Implementation of the Subtructure of an Apartment Building
Teplý, Tomáš ; Nečasová, Barbora (referee) ; Liška, Pavel (advisor)
The subject of this bachelor's thesis is the constructional-technological solution of the substructure of an apartment building in Zlin. It is an object with five floors and a basement with garages. The building is based on drilled piles. The bachelor's thesis includes a construction plan with a site equipment, technological procedure of earthworks and drilled piles. A set of machines, a quality control, a budget and a time schedule have been processed for this technological phase. During the building process it is cared about work safety and environment protection.

Analysis of Competitors Fight in Business Technology Sector
Kreps, Jakub ; Špíšek, Jiří (referee) ; Bartes, František (advisor)
The thesis analyses competitive environment of suppliers of concurrent quality control technology in industrial enterprises and research laboratories. The thesis provides concepts for a creation of competitive advantages and related higher evaluation of costs and diferentiation than competition. Further it compares technologies from various manufacturers, comparing economical and technical parametres. The evaluation of results follows a presentation of approachs to achieve the most efficient competitors fight management. The thesis also include prognosis of future conditions in the business technology sector on Czech and Slovak market and concept of an appropriate format of effective competitive intelligence. In conclusion there is a presentation of a quality and quantity concept evaluation with emphasis on economic gain of presented solution.

Deep Neural Networks for Defect Detection
Juřica, Tomáš ; Herout, Adam (referee) ; Hradiš, Michal (advisor)
The goal of this work is to bring automatic defect detection to the manufacturing process of plastic cards. A card is considered defective when it is contaminated with a dust particle or a hair. The main challenges I am facing to accomplish this task are a very few training data samples (214 images), small area of target defects in context of an entire card (average defect area is 0.0068 \% of the card) and also very complex background the detection task is performed on. In order to accomplish the task, I decided to use Mask R-CNN detection algorithm combined with augmentation techniques such as synthetic dataset generation. I trained the model on the synthetic dataset consisting of 20 000 images. This way I was able to create a model performing 0.83 AP at 0.1 IoU on the original data test set.

Statistical Analysis of Real Process Scrap
Širjovová, Zuzana ; Karpíšek, Zdeněk (referee) ; Bednář, Josef (advisor)
Quality, as well as stability of processes check is nowadays gaining on its significance. The main driving force of its increasing importance is the rapid expansion of series production. Large-scale manufacturing processes are concerned, in terms of the number of operators, direct and indirect influence on rejects, but also on process stability. There are several quality characteristics, defined by utility properties, that can be easily measurable (linear dimensions, solidity, elongation, humidity, concentration) or directly immeasurable, mostly subjective (fragrance, taste, color, comfort while using, appearance). Statistical Process Control-SPC features the preventive tool of quality control, because based on the early detection of significant divergences of the process from the predetermined level, it is possible to execute interventions in the process with the aim of maintaining the acceptable and stable level and improving the process. This manufacturing process check will be the topic of my thesis. At first, Shewhart's control charts analysis will be done to determine strong process instability. Consequently, analysis will be carried out in test chi-square, used to determine the influence of each factor on the process of stability (operators, type of shift, type of product, type of defect on the product). All the practical part will be processed in statistical software MINITAB15. The thesis will be complemented by the findings from the examination of the features of interval estimates of parameter p for binomial distribution - numeric stability in the various statistical software (specifically Minitab 15, Statistica, Matlab 7.8.0). Master's thesis was supported by project from MSMT of the Czech Republic no. 1M06047 Center for Quality and Reliability of Production.

Necessity of quality management
Pavlíček, Michal ; Kružík, Michal (referee) ; Fiala, Alois (advisor)
Task of the thesis is to develop a literature search on the topic: „Necessity of quality management“. The paper defines the concept of quality and quality control. These are basic concepts for this extensive and still very dynamically developing field. I tried to create objektive look on these questions and in the end think about necessity or uselessness of quality management systems.

Machine vision for the check of moldings
Grepl, Pavel ; Pavlík, Jan (referee) ; Vetiška, Jan (advisor)
Bachelor's thesis deals with the design of arrangement of an automatic inspection unit for specified products using machine vision. The theoretical part is focused on specification of the inspection system and research in the area of machine vision components, such as cameras, lens and illumination. The practical part consists of multiple possible arrangements of the inspection unit. Solutions of the chosen arrangements, including programming and testing the application using Vision Assistant software. Finally, economic evaluation of the automation of the quality inspection using machine vision has been made.
