978-0-470-01509-4 (ISBN)
The popularity of spreadsheets in both business and academia has increased considerably over the past five years. This new edition of a successful textbook will be thoroughly updated to reflect changing practices and technology. This text adopts an active learning approach with the emphasis being placed on the utilization of software tools to help build models. The book’s primary approach is to help the reader put theory into practice. The ‘learn by example’ approach used throughout the book guides the user through the complexities of model building. Every day examples from business and operations management form the basis of the book’s ‘hands on’ development models that help the reader to appreciate Excel’s power and flexibility.
Dr Barlow holds degrees in mathematics, computer science, and mechanical engineering. As well as extensive teaching experience – previously at the Universities of Cape Town, South Africa and Wollongong, Australia – he has held various positions in computer consultancy and the petroleum industry. He has published numerous papers in the areas of computer applications and systems management.
