Dr. Alan Barnard is recognized as one of the leading TOC Experts in the world. For the last 15 years, he has worked with Dr. Eli Goldratt on developing new TOC knowledge and leading TOC analysis and implementations for typically large and complex organizations from both the private sector and the public sector. He has applied TOC to achieve his personal goal of helping organizations and individuals identify and unlock their inherent potential.
Dr. Barnard is CEO of Goldratt Research Labs, Director of Goldratt Group Africa, Chairman of Realization Africa, Chairman of African Phosphates and Chairman of The Odyssey Institute.
He was a founding board member and chairman of TOCICO (Theory of Constraints Certification Organization) from 2003-2005, currently serves as chair for the TOCICO Business Strategy Certification committee and received the TOCICO Lifetime Membership award in 2006.
Jaco-Ben is an industrial engineer with extensive experience in Simulation modeling to determine the potential performance of systems and the impact of changing the rules and other conditions on system performance. He has worked with Dr. Alan Barnard to develop a number of Business Simulation models and Apps including Goldratt’s Dice Game and Goldratt Mining Supply Chain Simulation Model that is available in the IOS and OS X Mac App stores. At GRL, Jaco-Ben is responsible for Technology and Simulation Projects.
Ben is passionate about simulation and is a recognized thought leader in the community. He delivers innovative keynote speeches, co-hosts a simulation podcast and writes a blog on all things simulation. He joined Goldratt Research Labs in 2018 focusing on productionising simulation models for a broader audience. Ben started his passion for simulation during his PhD in Complex Systems Simulation at the University of Southampton (UK). After that, he worked with decisionLab, a boutique simulation consulting firm in London for three years. Before joining Goldratt, he worked as a simulation consultant with McKinsey & Company, Inc., predominantly in their supply chain and mining practices.
Andrey is one of the leading experts in applying simulation and data analysis techniques to solve complex and challenging business tasks, especially in logistics, inventory management and production. Andrey has 5 years of experience in business consulting and 7 years of experience in practical simulation. In 2011 Andrey was awarded a Ph.D. degree in simulation. Andrey is an expert in using AnyLogic, the preferred simulation modeling software used by Goldratt Research Labs and has worked with his experienced simulation and data analytics team with Dr. Alan Barnard on a few large and complex simulation projects to show for example the benefits that Theory of Constraints can bring when applied, not only to links within a supply chain, but to optimize the whole supply chain.
