摘要

网络化制造资源集成共享与优化配置主要包括协同制造总任务的分解、单任务驱动的制造资源的评价选择、时序约束关联单任务链驱动制造资源链的构建三个阶段。首先根据协同制造总任务分解的特点,提出了跨组织协同制造任务分解过程模型和相应的分解算法。然后提出了单任务约束驱动网络化制造资源评价指标体系与评价算法,在此基础上对单任务驱动检索的候选资源集,提出了基于改进蚁群算法的时序约束关联单任务链驱动网络化制造资源服务链构建模型与算法。最后通过仿真算例说明了研究成果的有效性。%The nature of networked manufacturing resource integration and optimized configuration is a complex process.In this process,total collaborative manufacturing tasks can be decomposed to construct a single-task-driven chain according to time and sequence constraints in cross-organizational.The process mainly included three stages：the decomposition of the collaborative manufacturing tasks;the evaluation and selection of the manufacturing resources and the construction of the single-task-driven manufacturing resource chain.Firstly,according to the features of the collaborative task decomposition,a process model for cross-organizational collaborative manufacturing and corresponding decomposition algorithm were proposed.Secondly it also put forward an index system and evaluation algorithm for the networked manufacturing resources evaluation.Then the networked manufacturing resource service chain model and the algorithm which was based on improved ant colony algorithm with single task-driven related timing constrains were proposed.Finally,a simulation was taken to verify the feasibility of this research.
