Optimal Selection of Gear Material by using Distance Based Approach Method

A deterministic quantitative model based on Distance Based Approach (DBA) method has been developed for evaluation, selection and ranking of gear materials, which is a concept hitherto not employed in selection problem of this kind. As a significant development over and above past approaches to gear materials selection, it recognizes the need for, and processes the information about, relative importance of attributes for a given application, without which inter-se-attribute comparison could not be accomplished. It successfully presents the results of this information processing in terms of a merit value which is used to rank the gear materials. In order to demonstrate the aptness of using DBA method as a decision aid, the results so obtained have been compared with other techniques and methods available in the open literature.
