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,0 H* a8 i% h- j- K6 X% j
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.( D, ?% t* y) n, J# k
Loads are processed by each operator for the following time:
: G) ?' \2 z q Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
1 e- I6 I& h% e9 Q+ v2 W 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.
% U& p- \) c2 d$ Z Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
6 x5 M) q: H' i5 XSend 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.' l) E( b( `: O. R) y6 \3 A
