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,4 ~9 j. Q1 q7 I O
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.7 I6 H4 X' ?" R
Loads are processed by each operator for the following time: T u7 P% E1 v( t2 ]
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.! w- x" w- E |" _7 t& h9 L* F5 N/ C
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.
- I$ u) r7 G2 b Worker_C does the job in a uniformly distributed time between 30 and 90 mins.) E5 W3 g4 x5 B/ C' }
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.
