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,
, d9 m8 H8 u9 i& 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.
$ R1 y w. E: f5 u* c7 v# R Loads are processed by each operator for the following time:
: S8 X: \ c$ [$ w) }( ?6 T! t Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
- M E: {7 b6 ?& i 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.( }& V; I8 n0 p8 A
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
$ Q2 U, @' i( nSend 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.% U. C" {' Q0 s) P$ y+ K
. X2 e2 z6 ~: H# F; L+ |! B" {; `
问题:1 F! u6 u+ |5 X! t, F
After running the model for 10,000 days, what was the average number of loads in each process?

不胜感激! |
