Ett företag som ska välja mellan olika investeringsalternativ kan använda sig av nettonuvärdesmetoden för att beräkna vilken investering som anses mest lönsam. För att genomföra uträkningen prognostiseras framtida positiva kassaflöden som investeringen förväntas generera. Nettonuvärdesmetoden kan även användas vid bedömningar av infrastrukturinvesteringar men för den offentliga sektorn är de positiva kassaflödena inte lika frekventa i investeringsprocessen. För den offentliga sektorn är det istället befolkningens nytta av en investering som värderas. Nyttan är från början kvalitativ och värderas monetärt med hjälp av kalkylvärden, kalkylprinciper, trafikprognoser och andra verktyg. En monetär värdering av nytta gör att en nettonuvärdesuträkning blir möjlig. För att genomföra omformuleringen används en metod som kallas Cost-Benefit Analysis. Genom metoden identifieras de kvalitativa effekterna av en investering för att de sedan ska kunna kvantifieras. Studiens undersökningsenhet är Trafikverket som utvecklar och underhåller det Svenska transportsystemet. Studien har identifierat vilka värden Trafikverket kvantifierar i sin nettonuvärdesuträkning, vilka faktorer som ligger bakom värderingen och hur kvantifieringen går till. Det är nyttan i form av sparad tid, trafiksäkerhet och konsekvenser för miljö som kvantifieras. Undersökningen har skett genom insamling av teori i form av vetenskapliga artiklar samt rapporter och den empiriska utgångspunkten har varit de rekommendationer och den beräkningsmetodik som Trafikverket använder sig av vid den monetära värderingen. Värderingen av nytta som genereras av en investering är beroende av befolkningens betalningsvilja för ökad nytta. Det är den betalningsviljan som är grunden för de rekommendationer som Trafikverket följer. Resultatet har visat de faktorer som är grunden för värderingen, vilka värden som kvantifieras och hur kvantifieringen är möjlig, för att Trafikverket ska kunna använda nettonuvärdesmetoden för att göra en bedömning angående ett investeringsalternativ. / When a company decides which project to invest in among different alternatives they can use the net present value method. The method uses the expected generation of cash flow from the different investments in order to determine which investment would generate the most profit for the company. The net present value method can also be used by the public sector to decide between different projects. The public sector does not consider the same aspects with regards to cash flows as companies. The public sector calculates future cash flows in terms of benefits and costs for the countries population. The benefits from an investment are qualitative from the start and need to be monetized in order to be used in the net present value calculation. The quantification of the qualitative effects is accomplished though calculation values, calculation principles, traffic forecasts and other applications. To be able to facilitate the transformation the public sector can use a method called Cost-Benefit Analysis. The method makes it possible to identify the qualitative effects of an investment and then translate the effects to quantity values. A case study has been made with the Swedish Transport Administration as investigation unit, which is the organization that develops and maintains the Swedish transportation system. The case study has resulted in an identification of which values the Swedish Transport Administration decides to monetize, which aspects the values depends on and how the monetization is made. It is the benefits of saved travel time, value of a statistical life and environmental effects that are monetized. The theoretical part of the study is composed of scientific journals and reports. The empirical part of the study has been founded in the different recommendations and calculation methods which the Swedish Transport Administration uses to perform the monetization. The valuation of the benefits generated from a project is dependent on the populations’ willingness to pay for it. It is the willingness to pay which is the foundation of the recommendations which the Swedish Transport Administration adhere to. The results have shown the different aspects which are the foundation for the valuation. The results have also shown which values are quantified and how the quantification is possible to enable the Swedish Transport Administration to use the net present value method in order to judge different investment alternatives.

These initiatives have in common a high degree of community building, creating and sharing of content by the user, among other features. It is believed that social networks represent a high innovative and disruptive potential for the society and the business world. However, how to turn social networks and Web 2.0 applications in self-sustaining businesses models remains a challenge for the market. This dissertation intends to support the understanding and approach of the theme by proposing a specific ontology for business models of social networks on the Internet. This is accomplished through the development of a theoretical essay with an exploratory bias, based on extensive but not exhaustive literature review covering business models, social networks and other related topics. The created ontology is then applied in the representation of business models of social networks on the Internet. This work also provides an overview of the Web 2.0 phenomenon, covering some of its main technological and socioeconomic characteristics / Atualmente, uma profusão de soluções chamadas de Web 2.0 e redes sociais está causando um grande impacto no desenvolvimento da Internet, comparando-se à era 'ponto-com' em termos de crescimento, investimentos e empolgação. Estas iniciativas possuem em comum um elevado grau de formação de comunidades, e de criação e compartilhamento de conteúdo por parte do usuário, dentre outras características. Acredita-se que as redes sociais possuam um grande potencial inovador e disruptivo tanto para a sociedade quanto para o mundo empresarial. Entretanto, como transformar as redes sociais e aplicações Web 2.0 em modelos de negócios auto-sustentáveis ainda é um desafio para o mercado. Esta dissertação objetiva auxiliar a compreensão e abordagem deste tema propondo uma ontologia específica para modelos de negócios de redes sociais na internet. Isto se realiza por meio do desenvolvimento de um ensaio teórico de viés exploratório, baseado em extensa, porém não exaustiva, revisão de literatura abordando modelos de negócios, redes sociais e demais temas relacionados. A ontologia criada é então aplicada na representação de modelos de negócio de redes sociais na internet. Este trabalho também fornece uma visão geral do fenômeno Web 2.0, abordando algumas de suas principais características tecnológicas e socioeconômicas.
