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,8 F# m, H/ {) `3 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.# c- M; }+ H7 i
Loads are processed by each operator for the following time:7 |) `9 w5 q/ @; T$ n- n
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.: m! ]9 m4 W3 f* Y. h9 x+ ?4 B
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.5 {' H" k. @7 O
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
+ Z1 z9 e1 C8 RSend 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.. D0 x- I' D* L9 ^4 ~+ W9 Q3 m
