Multiple-criteria decision making: application to medical devices
نویسندگان
چکیده
At present, complex evaluation of medical devices is very topical. The methods of pharmacoeconomics and cost analyses appear to need some modifications caused by a different character of medical devices [1]. One of the approaches to this task is utilization of multi-criteria decision making [2]. In this study, a methodology for medical devices evaluation is suggested based on the multi-criteria decision making utilized to evaluate the effective part of the cost-effectiveness ratio. This analysis evaluates not only costs spent in the particulat technology (both procurement and operation costs), but also technical, user ́s and clinical parameters of the medical devices. Several methods of multicriteria decision making were compared in this study, among others the ideal point method, the weighted sum approach (WSA) and the TOPSIS method. In the pilot implementation, these methods were applied to evaluate lung ventilator. The goal was to compare utilization of various methods, and to choose the optimum variant. The results were twofold. The TOPSIS method proved to be the best for evaluations for device procurement by medical units (clinics, hospitals). All comparisons were completed with a sensitivity analysis.

A modification of probabilistic hesitant fuzzy sets and its application to multiple criteria decision making
Probabilistic hesitant fuzzy set (PHFS) is a fruitful concept that adds to hesitant fuzzy set (HFS) the term of probability which is able to retain more information than the usual HFS. Here, we demonstrate that the existing definitions of PHFS are not still reasonable, and therefore, we first improve the PHFS definition. By endowing the set and algebraic operations with a new re-definition of P...

In recent decades, the dual systems of steel moment-resisting frames and RC shear walls have found extensive application as lateral load-resisting systems for high-rise structures in seismically active areas. This paper investigated the effectiveness of tuned mass damper (TMD), viscous damper, friction damper, and the lead-core rubber bearing in controlling the damage and seismic response of hi...

In this research study, we present a novel frame work for handling bipolar fuzzy soft information by combining bipolar fuzzy soft sets with graphs. We introduce several basic notions concerning bipolar fuzzy soft graphs and investigate some related properties. We also consider the application of the bipolar fuzzy soft graphs. In particular, three efficient algorithms are developed to solve mult...
