Statistics Control of Process Described by Attributive and Continues Variable
Blachut, Vít ; Martišek, Karel (referee) ; Bednář, Josef (advisor)
The principle of the statistic hypothesis testing is explained in the first part of this bachelor thesis. Specifically, there is explained into depth the independency test for discrete probability distribution and its possible application on the real data. The second part of this bachelor thesis is dedicated to the monitoring of the stability process, using the control charts that are primarily used for assessing the process to be stable or beyond control. The focus is especially on chosen construction diagrams deduction. The suitable diagrams are then applied on the real process data, and later there are implemented tests of definable causes. The bachelor’s thesis was supported by project from MSTM of the Czech Republic no. 1M06047 Center for Quality and Reliability of Production.

Statistics Control of Process Described by Attributive and Continues Variable
Svobodová, Hana ; Popela, Pavel (referee) ; Bednář, Josef (advisor)
This thesis aimes at approaching the problem of control diagrams. The first part summarizes the theoretical knowledge about the control diagrams, including their sorting based on the type of the monitored quantity. The different types of diagrams are described in detail. The second part deals with the practical use of control diagrams using actual data. Tests of definable causes are used on these data, and the causes of failure are sought. The key is to assess process stability.

Use of Statistical Methods for Data Processing
Hladiš, Lukáš ; Ing.Churý Tomáš (referee) ; Doubravský, Karel (advisor)
This thesis aims to evaluate a new manufacturing process by using statistical methods SPC. In the theoretical part provides the basic methods and rules applied in the assessment of control charts. The next part evaluates the current state of the company Hanhart Morkovice s.r.o. analysis and production of coils. The analytical part deals with control charts for reference and quality characters using statistical software process capability indexes and control charts. Based on information from the analytical part, conclusions are drawn and designed for long-term steps using established methods of SPC for quality characters.
