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,# r. I3 A! t2 S( f3 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.
) [# f/ J) r6 l$ ?) l! O Loads are processed by each operator for the following time:5 J3 ?2 T* w) K# \- i: u: L7 e. p
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
. X4 h0 L6 K: Q' W9 L' j 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.

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.9 ~ x, m! B |. ]$ L6 N
