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，
0 K! k. k0 B' 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.
" F4 n" O) W; V7 q0 \  Loads are processed by each operator for the following time:
' t! Y6 i6 m+ j  P% s  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
  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.
; G- m3 \6 W; m4 Q4 t9 H6 V  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
Send 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.
7 \; Y0 u) \% B$ P8 b
问题：
After running the model for 10,000 days, what was the average number of loads in each process?
