Performance assessment of transport services with the ERM-NDEA model: evidence from a domestic airline in Taiwan

Abstract

This paper estimates comprehensive operational performance measures for transport services. A network efficiency approach is used to analyze the production efficiency, service efficiency, and operational efficiency in a unified framework to reflect the transportation service characteristics of airline operations. We show how a modified version of the network data envelopment analysis model can be utilized for evaluating the performance of air route operations. This study considers 15 air routes operated by a domestic airline in Taiwan to highlight the value of the approach. The results of the analysis show the inputs and consumed outputs leading to production inefficiency and service inefficiency respectively as well as the magnitudes of excesses and shortfalls.     

论航空承运人的法律责任

航空运输的高效、快捷及航空运输行业的专业技术信息的特点,决定了其承运人比旅客或托运人应具有更深的专业知识,因此,在性质上表现为平等的航空运输合同在诸多方面就呈现出不平等性.另外,航空运输本身所属的高风险行业又决定了其在整个运营过程中的任何差错都可能导致极其严重的后果,此种后果不论是对于旅客或托运人,还是对于承运人而言,都是难以承受的.本文以航空运输合同作为研究的出发点,依据中国<民用航空法>及<华沙公约>等国际条约,对承运人的法律责任进行较为详细的分析、评述,旨在完善航空承运人的法律责任.     

Some insights into competition between low-cost airlines

The phenomenon of the wide world growth in low-cost airlines has resulted in a focus on their pricing strategies, on issues of cost recovery and on their impact on the traffic and market shares of legacy carriers or other low-cost carriers when they are in competition, either directly or at adjacent airports.This paper provides a brief overview of the characteristics of these low-cost carriers as well as their history and geography. It goes on to outline ways in which these carriers compete and manage demand, ranging from price competition to advertising; some of these methods directly reflect their special characteristics. Some empirical evidence is presented which indicates a correlation in fare setting behaviour between competitors and insights are offered on cost recovery.The impact of the start-up of low-cost carriers is also analysed, focusing on their impacts on other low-cost carriers. The case of Ryanair competing with easyJet on London-Venice is examined along with Southwest and Frontier on Denver-Las Vegas.
