Expert system and control method applied to blast furnace-converter sector production scheduling process control of steel enterprises

Abstract

The invention discloses an expert system and a method which are applied to the blast furnace-converter sector production scheduling process control of steel enterprises. The expert system comprises a knowledge base, a control rule set, an inference engine and an information processing part, the operation experience of workers is integrated to carry out reasoning discrimination and make necessary decision to realize reasonable scheduling on the basis of a queuing theory method and a system and simulation theory. A computer is controlled by a programmable logic controller suitable for process control to reasonably design a batch-arrival closed type repairable queuing network system which is composed of stations in a blast furnace-converter sector and has multiple service counters in parallel-series connection. The control system has simpleness and strong adaptability, can directly influence productivity of related equipment and running cost of the system, can satisfy actual production requirement, can save capital and can be widely applied to blast furnace-converter sector production scheduling system control of large-scale integrated iron and steel works.

Description

technical field [0001] The invention belongs to the technical field of iron and steel production planning and dispatching, and specifically relates to computer technology, queuing theory method, system and simulation and other theories, can be used in the blast furnace-converter section production dispatching system of iron and steel enterprises, and is used in the production dispatching process control of iron and steel enterprises. an effective method. Background technique [0002] At present, the plans of most domestic iron and steel enterprises are in the stage of manual compilation, which is inefficient and unscientific. Most of them lack the support of simulation systems and cannot give an objective judgment before production, which brings a lot of production risk. At the same time, in the process of implementing the production plan, there is a lack of comprehensive monitoring and evaluation of the implementation of the plan, and there is a lack of an effective schedu...
