【摘要】 企业在产品开发过程中优化各种设计信息和资源,协调与客户及协作企业等之间的关系,已成为一种产品开发的重要模式。产品协同开发链为这种开发模式提供了一个有效方法和手段。面向项目构建跨企业产品协同开发链,基于成员间的资源规划和优化配置进行产品协同开发,从而及时准确的响应细分市场的需求。因而,产品协同开发链的组织、构建、优化、协调以及重构等内容是研究的重点和方向。协同开发资源的统一描述和管理是协同开发链进行规划和实施的基础。基于协同开发链资源的特点,提出了由应用模型维、生命周期维、资源分类维等组成的三维建模体系结构。为保证协同开发链资源信息数据的一致性,将资源按照其共同属性和特征进行了细化分类。并基于开发链三维建模体系和资源分类信息的研究,构建了协同开发链资源信息逻辑结构模型。零部件和供应商管理旨在实现对零部件和供应商资源的有效利用。首先对供应商关系进行了分析,从而为企业不同的供应商管理策略提供依据。结合产品协同开发链生命周期四个不同阶段的各自特点,提出并分析了相应的供应商管理事件处理流程。同时,对实现零部件和供应商管理的资源检索、安全管理技术等等关键技术进行了表达与分析。为保证跨企业复杂产品协同开发过程的顺利进行,需通过任务分解和分配实现子任务和供应商的有效匹配。通过对跨企业产品协同开发任务分解过程的分析,提出了相应的任务分解原则。利用模糊匹配法考查供应商关于新产品的设计和制造能力,判断任务分解的可行性;同时引入任务间影响度和响应度概念考查子任务间交互与影响,最终将任务分解为相对独立的子任务集合。基于分解得到的设计任务集合以及待选供应商集合,将供应商产品质量、成本等任务分配影响因素和供应商信息及其资源利用状况等供应商影响因素相结合,建立设计对象的分配优化模型。综合考虑任务分配的影响因素,基于提出的任务分配策略和分配原则,选择跨企业产品协同开发链中的最优供应商。最后基于ASP、SQL开发了产品协同开发链集成管理系统网络平台,实现客户需求管理、产品平台管理、供应商资源管理、任务分解分配、供应商选择和责效评估等的导航。本文主要对跨企业模式下的零部件和供应商管理子系统、任务分解分配子系统进行了开发。零部件和供应商管理系统基于产品协同开发不同阶段提供了不同的零部件和供应商事件处理功能。任务分解和分配子系统提供了复杂产品分解和相应子任务分配等功能,为实现任务和最优供应商的一一对应提供了操作平台。更多还原

【Abstract】 In the process of product development, the optimization of various design information and resources, and the coordination between manufacturer, customers and suppliers are widely applied as an important development mode. PCDC (Product Collaborative Development Chains) provides an effective method for this new development mode. Project-based PCDC is constructed to response the subdivision market demand through resource planning and optimum allocation of inter-enterprises. Therefore, how to organize, construct, optimize, coordinate and reconstruct the PCDC are the core research interests.The uniform description and management of collaborative development resource is the foundation of PCDC planning and implementation. So based on characteristics of collaborative development resource, a three-dimensional modeling structure is proposed and analyzed, including application module, life-cycle and resources classification dimensions. For the data consistency in collaborative development chains, PCDC resources are classified in terms of their property and character. And the logic structure model of PCDC resource information is also proposed.The main purpose of the components and suppliers management is to realize the effective utilization of the component and supplier resources. First, the relation among the suppliers is analyzed, which provides the basis for the different strategy of the suppliers’ management. Second, according to the characteristics in the four different phases of PCDC life cycle, the corresponding processing flow of the suppliers’ management events is also discussed. And the key technologies, such as resource search and security management for the management of the components and suppliers, are expressed and analyzed as follows.In order to make process of inter-enterprises complex product collaborative development go well, the effective matching between subtasks and suppliers should be realized by task decomposition and allocation. The process of task decomposition is analyzed and the relevant principles are proposed. The new product’s design and manufacturing capacities of suppliers are measured and the feasibility of task decomposition is estimated using a proposed fuzzy matching methodology. The interaction and influence between sub-tasks are examined using the concept of influence and responsibility degree, at last, the task is decomposed into the independent sub-tasks set. Based on the collections of design sub-tasks and candidate suppliers, the impact factors such as product quality and cost etc. and the information and resource utility of supplier are considered synthetically, the optimal allocation model of design object are established. Based on the proposed task allocation strategy and principle, the corresponding algorithm is used for selecting proper designer or supplier for product development collaborative chain.Finally, based on ASP, SQL, the network platform of integrated management system for PCDC is proposed. In this paper, component and supplier management subsystem and task decomposition and allocation subsystem are designed. For component and supplier management subsystem, it has the function of component and supplier event processing on different stages of PCDC. And task decomposition and allocation subsystem can support complex product decomposition and corresponding subtask allocation function, as the operation platform of one-to-one correspondence between task and optimized suppliers.更多还原
