Scheduling for continuous production processes with order priority considered

Order oriented production has been paid more and more attention in modern industry. The significance of different customers is different to an enterprise, to the priority of order increases with the significance of enterprise, and to the order with high priority that must be satisfied first. In order to ensure the due-date of order with priority, a vector is used to describe the priority of orders, continuous time is discretized and the productivity of equipment is divided also, and then an for continuous industrial process with order priority and due-date time-window is proposed. A genetic algorithm has been adopted in this schedule problem in which the productivity of equipment at each interval is coded with real number, the simulations demonstrate the efficiency of the proposed model.
