Method for Attributes Similarity of Deep Excavation Construction Plans Based on Interval Type-2 Fuzzy
摘要
Abstract
The key of case-based reasoning for the plans reuse in deep excavation construction is to calculate the attribute similarity. Attribute values are traditionally given based on experts' experience and then converted to the same type to calculate their similarity,leading to inaccuracy and information loss during the conversion of attribute value, which affects the performance of case retrieval. Therefore, this paper introduced an interval type 2 fuzzy logic method to obtain the interval fuzzy value of attributes so as to enhance the uncertainty description. Similarity (distance) algorithm is employed to calculate the attribute similarity according to the characteristics of attribute value directly. The comprehensive similarity between projects can be obtained by assigning different weights to the attributes. Finally,a case study was used to test and validate the proposed approach. Results show the proposed approach can effectively consider the uncertainty attribute and calculate similarity directly, which reduces the information loss caused by the conversion of attribute value from one type to another and improves the retrieval performance of construction plans.关键词
