Efficiency measurement of defense industry with fuzzy data envelopment analysis

As it is known, there have been promising developments in the defense industry in recent years. However, there is currently no study in the literature that reveals the effectiveness of the defense industry. It is aimed to measure the effectiveness of the defense industry by years and to measure the effectiveness of 5 companies operating in the defense industry. Accordingly, the effectiveness of the defense industry will be determined on an annual and company basis. For this purpose, fuzzy data envelopment analysis will be used. The aim of the thesis is to measure the effectiveness of the defense industry depending on the years and on the basis of companies. For this purpose, the efficiency of the defense industry will be revealed on an annual and company basis by using fuzzy data envelopment analysis. In the light of the findings to be obtained from this thesis, the effectiveness of the defense industry will be measured and revealed depending on the years and companies, and the effectiveness of the defense industry will be listed on an annual basis and on the basis of companies. There is no such study in the literature. In this context, a contribution will be made to the literature. In addition, the effectiveness of the defense industry will be scientifically demonstrated by fuzzy data envelopment analysis.
