Closest targets in the slacks-based measure of efficiency for production units with multi-period data

The efficiency calculated from the conventional slacks-based measure (SBM) model is the minimum in terms of efficiency scores, and the corresponding target point requires more effort for an inefficient decision making unit (DMU) to become efficient. To find the closest target point to the assessed DMU, several models have been proposed via calculating the maximum efficiency. This paper proposes a set of models to measure the maximum SBM...
