Resumo: A teoria de grafos é uma importante área da programação matemática, tendo um importante papel em áreas tais como engenharia e pesquisa operacional. Em particular, ela fornece ferramentas para tratar problemas de redes (tais como: alocação, caminho mÃnimo, fluxo máximo, etc.), que têm aplicações em diversas subáreas da engenharia (por exemplo: telecomunicações, transporte, manufatura, etc.). Estas aplicações podem, entretanto, possuir incertezas em seus parâmetros ou em sua estrutura. Baseado nisto, este trabalho trata de algumas importantes aplicações de problemas em grafos com incertezas em seus parâmetros ou estruturas e propõe algoritmos para encontrar suas soluções. As aplicações estudadas são: problemas de caminho mÃnimo, problemas de fluxo máximo, problemas de fluxo de custo mÃnimo e problemas de coloração de grafos. As incertezas são modeladas por meio da teoria dos conjuntos fuzzy, que tem sido aplicada com sucesso em problemas com incertezas e imprecisões
Abstract: The graph theory is an important area of mathematical programming, it has an important role in fields such as engineering and operational research. In particular, it provides the tools to tackle network problems (e.g. allocation, shortest path, maximum flow, etc), which have applications in several sub areas of engineering (e.g. telecommunications, transportation, manufacturing, etc). These applications can, however, possess uncertainties in their parameters or in their structure. Based on that, this work addresses some important applications of graph problems with uncertainties in their structure or parameters and proposes algorithms to find the solution to them. The applications studied are: shortest path problems, maximum flow problems, minimum cost flow problems and graph coloring problems. The uncertainties are modeled by means of the fuzzy sets theory, which has been successfully applied to problems with uncertainties and vagueness

Com o passar dos dias os sistemas de software e hardware evoluem e ficam cada vez mais complexos e sofisticados. Como consequência especificar esses sistemas se torna uma tarefa difícil e trabalhosa. No sentido de assegurar certas propriedades de um sistema, este deve ser especificado por intermédio de uma linguagem que ofereça métodos de análise. Para realizar essas especificações temos diversas técnicas e metodologias, onde algumas técnicas que são disponíveis no mercado podem gerar resultados diferentes do que o especificado e esperado. Para realizar a correção deste problema, tem-se a necessidade de se utilizar métodos formais para gerar a especificação e verificação de sistemas. Sistemas que utilizam métodos formais são especificados formalmente através de um modelo matemático. Gramática de Grafos é uma linguagem formal bastante propícia para especificar sistemas complexos, é interessante o uso delas, pelo fato de possuírem inúmeras técnicas para a verificação e especificação de sistemas que são representadas nesta linguagem, além do que, elas possuem um layout gráfico, que as torna bastante intuitivas, por isso elas são uma linguagem de fácil entendimento. Gramática de Grafos Fuzzy são obtidas através da generalização das gramáticas de grafos, elas são constituídas por vértices e arestas com valores de pertinência associados, dentro do intervalo 0 e 1. Devido a inexistência de técnicas e ferramentas de análise para gramática de grafos fuzzy, o seu uso ainda é bastante restrito. Uma maneira de permitir a análise de sistemas especificados em gramática de grafos fuzzy é através da extensão das abordagens existentes para gramática de grafos, adicionando os conceitos de pertinência aos componentes dos grafos e para isso foi necessário definir gramáticas de grafos fuzzy tipados. Já existe uma abordagem relacional para gramática de grafos que permite o uso dos provadores de teoremas da ferramenta Rodin, utilizando a linguagem Event-B. Desta forma, a proposta deste trabalho é estender essa abordagem de gramática de grafos adicionando os conceitos fuzzy para permitir utilizar a mesma abordagem para analisar gramática de grafos fuzzy, surgindo assim um método de análise para esse tipo de gramática.
With the passing of days software and hardware systems evolve and become increasingly sophisticated and complex. As a consequence, specifying these systems becomes a difficult and laborious task. In order to ensure certain properties of a system, it must be specified through a language that offers methods of analysis. To realize these specifications we have several techniques and methodologies, where some techniques that are available in the market can generate different results than the specified and expected. To perform the correction of this problem, there is the need of using formal methods for generate the specification and verification systems. Systems that use formal methods are formally specified through a mathematical model. Grammar Graphs is a very suitable to specify complex systems formal language, is interesting to use them because they have innumerable techniques for the verification and specification of systems that are represented in this language, besides that, they have a graphical layout, which makes them very intuitive, so they are an easy-to-understand language. Fuzzy graph grammars are obtained through the generalization of graph grammars, they are constituted by vertices and edges with associated membership values within the interval 0 and 1. Due to the inexistence of techniques and analysis tools for fuzzy graph grammars, its use is still quite restricted. One way to allow the analysis of systems specified in fuzzy graphs grammars is the extension of existing approaches for graphs grammars, adding the concepts of pertinence to the components of graphs and for this it was necessary to define fuzzy graph grammars typed. There is already a relational approach to graph grammar that allows the use of the theorems of the Rodin tool using the language Event-B. In this way, the purpose of this work is to extend this approach of grammars of graphs by adding the fuzzy concepts to allow to use the same approach to analyze fuzzy graphs grammars, thus appearing a method of analysis for this type of grammar.

