INVENT Modeling, Simulation, Analysis and Optimization

Abstract: In this paper, a new subsystem-based approach to solve aerospace vehicle energy management issues is described. The goal of this approach is to create an “Energy Optimized Aircraft” that will maximize energy utilization for broad capabilities while minimizing complexity. To support this goal, an advanced modeling and simulation ICD process is established. This process addresses several of the current challenges facing modeling and simulation of large integrated systems.

Modeling and Applications

Abstract: A timely introduction to the latest modeling and simulation techniques Object-oriented modeling is a fast-growing area of modeling and simulation that provides a structured, computer-supported way of doing mathematical and equation-based modeling. Modelica is today’s most promising modeling language in that it effectively unifies and generalizes previous object-oriented modeling languages and provides a sound basis for the basic concepts. Principles of Object-Oriented Modeling and Simulation with Modelica 2.1 introduces the latest methods of object-oriented component-based system modeling and simulation, and provides a tutorial and reference for the latest version of Modelica complete with a comprehensive overview of application model libraries from many domains. Executable examples are included from many areas–physics, mechanics, electrical systems, thermodynamics, flow systems, computer science, concurrent and real-time processes, biology, ecology chemistry, economy, etc. Designed for students, researchers, and engineers familiar with basic programming concepts, the text: Introduces the concepts of physical modeling, object-oriented modeling, and component-based modeling Includes both visual and textual modeling/programming Provides a complete yet informal overview of the Modelica language Demonstrates modeling examples for a wide range of applications Acts as a reference guide for the most commonly used Modelica libraries Features the current version of Modelica 2.1 including some anticipated extentions Its flexible format, comprehensive coverage of the field, and practical focus makes Principles of Object-Oriented Modeling and Simulation with Modelica 2.1 an indispensable teaching tool, a timely reference source for modeling and programming with Modelica, and a valuable hands-on guide for doing physical modeling in a broad range of application areas.

Crowd Simulation Modeling Applied to Emergency and Evacuation Simulations using Multi-Agent Systems

Abstract: In recent years crowd modeling has become increasingly important both in the computer games industry and in emergency simulation. This paper discusses some aspects of what has been accomplished in this field, from social sciences to the computer implementation of modeling and simulation. Problem overview is described including some of the most common techniques used. Multi-Agent Systems is stated as the preferred approach for emergency evacuation simulations. A framework is proposed based on the work of Fangqin and Aizhu with extensions to include some BDI aspects. Future work includes expansion of the model's features and implementation of a prototype for validation of the propose methodology.
