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,5 e% ~4 O4 J7 p* n! ]+ r. C6 v
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.
- e- t2 _. Z- J9 o5 X Loads are processed by each operator for the following time:! I. w8 j S! J2 d1 z; n
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.: r0 B$ W' H. i( X# x. S
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.' B0 _: Q# M+ |* |: |
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.% G9 Y, _5 C, N) r# F5 f; N
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.
