Abstract
AbstractSustainability is an essential ingredient for long‐term success of firms, and its assessment has a significant impact on decision making and sustainability management. In the current paper, a data envelopment analysis‐based approach is proposed to assess the sustainability of systems over several periods when undesirable outputs are present in the process. Indeed, sustainability is assessed in each period and, as a whole, simultaneously. Furthermore, social, economic, and environmental efficiency scores of multiperiod systems are evaluated in each period. The weak disposability assumption is used to handle undesirable outputs. Also, the current study concerns socio‐economic, socioenvironmental, and eco‐environmental factors in addition to economic, social, and environmental aspects. A real‐world application on Iranian gas companies is used to illustrate the applicability of the proposed approach.
