In Data Envelopment Analysis (DEA), in addition to the efficiency score, the projection of inefficient Decision Making Units (DMUs) is also determined. In this paper, a model is proposed by using Centralized Resource Allocation (CRA) and Multi Objective Linear Programming (MOLP). In order to solve the proposed Multi objective model, we use the entropy and Z-W methods and obtain the projection of inefficient DMUs. The advantage of the proposed model, in addition to employing interactive methods, is that by solving one model instead of n models; the projection is obtained for all DMUs, which is closer to reality and more practical. Finally, a numerical example and an application are provided and the interactive and entropy methods are utilized.
