Development of a Decision Support System for Computer Replacement Decisions

Nowadays, computers are extensively used in institutions and homes. At the end of the economic life cycles, computers should be replaced with new ones. In the computer replacement process at organizations, detailed evaluations about the hardware components should be carried on. Hardware components must be sorted according to their processing capacities and they should be presented to the managers as a management information system’s report to make a replacement decision. In this study, a decision support system (DSS) has been developed to monitor of the hardware specifications of the computer systems. In the developed DSS, Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) method is used as a multi-criteria decision making model. Thanks to the developed DSS, it is facilitated for managers to ranking of the computer systems for individual users. The developed DSS is applied to rank the computers for 125 employees in a faculty of engineering located in Ankara, Turkey
