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,
3 r5 k* X$ ?3 z% H! L 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.0 M" ~( X0 }; A6 \4 B
Loads are processed by each operator for the following time:& F$ q$ A; F( s! ~+ S+ @: _
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.3 @2 W* X, w: ~3 S- ^
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 x: T9 d( c% S Worker_C does the job in a uniformly distributed time between 30 and 90 mins.$ V% t3 y# b2 v7 A* u- e# \
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.
