Quality and quantity of instruments and machinery, production management, physical structure and are the most important technical factors.Another factor affecting the efficiency is the economic factor. Here, the macro-variables of economy and the macro-indicators, which demonstrate the general economic condition, have to be considered. At times of economic depression, unemployment is a critical problem and depression results in consecutive dismissal of personnel. In such condition, the workers fail to work efficiently due to the fear of dismissal and this results in the decline in the efficiency of the organization. The role of these factors in increasing efficiency is studied in this paper. Educational technical courses, provision of standard equipment, new methods of warehousing and designation of capital credits such as the purchase of equipment and machinery and repairing tools leads to the promotion of efficiency in the maintenance units.
