Abstract

The invention provides a data coordination method based on accelerated generalized reduced gradient, pertaining to the field of information technology. The method is used for coordinating bilinear metal balance data in a real industry and comprises the following steps: firstly, solving minimum cost according to a constraint equation or utilizing a penalty function method in conjunction with an improved particle swarm algorithm to solve such that early-period acceleration is performed and a initial feasible solution is acquired; on the former basis, applying an improved generalized reduced gradient algorithm in conjunction with optimal selection of basic variables, optimization of iteration step lengths and the like in order to perform accelerated solving operation, thereby acquiring a final data coordination result. While ensuring precision, a bilinear data coordination problem is effectively and rapidly solved, which better helps statisticians on spot balance and optimize work including material, resources and production processes.
