"This book on sensitivity analysis by Mariia Kozlova and Julian Scott Yeomans summarizes the state-of-the-art method for computational model analysis, the revolutionary Simulation Decomposition (SimDec). For readers like me working in the general areas of modelling, optimization and machine learning, I find this book extremely useful because it essentially has everything about SimDec in one package, which makes it an effective tool to do global sensitivity analysis. The results are easy to understand, with colorful visualization, uncertainty quantification, and a wide spectrum of diverse applications. In addition, the open-source SimDec software with code packages in Python, R, Julia and Matlab will revolutionize the ways for training next-generation scientists and practitioners to do the right kind of sensitivity analysis so as to figure out the most influential factors correctly and to support more informed decision-making."Xin-She Yang, Reader at Middlesex University London, Fellow of the Institute of Mathematics and its Applications (FIMA), UK"Simulation decomposition is an incredibly powerful technique that allows researchers and engineers to identify key factors influencing the performance of a system and make targeted improvements. This book provides a simple and accessible guide to understand and apply the technique to practical problems. The accompanied open-source SimDec code is the key to enable the reader to quickly learn and apply the method."Leifur Leifsson, Associate Professor, School of Aeronautics and Astronautics, Purdue University, USA"Simulation Decomposition methodology, a “Monte Carlo”- based computational algorithm, is quickly becoming a game-changer in the world of engineering, industry, and finance. In this newly published book, Julian Scott Yeomans and Mariia Kozlova explore the importance of this method in providing an accurate and detailed holistic picture of the behavior of complex systems. The book delves into the real-life applications of Simulation Decomposition, highlighting its effectiveness in optimizing processes and improving product designs. Through detailed case studies and insights from industry experts, readers will gain a thorough understanding of this powerful methodology and its potential for transforming the way we approach complex systems."Kambiz Vatan-Abadi, Chief Innovation Officer, CI Financial, Canada"SimDec is an ingenious way to tame the combinatorial complexity of systems’ behavior in real-world decision making. Its deceptively simple approach visually reveals the hidden factors that materially impact an uncertain outcome. This new method for determining sensitivity indices seems a hidden gem. Its transparency is invaluable to practitioners. Credit is also due to the authors for making an otherwise challenging topic most entertaining and accessible to practitioners. SimDec’s ease-of-use should make it the de facto standard for data analysis in industrial, engineering, and scientific environments."Kalyan Moy Gupta PhD, Founder and Vice President of Research, Knexus Research, Washington DC, USA"Black box functions with uncertain inputs are used to encode knowledge in many areas of science, engineering and commerce. The challenge is to get that knowledge back out for the benefit of users. The customary approaches focus on subtle mathematics and expensive computations. This book presents SimDec, which produces interpretable graphical representations that support discussions and discovery."Art Owen, Max H. Stein Professor of Statistics, Stanford University, USA"The fusion of sensitivity analysis with uncertainty analysis through SimDec, as presented in this book, marks a watershed moment for business professionals and GenAI developers alike. It's a guidebook for those who dare to challenge the status quo, offering not just insights but a comprehensive toolkit for transformative decision-making. A testament to the power of interdisciplinary collaboration and open-source innovation in shaping the future of technology. Essential reading for leaders driving innovation in uncertain times."Anferny Chen, CEO and Founder, Dataraction/DotsLive.Com, Canada"This book articulates the SimDec method for global sensitivity analysis by combining a novel visual uncertainty analysis approach with the discriminatory capabilities of a newly-created technique for calculating sensitivity indices. The real beauty of SimDec is that it can be straightforwardly applied to virtually any field of data analysis, irrespective of the mathematical sophistication of the user. I have been working with system dynamics, optimization, stochastic programming, and other analytical approaches for over three decades. One regret I now have is that there was no SimDec procedure in existence at the time to support these activities."Gordon Huang, Canada Research Chair & Professor of Environmental Systems Engineering, University of Regina, Canada
