本文把电铲—汽车装运系统看成服务时间为爱尔朗分布的有限、循环排队系统,建立了汽车在排卸点不出现排队现象情况下的装运系统的数学模型,编制了求解该模型的计算程序,并通过实例来说明如何确定最优的车铲比及装运系统的生产能力。
In this paper, the shovel-car shipping system is regarded as a limited and cyclic queuing system with the service time distributed by Erlang. The mathematical model of the shipping system is established when the car does not appear queuing at the discharging point. Calculate the program, and through examples to illustrate how to determine the optimal car shovel ratio and shipping system production capacity.
