Determining the effectual factors in enhancing efficiency in non-homogenous Decision-Making Units By utilizing the NDEA Approach (Case study: Cement Production Process)

Computing efficiency, without being attentive to its enhancement, is not a very desirable aspect and usually organizations, on the basis of targeting improvement assess efficiency. In the research presently conducted, on the fundaments of the efficiency gaged, in the numerous decision-making units (DMUs) of cement producers, the effectual factors implicated towards the enhancement of efficiency, have been brought into consideration. The efficiency of the DMUs have been calculated by taking advantage of the NDEA technique and the efficiency status of each one of the cement factories and its processes have been determined and compared to that, of the other factories. By utilizing this information, the root causes are primarily specified on the basis of the experiences of the experts, well versed in this subject-matter and consequently, by employing the Hierarchical Analysis Approach and the Wasserman’s Communication Technique, the factors influencing the efficiency of the cement production process, are focused on or prioritized. This method, from the viewpoint of a data collection method is descriptive, as well as, is accounted for being a Delphi survey procedure The results indicate that, four factories have an unwarranted consumption of alkaline materials whereas, eight factories are inclined towards calcareous materials. The treatment of chlorine, material-mixing time, the crushing of material, hardness and uneven texture, including, the sodium and potassium feeding rates are respectively, amidst the most crucial aspects, entangled, in an unsuitable consumption of alkaline and calcareous materials, on the grounds of which, solutions based on providing enhancement can be determined
