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,* ^5 X- W6 h) Z# y
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 M$ k9 W9 \7 R1 ], f
Loads are processed by each operator for the following time:
' j- W! e( \6 R o( \0 d# e2 B/ g Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.$ G) q- m* Q& `
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.- m% f k! E/ p$ B
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
/ X0 p4 Y5 _: |/ \& wSend 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.1 U/ l9 [( U2 ?9 {+ p( E* C, f

After running the model for 10,000 days, what was the average number of loads in each process?1 M- g4 w F4 c' I& x0 `# q) `
