Enhancing DEA model : focus on time-controlled processes / Rasidah Mahdi

Data envelopment analysis (DEA) models have been applied to assess the relative efficiency of decision-making units, (DMUs). Here, the research problems focused on extending the application of DEA to incorporate time as one of the variables into the model formulation. The other focuses of this resea...
