Machinability Index Evaluation using AHP and PROMTHEE Method

A B S T R A C T The manufacturing sector frequently face the problem of assessing a wide range of alternative options, and selecting one based on a set of conflicting criteria.This paper presents a methodology to evaluate the machinability of work materials for a given machining operation using Preference Ranking Organisation Method for Enrichment Evaluations (PROMETHEE).The method is improved in the present work by integrating with analytic hierarchy process AHP. A universal machinability index is proposed that evaluates and ranks work materials for a given machining operation. The index is obtained from a universal machinability junction, obtained from the universal machinability attributes. The procedure is illustrated by means of an example.
