Responsabilidade social corporativa: benefício social ou vantagem competitiva?: um estudo das estratégias de atuação social empresarial e sua avaliação de resultados / Corporate social responsability: social benefit and competitive advantageMaria Cristina Lopes Fedato 12 December 2005 (has links)
Esta dissertação tem por objetivo estudar os principais conceitos que definem a responsabilidade social corporativa e refletir sobre o papel das empresas na sociedade onde estão inseridas. A partir da definição da atuação social como parte de uma estratégia de responsabilidade social nas empresas, foram pesquisadas algumas características destas ações sociais, identificando as formas como são avaliados seus resultados e verificando se é possível desenvolver ações que ao mesmo tempo produzam benefícios sociais e vantagens competitivas para as empresas. O referencial teórico trata do tema da responsabilidade social corporativa, apresenta um panorama da atuação social empresarial no Brasil, analisa as formas e abordagens da avaliação de resultados de ações sociais e discute as tendências atuais de criação de empreendimentos que buscam a geração combinada de valor econômico e social. O trabalho de campo foi desenvolvido em duas etapas, sendo uma de caráter qualitativo, composta por dois estudos de caso e a outra de caráter quantitativo, realizada na forma de uma survey. Na primeira etapa foram estudados dois casos de empresas que desenvolvem negócios com comunidades de baixa renda na Amazônia, Região Norte do Brasil. Um dos casos se refere a uma empresa fabricante de cosméticos, que desenvolve sua principal linha de produtos utilizando, como principais insumos, ativos da biodiversidade brasileira e conta com cooperativas locais como seus principais fornecedores. O outro caso trata de uma empresa fabricante de papel e celulose que se associa a comunidades nativas e se torna membro de uma cooperativa para organizar a produção de uma de suas principais matérias-primas. A partir destas iniciativas empreendedoras e visionárias é possível demonstrar que a despeito dos riscos e das dificuldades inerentes ao pioneirismo, a conciliação de benefício social e vantagem competitiva é factível e viável. Na segunda etapa foi realizada uma survey junto a uma amostra intencional de 60 empresas, traçando um perfil se seu investimento social, de sua estratégia de atuação social, das práticas utilizadas de avaliação de resultados e das interfaces das ações sociais com o negócio. Entre os principais resultados obtidos pode-se destacar que empresas de porte pequeno e médio investem em ações sociais tanto quanto empresas de grande porte, e que empresas de capital aberto tendem a tratar a estratégia de atuação social com maior grau de formalização e planejamento que as empresas de capital fechado. A maioria das empresas investe em projetos sociais nas mesmas regiões onde desenvolve seus negócios e os principais públicos atendidos pelas ações sociais são crianças e adolescentes, através de ações predominantemente voltadas à educação. Entre as empresas com estratégia de atuação social mais madura foram detectados diversos pontos de interface e sinergia das ações com o negócio, demonstrando que a responsabilidade social é uma dimensão indissociável dos negócios. Espera-se com este trabalho explicitar o caráter estratégico da responsabilidade social corporativa e amadurecer a reflexão sobre as possibilidades de se planejar empreendimentos sustentáveis e competitivos que combinem geração de valor econômico e social. / The scope of this dissertation resides in analyzing the main concepts that define corporate social responsibility as well as reflecting on the role of enterprises in the community. Based on the definition of social action as part of a strategy of corporate social responsibility, some characteristics of these social actions have been researched, identifying the means through which their results are evaluated and verifying the feasibility of developing actions that will simultaneously produce social benefit and competitive advantage for the enterprises. The theoretical reference encompasses the theme of corporate social responsibility, presents an overview of social action on the part of Brazilian enterprises, analyzes the ways and approaches of social action result evaluation and discusses the current trends of creating entrepreneurships that seek at a combined generation of social and economic value. The field work has been developed in two stages, being one of qualitative characteristics, formed by two case studies, and another of quantitative feature, accomplished as a survey. During the first phase, two cases were prepared, approaching enterprises that do business with low-income communities in the Amazon, in the North of Brazil. One of them refers to a cosmetics manufacturer that enroots its core product line having assets from the Brazilian biodiversity as main inputs. Besides, it counts on local cooperatives as its leading suppliers. The other case overlooks a pulp and paper manufacturer that associates to native communities and becomes member of a cooperative in order to organize the production of one of its main raw materials. From these entrepreneurial and visionary initiatives, it is possible to demonstrate that in spite of the risks and difficulties inherent to pioneering, the conciliation of social benefit and competitive advantage is feasible and doable. During the second phase, a survey was accomplished considering a sample of 60 enterprises, sketching a profile of their social investment, their social action strategy, the practices adopted for evaluating results and the interfaces between social action and business. Among the main results obtained, one may highlight that small and medium-sized enterprises do invest in social action as much as the large ones; and that limited liability corporations tend to treat the social action strategy in a more formal and planned fashion than limited liability partnerships. Most enterprises invest in social projects located close to where they do business and the populations most commonly served by their social actions are formed by children and adolescents, through projects that prioritize education. Among the companies with more mature social action strategy, several points of interface and synergy have been detected between social action and business, emphasizing their amalgamation. With this here production, one expects to demonstrate the strategic feature of corporate social responsibility and to evolve in the reflection on the possibilities of planning sustainable and competitive entrepreneurships that overlap social and economic value generation.

