Sandra Ekşioglu is an Associate Professor at Clemson University (CU), in the Department of Industrial Engineering. Her research is focused in the area of Operations Research (OR). She uses OR tools to model and solve large scale supply chain design and management, logistics management and transportation-related problems. Sandra’s research on biofuel supply chain has resulted on a number of innovative models and solution algorithms that improve the performance of this supply chain. She received the NSF CAREER Award in support of this research. In 2012 Sandra was induced to Mississippi State University (MSU), Bagley College of Engineering Academy of Ditinguished Teachers; and in 2015 she received the ASEE-SE Mid-Career Teaching Award. Sandra has been teaching the Information Systems for Industrial Engineers class at MSU and the Decision Support Systems class at CU for several years. These classes teaches students how to build Spreadsheet-Based Decision Support Systems. Sandra used the feedback and comments from students to make valuable additions and modifications to this new edition of the book.

Michelle M.H. Şeref

Michelle Şeref received a Ph.D. in Operations Management in 2009, from the University of Florida, where she also earned Master's and Bachelor's degrees in Industrial and Systems Engineering. During her Master's program, she co-authored the textbook Developing Decision Support Systems using Excel and VBA, also developing extensive course materials and DSS case studies. Dr. Seref has taught DSS-related courses using Excel and VBA in both engineering and business curricula at the University of Florida and Virginia Tech for several years. She has also led several workshops and tutorials at national and international conferences on developing DSS applications using Excel and VBA. Dr. Seref’s Ph.D. dissertation focused on Supply Chain Management Decisions under Various Marketing Strategies, including advance sales inventory management and new product development pricing and timing decisions. Her current research area is in Decision Analytics, with a particular focus in Computational Rhetoric and in Qualitative Factor Analysis. Dr. Seref's research offers a new perspective by combining her background in operations management and decision support systems with qualitative analysis methods as a way of enriching decision science models.
