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,
8 j3 ?& o6 b6 K+ E 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.
" r# P; L% |2 v0 b. O, v Loads are processed by each operator for the following time:8 p$ b _. G2 Y2 U3 _2 x$ S
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
% C* ? e9 y! J: `* W b# \' x 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./ v# c, s: q3 _$ @* _( `3 D
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
# N" K; k) W& y' ?0 ? N3 Z7 tSend 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.
