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,
, h. d3 p; ]! M7 I# B' k6 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.
6 G7 R) E; z% M Loads are processed by each operator for the following time:
) S" d& P& ?$ @+ Y# G7 r Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
* x( K+ A3 T4 ^6 { 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.' F' h% T8 F ~$ R! [ h1 \) G
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
4 C0 S( E, o' ?+ 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.
) v0 j8 Z9 g+ q
) h6 Q. f0 x, u- _# e问题: b9 D5 E; c7 P- `6 g
After running the model for 10,000 days, what was the average number of loads in each process?
8 f8 ~4 E. t/ ]# Z! N
6 B# d; h( a+ K( C不胜感激! |
