Possibility of linking optimization models with logistics technologies
Vrbická, Jitka ; Kuncová, Martina (advisor) ; Fiala, Petr (referee)
This thesis focuses on linking optimization model of mixed linear programming with logistics technologies. To achieve the objective, the thesis is divided into two sections. The first section provides the necessary theory on linear programming and logistics. The second part focuses on the optimization model itself and its connection with the method JIT. This section also describes the application created in MS Excel spreadsheet, which then solves the issue. The application is linked with optimization softwares Lingo and MPL for Windows. The thesis conclusion demonstrates functionality of the application on an illustrative example and the optimization programs are compared based on the observed data. Based on the collected data, we can say that the optimization model is a suitable tool for the optimization of supply chains.

Computer service ‒ an aplication of traveling salesman problem
Ryglová, Michaela ; Skočdopolová, Veronika (advisor) ; Dvořák, Marek (referee)
The travelling salesman problem is one of the most popular kind of route trip transportation problem. This thesis deals with the solution of traveling salesman problem to minimize distance in kilometres and focus on customer requirements, I am using data from firm CTR s.r.o. In addition to the basic model are also used mathematical model with modification tasks, so it is a model with hard time windows and a model with soft time windows. A practical solution is used in an optimization modeling language in Lingo software. The optimum solution was found for the model the traveling salesman and its modifications. The longest route 40.2 kilometers provides modification with a soft time windows, but gives the most emphasis on customer requirements. The shortest route 24 km is found with using a model the traveling salesman problem, but not considered any customer requirements.

The usage of the nutritional problem in real life
Salačová, Naďa ; Kuncová, Martina (advisor) ; Machovec, Bohumír (referee)
This bachelor thesis is about the usage of nutritional problem in real life, specifically about creating nutritional plan for professional athletes - basketball players. The main focus is to minimize the costs of the menu for one or five days, in which they will comply with all the nutritional requirements while respecting the exact calories intake (the amount of fat, sugar and protein). We will create four different menus - two for men and two for women. Each one has different requirements for the intake of those nutrients. Another goal for this research is to implement those menus into daily life of those athletes. They can be adjusted depending on the actual needs of each athlete. The perfect solution for all four menu choices can be found with software called LINGO.

Skočdopolová, Veronika ; Jablonský, Josef (advisor) ; Brezina, Ivan (referee) ; Šubrt, Tomáš (referee)
Goal programming is an approach for solving decision problems. The aim of this doctoral thesis is to show the practical use of this approach for solving real problems. The first chapter brings a brief introduction to multicriteria decision making. The second chapter is devoted to goal programming, its history, theory, criticism and also to its practical applications. The third chapter deals with description of a model for optimisation of white mass production. This model utilises the goal programming principle to deal with measuring deviations of raw materials' composition. A part of this chapter is a presentation of OPTIPROT, an application that implements the mentioned model. In the fourth chapter there are described three mathematical models for timetabling at a department level; two multistage models and one complex model. All three models are formulated utilising goal programming. In this chapter there is also described an application that implements the complex model for timetabling.
