A proxy approach to dealing with the infeasibility problem in super-efficiency data envelopment analysis
Cheng, Gang; Zervopoulos, Panagiotis - Volkswirtschaftliche Fakultät, … - 2012
decision making units (DMUs). A major deficiency in the SE-DEA models is their infeasibility in determining super … infeasibility problem. The proxy introduced to the SE-DEA models replaces the original infeasible DMU in the sample and guarantees a …

Developing a hybrid comparative optimization model for short-term forecasting: an ‘idle time interval’ roadmap for operational units’ strategic planning
Filippou, Miltiades; Zervopoulos, Panagiotis - Volkswirtschaftliche Fakultät, … - 2011
Data drain and data uncertainties for rival units affect the reliability and effectiveness of strategic plans for individual operational units. This study introduces a stochastic, multi-stage, optimization technique for short-term forecasting that intends to assist policy makers in developing...

Panel Data Parametric Frontier Technique for Measuring Total-factor Energy Efficiency: Application to Japanese Regions
Honma, Satoshi; Hu, Jin-Li - Volkswirtschaftliche Fakultät, … - 2014
Using the stochastic frontier analysis (SFA) model, we estimate total-factor energy efficiency (TFEE) scores for 47 regions across Japan during 1996–2008. We extend the cross-sectional SFA model proposed by Zhou et al. (Applied Energy, 2012) to panel data models and add environmental...

A rational road to effectiveness attainment
Zervopoulos, Panagiotis; Vargas, Francisco; Cheng, Gang - Volkswirtschaftliche Fakultät, … - 2011
Operational effectiveness goes beyond efficiency while it incorporates exogenous variables, non-controllable by the service units. Effectiveness is a fundamental driver for the success of an operational unit within a competitive environment. In this context, we seek to identify the active units...

Airport efficiency: a DEA two stage analysis of the Italian commercial airports
Gitto, Simone; Mancuso, Paolo - Volkswirtschaftliche Fakultät, … - 2010
In this paper we use a two stage procedure, based on bias corrected DEA, to evaluate the impacts of regulatory reforms on technical efficiency of 28 Italian airports during the period 2000–2006. We employ two different DEA models: physical and monetary. The first relies on the aeronautical...
