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,! O" [% @2 ^0 A# s1 c
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.
4 x+ M7 P4 `( @" Q+ p) i- I Loads are processed by each operator for the following time:
. [" i' [' ~" c, h! b9 l$ G, d Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.2 `2 m& K9 c" }% [- A0 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 ~$ ~3 u' ]) e0 P Worker_C does the job in a uniformly distributed time between 30 and 90 mins./ }; i2 x( y9 z) H6 ^1 X
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./ B+ _, p+ D; k8 I4 V) S9 `
" V% n& a* D. B; u问题:* q$ `1 D8 b3 G) p" c% P
After running the model for 10,000 days, what was the average number of loads in each process?6 ^0 P) A" P& @- U% p
