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,2 s; B% t1 S2 D. D g$ n( q
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 _( y G8 S% e Loads are processed by each operator for the following time:
4 x4 S+ Z2 [" c% ?! T& F: [ Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.1 Y$ L7 U# G' ^/ _$ G4 R4 ]
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.
; k, v' l0 `8 }9 @2 Q9 W$ {5 k Worker_C does the job in a uniformly distributed time between 30 and 90 mins.3 N" B1 l+ T' O, i
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.
