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,* B% b! _ f. W0 H# ~( X
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.3 ]6 T6 D/ U, \( t
Loads are processed by each operator for the following time:
! [0 D! k% p v5 }6 V& @8 } Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
2 v/ S# C! u+ P4 E( I* 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.
6 j( l5 n2 W, v5 u: B% q Worker_C does the job in a uniformly distributed time between 30 and 90 mins.7 ?$ ?( t$ D+ F* W- q- p, d
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.
