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,
1 ^; s( F: \7 m2 U' `# Q% P4 G. Y 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.
5 R/ g$ }' g8 m Loads are processed by each operator for the following time:- m" e# S; D5 O$ C5 _. I
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.& a+ J2 W* U/ _0 P D, Z. u
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.; L6 ^7 w; L7 n# K" M; N3 `3 q+ g5 F! U
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.1 C" ]; G. M) }$ W8 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.. Q9 H/ o3 z4 N0 ^5 z- Y
