Description

A SEC Index Evaluation Method Based on Combination Weighted Comprehensive Evaluation Model

技术领域 technical field

本发明涉及一种基于组合加权综合评价模型的SEC指标评估方法，属电网资产全寿命周期管理评估分析技术领域。The invention relates to an SEC index evaluation method based on a combined weighted comprehensive evaluation model, and belongs to the technical field of evaluation and analysis of the life cycle management of power grid assets.

背景技术 Background technique

综合评价指对多目标结构系统或多属性体系结构系统，根据一定方法做出全局性、整体性的评价，再根据评价值择优或排序。综合评价由于影响因素较多，涉及面广，因此具有一定的复杂性，是评价问题研究的重点。目前对综合评价问题的研究大致可以分为两类:一类是对评价指标体系的研究;另一类是对综合评价方法的研究。对于评价体系的研究，不同领域、不同评价主体、不同目标往往差异很大，所以此方向的研究具有建设性的意义。Comprehensive evaluation refers to making a global and holistic evaluation of multi-objective structural systems or multi-attribute architectural systems according to certain methods, and then selecting or ranking according to the evaluation values. Comprehensive evaluation has certain complexity because of many influencing factors and involves a wide range of areas, so it is the focus of evaluation research. At present, the research on the comprehensive evaluation problem can be roughly divided into two categories: one is the research on the evaluation index system; the other is the research on the comprehensive evaluation method. For the research on the evaluation system, different fields, different evaluation subjects, and different goals are often very different, so research in this direction is of constructive significance.

供电企业资产全寿命周期管理评价要求既能体现评价实施的普适性，又能够在具体工作上体现针对性，可以根据不同的评价目标和评价需求调整指标数目而不影响评价。建立科学合理的指标体系、评估流程和评估模型，可以科学评估、引导、促进资产全寿命周期管理的健康快速发展，可以提高企业投资的有效性、提升财务表现，减少安全风险、完善企业安全战略决策机制、优化安全资源配置、整合安全管理体系与政策，减少维修成本、优化成本构成，最终实现企业资产管理水平的质的提升。The evaluation requirements for the asset life cycle management of power supply enterprises can not only reflect the universality of evaluation implementation, but also reflect the pertinence in specific work. The number of indicators can be adjusted according to different evaluation objectives and evaluation needs without affecting the evaluation. Establishing a scientific and reasonable index system, evaluation process and evaluation model can scientifically evaluate, guide and promote the healthy and rapid development of asset life cycle management, improve the effectiveness of corporate investment, improve financial performance, reduce safety risks, and improve corporate safety strategies Decision-making mechanism, optimization of security resource allocation, integration of security management systems and policies, reduction of maintenance costs, optimization of cost components, and ultimately a qualitative improvement in the level of enterprise asset management.

根据评价主体的评价要求，目前应用非常广、效果明确、且相对适合的多属性评价方法主要有加权综合法、目标规划法、TOPSIS 法，该类方法对评价对象描述比较精确，可以处理多决策者、多指标、动态的对象，但缺点是无法涉及有模糊因素的对象；统计分析方法有主成分分析法、聚类分析方法等，该类方法具有全面性、可比性、客观合理性的优点，但缺点是因子负荷符号交替使得函数意义不明确、需要大量的统计数据、没有反映客观发展水平；系统工程方法有层次分析法等，该类方法优点是可靠度比较高、误差小，但缺点是评价对象的因素不能太多。由于该评价指标体系存在分层较多、指标数量较多、指标不易简化，指标间的关联程度相差较大、指标可量化、指标数据积累量较少的特点。According to the evaluation requirements of the evaluation subject, the currently widely used multi-attribute evaluation methods with clear effects and relatively suitable methods mainly include the weighted comprehensive method, the goal programming method, and the TOPSIS method. These methods describe the evaluation objects more accurately and can handle multiple decisions. object, multiple indicators, and dynamic objects, but the disadvantage is that it cannot involve objects with fuzzy factors; statistical analysis methods include principal component analysis, cluster analysis, etc., which have the advantages of comprehensiveness, comparability, and objective rationality , but the disadvantage is that the meaning of the function is unclear due to the alternation of factor load symbols, a large amount of statistical data is required, and it does not reflect the objective development level; systems engineering methods include analytic hierarchy process, etc. The advantages of this type of method are relatively high reliability and small error, but the disadvantages There cannot be too many factors to be evaluated. Because the evaluation index system has the characteristics of many layers, a large number of indicators, difficult to simplify the indicators, large differences in the degree of correlation between indicators, quantifiable indicators, and less accumulation of indicator data.

经过综合比较发现加权综合评价法对指标的数量和指标体系的复杂程度上没有要求，并且不需要进行指标体系的简化，可以根据不同的评价需求可以通过选取对应的指标来实现，对于指标体系内指标关联程度不一致的问题可以通过线性加权与非线性加权组合评价解决。因此结合管理评价主体的要求，评价指标体系的特点和数据的特点，选择组合加权评价方法实现对资产全寿命周期安全管理、效能管理、成本管理及综合管理的评价。After a comprehensive comparison, it is found that the weighted comprehensive evaluation method has no requirements for the number of indicators and the complexity of the indicator system, and does not need to simplify the indicator system. It can be realized by selecting corresponding indicators according to different evaluation requirements. For the index system The problem of inconsistent index correlation can be solved by combining linear weighting and nonlinear weighting evaluation. Therefore, combined with the requirements of the management evaluation subject, the characteristics of the evaluation index system and the characteristics of the data, the combined weighted evaluation method is selected to realize the evaluation of the safety management, efficiency management, cost management and comprehensive management of the asset life cycle.
