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* v# P6 R/ z" ?2 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.( A6 g( z- T, Y, k
Loads are processed by each operator for the following time:
" x8 _2 e( h8 r& [; c Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.. x& ?6 L7 X2 q0 o- a' `% ?
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.
' y7 r4 @7 t5 P% \ T8 @ Worker_C does the job in a uniformly distributed time between 30 and 90 mins.8 i f7 o$ Q K" {3 D% o
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.- O2 B2 w6 g# R6 Z
5 k* c0 b% L4 P7 r8 I" b* b) W
问题:- Z: A: ^( v& s: q
After running the model for 10,000 days, what was the average number of loads in each process?

不胜感激! |
