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,
% B! y% n; b* w- s5 _7 D% @) C8 l  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.
# c1 Z( f1 N- `& T  Loads are processed by each operator for the following time:
2 r/ ?! A* a" s6 R+ a4 t  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.; Q, C: M; p: _+ Z0 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.
0 A9 D: k) h/ L( t3 d  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
: y  J! h6 p  c) X6 `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.' O6 v- u2 J* I- r, F1 w; q

+ R$ O. X& W. h4 V; x  _' S问题:' A& K% ~9 t$ A- S4 P0 t
After running the model for 10,000 days, what was the average number of loads in each process?# X7 E" \2 C$ \6 _

5 C2 B# t: `/ f3 x不胜感激!
