In 1998, Smarandache introduced the concept of single-valued neutrosophic set as a complete development of fuzzy theory. In this paper, we research on the distance measure between single-valued neutrosophic sets based on the H-max measure of Ngan et al. [8]. The proposed measure is also a distance measure between picture fuzzy sets which was introduced by Cuong in 2013 [15]. Based on the proposed measure, an Adaptive Neuro Picture Fuzzy Inference System (ANPFIS) is built and applied to the decision making for the link states in interconnection networks. In experimental evaluation on the real datasets taken from the UPV (Universitat Politècnica de València) university, the performance of the proposed model is better than that of the related fuzzy methods.}, keywords = {neutrosophic set,Picture Fuzzy Set,Distance Measure,Decision Making,Interconnection Network,Power Consumption}, url = {https://www.journal-fea.com/article_118586.html}, eprint = {https://www.journal-fea.com/article_118586_6ec5d2079f35091c7824d39b7d95de3b.pdf} } @article { author = {Chinnadurai, Veerappan and Sindhu, Mayandi}, title = {Some remarks on neutro-fine topology}, journal = {Journal of Fuzzy Extension and Applications}, volume = {1}, number = {3}, pages = {159-179}, year = {2020}, publisher = {Research Expansion Alliance (REA) on behalf of Ayandegan Institute of Higher Education}, issn = {2783-1442}, eissn = {2717-3453}, doi = {10.22105/jfea.2020.251783.1020}, abstract = {The neutro-fine topological space is a space that contains a combination of neutrosophic and fine sets.

Arranging these components helps to facilitate the efficient management of the set and subsequently leads to achieving the strategic goals. Generally, the components of the portfolio are quantifiable and measurable which makes it possible for management to manage, prioritize, and measure different portfolios. In recent years, the portfolio in various sectors of economics, management, industry, and especially project management has been widely applied and numerous researches have been done based on mathematical models to choose the best portfolio. Among the various mathematical models, the application of data envelopment analysis models due to the unique features as well as the capability of ranking and evaluating performances has been taken by some researchers into account. In this regard, several articles have been written on selecting the best portfolio in various fields, including selecting the best stocks portfolio, selecting the best projects, portfolio of manufactured products, portfolio of patents, selecting the portfolio of assets and liabilities, etc. After presenting the Markowitz mean-variance model for portfolio optimization, these pieces of research have witnessed significant changes. Moreover, after the presentation of the fuzzy set theory by Professor Lotfizadeh, despite the ambiguities in the selection of multiple portfolios, a wide range of applications in portfolio optimization was created by combining mathematical models of portfolio optimization.}, keywords = {portfolio optimization,Data Envelopment Analysis,Fuzzy Sets,intuitionistic fuzzy sets,Markowitz Model}, url = {https://www.journal-fea.com/article_118585.html}, eprint = {https://www.journal-fea.com/article_118585_12a280f76253e26623939cb95848ab1b.pdf} } @article { author = {Voskoglou, Michael}, title = {Assessment and linear programming under fuzzy conditions}, journal = {Journal of Fuzzy Extension and Applications}, volume = {1}, number = {3}, pages = {189-205}, year = {2020}, publisher = {Research Expansion Alliance (REA) on behalf of Ayandegan Institute of Higher Education}, issn = {2783-1442}, eissn = {2717-3453}, doi = {10.22105/jfea.2020.253436.1024}, abstract = {The present work focuses on two directions.

IT2F sets are computed using the interval approach method which is divided into two parts: the data part and the fuzzy set part. The data part preprocessed data and its statistics computed for the interval that survived the preprocessing stages while the fuzzy set part determined the nature of the footprint of uncertainty; the IT2F set mathematical models for each emotion characteristics of each emotion word is also computed. The data used in this work was collected from fifteen subjects who were asked to enter an interval for each of the emotion characteristics: Valence, Activation and Dominance on an interval survey of the thirty Igbo emotion words.

Due to uncertainty all cost parameters of the proposed model are taken as generalized trapezoidal fuzzy numbers. Therefore this model is very real.
