The optimal output model packaging steel strip

Packaging steel strip optimal output model in most manufacturing companies, its often mixed flow production lines, products many varieties, the characteristics of the single small batch, product varieties changes frequently, often cause the workstation transformation process equipment. Current research of many varieties of production scheduling method is relatively mature, first of all, an optimal packaging steel strip production model, each product production and processing time is obtained by calculation, then the critical path method is applied to implement the packaging steel strip of scheduling problems, finally sorted result was calculated by the LINGO language. Calculation examples show that the method for large-scale manufacturing enterprise of production scheduling problem. Packaging steel strip production process is a multi-stage optimal output model, constraint is different in various processes, but planning method is the same, mainly in the key process for hot rolling and cold cut two process as the main constraint condition of project, steel strip production scheduling and production process there is light, starting from the actual production process, to establish a general model and algorithm, can make it suitable for the steel belt production batch scheduling.
