Implementing of SPC into production process
Letáček, Jiří ; Koška, Petr (referee) ; Fiala, Alois (advisor)
This graduation thesis is concerned with implementing the SPC (Statistical process control) to the process plan. The aim of this thesis is an analysis of present status of manufacture laths bending and a selection of useful methods, which is possible to apply in a company processes. The main reason for SPC implementation is continual improvement of quality in manufacturing concern. The theoretical part of thesis consist of bending description, control of process quality, quality control instruments and errors in measurement. In practical part is described an actual status of manufacture and a solution of query.

Evaluation of Polymer Separation System Purifier N 1024 device efficiency
Duliková, Michaela ; Charvátová,, Michaela (referee) ; Čáslavský, Josef (advisor)
In this Diploma Thesis the recycling of the PET bottles in the company PETKA CZ, a.s. is under focus. Thesis describes the Italian technology AMUT designed for physical recycling of the PET bottles. The primary goal is the quality of the final recycled product, PET flakes, particularly in the context of undesirable admixtures such as PVC, other polymers and impurities. Due to the deteriorating quality of the PET flakes the equipment Polymer Separation System Purifier N 1024 has been tested, which had significantly reduced admixtures in PET flakes. As it turned out, the current procedures for solving problems with the PET flakes quality are no longer sufficient.

Harmonized FMEA analysis
Riabov, Mikhail ; Szendiuch, Ivan (referee) ; Novotný, Radovan (advisor)
The target of the diploma thesis on „Harmonized FMEA analysis“ is to familiarize with principles of quality planning and studying the theory of existing APQP tools. Another goal is to learn the basics of the new manual of harmonized FMEA analysis and discover some available SW tools for project support. This diploma thesis will be focused mainly on DFMEA analysis of traction assembly and the concept of changing to new harmonized version from VDA/AIAG will be explained. This concept meets the requirements for clear and comprehensible output required by the manufacturer, supplier, and customer. The diploma thesis is elaborated as a detailed clear guide for easier processing of FMEA according to the new manual.

Process Optimization Project to implement an Integrated Management System
Moravcová, Gabriela ; Milichovský, Miloš (referee) ; Videcká, Zdeňka (advisor)
First part is an introduction into this thema, followed with second part, which clarifies (describes) the whole process from receiving the demand through part development till serial production approval. Third part describes the claim procedure, including all methods, used for solving the problems and followed with short analyse of production centres activities and sorting the claims by causer. All claims are given factors, which may cause claim occurence. Every factor is given by specific importance (weight) and the achieved data are evaluated. In final part I suggest the corrective actions.

Statistical analysis in quality management
Chlebounová, Klára ; Knobloch, Josef (referee) ; Zahálka, Jiří (advisor)
The goal of this thesis is to create a literary research on the methods of statistical data processing in the field of quality management and to make their overview along with the possibilities of using them. A practical example shows how to determine manufacturing process stability and qualification determining, using the Shewhart’s control chart and capability indexes. This methodics should serve as a guideline for manufacturing process evaluation. As a brief summary of generally used statistical data processing methods, this thesis should serve all, who are engaged in quality management.

The Application of Fuzzy Logic for Rating of Suppliers for the Firm
Olšová, Renata ; Doskočil, Radek (referee) ; Dostál, Petr (advisor)
Cílem této diplomové práce je návrh vhodné metody, jak vyhodnotit dodavatele modelů letadel a leteckého příslušenství holandské společnosti Aviation Megastore. Tato polečnost existuje na trhu již více než 25 let a má více než 170 dodavatelů po celém světě. Proto vznikla potřeba jednotlivé výrobce a distributory ohodnotit a zvážit jejich vývoj během jednotlivých let, případně u některých vybraných dodavatelů zvážit vzhledem k neuspokojivým výsledkům možnost ukončení spolupráce. Pro vyhodnocení bude použit program MS Excel a MATLAB.
