Available in PDF, EPUB and Kindle. Book excerpt: This book is considered as a monograph but also as a potential textbook for graduate students, focusing on the application of FCMs for modelling and analysing the behaviour of multicomponent systems. In the last two decades, no monograph or textbook has been published on the topic Fuzzy Cognitive Maps (FCM), so this new book is definitely filling a gap in the literature of computational intelligence. The book is built up didactically, the novel results in the field being presented in the way of starting with two real-life case studies, one in the area of waste management, while the other one in modelling bank management systems. In both cases, the book starts with explaining the applied problem and then presenting how the model construction is done and what problems emerge when attempts are made for applying directly earlier results on FCM modelling. In the first case study, the problem of the oversimplification leads to inadequacy of the model, and then it is shown how new, much finer models can be built up based on expert domain knowledge. Then, the new problem of losing transparency and interpretability emerges, and as a solution, a new algorithm family is proposed that reduces FCMs to fewer components, while preserving the essential characteristics of the original model. The second case study raises the problems of stability and sensitivity of FCMs, especially, considering that expert knowledge is often uncertain and subjective. The new results summarised in the book target the questions of how to ascertain whether an FCM is converging to one or several fixed point attractors, whether there is a bifurcation when parameters are changing, etc. Both problems deal with the ultimate question whether the system modelled is stable and sustainable.
Book Synopsis Fuzzy Cognitive Maps by : Michael Glykas
Download or read book Fuzzy Cognitive Maps written by Michael Glykas and published by Springer. This book was released on 2010-09-07 with total page 436 pages. Available in PDF, EPUB and Kindle. Book excerpt: This important edited volume is the first such book ever published on fuzzy cognitive maps (FCMs). Professor Michael Glykas has done an exceptional job in bringing together and editing its seventeen chapters. The volume appears nearly a quarter century after my original article “Fuzzy Cognitive Maps” appeared in the International Journal of Man-Machine Studies in 1986. The volume accordingly reflects many years of research effort in the development of FCM theory and applications—and portends many more decades of FCM research and applications to come. FCMs are fuzzy feedback models of causality. They combine aspects of fuzzy logic, neural networks, semantic networks, expert systems, and nonlinear dynamical systems. That rich structure endows FCMs with their own complexity and lets them apply to a wide range of problems in engineering and in the soft and hard sciences. Their partial edge connections allow a user to directly represent causality as a matter of degree and to learn new edge strengths from training data. Their directed graph structure allows forward or what-if inferencing. FCM cycles or feedback paths allow for complex nonlinear dynamics. Control of FCM nonlinear dynamics can in many cases let the user encode and decode concept patterns as fixed-point attractors or limit cycles or perhaps as more exotic dynamical equilibria. These global equilibrium patterns are often “hidden” in the nonlinear dynamics. The user will not likely see these global patterns by simply inspecting the local causal edges or nodes of large FCMs.

This book was released on 2013-12-02 with total page 411 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fuzzy Cognitive Maps (FCM) constitute cognitive models in the form of fuzzy directed graphs consisting of two basic elements: the nodes, which basically correspond to “concepts” bearing different states of activation depending on the knowledge they represent, and the “edges” denoting the causal effects that each source node exercises on the receiving concept expressed through weights. Weights take values in the interval [-1,1], which denotes the positive, negative or neutral causal relationship between two concepts. An FCM can be typically obtained through linguistic terms, inherent to fuzzy systems, but with a structure similar to the neural networks, which facilitates data processing, and has capabilities for training and adaptation. During the last 10 years, an exponential growth of published papers in FCMs was followed showing great impact potential. Different FCM structures and learning schemes have been developed, while numerous studies report their use in many contexts with highly successful modeling results. The aim of this book is to fill the existing gap in the literature concerning fundamentals, models, extensions and learning algorithms for FCMs in knowledge engineering. It comprehensively covers the state-of-the-art FCM modeling and learning methods, with algorithms, codes and software tools, and provides a set of applications that demonstrate their various usages in applied sciences and engineering.

