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 j# F2 n! f6 w G$ U 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.
) [, C. \0 S" g% \ Loads are processed by each operator for the following time:
9 z' O5 X* l5 n' c Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins., |: G! x& Q0 }
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.
0 E7 F5 ^! m- Q Worker_C does the job in a uniformly distributed time between 30 and 90 mins.5 [2 I9 k( }: G, c2 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." t7 B' r7 o S* B& v
5 J" P5 ]4 `) A) V" j" j6 v- M8 c9 ~问题:* t: C/ y0 N1 E# R
After running the model for 10,000 days, what was the average number of loads in each process? } X& N8 f/ D5 t% K- g) Z
8 z `0 P, x, w O
不胜感激! |
