The aim of this paper is to propose a mixed structure network data envelopment analysis (MSNDEA) model which allows a representation of a parallel production serial connection of consumption processes in a unified framework and hence can be used to simultaneously estimate the production...

The purpose of this paper is to apply a hyperbolic graph efficiency approach to measure "return to the dollar" at the station-level of the Taiwan Motor Transport Company before and after privatization. The "return to the dollar" measure is decomposed into two components: a technical efficiency...

<title>A<sc>bstract</sc> </title> This study employs the directional graph distance function and the multiactivity data envelopment analysis (DEA) approach, which incorporates both desirable and undesirable outputs, in order to provide a more complete representation of the multimode bus production technology from which...
