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,
: o) F' ]' m9 J; u! [ g3 m2 x 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.
" c7 B' W+ y4 X/ h8 K Loads are processed by each operator for the following time:
% D5 R( i/ `+ V, N7 k Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
. X% V7 a1 Y4 l/ B2 U$ H2 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.* S; g; T& M/ e) h
Worker_C does the job in a uniformly distributed time between 30 and 90 mins., @# j4 ^: m v4 v5 M* D
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.
