MULTI‐OBJECTIVE DECISION‐MAKING FOR ROAD DESIGN

TLDR

Multi‑objective analysis is a popular tool for solving economic, managerial, and construction problems. This study develops and implements a methodology for multi‑objective optimization of multi‑alternative decisions in road construction. The methodology employs the MOORA method, which analyzes a matrix of alternative responses on the objectives. After reviewing related work, the MOORA method was selected and a case study demonstrated its application, identifying the best road design alternative.

Abstract

Multi‐objective analysis is a popular tool to solve many economic, managerial and construction problems. The objective of this research is to develop and implement a methodology for multi‐objective optimization of multi‐alternative decisions in road construction. After a rough overview of the articles dealing with the multi‐objective decision and assessment of road design alternatives described by discrete values, Multi‐Objective Optimization on the basis of the Ratio Analysis (MOORA) method was selected. This method focuses on a matrix of alternative responses on the objectives. A case study demonstrates the concept of multi‐objective optimization of road design alternatives and the best road design alternative is determined.
