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,
' \0 Y4 i1 k! J+ i3 f 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.+ Q. L. C/ ?& @* q; E6 r$ y3 T
Loads are processed by each operator for the following time:
% |8 _- u% {5 h' H6 B( V' C) d Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
5 j1 B# _0 w9 f2 e' F$ s8 K 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." C) Q; k7 w. b0 `( j' l
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
- n; j" `# _+ [3 {+ _, |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.+ B$ R6 B. [( f4 N8 G$ ^: p
! r3 w6 R# r+ F" ^4 y" p问题:
- [/ ?- h2 c+ U* T MAfter running the model for 10,000 days, what was the average number of loads in each process?
+ X5 R( U }, X$ H# `. K2 r2 ]+ Q! h* u
不胜感激! |
