Engineering Cost Evaluation Model Based on Multi Dimension Entropy and Intelligent Algorithm
Abstrak: A complex structure
has many uncertain factors and how to make a more accurate analysis on the
structure reliability by a method is the key in engineering calculation. Rough
set theory is utilized toanalyze the fuzzy, random and uncertain factors and
upper and lower approximation set relation is used to calculate the value
taking interval of reliability index to make reliability index analysis. The
characteristic of this analysis method is that it is not necessary to
distinguish whether the uncertain parameters belong to fuzzy scope or random
scope and meanwhile, it is necessary to determine membership function of
related fuzzy variables or distribution function of random variables and
reasonable value of variable is obtained via objective rough analysis; the
difference from non-probability interval reliability analysis method is that it
is not necessary to make interval standardization calculation for uncertain
parameters and reliability analysis is made in direct utilization of objective
rough analysis results.
