【摘要】：由于流程工业中许多大型生产装置的平稳运行对企业生产至关重要,利用数理统计、计算机技术等手段建立起的装置平稳率控制系统在企业生产管理中得到了广泛的应用。然而,目前大多数已经实施的平稳率控制系统,由于平稳率统计数据不健全、系统孤立以及数据分析与应用功能不足等问题,并不能很好地发挥作用和改善生产。因此,很有必要从这些方面进行改善,优化系统的应用效果。为了解决这一问题,本文在分析流程工业生产装置平稳率控制的核心目标和需求的基础上,设计了一种可以从多维度反映装置平稳生产状况的平稳率统计算法,并以此算法为基础,从数据集成和核心业务处理两方面实现了具有良好应用效果的装置平稳率控制系统。本文从算法设计和系统的方案设计与实现两方面进行系统的设计,主要工作如下：(1)结合系统核心目标,基于对平稳率控制业务流程的分析,设计了适应不同应用场景的多维度平稳率统计算法。(2)通过设计平稳率数据集成平台,实现对平稳率系统核心数据的分析与建模,实现对某流程工业生产执行系统(MES)软件平台的数据集成,并保证系统数据的开放性。(3)提出并设计基于反馈思想的核心业务处理机制,使得平稳率统计数据能够及时反馈给生产人员,并对之进行进一步分析和利用,从而切实改善生产装置的平稳率状况。本文基于以上设计方案,实现了生产装置平稳率控制系统的设计,并对平稳率控制系统的功能、性能进行测试。系统实际应用于某大型流程型生产企业中,应用结果表明,该系统有效地实现了对生产装置平稳率状况的全面反映,并能够将统计结果在用户中及时应用与分析,形成反馈机制,从而真正有效地改善生产装置的平稳率状况,取得了显著的实际应用价值。
[Abstract]:Since the smooth operation of many large production units in the process industry is of great importance to the production of enterprises, the use of mathematical statistics, The device stationary rate control system established by computer technology and other means has been widely used in enterprise production management. However, most of the stationary rate control systems that have been implemented at present, because the statistical data of stationary rate are not perfect, The problems of system isolation and insufficient function of data analysis and application can not play a good role and improve production. Therefore, it is necessary to improve the system from these aspects and optimize the application effect of the system. In order to solve this problem, Based on the analysis of the core objectives and requirements of the stationary rate control in the process industrial production plant, this paper designs a statistical algorithm of stationary rate which can reflect the steady production condition of the plant in many dimensions, and based on this algorithm, In this paper, a device stationary rate control system with good application effect is realized from the aspects of data integration and core business processing. This paper designs the system from two aspects: algorithm design and system scheme design and implementation. The main work is as follows: (1) based on the analysis of the business process of stationary rate control, a multi-dimensional statistical algorithm of stationary rate is designed based on the core goal of the system. To realize the analysis and modeling of the core data of the stationary rate system, to realize the data integration of the software platform of a process industrial production execution system (mes), and to ensure the openness of the system data. (3) to propose and design the core business processing mechanism based on the feedback idea. So that the statistical data of the stationary rate can be fed back to the production personnel in time, and further analyzed and used to improve the stationary rate of the production plant. The design of stationary rate control system of production unit is realized, and the function and performance of stationary rate control system are tested. The system realizes the overall reflection of the stable rate of the production plant effectively, and can timely apply and analyze the statistical results among the users to form a feedback mechanism, so that the stable rate of the production plant can be really and effectively improved. It has obtained remarkable practical application value.
