The mission of Operations Research is to serve the entire Operations Research (OR) community, including practitioners, researchers, educators, and students. Operations Research, as the flagship journal of our profession, strives to publish results that are truly insightful. Each issue of Operations Research attempts to provide a balance of well-written articles that span the wide array of creative activities in OR. Thus, the major criteria for acceptance of a paper in Operations Research are that the paper is important to more than a small subset of the OR community, contains important insights, and makes a substantial contribution to the field that will stand the test of time.