Previous issue date: 2006 / Resumo: Como se dá a percepção da realidade virtual pelas pessoas e como utilizá-la para fazer uma avaliação de um ambiente em fase de projeto? Esta é a questão que norteou a realização desta pesquisa. Um trabalho anterior verificou que questões subjetivas (com escala de valores de eficiência como respostas) são pouco eficientes para avaliar a percepção do usuário em um ambiente simulado por meio de realidade virtual passiva quando comparadas a questões objetivas (com respostas específicas do tipo sim, não ou lista de checagem). Entretanto são respostas às questões com escalas de valores que mais dão retorno ao projetista sobre a opinião do usuário em relação ao projeto. Acreditava-se que a manutenção da percepção entre ambiente simulado e protótipo medida por questões subjetivas seria melhorada se associada à experimentação livre de um ambiente simulado por realidade virtual exploratória, situação esta não possível com realidade virtual passiva. De acordo com este raciocínio foi realizado um experimento durante o evento UNICAMP de Portas Abertas (UPA) em 2005 para avaliar se a realidade virtual exploratória implementada pelos softwares QuicktimeVr e Quest3d auxiliariam o usuário e o projetista na compreensão do projeto arquitetônico e se haveria alguma diferença na manutenção de percepção entre os ambientes virtuais proporcionados por cada um destes aplicativos. O experimento comparou a percepção dos participantes do UPA 2005 entre ambiente simulado e protótipo. O ambiente estudado foi composto por mesa de estudo/trabalho, espaço para cadeira e armário. As questões utilizadas para avaliar a percepção relacionavam-se ao espaço/conforto para abrir a porta do armário e espaço/conforto para circular entre mesa e armário. O participante experimentava primeiramente o espaço simulado e respondia as questões e em seguida experimentava o protótipo respondendo mais uma vez as mesmas questões. A manutenção de percepção é calculada comparando as respostas entre questões idênticas sobre o ambiente simulado e o protótipo. Concluiu-se que a não imersão ou imersão mínima (ou menos interação e maior interação) oferecida nas implementações de realidade virtual com QuicktimeVr e Quest3d respectivamente, para a amostra analisada, influenciam de forma diversa e sem padrão na manutenção de percepção do usuário. Observou-se, diferentemente do esperado, com realidade virtual exploratória uma manutenção de percepção menor do que aquela apresentada por pesquisa desenvolvida com realidade virtual passiva. Verificou-se que os filtros de percepção influenciam de forma diversa na manutenção de percepção dependendo da questão sendo avaliada e do recurso de RV. Outra constatação é sobre a influência da escala de valores adotada para questões subjetivas no cálculo da manutenção de percepção, indicado extremo cuidado no desenvolvimento de um questionário para tal propósito / Abstract: How do people perceive space simulated by virtual reality and can such resource can be used in the architectural design evaluation process? This is the question which guided this research. An earlier work verified that subjective questions (with a scale of values of efficiency) are less efficient to evaluate the user's perception in a simulated environment with passive virtual reality (VR) when compared with objective questions (with specific answers as yes or no or with checklists). Meanwhile questions with answers in scale of values give more return to designers about the users opinion of a project. Therefore, in order to improve performance of perception maintenance between the simulated environment and the prototype measured by subjective questions we believed that free experimentation of a simulated environment in exploratory VR would be better than passive VR. In agreement with this induction it was realized an experiment during the event UNICAMP de PortasAbertas (UPA) in 2005 to evaluate if exploratory virtual reality implemented by software Quicktime VR and Quest3d should help the user and the designer in understanding the architectural project and if there should be any difference in perception maintenance between these to kind of VR implementation. The experiment compared the participator's perception in the UPA 2005 between virtual environment and prototype. The studied environment was composed by a study/work table, space for chair and partially closed book shelve. The questions used to evaluate the perception were related with space/comfort to open the book shelve door and space/comfort to circulate between the table and the book shelve. The participant first experimented the simulated space and then answered to the questionnaire, after that he/she experimented the prototype answering the same questions. The perception maintenance was calculated between the answer comparison of identical questions about the simulated environment and the prototype. It was concluded that the non immersion or the minimal immersion (or less interaction and more interaction) offered in the VR implementations with Quicktime VR and Quest3d respectively influenced divisively and without pattern the perception maintenance in the studied sample. It was observed, on the contrary of the expected a smaller perception maintenance with exploratory VR than that presented by previous research using passive VR. It was verified that the filter perceptions such as age, sex, study level, familiarity with computer 3D animation and with the studied environment influence differently depending on the question used in the questionnaire and on the VR implementation. Another conclusion is about the scale of values adopted for subjective question in the perception maintenance calculation, they were not capable to confirm participant opinion and indicate extreme care in the development of a questionnare for this purpose / Mestrado / Edificações / Mestre em Engenharia Civil

