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,
1 w2 g, s+ S+ |6 Y% B3 q  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.
4 b) Z, W& T, w4 {* v% `  Loads are processed by each operator for the following time:$ E" G8 c8 k0 `" I1 @2 N2 |
  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.: O- Q- _2 e3 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." A6 J+ S! d/ C, H* v9 l
  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
  l5 B" m  z/ Z$ I% x; f' y1 {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.+ i7 A( W3 |4 K5 z
  k4 V7 B0 W; d% \! ]$ H/ H3 I
问题:0 S1 R2 u7 c3 n) U' X
After running the model for 10,000 days, what was the average number of loads in each process?
2 q. {) i/ d( m% C8 T! w; e3 B- i2 D( ^: f$ T- h2 x
不胜感激!
