A New Method for Optimization of Inefficient Cost Units In The Presence of Undesirable ‎Outputs‎

Undesirable Output such as pollution and waste may occasionally occur in the production process, which should be reduced to improve efficiency. In the present study, cost efficiency model is presented in the presence of undesirable output by Inverse Linear Programming, and the desirable cost is calculated in order to achieve cost efficiency for units that are technically efficient but not cost-‎efficient.‎
