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," ^: x P) E) n9 Y% ^" a! C
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.
4 b# c& Y8 ~9 Q3 u P Loads are processed by each operator for the following time:+ t7 N( P% U7 w" j0 y' a( g/ h) i
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
- _4 j/ N& {; I3 { 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.
5 X& Q1 J/ w4 f7 ]- b- J; T Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
4 i- O3 Y8 X6 u8 q: T: qSend 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.
