Material flow simulation optimization method in steel making-continuous casting production based on target guiding

Abstract

The invention provides a material flow simulation optimization method in steel making-continuous casting production based on target guiding. In the method, in order to meet continuous casting of a continuous casting machine, by the guiding action of the target, material flow objects are guided for simulating, evolving and operating in a production process network; with the help of the organic integration of global and local targets, rules and information, the self-organization evolution of the simulation process under traction and constraint of other organizations is realized, thereby obtaining simulation optimization results meeting actual targets and constraint conditions; and simultaneously, models can express and reflect the random characters of the operating time of each production procedure link in the production process, and evaluate the simulation results. The method can be used for optimizing production process design in steel making-continuous casting production, assisting in optimizing production operation, realizing the analysis on the rationality of the production process, establishing production planning, and assisting production scheduling.

Description

technical field [0001] The present invention relates to a logistics simulation optimization method for iron and steel metallurgical production process, in particular to a target-guided steelmaking-continuous casting production logistics simulation optimization method to carry out steelmaking-continuous casting production process optimization design and production operation plan Formulate and assist production scheduling, which belongs to the field of information technology. Background technique [0002] Steelmaking - continuous casting is at the heart of modern steel production. The operating efficiency and production organization of the steelmaking-continuous casting production process play a key role in the production and operation control of the entire steel manufacturing process.

[0004] Currently published patents related to steelmaking-continuous casting production logistics, such as CN1591337A (a computer-based simulation system for continuous casting logistics) simulate the production of continuous casting machines, including logistics in the rotary table, ladle, tundish The operation process of equipment such as flow, crystallizer, etc., and consider the influence of caster node layout on the production process, but this system only analyzes the single continuous casting production link, and does not consider the entire steelmaking-continuous casting production process; CN1564170A( The configuration platform method for optimizing scheduling and dynamic scheduling in the process industry) establishes a virtual production simulation model of the process industry through configuration, and uses the planning scheduling and dynamic scheduling algorithm model library for dynamic linking, transforming order contracts into production contracts, and dynamically Scheduling provides simulation tools for modeling different logistics layouts, but lacks necessary analysis means for simulation results, and its application in the steelmaking-continuous casting mixed process industry is limited; CN1556487A (a hierarchical coordination plan scheduling of steel production Method) The system is composed of an upper computer and a lower computer. The upper computer is used to optimize the overall goal, and the optimization target is issued to the lower computer. The lower computer expresses the production process and optimizes their respective production plans; the method is realized through the connection between the upper computer and the lower computer. The connection between the overall target of production and the local target of the process is identified, and the local production plan is optimized, but the method has a single connection between the overall target and the local target, and lacks a mutual evolution mechanism; CN101093552A (a computer-assisted guidance refinement Steel and continuous casting steel supply rhythm scheduling model) For the planned on-line heats, calculate the planned pouring time of each tank, and then calculate the working time of each tank immediately preceding the process from the pouring time, this method provides an auxiliary scheduling tool for production , but its process processing time and transportation time are definite values, and the lack of adjustment of the operation time may easily lead to conflicts in the operation plan
