Research And Development On Real-time Production Logistics Management System In Slab-yard

Under the incorporate product model of steel-making, casting, hot-rolling in steel enterprise, slab-yard is used to amortise the product line between the casting and hot-rolling, and the continuity and cost of slab operating is directly effected by the automatic level of its management。In previous Research, people concentrated in continuous casting and hot rolling of the planning and scheduling, ignored the storage management system Research and control.Based the demand of information constructing of Chongqing Iron and Stee Company Limited(CISC),the paper researched the designing and actualizing of the steel company 1780mm hot strip rolling manufacturing management system.It especially researched the slab-yard management.Based on the Justep Business platform and Oracle database,delphi as the development of language,the storage management system in MES was developed.The contribution aspects can be embodied:①The rules of slab location and pile position selection are analyzed. According to the factors we induce that affect the efficiency, based on the collaborative optimization of CC-HR operating plan, a slab location decision model which is subject to the limited HCR slab-yard storage and the rules of slab location and pile position selection is suggested. The model is a general optimal operation to a slab lot of entering slab-yard and can quickly optimize the pile position for each slab and the casting sequence. The advantages and disadvantages of genetic algorithms and simulated annealing algorithm are analyzed, and a genetic simulated annealing algorithmx is applied to solve the model. In the algorithm, it makes full use of the excellent whole searching ability of genetic algorithm, and the advantage that simulated annealing algorithm can efficiently avoid getting into part minimum, thus the global searching ability of is improved. The slab location optimization program based on GSA is realized and calculated many times.②Analysed the demand for the storage management system and the production logistics management information system of the Third Steel-Making Mill and the Second Hot Strip Mill rolling of CISC the storage management system has been designed and realized.③Based on the Justep Business platform and Oracle database,the storage management system in MES was developed.The material storage,technical quality, manufacturing plan,equipment,data gathering in the company were took charge by the manufacturing management system.It made the material flow and the information flow harmonious.The method of software engineering was adopted in system development, and requirement analysis, system design, detail design, programming and testing were applied to the system. finally, the storage management system was developed in the slab continuous casting direct hot charge rolling (CC-DHCR) integrated management system for CISC. The software run online now, and it work stability and reliability, have friendly graphic user interface, and reach the target of the project. Steel-Making Experts are very satisfied with this system in CISC.
