产品设计与工艺设计过程

产品设计与工艺设计过程是产品开发过程的核心,它包括与产品设计与工艺设计有关的所有技术活动和管理活动,代表了特定组织进行产品设计与工艺规划的行为,是特定组织为满足某一需求,利用各种资源、工具和方法进行的创造性活动,过程交付的内容包括产品设计与工艺设计相关文档和数据。产品设计与工艺设计过程本身是一个将工程技术、方法、工具和人员集成并付诸产品设计与工艺设计实践的技术和管理框架。目前,人们将注意力越来越多的集中在产品设计与工艺设计过程上,普遍认为,通过过程的设计、改进和有效管理而不是单单产品和服务的改进更能有效提高产品质量和服务质量,更能赢得时间。有学者提出产品设计开发中引入“过程工程”的概念,过程工程是指有关过程的定义、优化和控制等工程活动的总称。由此产品设计与工艺设计过程工程是指所有与产品设计与工艺设计过程建模、分析、实施、改进、维护以及与产品设计与工艺设计过程重组有关的工程活动。本文主要研究工作如下:研究产品设计与工艺设计过程多视图建模问题。建立了产品设计与工艺设计过程体系结构。通过分析产品设计与工艺设计过程特点,考虑过程描述上完备而又不冗余确定产品设计与工艺设计过程的W2H基本要素,指出产品设计与工艺设计过程主要解决做什么(What-任务)、怎么做(How-过程)、谁来做(Who-组织)问题。建立了基于W2H基本要素的三维空间模型。该模型具有三维可视化易理解、方便动态跟踪管理过程的特点。通过三维空间模型的截面和投影面明确给出模型各基本要素间的关系。从任务、组织、过程三方面跟踪监控产品设计与工艺设计过程进度,支持过程规划、分析、改进和管理。研究并行设计过程迭代(Iteration)问题,基于广义随机Petri网建立了产品并行设计过程模型,给出了基于工作流的过程抽象模型。分析了该工作流模型的组成模型。应用HPSim工具和Markov链方法对产品并行设计过程模型进行了性能分析并验证了其可靠性,分析模型运行特点。研究其基于工作流的产品并行设计过程动态运行控制问题,描述了产品并行设计过程中活动项状态及其转换以及活动项动作及其转换,给出了基于Petri网和任务驱动的并行设计过程工作流运行控制机制。研究产品并行设计过程活动重叠(Overlapping)问题。为规划设计与工

Product design and process plan process which include all the technique activities and management activities is the core of product development process. It’s the representation of Product design and Process plan behaves of certain organization. It a creative activity which carry out by certain organization with resources, tools and methods. The results of this process are Product design and process plan documents and data. Product design and process plan process is a practice process and a technology and management structure integrated with engineering technology, methods, tools and persons. Now, Product design and process plan process has been paid more and more attention. It is recognized to design, improve and manage the process is more helpful for the product quality and product time than to improve prove product and service. The concept Process Engineering has been imported in product development process. Process engineering composed with many activities includes process definition, process optimization and process control. So the Product design and process plan process engineering indicate all the activities such as process modeling, process analysis, process carrying out, process improving, process maintenance and process rebuilding. The research work done show as bellow:Study the multi-view modeling of Product design and process plan process. The system structure is built. Through analysis the process’s characteristic, the W2H model has been proposed as s main element to description process. We point out in this paper that the main problem need to be solved of Product design and process plan process is“Who”does“what”and“How”to do.3D spatial management model has been built Based on W2H model. It is a visual model which is easy to be understand and suitable for trace and management the process. Analysis the relation between the W2H model element though anglicizing the section and the projection of the 3D spatial model. The Product design and process plan process could be traced and watched from Task, organization and process. The 3D spatial model support process to be plan, analysis, improve, and manage.Study on the iteration in the concurrent design process. A Petri net based [url=] 更多[/url]
