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,, i- e" K. O! a0 }
  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 c7 A8 p% m% G1 u! P
  Loads are processed by each operator for the following time:
# M- j. V- |! p  @  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.6 v+ ^$ A% l9 V. s" w2 m
  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.: ^/ b4 p; J- [  I; y% I$ R' o, N
  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
# B+ n5 N: h9 c) f( s1 ~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.0 a' r  C9 G2 {/ y& N0 k. i

: w; f3 U( t9 N- v$ z5 D问题:% Q! \0 j1 |$ ]. A( r
After running the model for 10,000 days, what was the average number of loads in each process?

不胜感激!
