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,, `' u! P! ?# w0 F2 }9 [
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./ {3 y( K* Z' T
Loads are processed by each operator for the following time:* _9 L' h& u* p2 q% K
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
0 o3 q9 \) B' G" P+ g+ ?9 | 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.0 b6 f8 F/ o1 r! }+ Z0 I
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.2 ~$ m5 ?1 ^/ k
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.3 N4 \ P' N/ h7 O, o) B
