Monitoring efficiency and productivity of promoters in wind energy sector

A DEA framework is proposed to explore the differences in performance of a set of wind farms, which involves two main promoters in the Portuguese wind energy sector. The study investigates the efficiency of the promoters in maximizing the energy produced from the physical resources and the wind velocity available in each farm. The overall performance of the two promoters is analyzed by comparing their differenc...

Performance comparison of retailing stores using a Malmquist-type index

This study develops a framework that combines different management science methods to provide insights concerning the performance of retailing stores. First, the framework enables to specify appropriate targets for stores of a retail network using data envelopment analysis. This involves comparing stores within homogenous groups, that is, supermarkets and hypermarkets. Second, the framework compares the overall...
