Verimli ve Ekonomik Klima Sistemlerinin Seçiminde Bulanık AHP Metodu

Significant increases in energy costs realized in the last forty years. In the 1960s per barrel of oil was 2 USD, today it is within 90 to 120 USD ranges. This great change made the concepts of energy conservation and efficient use of energy more important while technological developments have increased the comfort expectations of the people. Another major problem is pollution of the environment and living spaces. As a result, installation of air conditioning systems to be more economical and cooling and heating are sought to be done more economically on the one hand, breakdown of the systems to do less, be quieter, do not pollute the environment, have lower fuel consumption and maintenance, operations are required to be easier and cheaper on the one hand. For these reasons, air-conditioning systems’ investment decisions appears to be a complex process to consider various factors. Each factor that taken into consideration here will ultimately affect the decisions at the different degrees is increasing complexity of the decision process. In recent years for taking of decisions like this, analytical hierarchy process (AHP) is one of the methods suggested. In this study, a solution is searching with the fuzzy AHP method for the selection of an education institution’s investment decision problem of the air-conditioning systems. For this purpose, airconditioning systems on the market is evaluating with in the decision criteria that is determined by an expert to make a proposal.
