【摘要】：复杂产品在组成、管理以及工作环境等方面都比较复杂，涉及多个领域、多门学科以及多种技术的运用，其研制过程覆盖整个生命周期，同时强调空间上的异地协同。为便于复杂产品项目的执行与管理，运用工作分解结构对其进行逐层分解，但是分解后的任务之间关系错综复杂，阻碍对项目进度进行有效控制。复杂产品项目在研制过程中由多个参与者协作完成，，由于参与者在项目组织中的层次不同，从而对进度控制流程的需求存在差异，因此如何对复杂产品项目进行有效控制，同时构建不同层次的控制流程需求则成为研究的重点。进度控制是项目按时按质完成的重要保障，运用工作分解结构将复杂产品项目进行逐层分解，拆分为相对简单的任务集群，方便多项任务同时执行，从而可以缩短项目工期；对分解后的任务之间的耦合关系，则需要运用模糊依赖结构矩阵对任务之间的耦合关系进行分析，达到消除或者降低耦合关系的目的；之后可以运用责任分配矩阵将任务集群分配到不同的部门或者协作企业，明确任务的责任者，防止任务责任者之间角色的混淆。因此本文从分析任务之间的耦合关系出发，研究项目进度控制问题。本文的研究内容包括以下几方面：（1）对协作环境下的复杂产品项目进度控制需求进行分析：首先分析复杂产品项目工作分解的特点以及存在的问题；其次，阐述协作环境下的复杂产品项目进度控制的特点；进而总结协作环境下的复杂产品项目进度控制的影响因素与方法；最后，从实时性、规范性以及集成控制三方面阐述协作环境下的复杂产品项目进度控制需求；（2）复杂产品项目工作分解后的解耦研究：首先分析复杂产品项目进行工作分解后的任务之间的关系；其次，构建模糊依赖结构矩阵描述任务之间的关系以及依赖关系的强弱程度；最后，运用矩阵乘方法确定耦合任务集，消除或者降低任务之间的耦合关系，达到对耦合任务进行规划的目的；（3）协作环境下的复杂产品项目进度控制流程：首先对复杂产品项目工作分解后的任务工期进行估算，为项目进度控制奠定基础；其次，阐述协作环境下的复杂产品项目进度控制的原则与类型；然后总结协作环境下的复杂产品项目进度控制流程；最后，基于遗传算法对进度控制进行研究。
[Abstract]:Complex products are complex in terms of composition, management and working environment. They involve many fields, disciplines and the application of many technologies, and their development process covers the entire life cycle. In order to facilitate the execution and management of complex product projects, the task decomposition structure is used to decompose it layer by layer, but the relationship between the tasks after decomposition is complicated. The complex product project is completed by the cooperation of multiple participants in the development process. Because of the different levels of participants in the project organization, there are differences in the requirements of the schedule control process. Therefore, how to effectively control complex product projects and build different levels of control process requirements has become the focus of research. Schedule control is an important guarantee to complete the project on time and according to the quality. The complex product project is decomposed layer by layer by using the work decomposition structure, which is divided into relatively simple task cluster, which facilitates the execution of multiple tasks at the same time, so that the project duration can be shortened. In order to eliminate or reduce the coupling relationship between tasks, it is necessary to analyze the coupling relationship between tasks by using fuzzy dependency structure matrix. Then the task cluster can be assigned to different departments or cooperative enterprises by using the responsibility assignment matrix to clarify the responsible person of the task and prevent the confusion of roles between the task responders. So this paper starts with the analysis of the coupling relationship between the tasks. Research project schedule control problem. The research content of this paper includes the following aspects:. Firstly, the paper analyzes the characteristics and problems of complex product project schedule control under collaborative environment, secondly, expounds the characteristics of complex product project schedule control under collaborative environment. The main contents of this paper are as follows: (1) analyzing the characteristics of complex product project schedule control under collaborative environment: firstly, analyzing the characteristics of complex product project work decomposition and existing problems; Then summarizes the influence factors and methods of the complex product project schedule control under the cooperation environment, finally, expounds the complex product project schedule control demand under the cooperation environment from the real-time, the standard and the integration control three aspects; (2) the decoupling research of complex product project after work decomposition: firstly, the relationship between the task after work decomposition of complex product project is analyzed; secondly, The fuzzy dependency structure matrix is constructed to describe the relationship between tasks and the degree of dependence. Finally, the matrix multiplication method is used to determine the coupled task set to eliminate or reduce the coupling relationship between tasks. To achieve the purpose of planning coupling tasks; 3) the progress control flow of complex product project under collaborative environment: firstly, the task duration after work decomposition of complex product project is estimated to lay the foundation for project schedule control; secondly, This paper expounds the principles and types of complex product project schedule control in collaborative environment; then summarizes the process of complex product project schedule control under collaborative environment; finally, studies progress control based on genetic algorithm.
