Esta dissertação aborda a análise custo-benefício (ACB) em manejo florestal sustentável (MFS) em Roraima, Unidade da Federação pertencente à Amazônia Legal que assim como os outros Estados sofrem com a falta de alternativas econômicas frente à pressão regional e internacional de não uso dos recursos da floresta. Por essa razão, este trabalho, procurou estudar a viabilidade da atividade de manejo florestal sustentável (MFS), a fim de subsidiar futuros empreendimentos que sejam ao mesmo tempo economicamente viável e ambientalmente corretos. Para alcançar tal objetivo foi necessário expor exaustivamente a corrente do desenvolvimento sustentável, tais como, sua origem, o contexto histórico, seus conceitos, tratados e convenções que asseguraram juridicamente o pensamento conservacionista. Além disso, foi preciso embasamento na Ciência Econômica, com o conteúdo transversal sobre a Curva de Kuznets, conceito de bens públicos e as implicâncias das externalidades no custo ambiental, bem como de contribuições de economistas como Pigou, Meadows e Tietenberg. Assim, também, indispensável foi inserir na discussão, dados, conceitos e o histórico da região em discussão qual seja, a Amazônia (especialmente a roraimense) bioma possuidor de apelo internacional haja vista sua indiscutível importância para o equilíbrio ambiental do Brasil e sua contribuição para todo o planeta terra. Por fim, conjugou-se a aplicação da ACB e suas ferramentas (como os método de valoração ambiental) com o manejo florestal sustentável (MFS) objetivando o alcance do desiderato inicial, qual seja, a viabilidade ou não de modelos de extração de madeira na Amazônia de Roraima. O resultado obtido foi de que, dos três modelos estudados apenas o modelo em manejo florestal sustentável (MFS) apresentou viabilidade econômica e ambiental, tendo em vista que nos dois primeiros modelos em sistema e produção convencional (um sem e outro com custo ambiental) não atenderam aos requisitos dos indicadores do estudo: valor presente líquido (VPL), taxa interna de retorno (TIR) e a razão B/C. Aliás, duas das análises que levaram em conta os custos dos impactos ambientais foram denominadas de análise custo-benefício ampliada ou ambiental (ACBA), que são variações ou alternativas ao modelo de ACB convencional ou simples. Desse modo, o benefício do modelo MFS supera seus custos o que torna atrativos para investidores privados e públicos, bem como para financiamento via fundos ambientais nacionais e internacionais ou via financiamento via Banco Mundial, Comunidade Européia, entre outros agentes de fomento. / This study approach the cost-benefit analysis (CBA) in sustainable forest management (SFM) in Roraima, Brazilian State owned by Amazon that just as other states suffer from a lack of economic alternatives facing the regional and international pressure not to use of forest resources. Therefore, this study sought to investigate the feasibility of the activity of sustainable forest management (SFM) in order to support future developments that are both economically viable and environmentally sound. To achieve this it was necessary to thoroughly expose the chain of sustainable development, such as its origin, historical context, its concepts, treaties and conventions which ensure legal thinking conservationist. Moreover, it was necessary grounding in economic science, with the content on the transverse Kuznets Curve, a concept of public goods and the implications of externalities in the environmental cost, as well as contributions from economists like Pigou, Meadows and Tietenberg. So, too, was essential to enter into the discussion, data, concepts and history of the region under discussion which is the Amazon (especially roraimense) biome possessed of international appeal has seen its unquestionable importance to the environmental balance of Brazil and its contribution to all the planet earth. Finally, conjugated to the implementation of the CBA and its tools (such as the valuation method) with sustainable forest management (SFM) in order to reach the first desideratum, namely, the feasibility or otherwise of models of logging on Amazon Roraima. The result was that the three models studied only the model in sustainable forest management (SFM) presented economic and environmental viability, given that the first two models and conventional production system (one without and one with environmental cost) is not met the requirements of the study indicators: net present value (NPV), internal rate of return (IRR) and the ratio B/C. Indeed, two of the analysis that took into account the costs of environmental impacts were identified as extended cost-benefit analysis or environmental (ACBA), which are a variation, or alternatives to the conventional model of CBA or simple. Thus, the benefit of the MFS model exceeds its cost which makes it attractive for private and public investors, as well as financing through national and international environmental funds or by funding through the World Bank, European Community, and other agents of promotion.

