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，
* C- ?) E  s; R  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.
% s6 v' U; H& k2 z: l  Loads are processed by each operator for the following time:
5 g% Y! P8 k# v, l1 F  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.
9 x$ h* r# I& Z7 S9 q, w- t% 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.
. e' {- E7 n5 y/ ~3 L) E
$ B/ J& l5 r) |0 f) M问题：
After running the model for 10,000 days, what was the average number of loads in each process?

不胜感激！

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