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,
$ Z! r% \* ]4 ^2 M A 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., I6 y; B7 W! I. T
Loads are processed by each operator for the following time:4 t$ ~- s1 R& w0 F% ~
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins./ t8 Z3 i/ s+ z3 p
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& x5 u5 Y9 V l, V' O0 V
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.6 @ t: `% @- `, ?
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.5 D+ L y. ~: E' v8 F$ s

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