It is considered a complex problem given that it involves different aspects such as the alternatives to evaluate, the multiple criteria involved as well as the group of decision makers with different opinions. In this sense, the literature reports several methods to help in this difficult activity of selecting the best supplier. However, there are still some gaps in these methods; therefore, it is imperative to further develop research. Thus, the purpose of this paper is to report a hybrid method between MOORA and intuitionistic fuzzy sets for the selection of suppliers with a focus on multi-criteria and multi-group environment. The importance of decision makers, criteria and alternatives are evaluated in terms of intuitionistic fuzzy sets. Then, MOORA is used in order to determine the best supplier. An experimental case is developed in order to explain the proposed method in detail and to demonstrate its practicality and effectiveness.

Therefore, that in turn will cause an impact before the imminent entry of industry 5.0 in a competitive environment. In addition, as well as identify the possible barriers and benefits that we can have in industry and in turn in the social sphere. In this sense, some questions will be proposed such as Is I 4.0 focused solely on technology? Does I 4.0 help meet the implementation of I 5.0? Are they interdependent or dependent on each other? What technologies and processes will we have to adapt to meet the purposes of I 5.0? Subsequently, an analysis of the logistics process of an industry in Cd. Juá rez will be carried out to generate a proposal on improvement to the logistics process using the strategies of industry 4.0 and contemplating the objectives of what would be an industry 5.0, verifying these theories with a program of simulation to later see the possible scope.

At the moment of applying this methodology, we generated which are the levels of importance that the company requests to select one of them, more than anything are factors or points that each company chooses for a better management of its resources, thus taking care of the part of time and money. In the industry where this observation will be made, the main levels of importance requested are the following: Quality, Time, Price and Reliability of the supplier.

SCOR es un modelo estándar basado en una estructura que permite eslabonar procesos logísticos, procesos de reingeniería, indicadores de desempeño, benchmarking, mejores prácticas y tecnologías dentro de la cadena de suministro. Además, por medio del modelo SCOR se pueden encontrar los componentes de la cadena para la generación de una SCORCARD que ayude en la administración. En la cadena de suministro de generación de abono orgánico a partir de la lombriz roja californiana, se identifican los niveles del proceso, indicadores clave de desempeño y atributos a modo de diagnóstico para posteriormente sugerir una SCORCARD ajustada al contexto. En este sentido, se pudo evidenciar que la aplicación del modelo SCOR organiza y permite mejores mediciones a lo largo de la producción.

Supplier selection is typically a multi-criteria decision making (MCDM) issue, as there is a lot of uncertain information. In order to overcome this issue, The Pythagorean Fuzzy Set is applied to handle the uncertainties involved in comparing the alternatives, criteria and opinions of decision makers. At the same time, a potential of Dimensional Analysis is a technique which deploys an association of the criteria capturing the interrelationship normally present in MCDM. In this sense, the purpose of this paper is to evaluate the suppliers in a supply chain cycle using Pythagorean Fuzzy Set and Dimensional Analysis. Finally, the applicability of the proposed method is illustrated through numerical examples, and a validation via Spearman correlation and Cronbach's alpha.

The design of the theoretical model of these skills was carried out based on six skills: management in the supply chain, information technologies, quantitative methods, finance, legislation, and soft skills. Its validation was made through the judgment of experts in the area of the supply and logistics chain. The result obtained was a Kappa value of 0.715, a good value. To validate the reliability of the measurement instrument, it was applied to 20 people working in the logistics area. The Cronbach alpha coefficient was used, obtaining a value of 0.928, which allows the reliability of the instrument to be considered excellent.

This context is an ideal technique with complex fuzzy foundation that means to denote multi-dimensional data in a concise. In this framework, criteria weights are evaluated by the SWARA technique, and the ranking of alternatives is determined by the COPRAS method using CIFSs. Further, to illustrate the applicability of the presented technique, an empirical case study of ERP software selection problem is taken. A comparative study and sensitivity analysis is presented to verify the strength of the presented methodology.

It is an extended version of existing fuzzy soft set models that can be used to describe imprecise data in real-world scenarios. e paper seeks to introduce the new concept of spherical fuzzy soft topology de ned on spherical fuzzy soft sets. In this work, we de ne some basic concepts including spherical fuzzy soft basis, spherical fuzzy soft subspace, spherical fuzzy soft interior, spherical fuzzy soft closure, and spherical fuzzy soft boundary. e properties of these de ned set are also discussed and explained with an appropriate examples. Also, we establish certain important results and introduce spherical fuzzy soft separation axioms, spherical fuzzy soft regular space, and spherical fuzzy soft normal space. Furthermore, as an application, a group decision-making algorithm is presented based on the TOPSIS (Technique of Order Preference by Similarity to an Ideal Solution) method for solving the decision-making problems. e applicability of the proposed method is demonstrated through a numerical example. e comprehensive advantages of the proposed work have been stated over the existing methods.
