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,! B k' A, R4 M$ a" b" E& K& `
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.
9 v3 Y8 e) W( r$ W Loads are processed by each operator for the following time:8 r( W* F/ d8 F3 f6 {
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
9 ~3 F/ O7 U) e" H" ?/ D& f 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.
; W' t5 _: F+ n7 W! y6 ~! b) ~7 w& } a Worker_C does the job in a uniformly distributed time between 30 and 90 mins.6 r0 r3 J- P8 f0 K" U' i
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.; H* C5 r) @; `: A5 `& m

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