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,
8 X) q/ S3 T) 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./ @4 c M+ v. N
Loads are processed by each operator for the following time:" k# g! V4 w$ G, F; v
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins./ X3 P, q" }- n7 q- I/ p/ Q4 v
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.
* @/ n2 m. K. M1 I0 d- S0 ~ Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
% N6 v6 B1 _9 l: ^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.6 ]- k8 d/ j5 E" n
