Book Description
Avec l'evolution recente des modeles mathematiques vers des simulations informatiques, les formalisations du vivant sont de plus en plus integratives, mixtes et, en un sens, realistes. Plus generalement, les formalisations d'objets complexes deviennent assises sur et non plus seulement traitees par l'infrastructure informatique. Quelle est la veritable portee epistemologique de cette empirie simulee? Comment la distinguer de la creativite proprement interne aux mathematiques dont la philosophie des sciences a deja su rendre compte? En se penchant sur les modeles de plantes, cette enquete historique et epistemologique montre comment une telle evolution bouleverse les epistemologies contemporaines des formalisations et des modeles (dont l'iconoclasme epistemologique si vivace au XXe siecle) en renouvelant d'une part la question des rapports entre mathematiques, calcul, langage informatique et replication, et d'autre part la question de l'integration, dans un objet formel commun, de savoirs disciplinaires distincts.

Book Description
This book analyses the impact computerization has had on contemporary science and explains the origins, technical nature and epistemological consequences of the current decisive interplay between technology and science: an intertwining of formalism, computation, data acquisition, data and visualization and how these factors have led to the spread of simulation models since the 1950s. Using historical, comparative and interpretative case studies from a range of disciplines, with a particular emphasis on the case of plant studies, the author shows how and why computers, data treatment devices and programming languages have occasioned a gradual but irresistible and massive shift from mathematical models to computer simulations.

Book Description
Explores wide-ranging applications of modeling and simulation techniques that allow readers to conduct research and ask "What if?" Principles of Modeling and Simulation: A Multidisciplinary Approach is the first book to provide an introduction to modeling and simulation techniques across diverse areas of study. Numerous researchers from the fields of social science, engineering, computer science, and business have collaborated on this work to explore the multifaceted uses of computational modeling while illustrating their applications in common spreadsheets. The book is organized into three succinct parts: Principles of Modeling and Simulation provides a brief history of modeling and simulation, outlines its many functions, and explores the advantages and disadvantages of using models in problem solving. Two major reasons to employ modeling and simulation are illustrated through the study of a specific problem in conjunction with the use of related applications, thus gaining insight into complex concepts. Theoretical Underpinnings examines various modeling techniques and introduces readers to two significant simulation concepts: discrete event simulation and simulation of continuous systems. This section details the two primary methods in which humans interface with simulations, and it also distinguishes the meaning, importance, and significance of verification and validation. Practical Domains delves into specific topics related to transportation, business, medicine, social science, and enterprise decision support. The challenges of modeling and simulation are discussed, along with advanced applied principles of modeling and simulation such as representation techniques, integration into the application infrastructure, and emerging technologies. With its accessible style and wealth of real-world examples, Principles of Modeling and Simulation: A Multidisciplinary Approach is a valuable book for modeling and simulation courses at the upper-undergraduate and graduate levels. It is also an indispensable reference for researchers and practitioners working in statistics, mathematics, engineering, computer science, economics, and the social sciences who would like to further develop their understanding and knowledge of the field.

Book Description
La Dynamique des Systèmes trouve ses principales applications dans les environnements complexes et mal définis, où interviennent les décisions de l'être humain. Le point de vue de la Dynamique des Systèmes diffère radicalement de celui d'autres techniques appliquées à la construction de modèles de systèmes socio-économiques, tels que l'économétrie basée sur une approche comportementale. L'objectif fondamental de la Dynamique des Systèmes est de comprendre les causes structurelles responsables du comportement du système. La Dynamique des Systèmes permet la construction de modèles après une analyse minutieuse des éléments du système. Cette analyse permet d'extraire la logique interne du modèle et d'essayer de comprendre l'évolution à long terme du système. Il existe une bibliographie détaillée sur la dynamique des systèmes. Ce livre fournit une vision claire et ordonnée de la construction d'un modèle de simulation avec cette technique. Il comprend une modélisation détaillée des systèmes environnementaux, commerciaux, sociaux et physiques. Index 1. Dynamique des Systèmes 1.1. Dynamique des systèmes 1.2.

Book Description
Models and simulations are an important first step in developing computer applications to solve real-world problems. However, in order to be truly effective, computer programmers must use formal modeling languages to evaluate these simulations. Formal Languages for Computer Simulation: Transdisciplinary Models and Applications investigates a variety of programming languages used in validating and verifying models in order to assist in their eventual implementation. This book will explore different methods of evaluating and formalizing simulation models, enabling computer and industrial engineers, mathematicians, and students working with computer simulations to thoroughly understand the progression from simulation to product, improving the overall effectiveness of modeling systems.

Book Description
Master modeling and simulation using Modelica, the new powerful, highly versatile object-based modeling language Modelica, the new object-based software/hardware modeling language that is quickly gaining popularity around the world, offers an almost universal approach to high-level computational modeling and simulation. It handles a broad range of application domains, for example mechanics, electrical systems, control, and thermodynamics, and facilitates general notation as well as powerful abstractions and efficient implementations. Using the versatile Modelica language and its associated technology, this text presents an object-oriented, component-based approach that makes it possible for readers to quickly master the basics of computer-supported equation-based object-oriented (EOO) mathematical modeling and simulation. Throughout the text, Modelica is used to illustrate the various aspects of modeling and simulation. At the same time, a number of key concepts underlying the Modelica language are explained with the use of modeling and simulation examples. This book: Examines basic concepts such as systems, models, and simulations Guides readers through the Modelica language with the aid of several step-by-step examples Introduces the Modelica class concept and its use in graphical and textual modeling Explores modeling methodology for continuous, discrete, and hybrid systems Presents an overview of the Modelica Standard Library and key Modelica model libraries Readers will find plenty of examples of models that simulate distinct application domains as well as examples that combine several domains. All the examples and exercises in the text are available via DrModelica. This electronic self-teaching program, freely available on the text's companion website, guides readers from simple, introductory examples and exercises to more advanced ones. Written by the Director of the Open Source Modelica Consortium, Introduction to Modeling and Simulation of Technical and Physical Systems with Modelica is recommended for engineers and students interested in computer-aided design, modeling, simulation, and analysis of technical and natural systems. By building on basic concepts, the text is ideal for students who want to learn modeling, simulation, and object orientation.
