Optimal selection of design schemes for a sparse distributed pile foundation based on fuzzy optimization theory

Abstract

Purpose

The purpose of this paper is to establish the optimization model of designs for sparse distributed pile foundation based on multi‐goals fuzzy optimization theory, to promote the application of the optimization model into project.

Design/methodology/approach

In the designing of sparse distributed pile foundation, there are many feasible design schemes, the selection of designs is a decision making of multi‐goals and factors. Owing to uncertain and imprecise environment in which the designing of sparse distributed pile foundation exists, the theories of fuzzy optimization are chosen as mathematical framework to optimize the design schemes.

Findings

Since relative optimal degree is used to judge, the optional result of using fuzzy optimization theories in sparse pile foundation design selection is more rational according to a site project.

Research limitations/implications

The availability of data and precision of index weight selection are the main limitations as to which model will be applied.

Practical implications

A very useful optimal method for the sparse pile foundation design selection.

Originality/value

The new approach of optimal selection for sparse pile foundation design due to fuzzy optimization theories.
