【摘要】：零部件加工企业将资源转变为产品的过程会消耗巨大能量,同时也会对环境造成很大影响如排放大量的二氧化碳。零部件加工作为制造业产品生产的主要过程,在制造业的节能和减排中扮演着重要角色。碳排放量评估作为零部件加工过程中对环境影响的重要指标,是制造业实现低碳加工的基础。关于如何在零部件加工过程中对碳排放量进行有效计算的问题,本文进行了深入研究,建立了基于工序碳源的零部件加工过程碳排放评估模型。并对工序碳排放误差进行分析,建立工序间误差关系。为在整个加工过程中碳足迹产生异常的根源和改进碳排放量提供依据。第一章,主要探讨与总结论文研究的背景、目的以及意义,并总结与分析零部件加工过程碳足迹的国内外研究现状。第二章,分析了零部件的生产加工过程,从零部件的信息出发设计加工方法,从而确定零部件加工过程的工序流。并对零部件特征信息与加工方法、加工方法与设备它们之间的关系进行探讨,确定映射关系。在此基础上对零部件加工过程碳排放特性进行阐述,并对影响工序碳排放量不确定的因素进行了分析。第三章,针对零部件加工过程碳排放量的分析与计算问题进行研究,提出了基于工序碳源的碳排放评估模型。首先在零部件加工过程的碳排放特性基础上构建工序碳源,进而分析工序特征,建立工序特征四大要素,同时确立工序碳源的计算规则,提出了物料消耗工序碳源、空载工序碳源、负载工序碳源、基础设施碳排放的计算评估模型,实现了零部件加工工序的碳排放计算方法。第四章,分析加工过程误差的来源、分类,先介绍了单工序碳排放量独立误差,运用层次分析法对关键误差源进行提取;接着阐述多工序加工过程工序碳排放量的误差函数,使用相关分析法,来讨论工序间的相关性,运用回归算法来验证工序间的拟合函数,进而建立多工序间碳排放量误差关系。第五章,结合零部件加工过程碳排放计算方法,以某电能表制造企业为对象,开发了零部件加工过程碳排放评估系统(C-CAPP)。从开发思路和结构来对系统的总体设计进行说明,并对系统的主要功能模块逐一进行介绍。第六章,对全文研究内容进行总结,并对今后的进一步研究工作进行展望。
[Abstract]:The process of converting resources into products by parts processing enterprises will consume a great deal of energy, and at the same time will have a great impact on the environment, such as the emission of a large amount of carbon dioxide. Parts processing is the main process of manufacturing products. It plays an important role in energy saving and emission reduction in manufacturing industry. It is the foundation of low carbon processing in manufacturing industry. This paper makes a deep research on how to calculate the carbon emission effectively in the process of parts processing. A carbon emission assessment model based on process carbon source is established, and the error of process carbon emission is analyzed. To establish the error relationship between the processes, to provide the basis for the origin of carbon footprint anomalies and the improvement of carbon emissions in the whole processing process. Chapter 1, mainly discusses and summarizes the background, purpose and significance of the research. And summarizes and analyzes the domestic and foreign research status of carbon footprint in the process of parts processing. Chapter two analyzes the production and processing process of parts and components, and designs and processes methods based on the information of parts and components. In order to determine the process flow in the process of parts processing, and to discuss the relationship between the characteristic information of parts and the processing methods, the processing methods and the equipment. On the basis of this, the carbon emission characteristics of parts and components processing process are expounded, and the factors influencing the uncertainty of process carbon emissions are analyzed. Based on the analysis and calculation of carbon emissions in parts processing process, a carbon emission assessment model based on process carbon source is proposed. Firstly, the carbon source is constructed on the basis of the carbon emission characteristics of parts processing process. Then the paper analyzes the process characteristics, establishes the four elements of the process characteristics, establishes the calculation rules of the process carbon source, and puts forward the calculation and evaluation model of the material consumption process carbon source, the no-load working procedure carbon source, the load working procedure carbon source, and the carbon emission from the infrastructure. In chapter 4th, the source and classification of the process error are analyzed, and the independent error of the single process is introduced, and the key error source is extracted by the analytic hierarchy process (AHP). Then the error function of carbon emission in multi-process process is expounded. Correlation analysis method is used to discuss the correlation between processes, and regression algorithm is used to verify the fitting function between processes. Chapter 5th, combined with the calculation method of carbon emission in the process of parts processing, takes an electric energy meter manufacturing enterprise as an object. A carbon emission assessment system for parts processing is developed. The overall design of the system is explained from the development idea and structure, and the main function modules of the system are introduced one by one. Chapter 6th summarizes the research contents of the whole paper. The future research work is prospected.
