研究规定服务标准下车间流程的能力可获性服务模型,根据流程在服务调度时,车间服务点处于三种状态,采用三态系统来计算网点特定服务质量事件的概率。建立多队列服务调度模型,按照M/M/m/m/FCFS服务模式计算网点服务可获性概率。按照流程事件发生的条件概率,求得在小于T时间内该调度模式下流程能力服务可获性公式,讨论流程服务能力可获性改进途径。
According to the process of service scheduling, the workshop service points are in three states, and the three-state system is used to calculate the probability of network-specific quality of service events. Establish multi-queue service scheduling model and calculate the service availability probability of network service according to M / M / m / m / FCFS service mode. According to the conditional probability of the occurrence of the process event, the formula for obtaining the service capability of the process capability under the scheduling mode in less than T time is obtained, and the improvement of the availability of the service capability of the process is discussed.
