• We present a new model for measuring multiperiod aggregative efficiency.
• The model ranks the full efficient decision making units.
• This model reduces computational complexity.
• The model provides the decision maker with aggregative efficiency of DMUs.

This paper proposes a super-efficiency model for measuring aggregative efficiency of multi-period production systems. The proposed model does not require any information on price data or preferential weighings of inputs and outputs over multiple periods and able to measure aggregative efficiency of multi-period production systems. The model computes efficiency score of each decision making unit (DMU) in each period. At the same time, the model classifies DMUs and ranks the fully efficient ones. Besides, the model provides a new technique for reducing the computational complexity of a recently introduced model. The proposed method is illustrated with a numerical example and proves to be effective and practical.
