“…Li et al [21] extended the Liang et al [21] model by assuming that input to second stage comprised the output from the first stage and additional exogenous input. Yu et al [30] recognized a deficiency in the Wang and Chin [27] model and proposed a novel method for transforming a two-stage process into a onestage process consisting of two independent parallel subprocesses.…”

Data Envelopment Analysis (DEA) research works have been recently examining production systems with a two-stage network structure. These studies consider system operations that are performed in two stages where intermediate products play dual roles: they are the outputs of the previous stage and inputs to the next stage. This dual role is incompatible with Pareto-Koopmans dominance in activity analysis. Also, disregarding intermediate products in assessing performance of two-stage systems compromises the models. The present work introduces a new production possibility set for two-stage network production systems by considering a convex hull for intermediate products. In addition, new models are introduced for evaluating overall efficiency and divisional efficiency of production units from the Pareto-Koopmans efficiency perspective. The proposed models are developed based on an enhanced Russell graph model for efficiency evaluation of twostage network production structures with convex hulls for intermediate products. Numerical examples are further provided for illustration purposes.

“…Since Charnes et al [1] proposed the so-called data envelopment analysis (DEA) approach, which is derived from the idea of non-dominated solution [2], for performance evaluation, many variant models has been developed ( [3], [4], [5]). Some representative models that pertain to single-level situations are the Variable Return to Scale model [6], the Additive model [7], the Slacks-based measures [8], the Russell measure ( [9], [10]), and some Non-radial models ( [11], [12]).…”

Comparing performance by conventional DEA model, some DMUs may be considered as eff icient units because of their outstanding performance on some relative unimportant output items. For expressing the relative importance of those input or output items, adding multiplier restrictions on them is a possible method. In this research, we try to add the strictly predefi ned relationships of output items and analyze its eff ect in the existed model. According to this approach, only the DMUs that really match the predefi ned requirements and have good performance can be regarded as eff icient units. This is meaningful for managerial practices. That is to say a DMU's performance is its capability which matches the goals that the organization pursues. A case of performance evaluation of faculty in diff erent types of university with specifi c development orientation is provided to illustrate the proposed idea. According to the numerical experiment, the performances of the faculties may be dissimilar considering diff erent types of universities. The signifi cance of those eff icient faculties is also diff erent.
