The Study of Systém and Process optimization of Service operation
Prokeš, Viktor ; Havlásek, Roman (referee) ; Jurová, Marie (advisor)
This thesis is oriented on the automotive industry with the focus on the domestic producer of the vehicles – the Škoda Auto Company. It describes the subject of business in the mentioned company and subsequently it refers to the current trends of the automotive market in the Czech Republic. On the basis of the analyses` results of the after-sales services allied with usage of the Škoda-products it will propose their possible future progression. Thereinafter will the thesis concentrate on the description of the existing after-sales processes focused on the „through-pass“ of the vehicle through the authorised Škoda Auto service. It deals with the analysis of the service systems in detail using the tight cohesion of them. Modern technologies used in the current vehicles put significantly higher demands on their maintenance, which call for the continual optimization of the service processes with the maximal utilisation effort of the feedback. The appropriate personnel have become the necessity. For these purposes it will be recommended the introduction of the electronic multipurpose memory devices intended for the data collection. In the next step will the after-sale-service process be described with the focus on the usage of these electronic memory vehicle-keys with the reference to the procedural simplification of the maintenance operations. The final part of the thesis will evaluate the general contribution of the proposed resolution for the service processes as well as their users.

Solar cell non-destructive analysis
Černý, Michal ; Škarvada, Pavel (referee) ; Macků, Robert (advisor)
This thesis briefly analyse contemporary situation of photovoltaic systems and their actual developemenet. It shows a typical properties of most produced up-to-date types. Decision point of this thesis consist in nondestructive analyse of monocristalic unijunction solar cells. It describes two main diagnostic aproaches. First – through the use of measuring of VA characteristics, second – through the use of measuring noise characteristics. With selected samples are performed experimental measurements and estabilished basic parameters. In case of drone analysis considerably attention is devoted to experimental equipment for automatized measuring of spectral power density. This experimental equipment is consequently used for measuring some samples where we can observe microplazmatic noise.

The Study of Implementation of Innovated Products in Production Process
Molík, Tomáš ; Šifalda, Martin (referee) ; Jurová, Marie (advisor)
This student thesis deals with a problem of manufacturing and competition ability of the joint stock company ZVVZ in the range of its manufacturing program - radial fans. The thesis compares the present and the innovated type of small radial fans from the view of manufacturing technology and manufacturing costs. The study comes out the technological documentation and demand forecast of future market. Finally the thesis summaries conditions which are necessary for the successful entrance of the innovated type of radial fans into the manufacturing process.
