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 Y' `: r: l$ v) i- h2 R: m" 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.
0 a, r4 W' R; U0 X$ R Loads are processed by each operator for the following time:- y* W( O H9 ~# u8 f
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
. v" ~: c) ]4 ^+ @1 g) `2 d 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. }" x4 `2 v' J5 }- g& v+ p, {
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.8 }6 `- y% N$ b! B4 A
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.
4 S! u% c# p2 y' } {# c' ]$ b+ u$ V4 U
问题:6 \, h$ B0 o) {. ^
After running the model for 10,000 days, what was the average number of loads in each process?) @3 H$ q7 q9 c1 @: y* J( |/ e
: ]1 [* r! F5 f) I3 C8 H/ E
不胜感激! |
