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,3 b. S! w* c' \: r; `2 b* }1 \
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.& M; q, g) y6 r! l
Loads are processed by each operator for the following time:8 i4 ]$ _! x. f. X* Y% j
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
5 o7 x1 \* }9 K4 m7 { 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 s; p9 H+ D G& X% y* F9 j- e
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.6 I4 w$ s3 I5 ~ h _( Y, h
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.
