Operations Research conducts single-blinded reviews, meaning that the authors are ‘blind’ to the identity of the reviewers but reviewers are not blind to the author names. It is commonly considered a theory of meaning which states that “we mean by any concept nothing more than a set of operations; the concept is synonymous with the corresponding set of operations” (Bridgman 1927, 5).
