In this thesis, we provide a set of comprehensive models and methods to efficiently execute multiway spatial join queries in distributed systems. We introduce a cost-based optimizer that is able to select a good execution plan for processing such queries in distributed systems taking into account: the partitioning of data based on the spatial attributes of datasets; the intra-operator level of parallelism, which enables high scalability; and the economy of cluster resources by appropriately scheduling the queries before execution. We propose a cost model based on relevant metadata about the spatial datasets and the data distribution, which identifies the pattern of costs incurred when processing a query in this environment. We formalized the distributed multiway spatial join plan scheduling problem as a bi-objective linear integer model, considering the minimization of both the makespan and the communication cost as objectives. Three methods are proposed to compute schedules based on this model that significantly reduce the resource consumption required to process a query. Although targeting multiway spatial join query scheduling, these methods can be applied to other kinds of problems in distributed systems, notably problems that require both the alignment of data partitions and the assignment of jobs to machines. Additionally, we propose a method to control the usage of resources and increase system throughput in the presence of constraints on the network or processing capacity. The proposed cost-based optimizer was able to select good execution plans for all queries in our experiments, using public datasets with a significant range of sizes and complex spatial objects. We also present an execution engine that is capable of performing the queries with near-linear scalability with respect to execution time. / A multi-junção espacial é um tipo importante de consulta usada no processamento de dados espaciais e sua execução eficiente é um requisito para mover a análise de dados espaciais para plataformas escaláveis, assim como aconteceu com dados relacionais e não estruturados. Nesta tese, propomos um conjunto de modelos e métodos para executar eficientemente consultas de multi-junção espacial em sistemas distribuídos. Apresentamos um otimizador baseado em custos que seleciona um bom plano de execução levando em consideração: o particionamento de dados com base nos atributos espaciais dos datasets; o nível de paralelismo intra-operador que proporciona alta escalabilidade; e o escalonamento das consultas antes da execução que resulta em economia de recursos computacionais. Propomos um modelo de custo baseado em metadados dos datasets e da distribuição de dados, que identifica o padrão de custos incorridos no processamento de uma consulta neste ambiente. Formalizamos o problema de escalonamento de planos de execução da multi-junção espacial distribuída como um modelo linear inteiro bi-objetivo, que minimiza tanto o custo de processamento quanto o custo de comunicação. Propomos três métodos para gerar escalonamentos a partir deste modelo, os quais reduzem significativamente o consumo de recursos no processamento das consultas. Embora projetados para o escalonamento da multi-junção espacial, esses métodos podem também ser aplicados a outros tipos de problemas em sistemas distribuídos, que necessitam do alinhamento de partições de dados e da distribuição de tarefas a máquinas de forma balanceada. Além disso, propomos um método para controlar o uso de recursos e aumentar a vazão do sistema na presença de restrições nas capacidades da rede ou de processamento. O otimizador proposto foi capaz de selecionar bons planos de execução para todas as consultas em nossos experimentos, as quais usaram datasets públicos com uma variedade significativa de tamanhos e de objetos espaciais complexos. Apresentamos também uma máquina de execução, capaz de executar as consultas com escalabilidade próxima de linear em relação ao tempo de execução.

This thesis compares the selected type of property valuation methods in the garage area of the Prostějov. Due to instructions of the work, the methods of valuation were chosen: cost method, comparison according to law and comparison based on databases. The thesis consists of a theoretical part, where is the introduction of basic concepts, market analysis and valuation of real estate. This is followed by a practical part, where is the description of the site and the actual value of selected garages with their descriptions and photographs. Differences of ways of valuation and their causes, which are based on obtained data, are discussed at the end of work.

This thesis focuses on assessing the differences in prices of garages in various areas of the town of Olomouc. To state the differences two methods were used: the cost-based appraising method and the comparative method. In addition, market price were stated and compared to the administrative one. There were fifteen garages selected for the purpose of this text. In the first part of this work basic concepts are defined. The following part is descriptive and brings the town of Olomouc into focus. Further on, particular ways of appraising are explained. Next, the selected garages are introduced and appraised. In conclusion, based on given facts, the factors influencing prices of garages are assessed as well as the causes of discrepancies between prices stated with the use of different methods.

The demand of fast food is increasing in current food market worldwide. But fast food, as one of the unhealthy food types, cannot deny its impact as one of the causes of leading death in populations of most high income countries. Healthy fast food is called by governments, health organizations and societies, and desired by customers especially in Sweden because it is affordable, easy accessible, and most immortally, healthy. Companies are emerging based on the current fast food demand to provide healthy one in its unique style and format to meet the needs of healthy food in Sweden market. This research focuses on pricing approach and strategy that is suitable for products of healthy fast food based on literature research and interviews of fast food business owners in Stockholm. According to both literature information and interview results, value based pricing strategy was indicating as a better solution in health fast food business especially in start-up business. The application of value based pricing strategy requires discipline and practice with barrier overcome solutions, and factors with impact on pricing decision making need to be considered to ensure maximum profitability. Furthermore, healthy fast food is a new and promising business trend with developable future, and environmental friendly packaging fits to its business style and customer need.

