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,
( G: v/ }2 P5 w7 o 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.
3 B9 H. c: M" ^/ v5 G Loads are processed by each operator for the following time:
- A5 f% |! P+ p$ ? F Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
9 _, ^1 }7 Y8 D4 j5 O. J! E 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.$ I- Z6 ~- I1 w1 H
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.8 s4 q; V/ _9 g3 y
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.# S. q8 f* q/ _+ [# Z, N- i2 W
* }6 v: o( ?0 r* A- F问题:$ {* q* `3 Q) f; B
After running the model for 10,000 days, what was the average number of loads in each process?
