The definition , the essential , the orietation model and eleven kinds of functions of mes was dissertated in the article , the relation between mes and the plan layer and the control layer was deeply analysised , and the characteristic of mes in the industry application was researched in detail . after analysised the current production condition and the existent problem in jigang plate plant , the design of system frame , dadabase and function module have been studied , and the realization of it has been expounded . for solving the low efficiency in arranging the rolling plan by man , based on the traveling salesman problem and the pack problem about 0 , 1 , the mathematics model of the schedule of rolling plan was put forward , and the most near insert way was introduced to solve it , the result was satisfied . based on the practical demands of jigang plate plant combined the academic research of mes software , it has been realized the valid combination between the management of production scene and the upper management software in the dissertation 本文论述了mes的定义及其实质、 mes的定位模型和其十一项功能,深入分析它与计划层和控制层的关系,并阐述了mes在行业应用中的特点。在分析济钢中厚板厂生产现状及其存在的问题后,研究了系统的体系结构设计、数据库设计和功能模块设计,并对其实现进行了阐述。为了解决人工经验编排轧制作业计划问题的低效性,提出了基于旅行商问题和0 1背包问题的轧制作业计划排序数学模型,并采用最近插入法进行求解,取得了满意的效果。
The necessity for the establishment of a device management information system is put forward through the analysis of the problems existing in the device management system at the medium plate plant of jigany . net work analysis as well as store and other mathematic methods are applied in this article . the other theories and methods from other fields are also used to these subjects include manufacture and operation management , technical economic , management financial , management strategy etc , the plan is composed of six aspects that inspection repairing , accident , malfunction , appendage , fixed assets 通过分析济钢中板厂设备管理系统存在的问题,提出了建立设备管理信息系统的必要性。采用了运筹学中的网络分析、存贮论等数学方法,借鉴了生产与运做管理、技术经济学、电子商务教程、财务管理及战略管理等基础课程中的方法,对信息系统进行了系统分析及系统设计,从点检、检修、事故故障、备件、固定资产和档案资料6个方面进行了详细的研究规划。
Based on above , a solution for compensation is made static var c ompensator , tailored to suit harmonic mitigation and reactive power compensation . drawing a comparison among all sorts of svcs , researching a suitable style for medium plate plant to mitigate harmonics and compensate reactive power , we can work out the theory foundation for the management of the grid system 为了更好研究交-交变频系统的谐波和无功冲击,我们就重钢中板厂35kv供电系统进行谐波测试和无功冲击造成的电压波动进行测试,从测试结果中分析和研究了交-交变频系统对供电系统的影响以及与理论计算的比较。