Syfte: Syftet med studien är att genom en flerfallsstudie analysera och söka förståelse för sambanden mellan prissättningsstrategier och prissättningsmetoder som tillämpas hos företag som riktar sin verksamhet främst mot andra företag, B2B. Analysen av empirin sker med hjälp av redan existerande teorier om prisstrategier och prissättningsmetoder. Trots studiens fokus på ett visst företag inom en viss bransch är ändå förhoppningen att studiens slutsatser ska kunna vara av intresse för B2B-företag med samma kostnadsstrukturer. Metod: Ramen för studien utgörs av en deduktiv ansats med kvalitativ undersökningsdesign. Företagen i studien har studerats genom en flerfallsstudie med semistrukturerade intervjuer som metod för att insamla data. Teoretisk referensram: Uppsatsens teoretiska del innefattar teorier från företagsekonomisk forskning som förklarar vanliga prisstrategier, prissättningsmetoder och dess funktioner. Begreppen Price Waterfall och Strategic Fit har behandlats för att i analysen kunna se hur väl företagens övriga aktiviteter integrerar med prissättningsprocessen. Slutsats: Målet med denna studie är att besvara frågeställningen: Vilka samband finns det mellan prissättningsstrategier och prissättningsmetoder inom B2B-fötetag? Resultatet visar att det finns tydliga samband på flera områden. Det finns flera slutsatser att dra av denna studie, men den viktigaste slutsatsen är: För att vinstmaximera sina prisstrategier måste man hitta samband med flera olika prissättningsmetoder och arbeta med dessa på ett aktivt sätt i hela organisationen / Purpose: The purpose of this thesis is to analyze and seek knowledge about the connection between pricing strategy and pricing methods in B2B companies. The analysis was conducted with help from already exciting theory about pricing strategy and pricing methods. Even though the study is conducted on a small amount of companies in a special branch, the ambition is that this thesis could be of interest for B2B-companies with the same structures of cost. Method: The thesis uses a deductive and qualitative approach. The data is collected from a case study conducted through semi-structured interviews. Theoretical framework: The base of the theoretical approach is a number of theories from business and specialist literature that have explained common pricing strategy and pricing methods. The concept of Price Waterfall and Strategic Fit is used to analyze how the companies’ activities integrate with the pricing process. Conclusion: The purpose of this study is to answer the question: What is the relationship between pricing strategies and pricing practices in B2B companies? The result shows that there are clear links in several areas. There are several conclusions to draw from this study, but the main conclusion is that to maximize profits the pricing strategies must be associated with several different pricing methods and work with them in an active way in the whole organization

How to price your offering is one of the main managerial decision issues today and is alarmingly often not grounded in necessary market and cost research. Pricing is a complex topic, dependent on a multitude of internal and external factors, which makes pricing practice and strategy alignment even more difficult. As a simplifying measure, pricing practices are commonly categorized into three categories: cost-based, competition-based and value-based pricing, of which value-based pricing is considered the superior practice by scholars. Consequently, the issue of how to adopt value-based pricing and how to actually price according to value is pertinent and a main focus of this thesis. What comprises perceived customer value, how a firm creates and captures value, and how a firm chooses to formulate the customer value proposition in order to communicate the generated value are all questions that this thesis investigates and attempts to answer. Furthermore, the effects of the customer-supplier relationship on pricing and change management aspects of a transition to value-based pricing are also investigated and analyzed. In order to answer the research purpose and accompanying research questions, a qualitative single case-study was conducted. The case company was a leading company in the TIC-market, who just recently had started discussing implementing value-based pricing and was therefore deemed as an appropriate case for this study. Empirical data was gathered through semi-structured interviews with the employees as well as the customers of the case company. The analysis of the empirical data in conjunction with the theoretical framework led to a revised analytical model that attempts to explain the relations and correlations of the different concepts discussed in this thesis, as well as conclusions regarding the aforementioned research questions. This study concludes that the common value drivers are Quality, Delivery reliability, Delivery time, Price, Geographical location, Relationship and communication, Customization. Additionally, the study concludes that the alignment of pricing practice and strategy is heavily dependent on internal and external awareness, and it is of utmost importance for a firm engaging in value-based pricing to know not only their customer and market, but also their own capabilities and strengths. Regarding how to formulate the customer value proposition, the study concludes that it should be customized for the specific customer and have a resonating focus with elements of points of difference. Lastly, the study details the challenges that a firm transitioning to a value-based pricing practice might encounter, and the suggestive solutions to these obstacles.
