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,) D$ ^6 c! p4 U% `5 ~. A
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.4 o- v# w* s; a& ^
Loads are processed by each operator for the following time:4 T; `1 ~. q' R0 O4 d6 Y
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins., @- Q. c, O2 T: x w# z) @
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.
. G: [1 S. a$ I& W& \0 T Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
% ~+ o) ?5 G% WSend 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.% Y6 ~/ \) Z* H) c' @6 i Q
/ y8 U" S2 r2 F' X& i
问题:
- k( E+ X. o J, w: y( ]$ z( ~. FAfter running the model for 10,000 days, what was the average number of loads in each process?
