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,& m; A; e4 d5 L; T& H, E
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! q/ h% U9 [) K9 u; |
Loads are processed by each operator for the following time:
, _. L* b0 I$ X* n' W& K, O9 g/ F0 } Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
; K0 f2 _2 k q/ K ~- w1 R1 l 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.
6 d, Z9 E: B) F+ m/ Q Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
& ~$ K4 @" {8 o- n$ y6 I( rSend 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.
