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,
, B4 z+ o. D3 r3 h 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.
& \$ O/ p2 x- ^ Loads are processed by each operator for the following time:
$ J* m$ e2 h; r/ p, P/ U Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
. n. Q$ Y1 J3 A" ~ 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.
# K! Q- \9 ^& f9 R8 Y' ~) [ Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
2 W) D1 i |9 Y; ySend 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.
