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 ?. b5 _8 J& z" }" n 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.
" ~3 B4 V. Y+ t' P2 ? Loads are processed by each operator for the following time:# \; o+ `, a8 p% b' Q q# W
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
& A- H- w3 [9 U* h 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.4 m! ~" n( X1 l. e' r. V
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
# K6 F% T3 |8 P `/ G# w! dSend 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.. {5 y2 u( w0 {" ~6 F
