Optimum Casting Process Selection using Analytical Hierarchy Process

This paper present our research work on optimum casting process selection using Analytical Hierarchy Process (AHP). The goal is to determine best optimum casting process for a component. AHP provide a way to rank the alternative of a problem by deriving priorities. Nineteen criteria have been quantified to optimize casting process selection and development of casting process. A decision hierarchy for optimum casting process selection has been developed. In this paper a case study of prototype product has been taken. The proposed methodology takes casting expert opinion on the basis of criteria, product details and alternative casting processes for ranking the problem.
