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& U% C8 s. Q: @; ?! k( ~" I
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.' j" A! f5 W' G
Loads are processed by each operator for the following time:
9 a) |; `; Z/ T+ V3 k Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
# i/ j4 d: c& q, C. x5 ?! G 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.8 h# w; _. H9 F6 j
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.' S+ T- E5 Q" A: U8 ~. _
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.7 V6 _' ?) Z. `/ z
