Cluster analysis as a tool for classification of objects
Budilová, Šárka ; Löster, Tomáš (advisor) ; Šulc, Zdeněk (referee)
Cluster analysis is a popular method of multivariate statistics. Based on mutual similarities between objects this method is able to classify and divide objects into several groups or clusters. The results of the clustering can be different by using different methods, measures of distance and procedures. The main aim of this thesis is to compare the results of several methods of cluster analysis with the known classification of classes from the original data file. In total, there are 15 data files, which were analyzed and each of them contained known information about the right allocation of objects in groups. The success of clustering of each method was calculated by comparing the known classification of classes and resulted clusters. In addition to the comparison of individual methods of cluster analysis was compared the impact of standardization and correlation to the success of each method. To reflect the distance betweeen the objects within each clusters, squared Euclidean distance was used. The results of this thesis point out that better success of clustering were achieved in the case of correlated variables in data file. The succes of clustering was higher about 2 percent points than in the case when correlated variables were deleted from data set. The methods divided 69,8 % objects before standardization and 70,8 % objects after standardization. The results also show a large importance of standardization in the case of Ward´s method. After standardization this method rank the most objects into correct classification classes and were more succesful, about nine percent points. In the case of correlated variables is the succes of the method 76,4 %. Standardization positively influences also centroid method and the method of farthest neighbour. Median method, nearest neighbour method and the method of average linkage achieve higher success of clustering in the case of original, nonstandardized variables (uneven variables).

Optimisation of the selected manufacturing process in the company Car manufacturing.
Šmídová, Pavla ; Svobodová, Hana (advisor) ; Rosa, Alexandr (referee)
This thesis deals with the optimisation of the selected manufacturing process. The aim is to analyse the effectiveness of the selected welding and assembly lines. Another objective is to do a detailed analysis for the line with the lowest efficiency in terms of cycle time and the Overall Equipment Effectiveness and calculate the lost production time due to availability, performance and defects. The third objective is to identify possible measures leading to higher utilization of manufacturing line and to propose a possible implementation. The theoretical part is based on the literature examining the term standardization, the norms of labour intensity, the cycle time, the Total Productive Maintenance and the calculation of the Overall Equipment Effectiveness. In the practical part the profile of Car manufacturing is being presented, the analysis of secondary data to calculate the Overall Equipment Effectiveness is being done and the appropriate manufacturing line for the innovative plan is being selected. Furthermore, the analysis of secondary data regarding the effectiveness of the using time of the manufacturing line is being done, the calculation of the Overall Equipment Effectiveness and the collection of primary data is being carried out. Subsequently, the problematic spots of the manufacturing line are being found and the possible measures leading to higher efficiency of manufacturing line are being proposed.

Marital status as a differentiating factor in demographic behavior
Nedomová, Radka ; Pechholdová, Markéta (advisor) ; Nývlt, Ondřej (referee)
Diploma thesis explores the diversity of demographic behavior depending on marital status and is aimed at summarizing the effect of marital status on demographic behavior as a whole. The first phase deals with the concepts of impact of marital status on demographic behavior, explains the theory of selection and causality and outlines the historical development of nuptiality and divorce by using basic indicators. The practical part is based on the results of Population and Housing Censuses during the period 1961-2011 and compares the changes in the structure of the Czech population by sex, age and marital status between censuses. Emphasis is placed on the period after 1990. Furthermore, in separate chapters is mapped out how marital status affects demographic processes of fertility, abortion, nuptiality and mortality. In the case of fertility exploration is emphasized increasing extramarital fertility, as more and more children are born outside marriage, especially to single mothers. By using age-specific and standardized rates are analyzed changes in the development of individual demographic processes between censuses for all categories of marital status. Standardization of mortality for the years 1961, 1970 and 1980 is made on the basis of the formation of shortened life tables and the subsequent modeling of mortality at higher ages. In connection of changing structure of the population by marital status, as the proportion of unmarried and divorced people is growing and the share of people living in a marriage is decreasing, is judged attitude of the Czech public toward marriage and family according to surveys results available.
