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, S, a+ ]: I 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.* c$ \* m5 k" [
Loads are processed by each operator for the following time:5 v/ E& X# j1 R6 n! ^- k6 y
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.5 c4 Q9 j# }1 D7 B) t- G4 o2 _
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.
\8 x& D+ [- n% Q Worker_C does the job in a uniformly distributed time between 30 and 90 mins.' o& n p6 D, |: j' s6 |/ ?6 a5 z
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.
