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,4 B" m$ A; N" x3 u9 s- Z% V7 w
  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.2 A5 Y1 f; l- x3 v
  Loads are processed by each operator for the following time:
' u! J$ C% \$ U' ?# @  K  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.5 F  T8 ^# W0 j
  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.
& E# ?% ~! L7 i* R5 {8 x( p3 d( t  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
3 P7 O, k4 B# X2 D/ }7 g) MSend 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.! ~4 d- s6 X( @$ t" D1 Q
" F1 ?) H' j) q, F# r7 T9 v
问题:- ?. W+ I7 Z. ~/ F% T( T% H0 d
After running the model for 10,000 days, what was the average number of loads in each process?
