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 I4 V" D0 s! S. b 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.
: I- Z* m% q3 t! ^$ R' [9 g' | Loads are processed by each operator for the following time:# y6 ?( r% z' j" ?
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
+ l) s9 `5 V. a' Z0 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.5 y- W+ K3 ~) o4 G/ A; E, I& Z& r
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.7 h; }" n! c* ]- n T* S" x( [, U
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.5 a, u+ s9 H# f

问题:
( ?" B$ c+ {- u" wAfter running the model for 10,000 days, what was the average number of loads in each process?
