Selection of best material considering technical and economic aspects is an important key issue of pipe material design. Basically, it is a multiple attribute decision making problem. Through entropy method, it gives us unbiased and optimized weight factor for each alternative and MATLAB approaches accurate calculation. Pipe is manufactured by various stainless steel. Selection the best material among various steel is one of the difficult and subtle tasks. In this paper, the methodology of Multi-Objective Optimization on the basis of Ratio Analysis (MOORA) and Simple Additive Weighting (SAW) are implemented first time and comparatively Analysis is to find out best material for better product development.
This research venture one of the major concerns in the field of expert system. Material selection an important key issue of machine design. Objectives of computerized selection procedure are reduced to personal bias and gives the more accurate optimized result. The concept of entropy; to evaluate the weight factor for each alternative material property or performance index, and the other is TOPSIS and SAW; to rank the candidate materials, for which several requirements are considered simultaneously. Sensitivity analysis is introduced here for better performance of selection.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
