Prioritization of Dialysis Department Equipment to Improve Reliability Using Fuzzy Multi-Criteria Decision Making

Reliability refers to the percentage of equipment success during their operation period. Reliability of hospital equipment after selection and preparation depends on proper maintenance and operation throughout the life of the operation. The aim of the current research is to provide an efficient model for prioritizing hospital equipment for inclusion in the maintenance and repair program. Because one of the most important effective things in maintaining the reliability of the equipment is maintaining this equipment at the proper performance level. From the point of view of the practical purpose, this research is a fuzzy survey and Delphi data collection method. The analysis of information about the weighting of indicators has been done through pairwise comparisons and fuzzy hierarchical analysis, and in equipment prioritization through the fuzzy improved TOPSIS model. The results show that the priority of the equipment of the dialysis department as a sample community according to the main indicators of value, nature, amount and conditions of equipment activity, as well as 9 sub-indices of these main indicators, is as follows. The first priority is UPS, the second is reverse osmosis, and the third is dialysis.
