یکپارچه سازی برنامه‌ریزی و زمانبندی تولید در صنایع فرآیندی چند محصولی با سیستم تولیدی پیوسته

  One of the main elements of each supply chain is production. Production planning in multi-products process industries in which products are subjected to the complicated operational constraints is a very hard work because production of computed optimal volume should be compatible with operation scheduling constraints of production system. Thus, integration idea has been proposed for required decisions of these two problems. The main dilemma in integration is how to make relation between production planning problem with middle term time interval and production scheduling problem with short term time interval. In this paper, we formulate and integrate production planning and operation scheduling problems in continuous process industries with multi products and capability of saving partial products in short and long terms time intervals. In continue, a heuristics solution approach has been proposed and its performance has been evaluated using a practical case study.
