the paper presents a multi-factor decision-making approach for prioritizing failure modes as an alternative to traditional approach of failure mode and effect analysis (fmea). the approach is based on the ‘technique for order preference by similarity to ideal solution’ (topsis). the priority ranking is formulated on the basis of six parameters (failure occurrence, non-detection, maintainability...

background and purpose: health indices, regarding to their role in the development of society, are one of the most important indices at national level. success of national development programs is largely dependent on the establishment of appropriate goals at the health sector, among which access to healthcare facilities is an essential requirement. the aim of this study was to examine the dispa...

<span>The concept of the optimization energy management system, developed in this work, is to determine optimal combination from several generation sources and schedule their commitment, while optimizing cost energy, power losses voltage drops. In order achieve these objectives, non-dominated sorting genetic Algorithm II (NSGA-II) was modified applied an IEEE 33-bus test network containin...

controller design and optimization problems, with more than one objective, are referred as multiple objectives or multiple attributed problems. in this paper, a novel method is proposed for designing optimum pid controller that is called genetic multiple attributed decision making method (gmadm). this method is newer than the previous methods and in this paper some options are considered that h...

One of the techniques used to support decisions in uncertain environments is the Fuzzy TOPSIS method. However, from crisp data, this method considers only one fuzzy set in their analysis, besides being a strictly mathematical optimization technique. This article proposes extensions to the original Fuzzy TOPSIS, exploring two distinct versions: to increase the method with the necessary resources...

Vulnerability assessment is one of the effective ways to prevent cascading failures a distribution network (DN). Aiming accurately identify vulnerable parts DN, comprehensive method based on Technique for Order Preference by Similarity Ideal Solution (TOPSIS) considering topological structure and operation status proposed. Considering radial topology structural vulnerability indices complex the...

In this study, we introduce a novel modified synthetic evaluation method (M-TOPSIS) based on the concept of original TOPSIS and calculate the distance between the alternatives and ‘optimized ideal reference point’ in the D D-plane. It could avoid rank reversals and solve the problem on evaluation failure that often occurs in original TOPSIS, so we believe that the mechanism of M-TOPSIS is more ...
