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,, T6 ~8 `: G# {9 H, R% I; n3 d, C) N
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.# g- N4 X0 B" ?1 l. s) U A
Loads are processed by each operator for the following time:
0 m) F5 ]! ?5 W. a) x Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
. o2 f7 j( o0 u" M9 z- Y1 G 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.! l) f" n9 o9 ~( a1 N
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.( P' h4 |' q) L4 ~+ H w3 P
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.2 c2 ]6 V; ^; T& Y/ D

After running the model for 10,000 days, what was the average number of loads in each process?# }& l* K* ~$ s2 x1 b, H
