基于协作元的产品协同设计研究

设计任务的组织、优化及动态控制都是产品协同设计的关键问题。引入了以设计人、个人协同代理、设计工具为内容的“协作元”概念。以个人协同代理和任务公告模板为基础 ,通过招投标模型实现产品设计任务的合理配置 ,并提出关键路径法控制产品设计周期。工程实例表明 ,所提方法合理有效 ,设计任务的组织、分解、配置、控制有了明显的理论依据 ,对产品协同设计水平有明显的提高作用

PRODUCT COOPERATIVE DESIGN BASED ON COLLABORATION CELL

The organization,optimization and dynamical control of design assignments are key issues of product cooperative design. Existing methods for product cooperative design focus on the disposing of business process. They do not take into account the optimum way of distributing subtasks in design. An idea of "collaboration cell"is presented which is made up of designer, personnel cooperative agent(PCAgent)and design tools. A model of invitation and bid is put forward to reasonably deploy subtasks in product design based on PCAgent and task bulletin board, with the decision-making bid in PCAgent and the definition of Ability operator, Famine operator and Importance operator. The"key path"method is also presented to control and optimize the period of design, which can inspect whether the task is reasonably distributed into subtasks or not. The experiment in engineering indicates the rationality and validity of all methods which provide the dearly theoretical foundation for the organization,optimization,deployment and control of all design assignments, and obviously improve the product cooperative design.
