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 }5 e3 e# N9 O, E+ f  S" B. U: ^1 z& ~
  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.
. u: `0 n: P2 N  Loads are processed by each operator for the following time:
! H8 O  O  ~* ?' B! S7 ~' I1 t  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.2 D1 ^' }; X0 L5 N- z
  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 e& Q1 D5 z4 ?- H2 [/ T  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.* V, U7 i# D, _% k# u& r
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.3 p5 b; Y3 K$ \& @

After running the model for 10,000 days, what was the average number of loads in each process?
