“…The concept of a Fuzzy set was introduced in 1965 by Lotfi A. Zadeh. It comprises ambiguous situations, which cannot be processed through the computational logic based on Boolean logic (Marques et al, 2005).…”

Aid application multicriteria the decision based on AHP Method and Fuzzy Logic in commercial land selection

2019

The objective of this article is to select land for commercial buildings in Rio de Janeiro city using multiple criteria decision-making techniques. The techniques used were based on the Analytic Hierarchy Process (AHP) and Fuzzy Logic methods. These methods were chosen because of functionality, flexibility and great application in engineering problems for decision making involving multiple criteria. Its application was made through an opinion survey with expert builders, where 6 (six) factors for evaluation were selected in 10 (ten) commercial land alternatives. For the analytical operation of the methods, the software used were: Super Decisions and MATLAB®, respectively for each method, presenting the factors classified, in order of priority, in the selection of land, and ranking of the alternatives according to the defined scenario, facilitating in this way the process of selection of land for buildings, establishing a scientific way for the decision process.

“…The first step is fuzzification of each variable. This is a stage in which the antecedents of the "IF-THEN" rules and the rules themselves are detailed, that is; variables along with their rules are transformed into linguistic variables to bring degrees of relevance of an object into the set fuzzy correlation (Marques et al, 2005).…”

“…Therefore, in these cases, Fuzzy Logic provides a relatively easy approach to modeling the decision-making process (10) . The use of Fuzzy Logic may be a path for the development of methods to generate an accurate diagnosis, by supporting the expert in establishing his decision and even to attribute weight to each rule that uses this process (11) .…”

RESUMOO objetivo é propor a Lógica Fuzzy para reconhecimento de padrões de conforto de pessoas submetidas a uma tecnologia de cuidar em Enfermagem por apresentarem pênfigo vulgar, uma doença cutâneo-mucosa rara que acomete principalmente adultos. A proposta aplicável em métodos experimentais com sujeitos submetidos à comparação quali-quantitativa (taxonomia/pertinência) do padrão de conforto antes e depois da intervenção. Requer o registro em escala cromática correspondente à intensidade de cada atributo: dor; mobilidade e comprometimento da autoimagem. As regras Fuzzy estabelecidas pela máquina de inferência definem o padrão de conforto em desconforto máximo, mediano e mínimo, traduzindo a eficácia dos cuidados de Enfermagem. Apesar de pouco utilizada na área de Enfermagem, essa lógica viabiliza pesquisas sem dimensionamento a priori do número de sujeitos em função da estimação de parâmetros populacionais. Espera-se avaliação do padrão de conforto do cliente com pênfigo diante da tecnologia aplicada de forma personalizada, conduzindo a avaliação global. DESCRITORES Cuidados de enfermagem Dermatologia Pênfigo Lógica Fuzzy ABSTRACTThe objective was to propose the use of Fuzzy Logic for recognition of comfort patterns in people undergoing a technology of nursing care because of pemphigus vulgaris, a rare mucocutaneous disease that affects mainly adults. The proposal applied experimental methods, with subjects undergoing a qualitative-quantitative comparison (taxonomy/relevance) of the comfort patterns before and after the intervention. A record of a chromatic scale corresponding to the intensity of each atribute was required: pain, mobility and impaired self-image. The Fuzzy rules established by an inference engine set the standard for comfort in maximum, median and minimum discomfort, reflecting the effectiveness of nursing care. Although rarely used in the area of nursing, this logic enabled viable research without a priori scaling of the number of subjects depending on the estimation of population parameters. It is expected to evaluate the pattern of comfort in the client with pemphigus, before the applied technology, in a personalized way, leading to a comprehensive evaluation.

“…It can also be used in the development of decision-making models for nurses who use nursing knowledge considering the nursing process, the complexity of the context, and the degree of intensity of nurse/patient interactions (23) , support for decisionmaking concerning amniotomy in primiparae pregnant woman (24) , and the differential nursing diagnosis of alterations of urinary elimination (25) .…”

“…It can be used to model the basis of algorithm rules, capturing the knowledge of experts and dealing with uncertainty (14) , characterize the variables of a system with fuzzy sets (15)(16) , administer databases with the opinions of experts (17) , classify responses detected by systems (19)(20) , detect and remove data that do not reflect a real situation, and follow-up trends of parameter evolution (21) . It can also be applied to model concepts and uncertainty expressed in linguistic (23) terms in the development of models because fuzzy logic allows the use of natural language and expressions such as "always", "frequently", "sometimes", "rarely" or "never", thus aiding in the decision-making process of nurses in the face of an intervention (24) or diagnosis (25) .…”

This study conducted an integrative review investigating how fuzzy logic has been used in research with the participation of nurses. The article search was carried out in the CINAHL, EMBASE, SCOPUS, PubMed and Medline databases, with no limitation on time of publication. Articles written in Portuguese, English and Spanish with themes related to nursing and fuzzy logic with the authorship or participation of nurses were included. The final sample included 21 articles from eight countries. For the purpose of analysis, the articles were distributed into categories: theory, method and model. In nursing, fuzzy logic has significantly contributed to the understanding of subjects related to: imprecision or the need of an expert; as a research method; and in the development of models or decision support systems and hard technologies. The use of fuzzy logic in nursing has shown great potential and represents a vast field for research.Descriptors: Nursing; Fuzzy Logic; Review Literature as Topic. 1 Paper extracted from Master's Thesis "Desenvolvimento e avaliação de um programa computacional baseado em lógica fuzzy para verificação da acurácia diagnóstica de estudantes de enfermagem" presented to Programa de Pós Graduação, Universidade Estadual Enfermagem e lógica fuzzy: uma revisão integrativaEste estudo teve como objetivo realizar revisão integrativa, investigando como a lógica fuzzy tem sido utilizada em pesquisas com participação de enfermeiros.

A amostra final foi de 21 artigos, de oito países. Para análise, os artigos foram distribuídos nas categorias: teoria, método e modelo. Na enfermagem, a lógica fuzzy tem contribuído significativamente para a compreensão de temas relativos à imprecisão ou à necessidade do especialista, como método de pesquisa e no desenvolvimento de modelos ou sistemas de apoio à decisão e de tecnologias duras.O uso da lógica fuzzy, na enfermagem, tem demonstrado grande potencial e representa vasto campo para pesquisas.Descritores: Enfermagem; Lógica Fuzzy; Literatura de Revisão como Assunto.
