Purpose The purpose of this paper is to develop data envelopment analysis (DEA) models and algorithms for efficiency improvement when the inputs and output weights are restricted and there is fixed availability of inputs in the system. Design/methodology/approach Limitation on availability of...

A two-stage system composed of three sub-systems, where the independent two sub-systems of the first stage are linked in parallel and then linked to the third sub-system of the second stage in series, known as two-stage parallel-series system. The deterministic two-stage parallel-series system...
