Automatic preparation system of timing plan in steelmaking workshop

Abstract

The invention discloses a timing sequence plan automatic making system for a steelmaking workshop. The timing sequence plan automatic making system comprises a process parameter setting module, a system parameter setting module, a timing sequence plan requirement setting module, a requirement data preprocessing module, a timing sequence plan automatic making module and a timing sequence plan display module. The process parameter setting module is mainly used for providing various parameter setting functions. The system parameter setting module is mainly used for model parameters and algorithm parameters. The timing sequence plan request setting module downloads batched plans from the ERP, and stores the batched plans in a local database and provides the batched plan editing function at the same time. The timing sequence plan request preprocessing module serves as a bridge between the timing sequence plan requirement setting module and the timing sequence plan automatic making module, and is mainly used for extracting batched casting time plans, connecting information and steel type continuous casting permission information from the timing sequence plan requirement setting module. The timing sequence plan display module displays a timing sequence plan result Gantt chart obtained through calculation of the timing sequence plan automatic making module.

Description

technical field [0001] The invention belongs to the field of iron and steel production technology and information technology, relates to operations research modeling and intelligent optimization algorithms, and in particular relates to a method and system for automatically preparing a time sequence plan for a steelmaking workshop. Background technique [0002] With the rapid development of China's economy, the integrated production process of steelmaking-continuous casting has been greatly developed in my country's iron and steel enterprises. As a "soft power", the optimal control of steelmaking-continuous casting production has become an urgent need for iron and steel enterprises to save energy and increase efficiency under the severe situation of severe overcapacity in the current iron and steel industry. [0003] The literature "A production scheduling system at the stahllinz GMBH.Seoul: ProcInt 1Conf on CPC-93 in Steel Plant, 1993: 342~350" discusses that there are two t...
