Webpresent a greedy randomized adaptive search procedure (GRASP) for the job shop scheduling problem. Our interest in studying a new heuristic for a problem for which many e cient heuristics have been proposed is motivated by several observations. GRASP has been applied with success to a number of scheduling problems [4,5,12{14,17,18,26, 29,35,36,41].
