Network DEA Approach to Organizing and Job Evaluation Process Assessment: Real Case of Iranian Oil and Gas Industry

All organizations have structure. Researchers emphasized the importance of the organizational structure to achieve the goals and mission of an organization. Thus Performance assessment of organizing is essential for managers and decision makers to find weaknesses and eliminate them. Organizations are designed by different methods and process, based on same principles and theories. In this study, process of organization designing in five organizations in field of oil and gas in Iran is examined. Main criteria and parameters that affect the efficiency of this process are identified and applied in an operational research framework. This research utilizes two stages Network Data Envelopment Analysis to construct a model to analyses the efficiency and effectiveness of mentioned process. the strength of this approach relation to traditional DEA and the need for extraction of efficiency of sub-processes (design of organization and job classification and evaluation) has caused to we develop a network related to considered process and utilize an additive efficiency decomposition approach to evaluate the relationships between efficiency of stages and overall  efficiency. Finally, based on the results, we recommend ways of enhancing the overall performance of this process.
