The invention provides a heat batch plan optimization method and device and a storage medium. The method comprises the steps that a hot rolling production order set to be scheduled, an unauthorized steel billet inventory set, customer requirement related data, production process data and equipment data are obtained; constructing a constraint satisfaction model according to the customer requirement related data, the production process data and the equipment data; solving the constraint satisfaction model by taking the production order set and the billet stock set as input data of the constraint satisfaction model to obtain a corresponding relation set and a residual order set; taking the remaining order set as input data of a constraint satisfaction model, and solving the constraint satisfaction model by adopting an optimization algorithm based on blank type weight to obtain an initial heat set; and solving the constraint satisfaction model by adopting a backtracking method and a constraint propagation method by taking the corresponding relation set and the initial heat set as input data of the constraint satisfaction model to obtain a final heat set. According to the invention, the compiling efficiency of the furnace batch plan is improved.
Description
technical field [0001] The present invention relates to the technical field of industrial production process optimization, in particular to a batch planning optimization method, device and storage medium for furnaces. Background technique [0002] In the process of steelmaking-continuous casting, heat batch planning is a key technical issue in the production organization of hot-rolled products. When compiling the batch plan for the entire batch, it is necessary not only to comprehensively consider customer requirements, production process constraints, and equipment constraints, but also to further consider the logistics balance and smoothness of steelmaking-continuous casting, steel areas, and hot-rolling areas, so as to provide a comparative Large optimization space, and then better play the enterprise capacity. [0003] At present, it usually relies on manual experience, using computers and other equipment to compile and optimize the batch plan of furnaces, but when faced...