The aim of this thesis is to contribute to the risk methodology field by introducing a method that covers both economic and information security aspects. The aim is to provide a way for practitioners to get results that is enough for decision makers to make valid and well-grounded decisions. There are a lot of traditional risk assessment methods that focus on information security. There are also CBA (Cost-Benefit Analysis) methods that are used to make sure investments are cost-effective and provide value for the organization. The aim of this thesis is to combine those and see if they can be merged to one risk assessment method to increase the value of the result. CBA will be added to a more traditional risk assessment method called IRAM2. The thesis will evaluate if they are suited to be used together and if it provides a more valuable result when combining them than only using one of them. The research method that has been used in this study is ADR. It has been used as a way of working when producing a new hybrid method together with some design principles regarding how to combine traditional risk management with economic equations.

Städerna i Sverige växer och med det även de miljöproblem som urbaniserade områden medför. Sedumtak är en dagvattenhanteringslösning som medför ett flertal miljöfördelar, men det är fram till idag inte klargjort om anläggningen av sedumtak i Stockholmsområdet är samhällsekonomiskt försvarbart. Syftet med denna studie är därför att avgöra om anläggningen av sedumtak är samhällsekonomiskt lönsamt i Stockholmsområdet. En samhällsekonomisk konsekvensanalys har genomförts i Huddinge kommun där nettonuvärdet av ett sedumtak-projekt har sökts. Det finns lite värderingslitteratur gällande sedumtak och ett andra mål med uppsatsen har därför varit att undersöka om en trovärdig samhällsekonomisk konsekvensanalys kan genomföras i ett område där litteraturen är knapphändig.De identifierade nyttorna som sedumtak medför är minskad avrinning från tak, upptag av luftföroreningar och koldioxid, reduktion av buller, sänkt utomhustemperatur lokalt, ökat försäljningsvärde på bostäder samt förlängd livslängd på underliggande tak. Kostnaderna som uppstår är en ökad investeringskostnad, utsläpp av fosfor samt ökade underhållskostnader. Den största kostnaden är investeringskostnaden och den största nyttan är värdeökning av bostäder. Dessa nyttor och kostnader har så långt det är möjligt kvantifierats och värderats och beräkningar med nuvärdesmetoden visar på att anläggningen av sedumtak är samhällsekonomiskt lönsamt. Känslighetsanalysen visar på att resultatet är trovärdigt. Analysen har visat på att det är möjligt att genomföra en trovärdig samhällsekonomisk konsekvensanalys i ett område där litteraturen är knapphändig, förutsatt att målet är att avgöra om projektet är lönsamt eller inte och inte hur lönsamt det är. Det finns ett behov att utföra en liknande studie som denna, men som behandlar anläggningen av sedumtak i en större skala. Resultaten från detta examensarbete kan användas av beslutsfattare, planerare och andra tjänstemän inom samhällsbyggnadssektorn då det innefattar generell information om sedumtak samt en ekonomisk analys av investeringen. / The cities in Sweden are growing, and so too are the environmental problems that accompany development. Sedum roofs are stormwater management tools that come with many benefits, yet it is uncertain whether or not sedum roofs are in fact an advisable endeavor for society. This study aims to investigate whether sedum roofs in the Stockholm region are a profitable investment for society. A cost-benefit analysis (CBA) has been carried out in the municipality of Huddinge where the net present value of a sedum roof project is sought. The literature of green roof valuation is scarce, and a second aim is therefore to investigate if a reliable CBA can be conducted in an area where available data are limited. The identified benefits of sedum roofs are stormwater retention, air pollution and carbon dioxide removal, noise reduction, reduced outdoor temperature, increased sales value of apartments and increased life time of roof membrane. The costs that occur are an increased investment, spillage of phosphorus and increased maintenance costs. These costs and benefits have, as far as possible, been quantified and translated into monetary values. The greatest cost is that of investment, and the greatest benefit is the increased sales value of the apartments. Results from the CBA show that a sedum roof in the Stockholm region is a profitable investment for society. The sensitivity analysis indicates that these results are reliable. This study has shown that it is possible to conduct a reliable CBA in an area where the literature is scarce if the aim is to investigate whether a project is profitable for society or not, but not if the aim is to investigate how profitable a project is. A further study, in which a greater scale of sedum roof installation is considered, could be valuable. Decision makers, planners and operatives in city planning and the built environment can use the results from this master thesis in their work, as it provides general information about sedum roofs as well as an economic analysis of the investment.

