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,/ ?; o; Z& C( u# q
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.$ C; p) v9 k+ E) A3 |# W0 n; K
Loads are processed by each operator for the following time:! T% j% h( S! a4 o8 c- D3 Q, i
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins. I& J( w" t" P X5 p3 `+ q' P
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.
0 Y( ~5 u: h1 \4 Q& E6 e Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
6 S$ v2 N1 R, f0 A, w3 u9 {/ |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.% P% r9 D+ @7 w0 \- L' D

问题:& l! `$ Q( _& o2 O0 a
After running the model for 10,000 days, what was the average number of loads in each process?
