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 g  j' \5 t! J5 @
  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! O: b: b. q+ n  Loads are processed by each operator for the following time:; p) s6 ^0 h5 b- O. X5 c
  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.$ j+ I/ U: t) c
  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., h/ u4 x- X5 t: B3 B; c  D
  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
7 I3 J4 [! N, qSend 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.
$ H3 F* g) @0 O% e9 t4 |$ J1 A$ `7 j, R+ S% Y4 N
问题:- z8 E6 d9 n3 {8 W
After running the model for 10,000 days, what was the average number of loads in each process?

不胜感激!

in P_C, you need to send to die.

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

Remember to turn off the animation before you run your model.
