Food Supply System is one of the main elements of Army Logistics System. The ultimate objective in food supply system is to provide the food at the right time and at the right place. If this objective is achieved, the morale, the health and the strength of the soldiers on the battlefield will enormously enhance. In the literature, particularly in Turkish Army, there is no study which tests whether the existing food supply system operates properly or not under the war conditions and which shows the potential problem areas and which specify time standards under different scenarios. The objective of this study is to answer these questions by the help of simulation model of the system. This model can also be helpful to the staff officers who prepare logistic support plans. The simulation model of Army Corps Food Supply System is built in Arena 3.0. The results are analyzed by statistical methods. The related bibliography is also provided in the thesis.
