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，
! y; B7 f0 v; P. n0 ]( h) 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.
/ S0 a* K7 U7 P4 t( [' y3 w# M% S  Loads are processed by each operator for the following time:
  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
& N  w9 T6 H2 E7 e  I: n  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.
  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
, e1 T8 R. s* A$ {7 }5 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.

5 e( J3 G, n) K4 K' `4 e5 m" J2 N7 B问题：
After running the model for 10,000 days, what was the average number of loads in each process?

begin P_A arriving

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