“Applications Reviews” is a guide to accomplished or partial MS/OR applications, cited in articles appearing in many of the major journals of the field. We cover only applications—except for the occasional brief mention of a survey article or special issue—and so do not claim to cover all the best articles in MS/OR. The abstracts are purposely kept short to emphasize breadth of coverage over depth; we try to tell you what modeling approach has been applied to what problem, and if possible the size and character of the improvements achieved as a result.
