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.

This thesis presents an application that performs positioning of modules automatically based on given data for every module, and the development of it. The basis of the application is from a previous thesis code. On top of that code, more features and error handling has been added, as well as fixes for various bugs. A stress test has been performed and further development possibilities are being presented. The thesis work was carried out at Toyota Material Handling Mjölby (TMH) and was made in parallel with another thesis by Fredrik Holden who was generating data for the application. For a complete understanding of the theory and background, please also read Holden’s thesis report “Development of method for automated positioning of 3D-representations of a modularized product”, as well as the former thesis  ”Analysis for Automated Positioning of 3D-representation of a Modularized product””. / Detta examensarbete presenterar en applikation som positionerar moduler automatiskt med hjälp av given data för varje modul, samt utvecklingen av applikationen. Applikationen bygger på kod från ett tidigare examensarbete. Ovanpå den koden har flera egenskaper och felhanteringar lagts till, samt har olika buggar fixats. Ett stresstest har också utförts och framtida utvecklingsmöjligheter presenteras. Examensarbetet genomfördes på Toyota Material Handling Mjölby (TMH) och gjordes parallellt med ett annat examensarbete av Fredrik Holden som genererade data för applikationen. För en fullständig förståelse angående teorin bakom samt bakgrunden till examensarbetet, vänligen läs också Holdens rapport ”Developmentof method  for automated positioning of 3D-representations of a modularized product”, samt rapporten från föregeånde examensarbetet ”Analysis for Automated Positioning of 3D-representation of a Modularized product”.

The diploma thesis is focused on the creation of a program enabling calculation of selected economic indicators of Arbela s.r.o. The thesis is divided into a theoretical and practical part. The content of the theoretical part is a description of individual methods and procedures of financial analysis, description of principles of time series, and regression analysis. In the practical part, the program created to calculate the selected economic indicators of the company Arbela s.r.o. is presented. These indicators are subsequently evaluated and foreseeable development of the company is determined for the future. At the end of the thesis, solutions for possible improvement of the economic situation of the company can be found.

The master’s thesis deals with the use of fuzzy logic for evaluating the quality of suppliers of IT goods and other material for a selected company. The fuzzy model should facilitate decisions when selecting individual suppliers who should deliver goods for the implementation of IT projects. The model created in Microsoft Excel and MathWorks MATLAB should be helpful to the company's management and sales representatives.

The orienteering problem is one of the newer problems in the field of discrete programming. The formulation of this problem originates from a sport discipline, called orienteering. In the beginning of this thesis a formulation and mathematical model for this problem are introduced. The extension of the problem is the team orienteering problem, described in the next chapters of theoretical part. Many heuristics were published for this problem. While the heuristic of Chao et al. and a path relinking approach are described in detail in this thesis. Practical part deals with the team orienteering problem applied to a real task, specifically a visiting of 23 attractions in the New York in different number of days. The solution is found by optimization program Lingo 90 and by heuristic of Chao el al. Heuristic algorithm was implemented in programming language Visual Basic for Application. A comparison of the results is described at the end of the practical part.

The task of the diploma thesis named VBA and Maple Application on Process Engineering Problems is to show the possibilities of using these programming languages for various engineering tasks. Particularly the programming language Visual Basic for Application (VBA), which is a part of MS Office package, is very little used in practise. That´s why this thesis solves the complex task of a furnaces design process; the topic was reccomended by the supervisor prof. Ing. Josef Kohoutek, CSc. Specifically, the thesis deals with calculations of heat transfer and optimization of the height of extended surfaces of tubes in the convection section of process furnaces. The entire task is elaborated in VBA and runs in Excel. After entering the input information, the created program first calculates the size and heat output of the convection section, but it can also optimize the height of extended surfaces in different parts of the convection section and thus minimize investment costs.
