A Framework for Pest Analysis Based on Neutrosophic Cognitive Map: Case Study in a Vertical Farming Initiative

Authors: Wilmer Ortiz Choez, Marcos Quinteros Cortázar, Shirley Huerta Cruz, Katiuska Rubira Carvache
Comments: 6 Pages.

Recently, neutrosophic cognitive maps and its application in decision making have become a topic of great importance for researchers and practitioners alike. In this paper, a new model PEST analysis is presented based on neutrosophic cognitive maps static analysis. The proposed framework is composed of five activities, identifying PEST factors and sub-factors, modelling interrelation among PEST factors, calculate centrality measures, factor classification, and factors ranking. A case study developed in environment analysis for a vertical farming project was presented, ranking factor based in interrelation and incorporating indeterminacy in the analysis. Further works will concentrate extending the model for incorporating scenario analysis.

Competencies Evaluation Based on Single Valued Neutrosophic Numbers and Decision Analysis Schema

Authors: Evelyn Jazmín Henríquez Antepara, Oscar Omar Apolinario Arzube, Jorge Arturo Chicala Arroyave, Eduardo Antonio Alvarado Unamuno, Maikel Leyva Vazquez
Comments: 4 Pages.

Recently, neutrosophic sets and its application to decision making have become a topic of significant im-portance for researchers and practitioners. The present work addresses one of the most complex aspects of the formative process based on competencies: evaluation. In this paper, a new method for competencies evaluation is developed in a multicriteria framework.

Covering-Based Rough Single Valued Neutrosophic Sets

Authors: Yingcang Ma, Wanying Zhou, Qing Wan
Comments: 7 Pages.

Rough sets theory is a powerful tool to deal with uncertainty and incompleteness of knowledge in information systems. Wang et al. proposed single valued neutrosophic sets as an extension of intuitionistic fuzzy sets to deal with real-world problems. In this paper, we propose the covering-based rough single valued neutrosophic sets by combining covering-based rough sets and single valued neutrosophic sets.

Decision Support Based on Single Valued Neutrosophic Number for Information System Project Selection

Authors: Silvia Liliana Tejada Yepez
Comments: 5 Pages.

Neutrosophic sets and its application to decision support have become a topic of great importance for researchers and practitioners alike. In this paper, a new model for decision making in the selection of information system projects is presented based on single valued neutrosophic number (SVN-numbers) allowing the use of linguistic variables with multiples points of view from experts.

More On P-Union and P-Intersection of Neutrosophic Soft Cubic Set

Authors: R. Anitha Cruz, F. Nirmala Irudayam
Comments: 14 Pages.

The P-union, P-intersection, P-OR and P-AND of neutrosophic soft cubic sets are introduced and their related properties are investigated. We show that the Punion and the P-intersection of two internal neutrosophic soft cubic sets are also internal neutrosophic soft cubic sets.

Neutrosophy for Software Requirement Prioritization

Authors: Ronald Barriga Dias, Wilmer Ortiz Choez, Inelda Martillo Alcivar, Wilber Ortiz Aguilar
Comments: 6 Pages.

Software engineers are involved in complex decisions that require multiples viewpoints. A specific case is the requirement prioritization process. This process is used to decide which software requirement to develop in certain release from a group of candidate requirements. Criteria involved in this process can involve indeterminacy. In this paper a software requirement prioritization model is develop based SVN numbers. Finally, an illustrative example is presented in order to show the proposed model.

On New Measures of Uncertainty for Neutrosophic Sets

Authors: Pinaki Majumdar
Comments: 8 Pages.

The notion of entropy of single valued neutrosophic sets (SVNS) was first introduced by Majumdar and Samanta in [10]. In this paper some problems with the earlier definition of entropy has been pointed out and a new modified definition of entropy for SVNS has been proposed.

An Extended Topsis for Multi-Attribute Decision Making Problems with Neutrosophic Cubic Information

Authors: Surapati Pramanik, Partha Pratim Dey, Bibhas C. Giri, Florentin Smarandache
Comments: 9 Pages.

The paper proposes a new technique for dealing with multi-attribute decision making problems through an extended TOPSIS method under neutrosophic cubic environment. Neutrosophic cubic set is the generalized form of cubic set and is the hybridization of a neutrosophic set with an interval neutrosophic set. In this study, we have defined some operation rules for neutrosophic cubic sets and proposed the Euclidean distance between neutrosophic cubic sets.

Multi Criteria Decision Making Using Correlation Coefficient Under Rough Neutrosophic Environment

Authors: Surapati Pramanik, Rumi Roy, Tapan Kumar Roy, Florentin Smarandache
Comments: 8 Pages.

In this paper, we define correlation coefficient measure between any two rough neutrosophic sets. We also prove some of its basic properties. We develop a new multiple attribute group decision making method based on the proposed correlation coefficient measure.

Neutrosophic Regular Filters and Fuzzy Regular Filters in Pseudo-BCI Algebras

Authors: Xiaohong Zhang, Yingcang Ma, Florentin Smarandache
Comments: 6 Pages.

Neutrosophic set is a new mathematical tool for handling problems involving imprecise, indeterminacy and inconsistent data. Pseudo-BCI algebra is a kind of non-classical logic algebra in close connection with various non-commutative fuzzy logics.

Uniform Single Valued Neutrosophic Graphs

Authors: S. Broumi, A. Dey, A. Bakali, M. Talea, F. Smarandache, L. H. Son, D. Koley
Comments: 8 Pages.

In this paper, we propose a new concept named the uniform single valued neutrosophic graph. An illustrative example and some properties are examined. Next, we develop an algorithmic approach for computing the complement of the single valued neutrosophic graph. A numerical example is demonstrated for computing the complement of single valued neutrosophic graphs and uniform single valued neutrosophic graph.