High Speed Lines (HSL) in rail passenger services are regarded as one of the most significant projects in many countries comparing to other projects in the transportation area. According to the EU (European Council Directive 96/48/EC,2004) , high-speed lines are either new-built lines for speeds of 250km/h or greater, or in some cases upgraded traditional lines. At the beginning of 2008, there were 10,000 km of new HSL lines in operation, and by taking into account the upgraded conventional lines, in total, there were 20,000 km line in the world. The network is growing fast because of the demand for short travelling time and comfort isincreasing rapidly. Since HSL projects require a lot of capital, it is getting more important for governments and companies to estimate and to calculate the total costs and benefits of building, maintaining, and operating of HSL so that they can decide better and more reliable in choosing between projects. There are many parameters which affect the total costs and benefits of an HSL. The most important parameter is dimensional speed which has a great influence on other parameters. For example, tunnels need larger cross section for higher speed which increases construction costs. More important, higher speed also influences the number of passengers attracted from other modes of transport. Due to a large number of speed-dependant parameters, it is not a simple task to estimate an optimal dimensional speed by calculating the costs and benefits of an HSL manually. It is also difficult to do analysis for different speeds, as speed changes many other relevant parameters. As a matter of fact, there is a need for a computational model to calculate the cost-benefit for different speeds. Based on the computational model, it is possible to define different scenarios and compare them to each other to see what the potentially optimal speed would be for a new HSL project. Besides the optimal speed, it is also possible to analyze and find effects of two other important parameters, fare and frequency, by cost-benefit analysis (CBA). The probability model used in the calculation is based on an elasticity model, and input parameters are subject to flexibility to calibrate the model appropriately. Optimal high-speed line (OHSL) tool is developed to make the model accessible for the users.

Hydropower is a fundamental pillar in the Swedish energy system and accounts for a large part of the Swedish electricity production. The regulation power is also essential for balancing the grid load.  Fortum is one of the leading energy companies within hydropower and Klarälven is a river with high importance, where Fortum owns and operates nine powerplants. These power plants constitute a barrier for the wild salmonids in Klarälven, which need to migrate upstream to reach their spawning area. Since the 1930s, the spawning salmonids have been trapped and transported upstream by lorry. After the spawning period, the smolts and kelts, i.e. the juvenile and spawned salmonids, have to migrate downstream. Due to the lack of fishways, they are forced to pass the eight remaining power plants. This, together with predation, entails a high mortality rate. Two independently performed studies indicates on survival rates of 16 % and 30 %. To stabilize the wild salmonid population, the downstream survival must increase, and a proposed solution is to implement a downstream trap-and-transport solution. This trap implementation could be a step towards the environmental adaptation of hydropower and a part of the action plan proposed in June 2016, during the Agreement on Swedish energy policy. To find the most cost-beneficial environmental measure, a socio-economic assessment method can be used. A Cost-Benefit Analysis (CBA) is a commonly used socio-economic method, which evaluates the benefits and costs during the entire project lifetime. Energiforsk has, within the project FRAM-KLIV, developed a CBA tool that aims to simplify the socio-economic evaluation. The purpose of this thesis was to investigate whether the CBA tool can be used in future permit processes to prioritize between different project proposals to find the most beneficial environmental improvements. In order to evaluate the tool, it was to be applied on the trap-and-transport project in Edsforsen to evaluate the possibility of a socio-economic profitability. Also, the concepts and theory behind CBA was to be analysed and the suitability of translating environmental consequences into monetary values was to be evaluated. In the analysis of Edsforsen, 13 scenarios were developed. The first scenario served as a basis for the other scenarios, which were created as a sensitivity analysis. The result of the CBA showed a large socio-economic benefit and the most important parameter was identified as people’s willingness to pay for an increase of the wild salmonid stock in Klarälven. In the CBA, this parameter had a high uncertainty, as it was based on a survey performed for another project in another part of Sweden. It was found that in order for the socio-economic result to be positive, all households in Sweden must be willing to pay at least 35 SEK. As a complement to the CBA result, an evaluation regarding the marginal cost per fish was performed and an interval of 50-580 SEK per smolt was obtained. However, the calculations were based on several uncertainties and the interval should therefore be interpreted as a guideline rather than a precise result. It was concluded that in situations when a socio-economic analysis is required, and when it is possible to express consequences in monetary values, the method of CBA is appropriate. It is also a suitable methodology for evaluations of large projects, as it provides a comprehensible overview of the costs and the benefits. Despite the criticism directed towards CBA regarding uncertainties and its anthropogenic perspective, it could be concluded that using CBA as a socio-economic assessment method provides a perspicuous and quantitative result. Thus, the usage of CBA in prioritization processes of different environmental measures can be highly useful. Energiforsk’s CBA tool provides a framework with guidelines that can be highly useful and accelerate the analysis process. However, the performance of the tool version used in this thesis was not fully satisfactory due to a few malfunctions. The tool is still under development and it is likely that these errors will be adjusted in future versions. If the malfunctions in the tool would be adjusted, it could become useful for authorities, companies and other actors that wants to evaluate hydropower related environmental measures or when prioritizing between different project proposals to find the most beneficial environmental improvements in future permit processes.

