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，
  n8 }9 t% a3 Z) w3 n  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.
  Loads are processed by each operator for the following time:
& K) K) P5 U0 F, |6 o8 E  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
! B) U' t6 g! @2 V  \  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.
' q( ]! g0 @8 D: ~' {& |- q  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
% V+ f5 o. W0 a& D/ H9 ~3 vSend 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.

问题：
* z2 X6 G6 y0 p2 G: pAfter running the model for 10,000 days, what was the average number of loads in each process?

send to P_B

* W- q& J' I2 y  h2 e& Din 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.
