Smoothing the frontier in the DEA models

Krivonozhko, Vladimir W.; Førsund, Finn R.; Lychev, … - 2016

Some inadequate results may appear in the DEA models as in any other mathematical model. In the DEA scientific literature several methods were proposed to deal with these difficulties. In our previous paper, we introduced the notion of terminal units. It was also substantiated that only terminal...

Comment on Some Mathematical Properties of a DEA Model for the Joint Determination of Efficiencies

Ding, Jingjing; Zhang, Peng; Feng, Chenpeng - 2013

Molinero and Tsai (1997) proposed a data envelopment analysis (DEA) model to evaluate a production entity that is characterized by shared inputs and shared outputs. They claimed that their proposed model has a convex solution space, and thus a convex program. This conclusion, if it were correct,...
