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,: }5 ?: ~& } q6 _7 L- F2 L, \% L
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.
( {- b+ ~ w! }8 Z Loads are processed by each operator for the following time:+ Q. I* m5 r" u. h: |( Y9 z
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.7 I7 g, R4 n B& q: z
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# ~ Y% U M3 F Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
* H. u$ ~2 m5 tSend 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.! f6 Y( O. y0 w% D

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