... to solve turning problems consisting of multiple process variables and attributes. These methods include analytical hierarchy process (AHP), analytical network process (ANP), fuzzy logic, multiobjective optimization based on ratio analysis (MOORA) method and technique for order of preference by similarity...

... method. The optimum solution has been calculated for MRR, cutting speed (Cs), machining time and surface roughness (SR) (Ra value). A fuzzy logic model using Matlab was developed for the prediction of performance parameters, namely MRR, cutting speed (Cs), machining time (M/c time) and SR with respect...

... optimization of NTM processes. Design/methodology/approach In this paper, GRA is integrated with fuzzy logic to present an efficient technique for multi-objective optimization of three NTM processes (i.e. abrasive water-jet machining, electrochemical machining and ultrasonic machining) while identifying...

... sequence translated from an alternative has the highest grey relational grade between the reference sequence and itself, then that alternative will be the best choice. Fuzzy logic is used here to convert linguistic data into crisp score. Findings The proposed method is validated and compared by taking...
