2.单窗口串联排队系统的模拟

(1)题目

某汽车加油站只有一台加油器，加油的汽车到达间隔时间为均匀分布，均值为100秒，

方差为10秒。到达加油站后先排队等候，再加油，加油服务时间也为均匀分布，均值为80

秒，方差为8秒。加油后司机要去交费窗口排队交费，交费时间也为均匀分布，均值为50

秒，方差为30秒。求解：（1）加油站与交费窗口的利用率；（2）加油与交费的平均等候时间。

(1)题目

若加工后的零件放在传输带上运输,零件到达第一个检查员及每个检查员之间需要输送

2分钟，通过模拟分析每个检查员的工作情况，有多少个零件在通过第3个检查员后仍然检

查不到？图4.6是这一系统的示意图，卜面给出程序清单及运行结果。

(4)题目答案

关于3个检查员的工作情况可以从关于设施的模拟结果报告中看到：1号检查员利用

率为83.3%,2号检查员利用率为72.9%,3号检查员利用率为52.5机虽然有125个零件没

有受到检查，但是第3号检查员的利用率仅为52.5%,其中一个原因可能是由于设置了运行

时间为2分钟所致。

(5)改进：可以延长零件到达每个检查员的时间，将2分钟改为5分钟。
