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,9 |9 [' T7 Q6 G% m
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.
" \0 G" ]+ `6 o0 | Loads are processed by each operator for the following time:
/ ]/ o, z4 _& H1 t Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.( w: S! @5 m3 e$ G/ o1 T, f
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 Z" W( w, Z/ y3 ~/ i7 H Worker_C does the job in a uniformly distributed time between 30 and 90 mins. A. M5 D3 z5 j* V7 ]3 q
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.6 K* x6 b) F' R e7 ?

After running the model for 10,000 days, what was the average number of loads in each process?. P" L3 p& T1 c' y& i1 ?3 ^) S! a
