Since these systems are high-cost sytems, the design phase should be carried out in a planned manner. Reducing the design cost of electronic card holder systems and enhancing their functional performance characteristics is highly regarded and studied extensively by aircraft manufacturers. Many experts work in the design phase and therefore subjective judgements and evaluations bring uncertainities. In this context, the use of fuzzy set theory together with Quality Function Deployment (QFD) in the design phase will increase the performance of the QFD which will provide more accurate solutions. In the study, efficiency of the design process is tried to increase by using two phase Fuzzy OFD (FQFD) in the design process of electronic card holder systems based on company requirements. It is aimed to decrease production tolerances in electronic card holder systems. In the first phase, relative absolute weight of company’s requirements and relative importance weights of engineering metrics are identified. In the second phase, it was decided which piece characteristics will be changed in the new design. As a result, the need for minimum compression force among technical requirements and the ability to dissipate heat among company’s requirements are identifed as the most important issues. According to these, it was decided to make changes on control box guard}, number={1}, publisher={METE GÜNDOĞAN}
