Energy-saving production scheduling operation method and system for continuous batch lot-based heat treatment processes

摘要

An energy-saving production scheduling operation method and system are provided for optimizing the production scheduling of a continuous input lot-based heat treatment process in terms of cost, time, energy saving and delivery. Obtaining information on an order quantity of products and a capacity of each heating furnace according to an embodiment of the present invention; Scheduling a heat treatment process by applying information on the obtained product order quantity and the capacity of each heating furnace to a genetic algorithm; And putting the lot into each heating furnace according to the final result of the scheduled heat treatment process. Accordingly, the proposed algorithm and method may enable production scheduling capable of reducing cost and energy by deriving the scheduling of the heat treatment process by applying an industrial power time-based rate system (TOU). In addition, in consideration of the characteristics of the heat treatment continuous furnace process, reduction of working time and energy consumption through continuous input of the same lot is considered.If the preceding lot and the following lot are different, the additional waiting time and energy consumption time accordingly will be applied to the scheduling. Can be reflected. In addition, it is possible to apply to production scheduling by reflecting the product quantity and delivery date of urgent orders that occur during the schedule, and to satisfy the production volume for each product within delivery.
