This unique volume introduces and discusses the methods of validating computer simulations in scientific research. The core concepts, strategies, and techniques of validation are explained by an international team of pre-eminent authorities, drawing on expertise from various fields ranging from engineering and the physical sciences to the social sciences and history. The work also offers new and original philosophical perspectives on the validation of simulations. Topics and features: introduces the fundamental concepts and principles related to the validation of computer simulations, and examines philosophical frameworks for thinking about validation; provides an overview of the various strategies and techniques available for validating simulations, as well as the preparatory steps that have to be taken prior to validation; describes commonly used reference points and mathematical frameworks applicable to simulation validation; reviews the legal prescriptions, and the administrative and procedural activities related to simulation validation; presents examples of best practice that demonstrate how methods of validation are applied in various disciplines and with different types of simulation models; covers important practical challenges faced by simulation scientists when applying validation methods and techniques; offers a selection of general philosophical reflections that explore the significance of validation from a broader perspective. This truly interdisciplinary handbook will appeal to a broad audience, from professional scientists spanning all natural and social sciences, to young scholars new to research with computer simulations. Philosophers of science, and methodologists seeking to increase their understanding of simulation validation, will also find much to benefit from in the text.
Illustrative example problems in continuous system simulation are presented throughout the book, supported by extended case studies from a number of interdisciplinary applications.

This work began when I was appointed as a Technical Director for Modeling and Simulation (M&S) Verification and Validation (V&V) for a major defense system in 2008. It is intended to provide the nuts and bolts of performing M&S V&V in one volume. It is not intended to provide a holistic approach to M&S V&V, as that can be derived from other sources. As such, this book assumes a basic understanding of V&V, including its place in the lifecycle, its purpose and its scope for ensuring the quality of models and simulations. During the process of developing this text, the Simulation Interoperability Standards Organization (SISO) completed SISO-GUIDE-001.2-2013, Guide for Generic Methodology for Verification and Validation (GM-VV) to Support Acceptance of Models, Simulations, and Data, 2 Volumes, June 2013. The guide does serve the purpose not covered by this book. This text provides procedural details for performing V&V. The procedures are static, dynamic and informal.

Implicit in the terminology are the limitations on simulation assessment as well.
For example, if a simulation models a real-world system that does not yet exist,
then we technically cannot validate the simulation. In their text on simulation ...

Helps you ensure that your simulations are appropriate representations of real-world systems. The book concentrates on the differentiation between the assessment of a simulation tool and the verification and validation of general software products. It is a systematic, procedural, practical guide that you can use to enhance the credibility of your simulation models. In addition, it is a valuable reference book and a road map for software developers and quality assurance experts, or as a text for simulation methodology and software engineering courses. This book details useful assessment procedures and phases, discusses ways to tailor the methodology for specific situations and objectives, and provides numerous assessment aids. The reader can use these aids to support ongoing assessments over the entire life cycle of the model.

"The FHWA, Office of Motor Carrier Highway Safety is conducting research to validate the use of low-to mid-cost simulator for commercial driver training, testing and licensing. The primary purpose of the study is to examine how simulator technology, as compared to conventional methods, may facilitate and enhance tractor-trailer driver performance. This report details the proposed research design to conduct the empirical simulator validation study. The research design consists of three distinct parts. Part 1 addresses the forward transfer of training for entry-level drivers. Part 2 is an assessment of the advanced capabilities of the test simulator. Part 3 is a longitudinal study of the drivers that have successfully completed either the truck based or simulator based driver training program and have gone onto earn their Commercial Drivers License. A previous OMCHS report titled, " Commercial Motor Vehicle Simulation Technology To Improve Driver Training, Testing and Licensing Methods Final Report - April 1996," evaluated truck driving simulators in the US and Europe. The report indicated that truck driving simulation was sufficiently mature and recommended that FHWA validate this technology. The Digitran SafeDrive 1000 was recommended as the test bed for the follow on validation study. A copy of the report can be obtained by contacting the National Technical Information Service (703-605-6000 or 1-800-553-6847) and referencing NTIS Publication Number PB96-183405, The validation study will commence in FY 1999. It will start with a reassessment of the commercial marketplace to assure the simulator selected as the test bed for the study reflects the most up to date information and best meets the needs of OMCHS"--Technical report documentation page.

Author: Elson B. Spangler
The California Type Profilograph is presently used by many state transportation agencies to evaluate and accept the ride quality of new Portland Cement Concrete pavements. Although the Profilograph equipment is normally owned by the paving contractor, the state highway agency is often interested in making the same measurements with their own equipment. To meet this need, the Ohio Department of Transportation (Ohio DOT) contracted Surface Dynamics, Inc., to develop a simulation of the California Type Profilograph which uses as its input the profile measurements made with their K.J. Law Profilometer, and has as its output the same output as a McCracken California Type Profilograph which had been used by a paving contractor on an Ohio DOT paving project. In this research project, the output of the computer simulation of the California Type Profilograph compared favorably to the output of the actual McCracken California Type Profilograph on a typical Ohio DOT paving project.

Author: A. V. Gafarian
Statistical validation of simulation models has much interest in military applications. In particular, there is interest in transportation problems during emergency and standard situations. However, collection of suitable data is difficult and almost necessarily is limited to standard situations. Such a situation is examined in this paper. Vehicle traffic on a section of a freeway (expressway) near an on-ramp is simulated by a Monte Carlo model. Ability of the model to represent actual traffic flow is investigated by observing operational systems and making comparisons with results from corresponding simulations. Measures of effectiveness are used that compare statistics for operational systems with values of these properties for corresponding simulations (to see if the difference is significant). Separate comparisons are made for three kinds of statistics: (1) Average travel times for vehicles entering on the freeway; (2) Average travel times for vehicles entering on-ramp; (3) Some averages of velocities. Two phases occur, depending on the data for operational systems. (Author).
