Advanced Optimization of Network Flows
Cabalka, Matouš ; Hrabec, Dušan (referee) ; Popela, Pavel (advisor)
The master’s thesis focuses on the optimization models in logistics with emphasis on the network interdiction problem. The brief introduction is followed by two overview chapters - graph theory and mathematical programming. Important definitions strongly related to network interdiction problems are introduced in the chapter named Basic concepts of graph theory. Necessary theorems used for solving problems are following the definitions. Next chapter named Introduction to mathematical programming firstly contains concepts from linear programming. Definitions and theorems are chosen with respect to the following maximum flow problem and the derived dual problem. Concepts of stochastic optimization follow. In the fifth chapter, we discuss deterministic models of the network interdiction. Stochastic models of the network interdiction follow in the next chapter. All models are implemented in programmes written in the programming language GAMS, the codes are attached.

Optimal pricing in nonlife insurace
Ďurošková, Zuzana ; Branda, Martin (advisor) ; Mazurová, Lucie (referee)
V této práci se zabýváme základními principy tvorby sazeb neži- votního pojištění. Pracujeme s rizikově heterogenním portfóliem obsahující ur- čitý počet rizikových tříd. Cílem je najíst optimální sazbu pojistného pro kaž- dou třídu. K nalezení aplikujeme optimalizační modely a využíváme nelineárního programování. Formulujeme a řešíme optimalizační problém za jistých podmínek. Odvodíme jeho optimální řešení, z kterého vyjádříme a popíšeme r·zné principy pro výpočet pojistného pro každou třídu. Zavedeme taktéž duální optimalizační problém a ukážeme tvar jeho optimálního řešení. V numerické studii vypočítáme z odvozených metod sazby pojistného, kde pro jednotlivá rizika reprezentující úhrny škod, budeme volit konkrétní rozdělení. 1
