【摘要】：针对DEA方法在船型技术经济综合评判中存在的不足,通过在DEA原模型基础上引入理想决策单元,利用灰色关联度分析方法建立评价指标体系,将分级有效性评价的思想运用到评价过程的方式对原DEA方法进行改进。文中的分析及计算实例表明,改进DEA方法具有简明、实用的特点,是进行船型多方案优选决策的有效方法。
[Abstract]:In view of the shortcomings of DEA method in the comprehensive evaluation of ship type technology and economy, an evaluation index system is established by introducing an ideal decision making unit based on the original DEA model and using the method of grey correlation analysis. The idea of hierarchical effectiveness evaluation is applied to the evaluation process to improve the original DEA method. The analysis and calculation examples in this paper show that the improved DEA method is simple and practical and is an effective method for optimal selection of ship types.