Full textThis thesis addresses the problem of lack of efficient computational tools for graph based structural pattern recognition approaches and proposes to exploit computational strength of statistical pattern recognition. It has two fold contributions. The first contribution is a new method of explicit graph embedding. The proposed graph embedding method exploits multilevel analysis of graph for extracting graph level information, structural level information and elementary level information from graphs. It embeds this information into a numeric feature vector. The method employs fuzzy overlapping trapezoidal intervals for addressing the noise sensitivity of graph representations and for minimizing the information loss while mapping from continuous graph space to discrete vector space. The method has unsupervised learning abilities and is capable of automatically adapting its parameters to underlying graph dataset. The second contribution is a framework for automatic indexing of graph repositories for graph retrieval and subgraph spotting. This framework exploits explicit graph embedding for representing the cliques of order 2 by numeric feature vectors, together with classification and clustering tools for automatically indexing a graph repository. It does not require a labeled learning set and can be easily deployed to a range of application domains, offering ease of query by example (QBE) and granularity of focused retrieval
Slama, Olfa. "Flexible querying of RDF databases : a contribution based on fuzzy logic." Thesis, Rennes 1, 2017. http://www.theses.fr/2017REN1S089/document.
Full textThis thesis concerns the definition of a flexible approach for querying both crisp and fuzzy RDF graphs. This approach, based on the theory of fuzzy sets, makes it possible to extend SPARQL which is the W3C-standardised query language for RDF, so as to be able to express i) fuzzy user preferences on data (e.g., the release year of an album is recent) and on the structure of the data graph (e.g., the path between two friends is required to be short) and ii) more complex user preferences, namely, fuzzy quantified statements (e.g., most of the albums that are recommended by an artist, are highly rated and have been created by a young friend of this artist). We performed some experiments in order to study the performances of this approach. The main objective of these experiments was to show that the extra cost due to the introduction of fuzziness remains limited/acceptable. We also investigated, in a more general framework, namely graph databases, the issue of integrating the same type of fuzzy quantified statements in a fuzzy extension of Cypher which is a declarative language for querying (crisp) graph databases. Some experimental results are reported and show that the extra cost induced by the fuzzy quantified nature of the queries also remains very limited

Resumo: A teoria dos grafos é comumente utilizada na área da engenharia para resolver problemas que podem ser representados na forma de redes. Dentre diversos problemas abordados, o problema de fluxo multiproduto é um dos que também podem ser modelados por grafos. Este trabalho apresenta uma proposta de solução para o problema de fluxo multiproduto fuzzy. O problema foi modelado através de um grafo, cujos nós representam pontos de oferta e demanda de produtos, os quais trafegam pelos arcos da rede. O algoritmo proposto visa encontrar soluções factiveis e boas para o problema de fluxo multiproduto fuzzy em redes com incertezas nos custos e capacidades, contendo múltiplas origens e múltiplos destinos. As incertezas são modeladas por meio da teoria dos conjuntos fuzzy, que tem sido aplicada com sucesso em problemas com incertezas.
Abstract: The graph theory is commonly used in the area of engineering to solve problems that can be represented in the form of nets. Among several problems, the multicommodity flow problem is one that can be modeled by graphs. This work presents an approach for solving the fuzzy multicommodity flow problem. The problem was modeled through a graph whose nodes represent points of supply and demand of commodities, which pass through arcs of the network. Our algorithm aims to find a set of good feasible solutions for the fuzzy multicommodity flow problem in networks with uncertainties in the costs and capacities, containing multiple origins and multiple destinations. The uncertainties are modeled by means of the fuzzy sets theory, which has been successfully applied to problems with uncertainties.
