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,
+ W+ p& M7 j0 Y# k. m 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.; q* K9 d2 \' T, o7 R/ q
Loads are processed by each operator for the following time:- ^: C8 _2 L9 ^& E- Y
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
4 g0 W/ [8 [0 g5 E 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.9 M* x% i: P6 r
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.( z2 K9 Z* c. i
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.9 ^ l, F: B; Z1 a8 R/ T
6 M# r) C3 j: J* O4 g/ g7 h问题:- m3 d# ]1 u+ S* ]) o& U( h8 g* T1 \/ P
After running the model for 10,000 days, what was the average number of loads in each process?
7 x2 P) v" Y6 k1 Y, H7 O' S9 T. q: L# q4 y! H
不胜感激! |
