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,3 W' ~6 x9 l% [/ h5 F" b1 J6 ]
  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.
9 a# ]% @- I" N0 _  Loads are processed by each operator for the following time:
. l9 x0 ~0 d# c% X  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
7 t0 O  J8 g! d2 W; V, l  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.5 e! L1 M/ T' h1 H5 F
  Worker_C does the job in a uniformly distributed time between 30 and 90 mins./ W1 j( D5 ~7 Y9 ]& E9 T7 [
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.
* _, A! R4 Y3 ~+ ^. c
4 P5 Q9 A  i, t: P问题:! V/ D% J+ O. A9 E0 r8 P) A+ M
After running the model for 10,000 days, what was the average number of loads in each process?) i- Z- W! ^6 B$ ~1 [

不胜感激!

Then You need to add a L_Control to drive up the whole simulation. and a Run Control of 10000 days.
