Abstract :

In this research, with the improvement of previous existed models and surveying of structural similarities, more efficient model will be offered which is able to an evaluation of DMU performance of a two-stage system simultaneously and also the consequent assessment of the system’s operation. Improved procedures and solutions are offered in such a way that following them the ideal efficient situation can be figured out. The proposed model can solve the previous models’ issues which can lead to impractical and invalid responses. The practical result of this research is the conceptual model for evaluating the performance of projects and inspection of electronic protection in Sorena System Company, where a method is created for optimizing the impact of each component of the primary inputs over the final output and consensus performance of projects effectively and efficiently.  The cost of advertising, personnel and equipment’s programs in Rials (as the three factors of input), the monetary value of provided services of (private and public) inspection and electronic protection projects (as two intermediate output component) and the quantity and index‘s monetary value of deviant work in inspection and electronic protection projects (as two components of the final output targets) will be analyzed.
