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,
6 L0 Y, u: N# q5 @ @1 F0 f 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.- H3 F0 _' x7 w
Loads are processed by each operator for the following time:
* _. A* g, Q9 X7 n( ^; s0 p. W9 X7 f Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
. s" Z# F N! {9 T 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.
* Z" R6 i2 q1 d7 R. F Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
* R3 o% _# M$ 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.5 s/ _ f+ I' |: k4 B5 d1 p
9 @+ X/ o8 p: c6 a问题:
- b- U1 I9 T: B/ SAfter running the model for 10,000 days, what was the average number of loads in each process?

不胜感激! |
