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,
% S, m1 N* _7 @ 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.
+ l& h" O2 `. f7 q5 L* V Loads are processed by each operator for the following time:# @4 C( R7 t& Z6 Y' b6 E1 m
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.% R& o. P# b% L' }/ D; Q
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.5 u8 h$ O& K* U' Z# j( u# j9 p
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
9 U0 {' U% t+ i [% e' K5 mSend 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.$ K3 I( N* h7 }5 s' P( e# m
9 T( m8 |7 f, F; l r- S
问题:1 b1 c1 D- h7 o* d' S9 j
After running the model for 10,000 days, what was the average number of loads in each process?8 j, x% D" Y) t+ q- w- l2 A
- O" Q9 N9 ?; Q# z) o( h
不胜感激! |
