中文摘要：

为分析复杂研发项目的功能、产品和流程之间的耦合依赖关系,本文基于设计结构矩阵（DSM）和质量功能展开（QFD）等结构化方法,提出了逐级分析研发项目中元素之间依赖关系的多级瀑布模型。首先,构建QFD中功能需求与设计参数之间的关系矩阵,以分析顾客的功能变更对相关设计参数及产品和流程的影响,提出了量化功能DSM中元素之间依赖关系的模型。进一步,采用多领域矩阵（MDM）构建由已知领域DSM推导未知领域DSM的模型,提出了由功能DSM推导产品DSM及由产品DSM推导流程DSM的转换模型。最后,对初始的流程DSM进行了排序优化和仿真分析。

英文摘要：

In order to analyze the coupling dependency relationship among functions, products and processes in complex R＆D projects, this paper proposes a multi-level waterfall model to analyze dependency in R＆D projects based on Design Structure Matrix （DSM） and Quality Function Development （QFD）. Firstly, we build a QFD matrix representing the relationship between functional requirements and design parameters for quantifying the influence of function modification on design parameters, product and process. And a model of meas- uring dependency strengths in the function DSM is presented. Secondly, the model deducing a derived DSM matrix from a known DSM is built based on Multi-Domain Matrix （MDM） , for example, from function DSM to product DSM, and from product DSM to process DSM. Finally, sequence optimization and simulation are conducted to the original process DSM.
