Efficiency Analysis of World's Top 20 Container Ports using Shannon's Entropy & DEA
초록
영어
Data Envelopment Analysis (DEA) is a non-parametric method widely used for efficiency assessment of units having similar characteristics. However, DEA method has several different models and the result of each model is usually different making the choice of the specific model difficult in assessing the efficiency of units. One way of overcoming this difficulty is to combine the different DEA models into an integrated one with each model being weighted according to some weighing method. In this regard, we use Shannon's Entorpy measure to combine the DEA models in such a way that all the efficiency results calculated from each model are considered in the integrated model to rank the units. For the study, the top 20 container ports in the world are compared for efficiency based on the traditional DEA method and the proposed method with Entropy.
