代码说明:

说明:  对于顾客成批到达、成批服务排队系统,给定输入参数: ? ? , , λ ?(都为正数),随 机生成顾客到达的间隔时间,一批顾客中的数量,一批顾客的服务时间;成批服务的顾客数 c (为正整数);初始时刻,系统中人数为 0;系统运行时间 T (比较大,使得系统稳定), 按照前述规则模拟系统运行。回答: (1) 参数 ? ? , , λ 如何取值,才能保证系统排队人数不会趋于无穷,即系统稳定; (2) 参数 λ 的灵敏度分析,即固定 ? ? , 且 λ 取不同值(如 5 个,参数组合保证系 统稳定)时,五个排队指标如何变化。一个指标的变化趋势画一个子图,每个 子图需要加标题注明,五个指标共 5 个子图画在一张大图上; (3) 参数 ? 的灵敏度分析,要求同(2); (4) 参数 ? 的灵敏度分析,要求同(2); (5) 参数 c 的灵敏度分析,要求同(2)。(For the queuing system of customers arriving in batches and serving in batches, the input parameters are given as follows: The interval between arrivals of machine generated customers, the number of customers in a batch, the service time of a batch of customers; the number of customers serving in batches C (positive integer); initial time, the number of people in the system is 0; system running time T (relatively large, making the system stable).)
