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,4 U4 p" Q, i! L. m3 S7 ~2 g8 l
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.% G8 u9 `. e/ |; w0 O
Loads are processed by each operator for the following time:+ r: i/ L9 ]8 L9 [5 b. ^
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
! A, s. v- I- V 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.
) W6 A4 }# e" l2 ~8 e2 P0 g6 Y Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
3 \7 \. g! p7 y# b) ]5 BSend 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.
