The content of the thesis is to familiarize students with module PLC Siemens LOGO! and its practical use in teaching courses in the subjects as automation, electro-nics and mechatronics at vocational secondary schools. The content is focused on the basic description of the development and graphical environment and its use in practical problems solving. In the practical part of the proposals there are worksheets for pupils with the design of pupils´ simple tasks. After studying this text and the compilation of practical problems, the student should be capable of independent operation with module PLC Siemens LOGO! and implementation of complex applications.

The Company Siemens Industrial Turbo Machinery AB manufactures and launches in operation among other things gas turbines, steam turbines, compressors, turn-key power plants and carries out service for components for heat and power production. Siemens also performs research and development, marketing, sales and installations of turbines and completes power plants, service and refurbish. Our thesis for the engineering degree is to develop an automatic status log which will be used as a tool to control how the status of the machine is before and after technical service at gas turbines. Operational disturbances will be registered in a structured way in order to get a good possibility to follow up the reliability of the application. An automatic log function has been developed and will be activated at start, stop and shutdown of the turbine system. Log files are created automatically and get a name with the event type, the date and the time. The files contain data as timestamp, name, measured values and units of the signals which are going to be analyzed by the support engineers. They can evaluate the cause of the problem using the log files.

A valia a partir do material levantado na empresa pela metodologia das quatro vozes, quais os efeitos indesejáveis segundo a teoria das restrições que se pode encontrar no referido material e verifica a existência de restrições não identificadas e não contempladas. Faz uma análise crítica do processo sob o ponto de vista da teoria das restrições.

Sund Birsta, ett företag som utvecklar och levererar maskiner och utrustning till stålindustrin världen över, håller på att standardisera operatörspanelerna till deras samtliga maskiner. Maskinen stångräknare har inte en HMI som följer det nya gränssnittet utseende- eller funktionsmässigt. Målet med arbetet var att utveckla ett HMI med hög användbarhet som följer Sund Birstas riktlinjer och presenterar all information på 5 skärmar. En litteraturstudie har genomförts för att finna svar om vilka krav som ställs på ett HMI för att nå hög användbarhet. De designkriterier som följts är synlighet, återkoppling, begränsningar, konsekvent och affordans. HMI:t är skapat för panelen Siemens Basic KTP1200 och utvecklat i programmet Tia Portal. Resultatet visar att huvudskärmbilderna för HMI:t har skalats ner från 21 skärmbilder till 5. Det utvecklade HMI:t följer samma gränssnitt som en annan maskins operatörspanel inom maskinfamiljen med skillnader i maskinernas unika funktioner. Det används mindre tillgängligt minne i HMI:t med den nya HMI-lösningen dock innebär den nya lösningen en ökad arbetsminnebelastning jämfört med den tidigare lösningen. Då mindre tillgängligt minne används så öppnar det upp för utbyggnadsmöjligheter eftersom HMI-panelens utrymme är begränsat dock kan responstiden påverkas av ökad arbetsminnebelastning. / Sund Birsta, a company that develop and deliver machines and equipment for the steel industry around the world, are in the process of standardize HMI-panels for all their machines. Their machine, bar counter, don´t have an HMI that follow their new interface regarding appearance and functionality. The goal with this study was to develop an HMI with high usability that´s following the guidelines of Sund Birsta and present all information on 5 screens. A literature study has been done to find answer on the demands for an HMI to reach high usability. The design criteria’s that´s been complied are visibility, feedback, restraints, consistency and affordance. The HMI is created for the panel Siemens KTP1200 in the software Tia Portal. The results show that the sub screens for the HMI has been reduced from 21 to 5 screens. The developed HMI are following the same interface design as the HMI for another machine in the same machine family, with differences in the machines unique functionality. The new HMI are using less memory to load the screen but are using more work memory in comparison to the old HMI.   When less available memory is used it opens for expansion opportunities as the available memory is limited, however, the response time may be affected by the increased work memory usage.

This thesis is focused on communication strategy of the Siemens company with emphasis on the communication activities of the Czech companies of the Siemens group and on the particular marketing campaign. The theoretical part explains the term "communication strategy" and describes the process of marketing communication and various models referring to the marketing communication. Furthermore, it characterizes particular tools of the communication mix and also deals with marketing research. The practical part provides general information about the Siemens company and a description of the communication activities of the company which are focused on the increase of the brand knowledge and strenghtening of the company image. This part also deals with the changes in the communication strategy after 2003 and the characterization of the Czech marketing campaign "We Like Being In the Czech Republic". The evaluation of the effects of the performed changes and the marketing campaign for the image of the Siemens company is the content of the final chapter. This evaluation results from the findings of the image analyses carried out by an independent research agency.
