Integrating Fuzzy Dematel and SMAA-2 for Maintenance Expenses
Journal Title: International Journal of Engineering and Science Invention - Year 2017, Vol 6, Issue 2
Abstract
The majority of the allowances being transferred to public institutions are mostly spent for buying new equipment, materials, facilities and their maintenance and repair. Some of the public sectors establish their own plants in order to reduce the maintenance and repair costs and gain ability to perform these activities. However, developing technology and variety of materials make their repair and maintenance activities more expensive for them. In this study, vital criteria for a public institution are determined. By using Fuzzy DEMATEL (Decision Making Trial And Evaluation Laboratory) method the degree of importance is identified by two defuzzification methods and the alternatives are ranked by using SMAA-2 (Stochastic Multi Criteria Acceptability Analysis) in three scenarios. The results show that different defuzzification methods change the order of preferences.
