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,5 ?+ M z, @; 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.
! `6 w* V" \; a# X4 K Loads are processed by each operator for the following time:
8 M$ ~ [0 i, r" R9 m5 k Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
4 {) d) W- o1 G+ b, l3 j2 b 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.
7 \2 c+ M) v& y2 m8 r: {; H, o+ ~ Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
) x; l y. X; o) {3 X; ]- k$ B& 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.
; E7 K! a$ N! _7 M
. g9 C4 \2 s" P% s; q问题:" |/ [% R% _" K3 Y; U
After running the model for 10,000 days, what was the average number of loads in each process?" J9 N J1 f- e3 Z, h" r

不胜感激! |
