In this paper we concentrate on optimization of combined-oriented CCR model in data envelopment analysis (DEA) with use a comprehensive interactive method with name PROJECT method. Interactive methods in multiple objective programming (MOP) are methods that can help to decision maker (DM) to generate the most preferred solution (MPS). The PROJECT method is able to obtain any efficient solution, contain nonsupported efficient solution and also identify the MPS, even in nonconvex cases. This interactive model is generated by combination the projection of the gradient of an implicit utility function on to the tangent plane of efficient frontier and the reference-point method to search for the best compromise solution within a local region. In this study, we will use the combined-oriented CCR model since this model analysis on both input and output, also the PROJECT method to showing the decision maker (DM) preferences in the process of assessing efficiency in the combined-oriented CCR model in DEA with any prior judgement.
