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,. w& n' m: S3 J. N! ~
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+ c+ @+ B, D" w) p4 |
Loads are processed by each operator for the following time:
+ x; F( H; r& H1 ~8 t- i& S9 A0 Y Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
6 }2 m( d" |( Q3 y! G 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.
, M. r! [' u1 h' x Worker_C does the job in a uniformly distributed time between 30 and 90 mins.6 ?9 M0 [' j* l( a- {$ p) ^ D9 B6 b
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.
( ]' n: g2 i0 I/ j$ p7 }/ y8 Z1 V& B; M% Q
问题:) e* w o( i5 ~ x O
After running the model for 10,000 days, what was the average number of loads in each process?
