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,3 \! v7 T' Q& C" ]/ m0 `& i2 C
  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.6 l* a2 a4 O$ ^$ K+ {
  Loads are processed by each operator for the following time:
3 b+ w9 |! y( t8 y7 u. B/ N4 w  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.; D& r5 n8 P" d. _$ L
  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.
1 `; ^$ d) O8 [4 Y2 K  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.! k7 b3 P) s( c
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 N  e5 P- I% x5 v8 @! J* ]
. @6 P% `6 Q5 S; D' ~/ V
问题:4 v7 F6 }7 l/ W4 w7 I8 ^2 c; V. @
After running the model for 10,000 days, what was the average number of loads in each process?
