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+ K0 d: b. d; T$ _* w
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.9 e# }' u# R! `9 M! [0 X
Loads are processed by each operator for the following time:% k1 j. B6 D4 [/ O* Z8 p! a
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.. \) P5 ]! x8 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.
/ [+ v5 U* c# o. C0 M" v7 Z Worker_C does the job in a uniformly distributed time between 30 and 90 mins.! e% F4 s( | _, L3 Y
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./ M7 w% e0 r- S4 V0 n7 v$ x
