绍,指出传统项目管理工具在处理此类问题上的不足。然后对DSM理论做了概述,并提出了一种基于解耦的DSM流程优化算法。最后指出排序优化时除了考虑最小化反馈标记个数,还应当考虑工序的费用、时间等因素。 Dependency Structure Matrix (DSM) can clearly describe and analyze iterative problems that arise in the product development process, and can optimize and optimize the process to reduce iteration, so as to speed up the project schedule and reduce costs. Firstly, it introduced the characteristics of product development project, and pointed out the deficiency of traditional project management tools in dealing with such problems. Then the DSM theory is summarized and a decoupled DSM process optimization algorithm is proposed. Finally, it points out that in addition to minimizing the number of feedback markings, sorting and optimization should also consider factors such as process cost and time.
