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,
* q0 `) x" P2 x8 v9 K 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.
" A' I& N+ r- v$ t6 N% V Loads are processed by each operator for the following time:
% `/ |6 ?9 l, Q5 e Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
& @+ G- e5 \6 H! g; J 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./ n. v7 |6 u+ q. k; ~
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.0 W8 r( n7 |1 ^) C' h. l# _+ 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. K* h* k: E" G- e/ l4 |! w/ [
. G. d0 \) I! p d( Y问题:- m. Y( B r O! j0 y
After running the model for 10,000 days, what was the average number of loads in each process?
