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 r3 \% H/ V1 [2 j8 N" C 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.
3 X. A& ?, C4 t8 M M8 J Loads are processed by each operator for the following time:
' W- R" ]; r/ V" U( i Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
0 G/ q$ j a1 ~/ d0 V: B N' r1 ? 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.% O7 R5 A ^6 o, B- H
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
, ^2 `" P7 k7 m/ q3 `6 @5 d2 NSend 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; o) X( K& M" ]- ?9 U# d

问题:" K4 s8 i* @' }" p1 S3 i& M
After running the model for 10,000 days, what was the average number of loads in each process?& K% E! T& {1 M9 G' I
