Two-grade fuzzy synthetic decision-making system with use of an analytic hierarchy process for performance evaluation of grinding fluids

A two-grade fuzzy synthetic decision-making system with use of an analytic hierarchy process (AHP) for evaluating the performance of grinding fluids is reported. Five different pairs of algorithms were used in the first evaluation. Their reliability was ordered according to the principle of least squires method. The first three algorithms were selected and used in the second-grade evaluation. The factor weight of the first-grade evaluation was calculated by the AHP for improving the reliability and objectivity of the evaluation results. As an example, three types of grinding fluid were compared and evaluated.