In a 2023 where global crises follow one another, globallogistics have been heavily affected and have thereforebecome an increasingly important focus area. The issues thathave arisen have led companies and organizations to exploretheir options for insourcing processes that were previouslyoutsourced, in order to avoid unnecessary risks withdeliveries and their timelines.In this quantitative deductive case study, the purpose is toexamine the advantages and disadvantages of insourcingwithin the industrial sector. To investigate this purpose, fourmethods were used: flow diagrams, Value Stream Mapping(VSM), Cost-Benefit Analysis (CBA), and digitalization ofwhiteboards meant for meetings. The results showed severalimprovements, primarily through reduced lead times, positiveprofitability, and more efficient workflows.The conclusions of the study are that insourcing processescan bring several positive aspects to the organization, with themain barrier being investment costs / I ett 2023 där globala kriser avlöser varandra så har denglobala logistiken påverkats kraftigt och därav blivit ett alltstörre fokusområde. Problematiken som skapats har lett till attföretag och verksamheter har utforskat sina möjligheter attinsourca processer som tidigare har varit outsourcade för attundvika onödiga risker med leveranser och dess tider.I denna fallstudie så är studiens syfte att undersöka vilkamöjligheter och utmaningar som insourcing av enindustriprocess medför på verksamheten. För att besvaraforskningsfrågan så användes Value Stream Mapping (VSM)och Cost-Benefit-Analysis (CBA). Resultatet visade på ettflertal förbättringar, främst genom förkortade ledtider, enpositiv lönsamhet samt effektivare arbetssätt. Ledtidernaminskade med 88% för processen vilket motsvarade 16% avverksamhetens totala ledtid. Med en avkastning på 14,2% perår gör att investerings kapitalet är återbetalt efter 7 år i drift.

Denna uppsats utför en samhällsekonomisk analys av att investera i en utbyggnad till dubbelspår på den nästan 50 mil långa Malmbanan, med fokus på hur detta skulle påverka det svenska gruvbolaget LKAB:s verksamhet. Genom att använda kostnads-nyttoanalyser (CBA) och känslighetsanalyser, undersöks de ekonomiska fördelarna och kostnaderna av ett sådant projekt. Denna studie bidrar med en kompletterande synvinkel till Trafikverkets tidigare analyser genom att inkludera potentiella ökningar i exportintäkter och långsiktiga ekonomiska fördelar för den svenska ekonomin. I norra Sverige sker omfattande industriinvesteringar om ca 880 miljarder SEK och Malmbanan anses enligt flera aktörer spela en kritisk roll för den svenska ekonomiska utvecklingen. Undersökningen noterar den mängd aktörer som påverkas av investeringar i Malmbanan men väljer att enbart fokusera på LKAB:s påverkan av ett eventuellt dubbelspår. Analysen visar att en utbyggnad till dubbelspår ger betydande ekonomiska vinster för LKAB, vilket motiverar projektet trots de höga initiala investeringskostnaderna om 120 miljarder SEK. Huvudkalkylen visar på en nettolönsamhet på +213 miljarder för LKAB under 20 år med diskonteringsräntan 3.5% och +172 miljarder med diskonteringsräntan 6%. Projektet bidrar med flera positiva effekter som ej kvantifierats, som bland annat färre förseningar och urspårningar, utveckling i enlighet med de transportpolitiska målen och positiv påverkan för andra aktörer. Känslighetsanalyser som tar hänsyn till lägre export med förhöjda investeringskostnader visar på en netto lönsamhet på -93 miljarder SEK med positiva, ej kvantifierade, effekter.  Arbetet konkluderar att investeringen med stor sannolikhet bör genomföras men att vidare forskning behövs då denna studie inte kan garantera att en utbyggnad till dubbelspår är den bästa allokeringen av resurser.
