| dc.description.abstract | This study deals with a job allocation and scheduling problem of batch processing ovens belonging to a factory that manufactures welding electrodes. Each electrode type may not be heated on all of the ovens. Besides, there exists a priority order of ovens for each electrode type. The other inputs are; work order amounts of electrodes, the ready times, heating times, cooling down times, and the capacity of each oven with respect to the electrode types. The work orders with the same heating time may be heated simultaneously without exceeding the oven capacity. For the defined problem, an integer programming model is developed. The objective function is to assign the work orders to the preferred ovens as possible and to maximize the utilization rates of ovens. The model determines which work order will be heated on which machine and in which time interval. The model results are launched for two different work order sets. Finally, by discussing the results, the applicability of the model is demonstrated. | |
