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,* E( e+ \$ Y; i( B
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.
+ o2 D2 l+ _0 j3 p: S, B Loads are processed by each operator for the following time:# x" M+ _3 I+ T0 S
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.1 P. K- q* f7 r! K5 n: ^
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.& Z% i% }# m& C' L
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.- x! ~$ q' z2 m) u8 Z
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.
