本人初学auto mod,有一道题目希望大家赐教

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，
  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:
9 l: U" @" U- K' z  }5 j  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
9 I( Z2 [! o/ I  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.
. ~$ |$ J% W, g! ^5 g  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
1 ?4 p# x2 x: |* R" nSend 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.
; O# a0 H8 b/ H, P2 _; n1 j! c
) s4 q0 f* \0 @* U4 i5 J问题：
After running the model for 10,000 days, what was the average number of loads in each process?

send to P_B
end

P_B and P_C is similar

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.
