Simulation study for reliability in uranium mine transportation and elevation system based on Stateflow

运输与提升系统是地下铀矿山生产大系统中的重要子系统,研究运提系统可靠性对合理安排维修周期、节省企业成本、提高产量具有重要意义。针对传统可靠性方法在复杂可修系统可靠性分析中的局限,提出了基于Stateflow的运提系统可靠性仿真方法。为了更加符合实际,模型中将运提系统作为柔性系统处理,并认为维修资源有限。最后用模型对一实例进行分析,仿真结果表明,基于Stateflow的仿真分析方法能够有效评估运提系统的可靠性参数。

Transportation and elevation system is a very important subsystem in the uranium mine production system.Therefore,it is important to study its reliability for arranging maintenance cycle,saving enterprise costs and raising production.In order to overcome the limitation of traditional reliability method,this paper presented a simulation method for reliability in uranium mine transportation and elevation system which is based on Stateflow.To accord with actual,the transportation and elevation system was taken as flexible system,and the maintenance resource is thought to be limited.Based on it,a case is studied using the simulation model.The results show that the simulation method can efficiently evaluate parameters of reliability in transportation and elevation system.
