1. A system approach to predicting the risk of defects and failures with low probability of occurrence in water management structures

   Water management structures are significant construction works whose damage poses a serious risk to their functionality as well as the safety of the residents and their surroundings. Risk analysis including its identifiction and assessment is a commonly applied system approach whose aim is to remove or minimize the negative impact. However, there may appear unexpected risk with low occurrence probability (so called black swans) which may have a serious impact. The damage may be financial, material or to the health or lives of the residents. Currently, in risk analysis related to the construction and operation of water management structures a methodological procedure is missing that would also contain the analysis of unexpected phenomena called black swans. In dealing with this issue, it is necessary to increase the demands on the safety and quality of structures, to decrese their susceptibility to failure and to increase the resistence of these buildings considering the changing surrounding conditions. The aim of the doctoral thesis will be to propose a methodology of a complex analysis execution including qualitative and quantitative approaches in identifying and assessing the risk of the occurrence of defects and failures in water management structures connected with the occurrence of the so called black swans. This should be based on a thorough analysis of the current approach to the assessment of defects and failures, their prediction and the application of not only preventive measures.

2. Methodology of assessing the defects and failures in wine cellars

   Based on research on wine cellar construction systems in the Czech Republic and abroad an analysis will be carried out of the advantages and disadvantages of each construction system both from the point of view of historical significance and with respect to the current state. Subsequently, individual defects and failures that occur most frequently in wine cellars will be examined by trying to discover the cause of the defect (failure), the possibilities of its correction, calculating the cost of the defect (failure) correction and if the defect cannot be repaired, the impact on the total price of the structure will be assessed. The methodology will include a recommended procedure for examining wine cellars in relation to valuation focusing on finding the most frequent defects occurring in wine cellars. Part of the output will be creating a database of the most frequent defects and failures categorized according to seriousness and whether they can or cannot be repaired. At the same time, data on the real age of the wine cellars will be collected and subsequently assessed in terms of mutual connection and the surrounding effects influencing their lifespan. The knowledge gained will be used in practice for valuation, especially for estimating the identified price or a modification of the valuation regulation will be recommended.
