PROPOSING A MODEL FOR THE SELECTION OF REPAIR & MAINTENANCE STRATEGY FOR IT SYSTEMS WITH THE HELP OF DEMATEL & ANP FUZZY PROCESS

Abstract

Repair & maintenance are the integral parts of using any technology which can affect the competitive priorities of organizations. Some changes have been made in dominant paradigms of production and in some other factors such as the progress of societies towards
an information society and various strategies of repair and maintenance. In order to select a repair & maintenance strategy for IT systems in this research, an attempt was made to present a comprehensive and scientific perspective as well as introducing an applied model on the selection of repair & maintenance strategy for IT systems in Tehran Cement Factory. In order to identify the effective parameters on research problems of the present descriptive functional study, a questionnaire with 51 indicators was developed and a population of 86 people answered it. Among these indicators, 21 of them were identified as effective factors on the selection of repair & maintenance strategy for IT systems in Tehran Cement Co. In the next step, the weight of each indicator and the dimensions of other questionnaires were determined on the basis of DEMATEL method and the technique of fuzzy analytic network process (FANP) and had been sent along with a letter for every member. After measuring the weight of each using DEMATEL method and fuzzy analytic network process, it was found that the time for equipments installation and commissioning, the amount of investments in information technology systems and the cost of buying equipments are of the maximum value and importance respectively.
