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,
- p; C- H. V2 N' P6 C 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., v9 {% D7 X$ `2 A
Loads are processed by each operator for the following time:
7 \4 y1 x1 K# e! X Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
' P) y7 |, a+ w( w 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.2 F- Z. D" v3 x2 Q7 e+ S
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
3 j% N% I+ |/ y+ J* bSend 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.8 ?) Z0 X+ r8 i
