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，
" a" o3 l3 l: }* M  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.
- j4 |8 v8 e& L+ A0 X9 m  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.
; D1 v; U% d! F' c2 e; y' K1 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.
# W/ e( G8 Y+ Q" \! |* e: |

After running the model for 10,000 days, what was the average number of loads in each process?
