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.
" t0 i" [$ F0 n1 }  l1 z7 }  Loads are processed by each operator for the following time:
& B# c1 a9 K% K  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
5 V; y+ F& n2 [( |& {  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.
5 k1 @4 r" n0 y+ v9 j  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.
, i0 e0 |1 _" H  b& C! d* l

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

in P_C, you need to send to die.

Remember to turn off the animation before you run your model.
