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,, e7 g, U/ }8 |
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.
; H" M/ C' A, ~3 R" j) k2 D& j- W4 V Loads are processed by each operator for the following time:. z. N1 s5 R4 e+ |3 W
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.3 F2 Z' I" C" K: L: l+ o9 V. h
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./ N4 m' D: X/ v
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.2 C) e% B/ T- [* k# m
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.7 O. H' j; n3 g

After running the model for 10,000 days, what was the average number of loads in each process?
