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 U% V0 Z# ?/ N+ m, N% R' }8 r0 A. v
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.
0 p2 ~+ i* d2 K( ?, o2 c- p' W& `& L Loads are processed by each operator for the following time:
& k1 z# B$ d- b9 ^" @1 a3 J Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
, A, U' F, ` O- m6 K6 n. P# p; i 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.
; W4 R( A8 {8 K n. f7 [ Worker_C does the job in a uniformly distributed time between 30 and 90 mins.4 y( ~: ?, W' c
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 }3 K% L1 n9 O% I/ G1 R
