The diploma thesis deals with the issue of designing a part of the information system for passenger. The proposed system is aimed at providing clear information about driving a recreational-tourist train. The outcome is a web portal that processes data about the train ride and then presents it to potential customers.

The aim of this thesis is to create a custom application to simulate production lines. The first part explains the main reasons, benefits and current trends in the field of virtual commissioning and describes several simulation tools and engineering tools from Siemens. The second part is devoted to a detailed description of features, capabilities and application interface of the PLCSIM Advanced simulation tool. The third part is devoted to design and realization of the custom simulation application, which can be used for create conveyor lines and validate user PLC program in cooperation with PLCSIM Advanced tool. This simulator was created using Unity3D game engine and C# programming language. In the last part of the thesis, a simple simulation task is created in the simulator and is tested using PLC program and visualization created in the TIA Portal engineering framework.

The aim of this thesis is to analyze the problem of rubber production lines and their possible elimination. The next step is the point that will be devoted to the design of a possible improvement of the line to increase efficiency, the software I worked with will be described, the hardware that was used, and in the final part the source code for the control system, which is designed for very precise frame positioning in one part of the line.

This master’s thesis deals with a total concept of decentralized control system for process control by means of PLC SIMATIC. This concept is demonstrated on a model of a portal crane in the introductory chapter. The second chapter is focused on industrial communication network PROFIBUS. Different types of this network and ways of communication are described. The third chapter is concerned with industrial communication network PROFINET (Industrial Ethernet). Different types of this network and ways of communication techniques are described. The next chapter presents components of Siemens company, which are necessary for creation of demanded control system. The following part describes the programming facilities for STEP 7 programs - Simatic Manager, Micro/WIN and WinCC flexible. It contains creation of the control system including communications on the networks.

SEO - Search Engine Optimization, determine ways and methods to create a web page so that search engine can incorporate it into the search results. Its great advantage is the durability of results and it results to high return of an investment. This work talks about the basic and most important SEO parameters. It propose which parameters are most important to be tested and best way of testing. Most of publishers often do not know that their sites are in terms of SEO totally inaccessible. With portal they can make their sites quickly and easily tested and find out where are their main weaknesses. When parameter has been tested SEO Portal determines how to correct errors. An important feature of portal is simplicity. After entering the address of the site they can see clearly arranged results.

The work presents a control system for energy savings using the recycling of steam in autoclaving process of porous blocks. This work describes a manufacturing process of porous. The control system is based on programmable controllers from Siemens series S7-300, then is applied to the TIA Portal software for the programming of these units. Lastly, the work comprises of process simulation, control system and its subsequent visualization.

This master's thesis deals with a company information system called Enterprise Resource Planning (ERP) which is supplied by the SAP. First, the thesis surveys historical development in the area of ERP. Next, it studies a current SAP ERP product which is based on a new SAP NetWeaver technological platform. The thesis focuses on the possibilities of company-processes integration into SAP NetWeaver Portal environment and it introduces certain examples for exploiting its potential in practise.

The area of small and medium enterprises (SMEs) is an important factor, in which many see a promise of improvement of the economic situation. It is a well-founded request, and as shown in many advanced economies, this segment is an important part of economy. My thesis involves one of these situations, where a starting entrepreneur, with low capital investments, is looking for ways how to achieve his market goals and how to support business processes with the help of information technology (IT). The IT supported business model here, will be a model, where the main distribution channels are realized with help of IT technologies. With this distribution channel relates the use of social network services as a marketing tool enabling a development of a company and an effective but not capital-intensive tool designed to realize the business targets.

Business plan is important and undivided part of company management and of business planning. My master’s thesis points on usefulness of business plan as a medium for beginning entrepreneur, with low capital base, which is searching concepts how to push his visions trough in market. The master’s thesis introduces concrete practical example of creation and maintenance of new generation web portal. Description of usage in marketing and business point of view. This plan also contains concepts of company structure and plan of company expansion in three years term. Parts of the document are estimations of portal and company costs and also estimations of revenues. Document is draw up for multiple usage of business plan, not only for business visions presentation, but also as a concept for obtaining of financial resources from investors.

The thesis deals with potentialities of a company, whose activities are focused in the intrnet environment. Together with maintaining a fisherman portal, the company is involved in producing instructional and narrative movies with fishing themes. In the thesis, different ways to approach special interest groups are discussed, as well as different means of advertising services to these groups. The thesis concludes in several proposals, that may result in the company growth.
