“…The third model of preference analysis, based on the PROMETHE III method, associates for each alternative a 1 an interval [x a 1 , y a 1 ], based on a standard error value (16), from the standard deviation of net outranking flows, where each interval is obtained by Equation (17). This model of analysis enables defining the complete ranking, where (18) and (19):…”

“…In this context, of several alternatives, criteria, and complex scenarios, the Multi-Criteria Decision Analysis (MCDA) can be favorable to support the decision-making process, presenting techniques that allow the decision-maker to structure and evaluate complex problems transparently, introducing quantitative and qualitative criteria [12][13][14], defining the importance of variables in an interactive process with other technical-political actors [15]. Contemplating the context of multi-criteria analysis regarding the evaluation of actions in defense scenarios, some previous studies are presented in [16][17][18][19][20].…”

This paper presents a new approach based on Multi-Criteria Decision Analysis (MCDA), named PROMETHEE-SAPEVO-M1, through its implementation and feasibility related to the decision-making process regarding the evaluation of helicopters of attack of the Brazilian Navy. The proposed methodology aims to present an integration of ordinal evaluation into the cardinal procedure from the PROMETHEE method, enabling to perform qualitative and quantitative data and generate the criteria weights by pairwise evaluation, transparently. The modeling provides three models of preference analysis, as partial, complete, and outranking by intervals, along with an intra-criterion analysis by veto threshold, enabling the analysis of the performance of an alternative in a specific criterion. As a demonstration of the application, is carried out a case study by the PROMETHEE-SAPEVO-M1 web platform, addressing a strategic analysis of attack helicopters to be acquired by the Brazilian Navy, from the need to be evaluating multiple specifications with different levels of importance within the context problem. The modeling implementation in the case study is made in detail, first performing the alternatives in each criterion and then presenting the results by three different models of preference analysis, along with the intra-criterion analysis and a rank reversal procedure. Moreover, is realized a comparison analysis to the PROMETHEE method, exploring the main features of the PROMETHEE-SAPEVO-M1. Moreover, a section of discussion is presented, exposing some features and main points of the proposal. Therefore, this paper provides a valuable contribution to academia and society since it represents the application of an MCDA method in the state of the art, contributing to the decision-making resolution of the most diverse real problems.

“…Tools or techniques using the center of gravity are deeply embedded in our daily lives [1,2,3,4]. For example, when creating animations, a motion generation technique that finds and moves the center of gravity of a character in order to provide a natural motion is considered an important task in the field of computer graphics [5,6,7,8].…”

The center of gravity of a three-dimensional object found through an experimental method can be made easier and faster than when calculating the movement manually in order to make the movement in computer graphic images look more natural. In addition, in various sports such as skating, the score can be increased by appropriately moving the position of the center of gravity. Lastly, it is expected that it can be used even when the performance is high in the manufacturing process to increase the stability and speed of various means of transportation (eg, automobiles, airplanes, etc.).

Online monitoring of gases dissolved in transformer oil is widely applied. Improving the performance of dissolved gas analysis (DGA)-based fault diagnosis methods by exploring new features of time-series data has become an appealing topic. In this study, a new type of correlation features between characteristic gases was extracted from timeseries data based on the maximal information coefficient (MIC), and a fuzzy inference system was established. After the introduction of the principle of the MIC and a method for calculating the MIC-based correlation features, the dominant symptom features that can be used to classify fault types were extracted through the receiver operating characteristic curve. Then, fuzzy rules were learnt, and a fuzzy inference system was designed. In addition, to improve the feasibility of the method, the Newton interpolation method was used for adaptation to the existing sampling cycle. The diagnostic results of the test data show that the proposed method has excellent performance and outperforms some prevailing traditional rule-based methods as well as some artificial intelligent methods. The results also show that by exploring new correlation features from time-series data based on the MIC, the performance of DGAbased methods can be improved.This is an open access article under the terms of the Creative Commons Attribution-NonCommercial License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited and is not used for commercial purposes.
