Abstract

The invention discloses a product quality control method during batch processing production process based on two-layer hybrid intelligent optimization. The method can ensure the maximal gain obtained during the batch processing production process by optimally controlling the quality control amount of batched products, relating to a batch processing production process in the industry, an intelligent algorithm and a traditional mathematic calculation algorithm method. The method comprises the following steps of: firstly taking the ending point of the batch processing production process as an optimal target according to the characteristics of the industrial production, and taking the limiting condition of the batch processing production process as a restraint condition of a target function; then optimally controlling the product quality during the batch processing production process based on the intelligent algorithm and the traditional mathematic calculation algorithm provided by the invention; and removing a model error through an iteration mode with an iteration method so as to gradually optimize an optimization performance index. The invention can ensure the highest product quality during the batch processing production process by combining the characteristics of the intelligent algorithm and the traditional mathematic calculation algorithm.
