Land contamination is an acknowledged problem around the world due to its potentially adverse impacts on human health and the environment. Specifically in Europe there are estimated to be 2,500,000 potentially contaminated sites. The risk that contaminated sites pose is investigated by risk assessments. The methods and the models though used in risk assessments, vary both on a national and an international level. In this study, the risk assessment methods and models for polluted soils used in Scandinavia and issued by the Environmental Protection Agencies were compared. The comparison aimed to (i) identify similarities and differences in the risk assessment methodology and risk assessment methods and to (ii) investigate to which extend these differences can impact the results of the models and the implications regarding mitigation measures. The method and model comparison showed that Sweden and Norway have great similarities in assessing risks for contaminated soil. However, there are differences with Denmark on a conceptual level. When a common hypothetical petrol station with 20 soil samples was assessed, the results and the conclusions of the three risk assessments were quite different; the site was seen as posing risk to human health with the Danish model when complied with the quality criteria issued by the Norwegian model. The Swedish risk assessment concluded that the contaminant concentration in 3 out of 20 samples was potentially harmful for the environment but not for human health. The demonstrated divergence of the conclusions of risk assessments has major implications and shows great interest for mainly four groups: Land-owners who may be called to cover the expenses for remedial action. Consultants and companies who perform risk assessments and land remediation. The countries that have to meet national and international environmental goals and can also share/ or cover the cost for remedial action. The people exposed to such environments that could be deemed as potentially harmful by a neighboring country. The study was conducted in collaboration with URS Nordic.

The thesis concerns with measurement of processes of support and maintenance of a specialized information system for petrol stations. It is a system for support of retail sale of fuel and other non-fuel goods. As the main objective of the thesis was selected design of set of metrics for measurement of these processes based on multidimensionality principle. It means that dimensions and indicators are designed separately and a set of recommended metrics is based on their combinations. It is possible to get additional metrics using other combinations. The theoretical basis of the thesis is the ITIL library -- which is an internationally respected standard for IT service management -- and metrics designed in other literature and diploma theses. The designed metrics are adapted for the analyzed environment and service information system, however, they should be usable in other environments as well. Selected metrics were implemented to the service information system and measured in a relatively wide sample of input data. This allowed evaluating usability of the metrics and comparison of the threshold values with the measured ones. The relationship of metrics and service agreements (SLAs) is described in the end of the thesis. Specific metrics suitable to be incorporated to SLA were designed including a real-life example.

This thesis deals with the evaluation of risks of business development proposals ZEVOS a.s. acting on the fuel market. The thesis is divided into three main parts, the first part describes the theoretical knowledge. In this section are shown and described methods of dealing with the internal and external surroundings of the company. In the second part, which deals with the analytical part, the methods used to assess the current situation in the market where the company operates. The third part provides a proposal for the development of business solutions and financial investment return.

Degalinės yra vienas iš pavojingesnių aplinkos taršos šaltinių, nes jų aplinkoje į atmosferą išsiskiria įvairūs tiek aplinkai, tiek žmogaus sveikatai pavojingi teršalai. Šio tyrimo tikslas – nustatyti oro taršos lygį degalinės aplinkoje bei gretimose jos teritorijose, pasirinkus tipišką priemiesčio degalinę. Tyrime buvo nustatinėjamos azoto dioksido, sieros dioksido, benzeno, formaldehido, bei kietųjų dalelių koncentracijos aplinkos ore. Atlikus tyrimus nustatyta, kad didžiausios lakiųjų organinių junginių bei dujų koncentracijos yra degalinės operatoriaus darbo vietoje, kur azoto dioksido (2,03 ppm), benzeno (1,52 ppm) ir formaldehido (1,43 ppm) koncentracijos ore viršijo didžiausias leidžiamas koncentracijas darbo aplinkoje. Degalinėje, lauke visų tirtų lakiųjų organinių junginių ir dujų koncentracijos viršijo ribines vertes aplinkos ore. Taip pat nustatyta, kad už degalinės teritorijos teršalų koncentracija ore padidėja likus 100 m iki degalinės. Kietųjų dalelių tyrimai parodė, kad degalinės aplinkoje daugiausiai vyrauja 0,3 – 0,5 µm dydžio dalelės. Taip pat degalinės teritorijoje, lauke buvo viršyta didžiausia leidžiama kietųjų dalelių koncentracija aplinkos ore. / A petrol station is one of the most dangerous sources which are known to contribute greatly to the pollution of the environment due to normal pollutants they emit into atmosphere. The aim of the research is to assess the level of the pollution in the surroundings of a particular city petrol station as well as in the territory of the nearly by petrol stations. A research has been carried out to measure the amount of nitrogen dioxide, nitrogen monoxide, sulfur dioxide, benzene, formaldehyde and particulate matters concentrations in the air. After carrying out the research it was found out that the largest concentration of volatile organic compounds and gases was discovered in the working place of the operator of the petrol station where the concentrations of nitrogen dioxide (2,03 ppm), benzene (1,52 ppm) and formaldehyde (1,43 ppm) in the air exceeded all the limits allowed in working places. The concentration of gases and volatile organic compounds in the station and outside it exceeded the marginal value of in the air. Research also proved that the concentrations of pollutants increase in its amount 100 m around the petrol station. The test on particulate matters shoved that the prevailing size of the particulate matters was about 0,3 – 0,5 µm and their concentration highly exceeded the permitted amounts in the territory of the petrol station.

Subject of this diploma thesis is to formulate development strategy for a company operating petrol station, hotel and restaurant. Specifically, it is about executing strategic analysis, analysis of internal and external factors to identify strengths and weaknesses of the company. Implementation of the proposed measures aims to improve company’s existing market position and secure its functioning even with major changes of environment.

The main goal of this thesis is to create business plan for the establishment of the petrol station operating as BENZINA franchise. Entrepreneurship, requirements of the business plan, franchising and definition of used analysis are described in the theoretical part. Necessary analyses are performed in the analytical part. Suggested business plan and schedule of its implementation are described in the last part of this thesis.

The task of my diploma work is the study of the parking area on the motorway D1 near Vyškov. This place will be connected with the motorway D1 between the present exit Vyškov – West (226) and Vyškov – East (230/1) in the direction to Kroměříž. The parking area (the parking place, the petrol station, the restaurant) and the truckpark will be designed with the reason of the high intensity of cars and lorries on the motorway D1 and with the reason of the lack of the parking places for the lorries.
