基于CPN Tools的“多种权限+操作队列”并发冲突控制方法研究
|
摘要
为解决"操作权限+时间戳"并发控制法中存在的不能发挥每名维修人员作用的问题,提出了"多种权限+操作队列"并发控制方法,讨论了该方法重要功能模块的工作原理,给出了方法运行过程的流程图,及着色Petri网图。利用CPNTools对整个流程进行过程仿真。得到的仿真数据表明,该方法可以保证低权限维修人员的操作公平性,以使每名维修人员的作用得到充分发挥。
There are problems with concurrent control methods such as operation rights + timestamp, for example, the role of each maintenance worker cannot be played. The concurrent control method of multiple rights and operation queues can solve this problem. The working principles of the important function modules of this method are discussed, and the operation method of the process flow chart and colored Petri net is given. The data are simulated by the CPN Tools for the entire process. Simulation results show that this method can ensure the operation fairness of the low maintenance personnel, and make every maintenance staff play their full role.
