" Global supplier development considering risk factors using fuzzy extended AHP-based approach," Four main criteria-safety, cost, added value, and feasibility-have been used to evaluate the optimum maintenance strategy. This study discusses four maintenance strategies: corrective maintenance, predictive maintenance, time-based preventive maintenance, and condition-based maintenance.
The FAHP is used to compute the criteria weights whereas GRA–TOPSIS is used for determining the ranking of alternatives. The proposed hybrid MCDM model comprises fuzzy analytical hierarchy process (FAHP), grey relational analysis (GRA), and technique for order preference by similarity to ideal solution (TOPSIS) technique. Hence, this article describes the application of multi criteria decision-making (MCDM) technique for the selection of optimum maintenance strategy for pumps used in the paper industry. But the maintenance engineer and supervisor often face failures of the pump. In the paper industry, pumping of cooked pulp requires abrasion- and sometimes corrosion-resistant pumps that are able to handle up to 70 % solids content.
Consequently, it is essential to select the appropriate maintenance strategy. In today’s competitive environment, industries are required to increase reliability and safety level of their equipment with reasonable cost.
