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,& K, _/ `. j! ]$ F. 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.+ @) x9 ^% N. r2 v, E1 y7 A
Loads are processed by each operator for the following time:
2 I9 j3 R$ o) Z4 u9 R' R Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
- B5 {; h& D4 R, H 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.
. h/ h. }, {/ e( E9 p1 w6 b Worker_C does the job in a uniformly distributed time between 30 and 90 mins.7 s5 u; {2 V @7 }1 e
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.1 Q. C' k/ h/ S6 ~% D( j
