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,( g' H; j! w9 B9 b4 E
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.2 \& B# D! V& [: t
Loads are processed by each operator for the following time:
7 x+ b8 y1 ~& r0 e5 N Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
G- C& I9 I" h3 g D3 ^ 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.
( j" B- Z/ _& _. O Worker_C does the job in a uniformly distributed time between 30 and 90 mins.& {- F3 j. O9 z/ E/ n1 m! b! z5 P
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.# Q# [- t" ?& X1 u
