This paper discusses the problem of evaluating the efficiency of a set of interdependent Decision Making Sub-units (DMSUs) that make up a large Decision Making Unit (DMU). The DMSUs are interdependent in the sense that some output produced by each DMSU is used as input by other one. The current paper presents a modified version of the DEA model to estimate the relative efficiency of DMSUs. The proposed method preserves the linearity of the CCR (Charnes, Cooper and Rhodes) model.
