Integrated scheduling which aims at processing and assembling of single-piece complex product being processed simultaneously is proposed after processing scheduling and assembling scheduling. When production resources for single product with tree structure are distance distribution, collaborative computing of distributed manufacturing system based on integrated scheduling needs to be researched, whose research includes how to decompose complex product according to the characteristics of the resources and position, and how to take effective communication and transportation plan to make distributed resources coordination treatment and realize products manufacturing with low cost and high efficiency. This project is not only an innovative applied basic research, and fits the current demands for product diversification and the national conditions which is important resources uneven distribution. Though the collaborative computing of distributed manufacturing system is huge multifarious, the point is how distributed production resources can work effectively and collaboratively. So the plan for this project is to research: 1. the relationship between integrated scheduling of distributed manufacturing system and collaborative computing; 2. doing collaborative computing with decomposing single-piece according to The characteristics of distributed resources; 3. the integrated scheduling plan for the processing and assembling of product components; 4. doing collaborative computing for choosing place of assembling according to the complete time of product components, assembling constraint condition, transportation condition and so on; 5. realize distributed manufacturing system for single-piece complex product based on integrated scheduling with collaborative computing capacity through researching information transfer and feedback mechanism.
综合调度是继加工调度和装配调度之后新提出的针对单件复杂产品加工和装配一同处理的调度方法。当树状结构单产品的生产资源远距离分布时,如何根据资源的特点和位置分解复杂产品,如何采取有效的通信和运输,使分布式的资源协同处理,实现低成本高效率的产品制造,需要进行基于综合调度的分布式制造系统协同计算的研究。该项目不仅是创新的应用基础研究,而且符合当前对产品多样化需求和重要资源分布不均衡的国情。虽然基于综合调度的分布式制造系统庞大繁杂,但其重点是分布式生产资源如何协同高效工作,因此本项目拟研究:1.分布式制造系统综合调度与协同计算的关系;2.根据分布式资源的特点,进行单产品部件分解的协同计算;3.产品部件制造和组装的综合调度方案;4.根据产品部件完成时间、组装约束和物流等条件,进行组装地点选择的协同计算;5.研究信息传递和反馈机制,实现具有协同计算能力的基于综合调度的单件复杂产品分布式制造系统。
