DEA Window Analysis for Measuring Port Performances Efficiency of Four Islands Countries Located in West Indian Ocean Countries

Abstract

DEA window analysis has been a great tool used in improving the economic impacts of ports through its efficiency analysis. This has been employed to ports found in West Africa, Europe, Asia ports; nonetheless, this has not been applied to Indian Ocean Island ports. The purpose of this paper is to investigate the port efficiencies of four island port countries found in the West Indian Ocean (port Reunion, the port of Colombo, Port Louis and the port of Toamasina). DEA window analysis is used to determine port efficiency and to observe the possibility of changes in port efficiency over time. Despite the measures were put in place to improve the efficiency of the port, corruption, unskilled labour and others are some inefficiencies that hinder the performance of the port. Implications and future research directions are also included in this study.

Two-Stage Super-Efficiency Slacks-Based Model to Assess China’s Ecological Wellbeing

“…(3) DEA Window Analysis. If the time is ignored or the performance of some DMU is compared to a period of time, this can result in an excessive use of resources and production deficiencies in future periods [ 45 ]. To overcome these issues, the DEA window analysis described in Charnes et al [ 46 ] can be used to determine the EWP and observe the efficiency shifts over time.…”

“…To overcome these issues, the DEA window analysis described in Charnes et al [ 46 ] can be used to determine the EWP and observe the efficiency shifts over time. The core concept of DEA window analysis suggests that the DMU in each period is a different DMU, which means that different reference sets are selected to evaluate the relative efficiency of the DMU using the moving average method [ 45 ]. The moving average method not only increases the number of DMUs, but also allows for the easy comparison of the DMU performance with the DMU performance in other time periods (i.e., longitudinal dimension) or with other DMUs in the same time period (i.e., horizontal dimension), which allows for a comprehensive analysis of the change tendencies in each DMU’s efficiency and a comparison of the differences between the DMUs.…”

“…To monitor the flexibility and accuracy of the measurement, a window length needs to be set. Although there is no current theory for defining window length, previous studies have suggested a window of 3–5 years [ 45 ]; therefore, as the EWP for the 30 Chinese provinces was assessed over a 12-year period, a 3-year window was selected.…”

Defining terminals' efficiency in a seaport using data envelopment analysis

“…The assessment of port efficiency using DEA begins with the appropriate choice of input and output variables [3]. It has been known that DEA results depend heavily on the selection of these variables [10].…”

“…Maritime transport can be considered as the backbone of the world globalization and trade because over 75% of the volume of international trade in goods is carried by sea, thus supporting significantly the ongoing and complex processes of global supply chains [1,2,3]. The port industry is, in general, an indispensable factor of development in a globalized economy [3]. At the same time, seaports play an integral role of utmost importance and act as an incentive to the development of the marine economy and national economy in general [2,4,5,6].…”
