These articles are less technical in nature and aimed primarily at graduate students and practicing researchers. Technical articles, written as 'breakouts' from the advanced articles, provide more detailed discussions of key concepts addressed in the reviews.Ĭase studies/biographical sketches/historical interludes provide an opportunity to present successful and/or interesting examples of operations research/management science methodology in practice or in historical contexts. Advanced articles, aimed at graduate students and researchers, review key areas of research in a citation-rich format similar to that of leading review journals. Introductory articles provide a broad and moderately technical treatment of core topics at a level suitable for advanced undergraduate students as well as scientists without a strong background in the field. This multi-volume encyclopedia is organized alphabetically and contains four levels of articles (Introductory, Advanced, Technical, and Case Studies/Historical Interludes) designed to make its content useful and accessible to the widest possible readership.
