Modelling of logistics of inter-municipal waste transport
Kučera, Jiří ; Popela, Pavel (referee) ; Nevrlý, Vlastimír (advisor)
This diploma thesis focuses on the issue of inter-municipal waste transport. The main part of the thesis focuses on the development of a computing core designed to create a collection plan for selected municipalities forming a union. The computing core was created so that it could be integrated into a user-friendly web application. The creation of a computational tool is based on the theoretical foundations of graph theory, mathematical programming and heuristic algorithms. In this thesis, consecutive algorithms for clustering of address points, collection design for several types of waste with a heterogeneous vehicle fleet and for creating collection proposal for a several-week long collection plan were developed. The presented approach was tested on real data from an existing union of municipalities in the South Moravian Region.

Modelling of gastro waste using GIS
Kyselová, Blanka ; Matějíček, Luboš (advisor) ; Vaněk, Ondřej (referee)
Gastro wastes, as a sort of biodegradable waste, has been established in legislation just quite recently, and its sorting is just in the beginning. However as a sort of waste it has a great potential like a secondary material. This work deals with gastro waste modelling and optimization of their cartage routes with purpose to decrease negative implications with them connected. For the model composition, the operational research was used, namely the transportation task or the circular transportation problem, further optimization (that includes the linear optimization and the index method.) The program ArcGIS and its extension Network Analyst from ERSI were used for delineation of transportation routes. Microsoft Excel, Visual Basic and Python were used for computation of optimization tasks. Final graphic output was carried out in the ArcGIS ArcMap. The results of this work are optimized trucking cartage routes, calculated values of minimal distances, quantity of cartage cars, calculated overall costs and other calculations. The part of this tasks is also time conversion of the model. Also, the attention was paid for minimization of trucking routes. The increase of the capacity of specific gastro waste processors was used for the minimization. These processors were chosen in accordance with required...

Application of the multicriterial decision making for an investment portoflio
Mulakaeva, Alfiia ; Brožová, Helena (advisor) ; Adam, Adam (referee)
The aim of this thesis is the selection of suitable investments (shares) for a particular investor and the creation of an investment portfolio with the help of multiple-criteria decision analysis.
The first part of the work summarizes the theoretical background of security portfolio creation, acquaints the reader with the concept of stocks and methods of analyzing equity instruments. It also provides an overview of the functioning of the capital markets generally and specifically in the Czech Republic. The second part focuses on the approaches and procedures for solving decision-making problems. Methodological apparatus includes systems analysis, linear optimization and multi-criteria decision making methods. The third part of the thesis concentrates on the application of this methods for the formation of the investment portfolio in the presence of multiple criteria. Most important ratios of the stock market and the magic triangle return, risk and liquidity are reflected in equities choice. Stock selection is carried out by using models of multi-criteria evaluation of alternatives in two rounds and portfolio composition is determined by the classical model of linear programming. As a result, investor gets a recommendation for his portfolio, which contains a number of shares of selected companies on the Czech market. This procedure of creating the portfolio can be used by individual investors, financial advisors and brokers and complement their knowledge, experience and intuition.
