【摘要】 对某超市的收银台排队系统进行了优化。以顾客能接受的最长排队队长及最长等待时间为约束,建立了多服务台负指数分布排队系统模型。通过对顾客一段时间内的到达数量、收银员对单个顾客的服务时间进行数据采集、以及对顾客进行相关问卷调查,得出计算机仿真所需的变量与参数,同时代入排队系统模型中进行数据分析与最优解确定,最终确定该超市最优的收银台数量。更多还原

【Abstract】 The cash register system of a supermarket is optimized. Depending on the largest queue length and the longest waiting time the customer can accept for constraints, a model of negative exponential distribution queuing system of multiple service checkouts is established. According to the collected data including the quantity of customers over a period of time, the service time of single customer and the related questionnaire survey, the variables and parameters for simulations are obtained. Then taking the processed data into the queue system model, the optimal solution can be determined. Ultimately, the optimal number of checkout can be determined in the vanguard supermarket.更多还原