This book was released on 2003-01-01 with total page 213 pages. Available in PDF, EPUB and Kindle. Book excerpt: In a world of chaotic alignments, traditional logic with its strict boundaries of truth and falsity has not imbued itself with the capability of reflecting the reality. Despite various attempts to reorient logic, there has remained an essential need for an alternative system that could infuse into itself a representation of the real world. Out of this need arose the system of Neutrosophy (the philosophy of neutralities, introduced by FLORENTIN SMARANDACHE), and its connected logic Neutrosophic Logic, which is a further generalization of the theory of Fuzzy Logic. In this book we study the concepts of Fuzzy Cognitive Maps (FCMs) and their Neutrosophic analogue, the Neutrosophic Cognitive Maps (NCMs). Fuzzy Cognitive Maps are fuzzy structures that strongly resemble neural networks, and they have powerful and far-reaching consequences as a mathematical tool for modeling complex systems. Neutrosophic Cognitive Maps are generalizations of FCMs, and their unique feature is the ability to handle indeterminacy in relations between two concepts thereby bringing greater sensitivity into the results. Some of the varied applications of FCMs and NCMs which has been explained by us, in this book, include: modeling of supervisory systems; design of hybrid models for complex systems; mobile robots and in intimate technology such as office plants; analysis of business performance assessment; formalism debate and legal rules; creating metabolic and regulatory network models; traffic and transportation problems; medical diagnostics; simulation of strategic planning process in intelligent systems; specific language impairment; web-mining inference application; child labor problem; industrial relations: between employer and employee, maximizing production and profit; decision support in intelligent intrusion detection system; hyper-knowledge representation in strategy formation; female infanticide; depression in terminally ill patients and finally, in the theory of community mobilization and women empowerment relative to the AIDS epidemic.

Download or read book Fuzzy Cognitive Maps written by Philippe J. Giabbanelli and published by Springer. This book was released on 2024-02-05 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book starts with the rationale for creating an FCM by contrast to other techniques for participatory modeling, as this rationale is a key element to justify the adoption of techniques in a research paper. Fuzzy cognitive mapping is an active research field with over 20,000 publications devoted to externalizing the qualitative perspectives or “mental models” of individuals and groups. Since the emergence of fuzzy cognitive maps (FCMs) back in the 80s, new algorithms have been developed to reduce bias, facilitate the externalization process, or efficiently utilize quantitative data via machine learning. It covers the development of an FCM with participants through a traditional in-person setting, drawing from the experience of practitioners and highlighting solutions to commonly encountered challenges. The book continues with introducing principles of simulations with FCMs as a tool to perform what-if scenario analysis, while extending those principles to more elaborated simulation scenarios where FCMs and agent-based modeling are combined. Once an FCM model is obtained, the book then details the analytical tools available for practitioners (e.g., to identify the most important factors) and provides examples to aid in the interpretation of results. The discussion concerning relevant extensions is equally pertinent, which are devoted to increasing the expressiveness of the FCM formalism in problems involving uncertainty. The last four chapters focus on building FCM models from historical data. These models are typically needed when facing multi-output prediction or pattern classification problems. In that regard, the book smoothly guides the reader from simple approaches to more elaborated algorithms, symbolizing the noticeable progress of this field in the last 35 years. Problems, recent references, and functional codes are included in each chapter to provide practice and support further learning from practitioners and researchers.

