【 摘 要 】

References(8)Cited-By(3)A scheduling method that incorporates the design of multipurpose batch plants is developed. The scheduling consists of two interactive sub-problems: production scheduling and constrained resources scheduling, and on-site work is one of the typical constrained resources. In the design of these plants, the optimal schedule should be made within a short time, and cyclic scheduling according to the cycle production is appropriate. An IP (Integer Programming) model is suitable for such short-term scheduling, and the scheduling method is developed on the basis of the previous IP model for production scheduling. To make the optimal schedule, the allocation and sequence of tasks of on-site work should be optimized in relation with the production scheduling. In this study, the required properties of the on-site work scheduling in design is considered, and this sub-problem is converted into an assignment problem. The on-site work is defined in linear constraints with integer variables describing the task assignments. Moreover, the on-site work is newly defined in the production scheduling, and these definitions are related by the introduced integer variables. Finally, the effectiveness of the developed scheduling method is demonstrated by an example problem.
