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，
/ g* A- W. J  C' e6 M( V3 Q  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:
  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
; U/ r  _3 }. E, D0 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.
  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
  _' W  C" j2 A3 C+ {8 A) 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.

* x" j0 L0 a' m/ m" a; c问题：
After running the model for 10,000 days, what was the average number of loads in each process?
