基于多智能体的虚拟企业群协同生产调度模式研究

为了实现虚拟企业群的协同生产调度, 提高企业群整体运作水平, 建立了基于多智能体的虚拟企业群制造企业生产调度模型, 分析了生产计划调度及信息交互作用。在企业协同层, 提出了基于多目标和价格协商的供应商选择过程, 确定了合作伙伴的初选过程方法, 企业层采用了基于EDD+SCR规则组合确定企业任务分配, 并为所有订单任务确定交货期, 各车间层则根据企业层的生产计划进行车间生产调度安排。最后, 运用Swarm仿真软件平台对案例进行仿真分析, 验证了提出的生产调度模式可以有效提高各企业的车间负载率, 并使车间负载率在短时间内达到稳定状态, 从而合理有效地利用企业资源。

Model of collaborative production scheduling in virtual enterprise cluster based on multi-agent systems

In order to realize collaborative production scheduling in virtual enterprise cluster, raise its operation ability, this paper established a production model on the multi-agent for virtual enterprise cluster manufacture enterprises, meanwhile detailedly analyzed productive plan scheduling and information dispatch. This paper proposed the selection process based on the multi-agents and the price consultation supplier in enterprise coordination layer, especially emphasized the partner primary election process. Based on the EDD+SCR rule combination, it determined enterprise objective assignment, and definited all order form with date of delivery. Every workshop layer carried on the workshop production scheduling arrangement according to the enterprise layer productive plan. Finally, the case simulation was carried by using the Swarm simulation software platform. The analysis simulation result views that supplies chain coordination production scheduling is possible to effectively enhance the enterprise workshop load factor, and enables the workshop load factor to keep the steady state in a short time. The resource of the virtual enterprise cluster is used rationally and effectively.
