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,. Z$ z; `7 I t& [6 r
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.; x! U- E4 ~/ d8 t4 ^ l
Loads are processed by each operator for the following time:
+ f, O2 f. p2 W$ { Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
* T3 |- R5 C H0 r7 c( P7 U w 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.
8 B& B3 d' I$ W0 b$ n% @ e Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
( p$ ]3 ~( E5 b) z6 _6 QSend 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.
$ B2 s7 W- \. }5 D+ Z
7 Z6 P T5 _! A, h* O6 A7 ]问题:: w8 C% b; L! S* X, H9 j! J
After running the model for 10,000 days, what was the average number of loads in each process? ~$ M, V% t. ^' l6 I9 ?. E
