Uie sistemlerinin üçlü performans ve çkkv yaklaşımları ile değerlendirilmesi

Sustainability is getting increasing attention due to growing worldwide concerns about environmental protection and adaptation to the environmental regulations in developing industries. Especially, aviation companies are searching new ways to develop efficient products and services that can provide continuous sustainability in the sector. One of the breakthrough projects in the airline industry is wireless in-flight entertainment (WIFE) system that provides reduction of size, weight and energy consumption. It also offers increasing passenger satisfaction, cost saving, additional revenue and functional efficiency for airlines. The aim of the research is to assess the wireless IFE system by comparing with wired IFE system in respect of economical, customer and environmental viewpoints during the management of the sustainable supply chain operations. In the thesis, triple bottom line (TBL) and multiple criteria decision making (MCDM) approaches are employed to compare two different systems. Cost benefit analysis, customer satisfaction and environmental assessments are implemented in the research to assess TBL approach. Later, analytical network process (ANP) method is implemented for evaluating importance weights of criteria and technique for order preference by similarity to ideal solution (TOPSIS) methodology is proposed for ranking alternatives. The main contribution of the thesis is that a systematic approach have been constructed to determine and to maintain more sustainable and advantageous IFE systems in aviation industry.
