  • Abstract

    The paper analyzes the operation of a defense logistics system. In more detail, the examined system consists of a one warehouse, the first supply echelon and four battlefields, the second supply echelon, which face four non-identical demand rates. Characterized as a divergent dynamic supply network, the system is analyzed by modeling it as markovian process with discrete space. Major outputs of the modeling process are the evaluation of the performance measures of Work In Process (WIP) , Fill Rate (FR) and the presentation of the behavior of the performance measures in relation with a number of variables such as safety stock (s) , replenishment rates () and demand rates (l).
