CNC Machine tool selection using MCDM techniques and application of software SANNA
نویسنده
چکیده
Machine tool selection is a very complex procedure. It involves deep analysis of various factors affecting functioning and performance. CNC machine tool selection is also a such kind of problem[5]. Objective of this study is to perform various MCDM methods for selecting most appropriate machine tool. AHP method is used to calculate the weights of various criteria[10] . The numerical problem considered for MCDM application is related to CNC machine manufactured by leading companies of the world. Various criteria are well examined and weightage is assigned to each criteria on this basis. There are used three normal MCDM methods viz. TOPSIS , MOORA, COPRAS and one outranking method namely ELECTRE I. Weights obtained by AHP method are used for all successive applications .MS-Excel add-in application SANNA (System for ANalysis of Alternatives) is used for evaluation through TOPSIS and ELECTRE methods. Results demonstrate an effective method for selecting CNC machine tool. Analysis of complexity is carried out for each method to arrive on best method along with the best alternative. Keywords— CNC Machine tool, MCDM, SANNA, MOORA, TOPSIS, ELECTREI, COPRAS
