Evaluation of effectiveness of renewable energy sources
Vrobel, Marcel ; Sekničková, Jana (advisor) ; Bíza Bisová, Sára (referee)
The problem of comparing different sectors, companies, or projects occurs very often. This problem arises of poorly chosen metodics or requirements for results. The results of such comparisons are inconclusive and then useless. The contribution of this work is a practical guide which focuses on using of data envelopment models for evaluation of different options. In this thesis DEA models are presented on renewable energy sources. For proper understanding of the problems it is necessary to define what the data envelopment models (also known as DEA models) are. The purpose of this thesis is to inform about their creation and origins and also the description of their function. There is also an introduction into the teory of renewable energy sources. Renewable energy sources are evaluated based on their input. In this thesis is a comparison of biomass with solar, water and wind energy.

Multi-criteria portfolio analysis in conjunction with parametric programming
Hofmanová, Andrea ; Sekničková, Jana (advisor) ; Kuncová, Martina (referee)
The presented diploma thesis deals with the issue of multi-criteria decision making in practice. The main aim is to demonstrate the possibilities of involvement the parametric programming in multi-criteria linear programming (MCLP). The first, theoretically oriented chapter, describes the necessary theoretical knowledge. In this chapter is presented the role of financial planning together with essential relationships, by which is determined the rest of the work. This chapter also discusses the issue of multi-criteria linear programming including a description of selected a priori methods. The selected a priori methods are lexicographic method, utility function method, minimization of the distance from the ideal solution and minimal component method. The second chapter is devoted to the practical application of multi-criteria optimization portfolio with a parametric budget. For all the analyzed methods are firstly discussed models without integer conditions, and consequently their modification with these conditions. For the purpose of this work was used solver in MS Excel spreadsheet along with the created macro.

Application of methods of inventory optimization in supply chains
Červenka, Daniel ; Kuncová, Martina (advisor) ; Sekničková, Jana (referee)
As in the stock of trading business is allocated a large part of the capital resources, it is necessary to determine the manner of their control. For this purpose a number of models were developed. Before application to the specific case, these models must be properly adjusted to ensure conformity with reality. The aim of this thesis is to optimize the inventory management of electronic commerce. The stochastic model with loss from unfulfilled orders was chosen as default. First, the necessary adjustments were made to the model and defined input parameters. After filling model with real data, the optimum values of the monitored variables were obtained. The last part deals with the influence of changes in input parameters on the optimal value of variables. Use of the model is not limited to this particular case. Without major modifications, the model is also applicable to other similar problems.
