Abstract
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.
Highlights
Selection of materials plays a crucial role for value addition in production, cost optimization, better product development and improve productivity in machine design
According to the basic principles of information theory, information is a measure of system‟s ordered degree, and the entropy is a measure of system‟s disorder degree
The decision matrix is a central structure of the MCDA/Multiple criteria decision making (MCDM) since it contains the data for comparison of decision alternatives
Summary
Selection of materials plays a crucial role for value addition in production, cost optimization, better product development and improve productivity in machine design. Optimization theory is applied for right selection of flywheel manufacturing process. Multiple criteria decision making (MCDM) is the process of selecting the best alternative from a set of feasible alternatives considering multiple conflicting criteria. In precise terms criteria are considered to be 'strictly' conflicting if the increase in satisfaction of one result in a decrease in satisfaction of the other
