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,: p6 \% z) X5 I+ `1 k' Z
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.* j d6 U( I( q B! U
Loads are processed by each operator for the following time:
) B4 b A8 `: G5 n _ Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.! f4 k5 _' F/ s
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.
( W4 ~) k) O. E% c Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
1 q' F; r, y) x6 O' `% ASend 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.
* ~ w. e+ | `1 d( c' y7 U0 o, w. d7 G+ S6 x( I j$ s
问题:$ Z. j4 K, Y) o" Z" w' B
After running the model for 10,000 days, what was the average number of loads in each process?

不胜感激! |
