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,
& @8 U/ P3 n% c! ` 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.
6 M1 ^* o, }9 Y& }5 r# ]/ k$ q Loads are processed by each operator for the following time:
7 x, [5 ?/ [+ j8 y Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
% C, }5 Z+ c' {8 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.$ g [0 U+ C9 f0 N' T- m/ x, s' \/ J; p) i5 X
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
7 X# d: N/ R6 U+ L1 i* NSend 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.' R* L5 U/ |3 T: k; \
/ M# M+ Y) Y' z9 j7 ]8 T
问题:. Z) `3 T+ Y2 `; L, y
After running the model for 10,000 days, what was the average number of loads in each process?( b2 @7 }# N' f5 B4 t6 l
, h7 _! Z( B8 k! M1 T
不胜感激! |
