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,' n1 b, V: o8 r+ T
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.
- {' ?' }/ _. H9 _7 M- Z Loads are processed by each operator for the following time:
+ }+ k/ E7 f; X6 Y3 t% ~ Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.6 F) E4 a2 p% x& d
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.
- h7 i; }% @' h* O1 J- ^; A& N& ~ Worker_C does the job in a uniformly distributed time between 30 and 90 mins.: h, A; k0 z \9 k
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.& q) o; h5 X7 \0 }) r

After running the model for 10,000 days, what was the average number of loads in each process?4 D% X/ Y( `1 U1 k5 b
