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,
K/ t6 p: e! ?' y$ q! V' w 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.
/ i, U: j- `; Q0 W, ] Loads are processed by each operator for the following time:! V' G+ U7 r, W: |+ Q
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
4 P+ x4 M1 R: j: p: \: C+ 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.
1 v9 `# }; @5 A4 u) f3 |- f0 t; | Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
% G9 A, c' M: V0 gSend 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.) t! t# v* c: ]# R6 _. c7 O6 b( n
( @1 S9 B' a8 S& M2 l. s0 H
问题:
% P% c+ f1 v( rAfter running the model for 10,000 days, what was the average number of loads in each process?
+ ?. t. }/ t+ O, }: E$ r0 b7 y9 L2 n
不胜感激! |
