面向生产计划分析的协同制造过程建模语言及建模仿真系统

Collaborative manufacturing across enterprises involves many types of elements,complex linkage relations and large internal and external uncertainties,which leads to weak collaborative operation ability.In view of the weak top-level management ability and the lack of effective planning analysis methods for collaborative manufacturing,a collaborative manufacturing process modeling language for production plan analysis was proposed,which provided a domain abstract modeling and model simulation tool for decision level.To define the language,the domain knowledge of collaborative manufacturing was summarized,and a conceptual model was developed.Based on the model,a collaborative manufacturing process modeling language Collaborative Manufacture oriented Process Modeling Language (CoM-PML) was defined.A modeling and simulation system based on CoM-PML named Process Optimization Modeling Enterprise System for Collaborative Manufacturing (POMES4CM) was developed to assist decision level to analyze the complete product cycle and resource utilization rateby executing multi-process simulation.The collaborative manufacturing process of three complex products was selected for case validation,the process model and production plan with guiding significance were obtained,which verified the effectiveness of the method and system.
