Impact of competitive pressures, ever-increasing investor demands and the unstable economic situation forces construction companies to more effective preparation and management of contracts. The subject of this thesis is the preparation and management of construction contracts in the construction company. The theoretical part is devoted to the description management by project and its tools, supply activities and supplier preparation of construction. Theoretical explanation matters of project management is followed by practical demonstration of the selected job.

The diploma thesis deals with the issue of managing a construction contract in a construction company. The aim of the thesis is to describe preparation and managing of a construction contract. The theoretical part concerns with description of project managing and its tools, supplier's duties and construction preparation. The out come of the thesis is a practical demonstration of a chosen example.

The thesis describes the project management of a construction contract in a construction company from the supplier's point of view. The work includes a theoretical and practical part. The theoretical part describes important definitions and knowledge, which are then used to create a practical part. It deals with the preparation and management of a specific construction contract called "Reconstruction of the sports hall Otrokovice" with the help of methods and procedures that the issue offers.

This diploma thesis solves problems of construction orders management. The key to successful business and stable position in a competitive market is the way of planning, managing and quality processing of construction orders. The aim of this diploma thesis is to describe and analyze the management of a construction order in a selected company, in my case ARCHATT, s.r.o. I also deal with this in this work, namely for the specific order Oprava Severního parkánu a hradeb of Prague Castle. The content of the work is a processed documentation of the supplier's preparation for this order and a detailed description of the entry of construction workers to this daily guarded building.

This diploma theses deals with the challenges of a project management in a particular construction company that handles projects on daily basis. I focused on the analysis of a particular project in this company, that has been successfully implemented. This analysis served as a starting point for the designing of the changes, as well as a devising a tool that simplifies the set up of the changes into practice. Selected problem was solved by comparing the project management methodology in the project with the project management practices officially proposed in the literature. Tool design was carried out in the environment of Microsoft Excel. I managed to design a tool in which the shortcomings are treated the way that facilitates their implementation into practice, especially by using an easy environment and outputs well-arranged for the user. This tool is therefore mainly used to eliminate the identified shortcomings and thus to facilitate and simplify project management in practice.

This doctoral thesis is focused on metrics and the criteria for socio-technical system diagnostics, which is a high profile topic for companies wanting to ensure the best in product quality. More and more customers are requiring suppliers to prove reliability in the production and supply quality of products according to given specifications. Consequently the ability to produce quality goods corresponding to customer requirements has become a fundamental condition in order to remain competitive. The thesis firstly lays out the basic strategies and rules which are prerequisite for a successful working company in order to ensure provision of quality goods at competitive costs. Next, methods and tools for planning are discussed. Planning is important in its impact on budget, time schedules, and necessary sourcing quantification. Risk analysis is also included to help define preventative actions, and reduce the probability of error and potential breakdown of the entire company. The next part of the thesis deals with optimisation problems, which are solved by Swarm based optimisation. Algorithms and their utilisation in industry are described, in particular the Vehicle routing problem and Travelling salesman problem, used as tools for solving specialist problems within manufacturing corporations. The final part of the thesis deals with Qualitative modelling, where solutions can be achieved with less exact quantitative information of the surveyed model. The text includes qualitative algebra descriptions, which discern only three possible values – positive, constant and negative, which are sufficient in the demonstration of trends. The results can also be conveniently represented using graph theory tools.
