基于LCC理念下的变压器成本与质量评价联动分析应用
Linkage Analysis and Application of Transformer Cost and Quality Evaluation Based on LCC Concept

本文通过归集变压器在采购、运行维护及报废阶段的全寿命周期成本，评估各项成本与质量的关联性，筛选质量敏感成本用以构建质量联动评价模型，并结合质量敏感性分析，有效识别影响全寿命周期成本的关键质量因素，综合考虑投入、运维和报废期成本，旨在优化变压器的采购决策，体现模型在变压器采购与运维管理中的实际价值，促使其在电力行业的设备管理中发挥更加重要的作用，进而优化企业管理成本的同时，实现成本与质量的最优平衡，为设备的全生命周期管理提供科学依据。
The paper collects the whole life cycle cost of transformers in the stages of procurement, operation and maintenance, and scrap, evaluates the correlation between various costs and quality, screens quality-sensitive costs to build a quality linkage evaluation model, and combines with quality sensitivity analysis, effectively identifies the key quality factors affecting the whole life cycle cost, and comprehensively considers investment, operation and maintenance, and end-of-life costs. The purpose is to optimize the transformer purchasing decision, reflect the actual value of the model in the transformer purchasing and operation and maintenance management, and promote it to play a more important role in the equipment management of the power industry, so as to optimize the enterprise management cost, achieve the optimal balance between cost and quality, and provide a scientific basis for the whole life cycle management of the equipment.
