Abstract:

For solving the coordination problems of tasks and resources in dynamic manufacturing environments, the optimization process of the coordination problems among tasks and resources was analyzed, and a mathematical model was established. Inspired by the endocrine regulation principle, two kinds of hormone（task hormone and resource hormone）were designed. Considering the influences of the emergency in manufacturing system, a novel dynamic coordination approach was proposed based on the hormone regulation principle. This proposed approach was characterized by higher efficiency, lower communication, and better robustness. A prototype system was developed, and experimental results confirm that the approach has excellent stability and optimization ability for task allocation problems in a static environment, and it also has excellent control performance and adaptability to disturbances in shop floor.

Key words: manufacturing system, task and resource, endocrine regular mechanism, dynamic coordination

摘要：

针对制造系统在动态环境下的任务与资源协调优化问题，在保证按时完工的前提下，分析了制造任务与资源协调优化过程，建立了数学模型。受人体内分泌调节机制的启发，设计了两种可以相互影响的激素(任务相关激素和资源相关激素)，同时，考虑到突发事件对制造系统工作性能的影响，提出了基于激素的资源与任务的动态协调算法。实例验证表明，该算法切实可行，具有任务分配质量高、动态协调性能好、协调过程通信量小、控制系统鲁棒性较好等优点。
