摘要
随着天然气行业的不断发展,天然气客户规模逐渐扩大,客户的用气指数和类型将更加复杂,需要进行天然气销售企业客户价值评价体系研究。数据包络分析法并不直接对数据进行综合,排除了许多主观因素,具有很强的客观性,且在多投入和产出问题中具有优势。以商品气投入量、销售投入量、成本、运费4项为投入指标,以调峰贡献、回收气费、销售价格3项为产出指标建立天然气客户价值评价体系,采用CCR-DEA模型、BCC-DEA模型进行评价计算,通过技术效率、规模效率、总效率来评价各个决策单元,并通过计算模型的松弛程度来判断DEA模型的有效性。选用部分客户进行初步评价,评价结果显示,设计的模型能够根据天然气市场的变化给企业管理者提供决策建议。
It is necessary to study the customer value evaluation system of natural gas sales enterprises when the scale of natural gas customers is gradually expanding and the gas consumption index and type of customers will be more complex with the continuous development of the natural gas industry.Data envelopment analysis,excluding many subjective factors and with strong objectivity,does not directly synthesize data and has advantages in multi-input and output problems.This paper establishes a natural gas customer value evaluation system with four input indexes of commodity gas input,sales input,cost,and freight,and three output indexes of peak shaving contribution,recovered gas fee,and sales price.CCR-DEA and BCC-DEA models are used for evaluation and calculation.Each decision making unit is evaluated by technical efficiency,scale efficiency,and total efficiency,and the effectiveness of DEA model is judged by calculating the relaxation degree of the model.Some customers are selected for preliminary evaluation and the evaluation results show that the designed model can provide decision-making suggestions to enterprise managers according to the changes in the natural gas market.
