影响港口性能的各种因素使港口效率的确定复杂化。本文提出了一种新的效率度量方法。数据包络分析（Data envelopment analysis， DEA）在服务业中具有特殊的适用性。应用数学规划技术。DEA可以在一组分析单元中推导出相对效率等级。因此，它不需要制定衡量效率的“标准”，尽管这些标准可以纳入DEA分析。单元的效率与包含组中效率最高的单元的“效率信封”进行比较。DEA方法将通过一个假设的数值示例来演示，其中比较了20个端口的性能。DEA效率评级对港口管理人员和研究人员来说是有用的工具，可以更深入地了解港口的表现。弱点可以被发现，引导到潜在的改进之路。
The large variety of factors that influence port performance complicates the determination of port efficiency. This paper presents a new approach to the measurement of efficiency. Data envelopment analysis (DEA), as a it is called, has particular applicability in the service sector. Applying mathematical programming techniques. DEA enables relative efficiency ratings ti be derived within a set of analysed units. Thus it does not require the developmentof ‘standards’ against which efficiency is measured, although such standards can be incorporated in the DEA analysis. The efficiency of units is compared with an ‘efficiency envelope’ that contains the most efficient units in the group. The DEA approach will be demonstrated by a hypothetical numerical example where the performance of 20 ports are compared. The DEA efficiency ratings can be useful tool for port managers and for researchers, providing a deeper insight into port performance. Weaknesses can be detected, leadungs the way to potential improvements.
