The book "Multi-Criteria Decision Analysis via Ratio and Difference Judgement" by Freerk A. Lootsma offers a comprehensive analysis of decision-making processes considering multiple criteria. It is aimed at decision-makers who evaluate alternative options and express their preferences by estimating ratios of subjective values or differences of corresponding logarithms. The detailed examination of three methods of Multi-Criteria Decision Analysis (MCDA) – the Simple Multi-Attribute Rating Technique (SMART) as well as the additive and multiplicative Analytical Hierarchy Process (AHP) – demonstrates how these approaches overcome the known weaknesses of the original AHP. The book also addresses context-related preference modeling based on psychophysical research and provides numerous case studies from various fields such as higher education administration, healthcare, and environmental assessment. The concluding chapters focus on the development and challenges of MCDA since the late 1970s.
