Application of multi-criterial decision-making methods in Business Intelligence
Doubrava, Jiří ; Sekničková, Jana (advisor) ; Kobzareva, Maria (referee)
Enterprise Resource Planning systems are large source of information usable for management decision--making. However, these data are often kept in incomprehensible form for common user. Especially for support of management decision--making was developed set of processes and technologies called Business Intelligence. With its tools are created comprehensible analysis. On practical example there is shown that Business Intelligence tools can be easily used for generating entry data for multi--criterial evaluation of variants. Methods of multi--criterial evaluation of variants are applied to solve the problem of a company that is forced to close some of its stores due to financial loss.

Application of ELECTRE methods in practical analyzes
Fabian, Martin ; Sekničková, Jana (advisor) ; Kobzareva, Maria (referee)
We can include a variety of methods among the discrete multi-criteria decision-making models. One of those is the ELECTRE family methods. This still evolving group contains a large number of different methods and their modifications. Based on the obtained results the methods are divided into separating, ranking and sorting methods. An important factor affecting the results of these methods besides the threshold values is also determining the weights of criteria. First part of this thesis details theoretical description of these selected methods. In practical analysis methods are applied to real data. Comparison of results at the end of the thesis is devoted mainly to examining of the sensitivity of these methods to change of the weights of criteria.

Application of heuristic methods in real vehicle routing problem
Slavíková, Monika ; Fábry, Jan (advisor) ; Kobzareva, Maria (referee)
This thesis is continuation of the bachelor thesis "Model of delivery routes and placement logistics centers with opportunities of their optimization". It is about distribution problems and specifically a vehicle routing problem. The aim of this thesis is finding a solution of the vehicle routing problem which will be used repeatedly in the firm. The main task is achieving the lowest costs (total kilometers) with maximum utilization of vehicle capacity; in such conditions that all requirements of logistics centers will be satisfied and maximal capacity of vehicle will be tolerated. For calculation was used a solver Gurobi 6.0.3 in system MPL for Windows 4.2, which won't, however, provide the optimal solution and problem solving takes too long time. Next for calculation was used heuristics insert method and is written by VBA (Visual Basic for Applications) in MS Excel. Finally, there is a comparison of these methods with the original solution of the vehicle routing plan and solution of the bachelor thesis. Then the computational experiment was done, which tested effect to result, if other distribution center (starting point) will be bulit. The computational experiment was consist from heuristic insert method, solver Gurobi and heuristic saving algorithm from bachelor thesis.

Use of savings algorithm in messenger problem
Gőtz, Ondřej ; Fábry, Jan (advisor) ; Kobzareva, Maria (referee)
The diploma thesis deals with the use of heuristic methods for solving messenger problems. The first part focuses on the proposed vehicle routing problems, especially on travelling salesman problems and the messenger problems. For individual problems are theoretically discussed mathematical models for variants with one or more vehicles and the expansion of the use of time windows and capacity constraints. The second part introduces heuristic algorithms for the method of nearest neighbour, savings method, insertion method and the exchange method on the travelling salesman problems. Then all of the mentioned algorithms are modified for use in three variants of messenger problem. First, the disposition of one vehicle, the second allows more messengers in the same starting point and the last option is more messengers at different starting points. The last part describes computational experiments and comparison of results provided by different methods. The diploma thesis includes application for solving messenger problems using savings methods programmed in Visual Basic for Application in MS Excel.
