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,
, K6 _1 i+ _; O* j" 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.
% ]8 x" K+ ?0 V4 Y6 T: c Loads are processed by each operator for the following time:3 Z/ _; Q: y5 b% h7 r5 _5 `
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
& Z% g* z9 c+ b! G+ z 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.
' C0 L1 n& P6 a Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
1 j! L8 `6 `8 `" P3 ESend 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.
