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,+ Z2 q& B! D- d( j1 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.
+ D' j+ C- F/ Y" O4 } Loads are processed by each operator for the following time:2 D U0 L3 n/ p$ w6 g; z
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.4 p7 i9 s, X- r, C
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.
q' a% l# Z" C! H Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
/ R. b5 T9 q' u. ySend 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.! `5 D( I4 R9 L# L; W. [' a( u
) j4 z# Q$ }1 }/ F. r
问题:. ~6 [. T1 f/ D6 O2 V+ g5 R
After running the model for 10,000 days, what was the average number of loads in each process?; d1 q8 r+ f( s) e5 e! J+ A/ H
, H" \0 I4 y+ e, J$ W, u不胜感激! |
