Abstract
Subject of this thesis is the performance assessment of production units through prominent approaches in Network Data Envelopment Analysis. Network DEA is an extension of conventional DEA where each production unit has a complex internal structure. This thesis will focus on two-stage series processes. Common approaches in such context are those proposed by Kao et al. (2008) and Chen et al. (2009) with the multiplicative and additive model respectively as well as the weak link approach proposed by Despotis et al. (2016). The development of the aforementioned models will be performed through VBA scripts for Excel Application with the intention of automating the process of performance assessment of production units in Network DEA.
