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,
6 o( q% t. [0 `; d- ]9 S( c8 I  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.; u6 r5 F3 k1 X: f
  Loads are processed by each operator for the following time:1 Z' \4 C5 o7 S7 I
  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins." N& W( F$ B9 W
  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.& ~/ U7 c0 S1 C* x% X
  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
6 T3 `' G1 G- k; F! d/ CSend 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.1 t2 Q. j3 L1 N/ l) F- q5 k' t3 ?

' ?# U+ B# n+ e$ \" z问题:) i% k, o0 o% A& E' S
After running the model for 10,000 days, what was the average number of loads in each process?

不胜感激!
