Abstract

This paper study dynamic DEA model and proposes weight modeling in window analysis for multi-time period performance evaluation. It uses the weights of inputs and outputs generated as a result of static temporal efficiency evaluation to restrict weight flexibility in dynamic DEA model and observe the efficiencies, thus obtained, over multi-time period. First the optimal range of weights are determined and then it is being applied in different windows to observe the stability and consistency of efficiency evaluations. We also define consistent efficiency index and give numerical illustration to observe the working of proposed model.
