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 e/ o% Y0 |4 V' }" F
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.5 f: o7 M+ D+ C+ H1 i; |8 Q
Loads are processed by each operator for the following time:
/ I9 \2 h7 q; S' Y8 N. ] 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, j( n) H3 h Y& G* N2 c" G. q
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.- T: I2 N: o( Q4 r9 {$ C* P. n
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.# u, H' Q7 O: X J6 G" h3 e+ U
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.
