Limited resources in Data Envelopment Analysis with imprecise and integer data

In this paper a new model which is in the framework of centralized models in data envelopment analysis (DEA) is proposed. The existing models which have been presented for the human resource rightsizing organized in two stage and the models were suggested especially for integer data. In this paper we improve the existing models in one stage only and consider both imprecise data and integer data in our suggested model. With the numerical results, the limited resources are reallocated among different $\alpha$-level sets along with the consideration of integer data in the proposed model.
