【摘要】 随着先进制造技术的研究与应用的不断深入，并行工程的哲理是现代先进制造技术的核心之一，它对产品设计制造过程中的信息集成提出了更高的要求。本文就并行工程环境下CAPP系统的面向对象建模、统一的信息模型、工艺路线的实例推理、产品可制造性评价模型以及CAPP系统与PPS集成等方面的关键技术进行了研究，主要内容包括： 1．在分析传统的结构化软件工程和面向对象的软件工程的基础上，详细的介绍了统一建模语言（Unified Modeling Language，简称UML）。针对复杂的软件系统提出了一种详尽的软件的开发过程—迭代增量式开发过程，该过程是一个迭代增量式的开发过程。 2．系统地建立了CAPP系统中涉及的信息模型，包括产品特征模型、制造资源模型、工艺过程模型以及生产数据模型并提出了面向CAD/CAPP/PPS集成的统一数据模型（Unified Data Model，UDM）。 3．从实例的应用记录、基于神经网络的实例动态分类、工艺路线规划实例神经索引和工艺路线规划实例推理等方面，讨论了基于神经网络的工艺路线规划实例推理。 4．应用模糊技术从产品可制造性模糊综合评价方法以及产品可制造性功能结构等方面对产品可制造性评价进行探讨，同时针对CAPP与PPS的集成问题，研究了CAPP和PPS的多级并行分布式集成的方法、模型。更多还原

【Abstract】 With the further research and application of advanced manufacturing technology, the philosophy of Concurrent Engineering (CE), as the core of modem Advanced Manufacturing Technology, gives more high requirements with product development. This dissertation mainly researched the key techniques of CAPP in the CE environment, includes orient-object modeling, unified information model, case-based process route planning, product manufacturability evaluation model and integration of CAPP and PPS, as following: 1. Under the base of analyzing structurized software engineering and orient-object software engineering, it introduced Unified Modeling Language (UML). And it gave a iterative-increment software development process. Using this software development process should reduce the risk of project. 2. The information model of CAPP includes feature product model, manufacturing resource model, process plan model and product manufacturability model. Under the base of analyzing the information model, it gave Unified Data Model (UDM). With it, CAPP can realize concurrent decision-making with CAD and PPS in CE environment. 3. A methodology of case-based process planning, based on neural networks, is presented. This approach makes use of neural network to realize the dynamic classification and to index these cases, and makes use of the learning and self-organization of neural networks to reduce periodic human maintenance of the CBR system. 4. The fuzzy mathematics approach is applied to evaluate product manufacturability. And in the same time, studied the multi-level distributed approach and model for integration of CAPP and PPS.更多还原