Book Synopsis Developments in Fuzzy Cognitive Maps and Their Applications to Enterprise Resource Planning Readiness Assessment by : Sadra Ahmadi
Download or read book Developments in Fuzzy Cognitive Maps and Their Applications to Enterprise Resource Planning Readiness Assessment written by Sadra Ahmadi and published by . This book was released on 2014 with total page 492 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fuzzy Cognitive Maps (FCMs) have been widely used for modelling and analysing causal relationships and feedback between components of a complex system. This research develops two efficient and effective algorithms for learning FCMs. This research also develops a structured FCM-based methodology for assessing, managing and planning change readiness for implementing a complex information system involving many interrelated readiness-relevant factors.Modelling and analysing a system using the FCM technique can be done by using either experts' knowledge or historical data about the system. This research has two main objectives: (1) developing new, accurate and fast algorithms for analysing historical data to develop FCM models, and (2) developing a FCM-based methodology using experts' knowledge for analysing and managing the readiness of an organisation for implementing a complex information system.To achieve the first objective, this research investigates whether the new forms of evolutionary algorithms provide a faster and more accurate algorithm for automated FCM learning using historical data. Two new types of fast and accurate FCM learning algorithms are developed by using two evolutionary optimisation algorithms called the Cultural Algorithm (CA) and the Imperialist Competitive Algorithm (ICA). The two new FCM learning algorithms resulted from using these two algorithms are the Cultural Learning Algorithm (CLA) and the Imperialist Competitive Learning Algorithm (ICLA) respectively. Comparing these two new FCM learning algorithms with many existing and well-known learning algorithms, such as Real Coded Genetic Algorithm (RCGA) and divide and conquer RCGA, shows that in most cases they outperform existing algorithms in terms of accuracy and speed. The experimental comparison between CLA and ICLA also shows that the accuracy of CLA is slightly better than ICLA, whereas ICLA is more efficient than the CLA.To achieve the second objective, this research addresses two issues: (1) how causal relationships between interrelated readiness-relevant factors or activities can be modelled for assessing an organisation's readiness for a major change, and (2) how an organisation can develop the most cost effective plan for improving the readiness. This research addresses these two issues in the context of a new Enterprise Resource Planning (ERP) system implementation.To address the first issue, a structured FCM-based methodology for managing interrelated readiness-relevant factors or activities to implement a significant change is developed. The methodology can (1) identify the readiness-relevant factors, (2) determine how these factors influence each other, (3) assess how these factors contribute to the overall readiness, (4) cluster the factors into manageable groups and (5) prioritise the factors according to their causal interrelationships to find the most influential factors for allocating readiness improvement management effort. In addition, based on the contribution of the factors on the overall readiness and their interrelationships, the factors can be categorised into four management zones for effective allocation of limited management efforts.To address the second issue, an FCM-based problem solving methodology is developed to find the most cost effective plan for improving the readiness. This methodology finds the best readiness improvement plan as a multi objective trade-off between the two objectives of readiness maximisation and cost minimisation using the Nondominated Sorting Genetic Algorithm II evolutionary algorithm. The result of solving this problem is a set of optimal improvement plans from which the best plan for meeting an organisation's specific needs can be determined.This research has made significant methodological and practical contributions to both FCM and ERP research. As a methodological contribution to FCM research, this research develops two new, effective, and efficient automated FCM learning algorithms. As a methodological contribution to ERP research, this research develops a structured readiness management methodology with methodological advances including (1) modelling causal relationships between interrelated ERP readiness-relevant factors or activities, (2) reflecting the imprecise nature of the readiness assessment process, (3) prioritising readiness-relevant factors based on their causal relationships with other factors, (4) reducing the complexity of the readiness assessment model by clustering factors into manageable groups, and (5) analysing the readiness assessment model to find the most cost effective areas and factors for improving the overall readiness.As practical contribution to ERP research, this research shows how the new structured readiness management methodology can help an organisation (1) identify the main areas required for management focus and (2) analyse the readiness-relevant factors to determine the individual factors which should be improved for achieving the highest readiness improvement. These are significant contributions to the practice of ERP implementation. The methodology developed and the outcomes produced in this research are valuable for an organisation to effectively manage its readiness relevant factors or activities during the pre-implementation stage of an ERP system.

Book Synopsis Assessing and Supporting the Use of Fuzzy Cognitive Maps to Simulate Complex Phenomena by : Eric Lavin
Download or read book Assessing and Supporting the Use of Fuzzy Cognitive Maps to Simulate Complex Phenomena written by Eric Lavin and published by . This book was released on 2018 with total page 155 pages. Available in PDF, EPUB and Kindle. Book excerpt: To study complex phenomena, modelers have used a wide variety of modeling techniques (e.g. agent-based modeling). While these are powerful and useful modeling methods, they are not perfect. To improve our models of complex problems, we need to apply methods that handle uncertainty such as Fuzzy Cognitive Maps (FCM). This thesis will show that while we use simulation models to evaluate complex phenomena, we do not apply FCMs in these evaluations very often. While they are commonly used in participatory modeling to handle uncertainty in small models, this thesis proposes and evaluates a new method to handle uncertainty in much larger models using FCMs. Specifically, we use parallel Design of Experiments (DoE) and demonstrate that previously published large models can be simplified. We will present a design of experiments which will extend the ability of Fuzzy Grey Cognitive Maps (FGCM) to better handle uncertainty, and identify the main factors that determine the simulation output. We also explore an approximation to allow for execution within a time limit. Beyond handling uncertainty, this thesis will examine whether we need to run several simulations to compare different FCMs, or if we can just compare their structures as graphs. This work is limited by the small number of FGCMs currently published. In the future, our work can be used to create a hybrid model for agent-based models with FCMs, or to identify the rules necessary to create a heterogeneous population of agents.

This book was released on 2014 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book the authors for the first time have merged vertices and edges of lattices to get a new structure which may or may not be a lattice but is always a graph. This merging is done for graph too which will be used in the merging of fuzzy models. Further merging of graphs leads to the merging of matrices; both these concepts play a vital role in merging the fuzzy and neutrosophic models. Several open conjectures are suggested.
