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,' r6 z- n9 g0 J8 X7 D$ _& 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.: w- q$ y' f& }
  Loads are processed by each operator for the following time:. w0 ?- G, m7 h1 C
  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
- j1 c1 f) O! P4 O- q0 R3 Q  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., {, R2 R' n7 \- G4 R& |
  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.) J$ a' G5 e( ]. ]2 M# p( P% X
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.) C, W* N6 i. K

问题:  t' }. Z% U7 l  `5 R$ n
After running the model for 10,000 days, what was the average number of loads in each process?
