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