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,0 \- P# t1 T4 H* 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.
5 W9 ]8 i, L: K+ Z! |- x  Loads are processed by each operator for the following time:9 w; F) J' a$ \! P) B6 \, t$ w
  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.4 |# Z) c% f- }% y% o: v8 J! u
  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.6 c, I- C* }) f, t6 o, D
  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
' _( h. [2 {( c+ X( s1 jSend 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.' x6 @3 i2 a3 r) y! O8 A1 n' b

After running the model for 10,000 days, what was the average number of loads in each process?% N$ ?0 u  L$ m) }
