刚刚开始学auto mod,这道题目搞不明白,希望大家看看 题目是这样的,2 F% L( P. R0 w; M: w
Create a new model containing three independent processes, each with one operator. In each process, loads first move into an infinite capacity waiting queue, then into a single-capacity processing queue.$ b9 t' U, F4 B1 O! L" |/ h
Loads are processed by each operator for the following time:, }5 O" Y5 i! x' }5 @4 u
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
; H* f) c) J, a8 K/ W5 J Worker_B does the job according to a triangular distribution with a min of 30 mins, most likely value of 60 mins, and a max of 90 mins.6 E9 }& H0 g" T3 }6 J
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.% t1 I/ W6 X. J
Send loads to each pocess at the same rate (an exponentially distributed inter-arrival time with a mean of 68 mins) to understand the difference in the processing times of the three workers.

问题:
