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,
: A( Z& y# L0 M& u 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.
% E4 H6 [ D/ `5 U6 @1 X Loads are processed by each operator for the following time:
8 c* u0 c2 ?; H0 o- |$ C8 P: G5 R Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
0 |9 u0 Z% n! O1 Z 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.
" H/ r! R$ ?( l$ K) k Worker_C does the job in a uniformly distributed time between 30 and 90 mins.* N' ^( w0 a! U+ E) H/ q8 {9 [
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.
