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,
) v2 V; }0 j) {5 ?3 @  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.
3 b; n& h$ E( v% q" G0 u, R  Loads are processed by each operator for the following time:  m6 k8 S6 G' h5 v+ ?) n$ V% f
  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins." e! o, F, P8 X% ~1 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.
" Z! w& `6 v; _9 {3 s$ P4 x  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
/ a7 `. @$ H8 J* 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.
9 ]. o9 P2 {( U4 F/ P# o( ]4 @3 W" d0 k0 f/ _" ?

After running the model for 10,000 days, what was the average number of loads in each process?/ G) \" D1 o1 f" L! R

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