Optimization of welding process parameters using MOORA method

Abstract

In the present work, application of multi-objective optimization on the basis of ratio analysis (MOORA) method has been applied for solving multiple-criteria (objective) optimization problem in welding. Six decision-making problems which include selection of suitable welding parameters in different welding processes such as submerged arc welding, gas tungsten arc welding, gas metal arc welding, CO₂ laser welding, and friction stir welding are considered in this paper. In all these cases, the results obtained using the MOORA method almost corroborate with those derived by past researchers which prove the applicability, potentiality, and flexibility of this method while solving various complex decision-making problems in present-day manufacturing environment.
