<p>Gubici vode nanose veliku štetu vodovodnom sistemu, i ugrožavaju njegovo ispravno funkcionisanje. Cilj istraživanja je unapređenje sistema upravljanja gubicima vode, odnosno istraživanje mogućnosti smanjenja gubitaka u njima. Istraživanje se vrši na bazi međunarodno definisanih standarda i preporuka za smanjenje nefakturisane vode, a primenjuje se na javne sisteme vodosnabdevanja u Srbiji.</p> / <p>Water losses cause big harm to water supply system, and threaten its correct functioning. The aim of the investigation is improvement of water loss management systems in water supply processes, or the investigation of possibilities for reduction of water losses in them. Investigation is made based on international standards and guidelines for non revenue water reduction, and is implemented on public water supply systems in Serbia.</p>

The dissertation contains two major research projects. In the first project, we first study a multi-period inventory planning problem. In each period, the firm under consideration can source from two possibly unreliable suppliers for a price-dependent demand. Our analysis suggests that the optimal procurement policy is neither a simple reorder-point policy nor a complex one without any structure, as previous studies suggest. Instead, we prove the existence of a reorder point for each supplier. No order is placed to that supplier for any inventory level above the reorder point and a positive order is issued to that supplier for almost every inventory level below the reorder point. We characterize conditions under which the optimal policy reveals monotone response to changes in the inventory level. Furthermore, two special cases of our model are examined in detail to demonstrate how our analysis generalizes a number of well-known results in the literature. In the second project, we study a long-run inventory planning problem in which the retailer can replenish inventory and change price adjustment. We establish that it is optimal to change the price from low to high in each replenishment cycle, the optimal order-up-to level may decrease when the ordering cost increases, and fewer customers are served when the unit cost of procurement increases. Additionally, we provide efficient algorithms to compute the optimal stocking and pricing policies. / text