[en] PROJECT SELECTION PROCESS IN A POWER UTILITY FIRM IN BRAZIL USING MULTI-CRITERIA ANALYSIS / [pt] CLASSIFICAÇÃO DE PROJETOS EM DISTRIBUIDORAS DE ENERGIA ELÉTRICA NO BRASIL UTILIZANDO ANALISE DE DECISÃO MULTICRITÉRIOFABIO JORGE SIERVO DA MOTTA 16 August 2011 (has links)
[pt] A avaliação de projetos e sua viabilidade econômico-financeira tradicionalmente são calculadas utilizando o método consagrado do fluxo de caixa descontado. Entretanto, o fato de um projeto ser financeiramente viável não significa necessariamente que ele reflita a preferência dos stakeholders. Além disso, a metodologia do fluxo de caixa descontado não consegue avaliar de forma eficiente projetos que possuem aspectos qualitativos relevantes. Por isso, é necessária uma metodologia que seja capaz de captar esses aspectos, como a Análise Multicritério (AMC). Dessa forma, o trabalho tem como objetivo mostrar o processo de escolha e priorização de projetos por um Comitê de Investimentos hipotético em uma distribuidora de energia elétrica através da utilização de um método de analise multicritério, o MAPM (Mutiattribute Preference Model), e como esses aspectos quantitativos e qualitativos podem ser relevantes para tomada de decisão. Foram atribuídos pesos a objetivos (dois) e critérios (sete), para a geração da função utilidade de cada um dos tomadores de decisão e analisou-se o comportamento e a coerência das decisões produzidas pelo calculo dos scores de cada projeto, os quais apresentaram consistência. Adicionalmente, foi realizada comparação dos resultados obtidos com aqueles gerados através da utilização de outro método de analise multicritério, o AHP (Analytic Hierarchy Process), e observou-se similaridade nos mesmos. Esses resultados, especialmente quando aplicados num contexto real de decisão numa distribuidora de energia elétrica, demonstra que a análise multicritério pode ser uma ferramenta relevante de avaliação e priorização de projetos. / [en] The evaluation of a project and its economic and financial viability are frequently calculated using the discounted cash flow method. However, the fact that a project is financially feasible doesn´t necessarily means that it reflects the preferences of the stakeholders. Besides this, the discounted cash flow method isn´t capable of valuing projects with relevant qualitative aspects. In order to try to capture these significant aspects, an appraisal methodology such as Multi-criteria analysis (MCA) is required. This article describes a project selection process made by an Investment Committee (IC)in a power utility firm using a multi-criteria analysis method, the MAPM (Mutiattribute Preference Model), and how these quantitative and qualitative criteria can play a relevant role for the project selection decision. We study the decision process by first asking the IC members to attribute weights for both objectives (two) and criteria (seven), in order to access the utility function of each IC member and then analyzing the behavior and consistency of the decisions produced through calculation of the score of each project. Results indicate that there is consistency between the strategy defined by the firm and the project selection process. Additionally, the results obtained with the MAPM approach were compared with these obtained using another MCA methodology: the AHP (Analytic Hierarchy Process), which yields similar results. The results also show that the application of multi-criteria analysis in a real context of a power utility firm can play a relevant role on capital investment valuation and decision tacking process.

Evaluating the Strategic Benefits of the ITS Implementation at the Värta Port / Bedömning av de strategiska fördelarna med ITS systemet I VärtahamnenAndersson, Eric January 2018 (has links)
When City of Stockholm wanted to build apartments on land used and controlled by Ports of Stockholm a project was initiated with the purpose of accommodating this request. The project meant that one of the piers at the Värta Port was expanded and the ITS system was implemented at said pier. Since the project was initiated from, what was considered, necessity an extensive evaluation of the economic and strategic consequences was not preformed. This thesis discusses and evaluates the strategical aspects of the ITS implementation at the Värta Port. The strategical benefits of the ITS system is that it enhances the competitive advantage, the location, of Ports of Stockholm through giving them more control over the port since the infrastructure was previously owned by their customer, Tallink Silja. Furthermore, the system creates a safer work environment at the port through better controlled container and truck management and preplanned emergency scenarios. The system also removes wastes in the logistical process in the port through the added control of entries and exits and a fully digital sorting and storing system. This can provide operational cost reductions to Tallink Silja who is responsible for the operation of the port. Additionally, the system provides added value for the end customer as the reliability of the shipments increase. If these benefits are enough to justify the ITS system cannot be determined in this thesis as it is only the management at Ports of Stockholm that possesses the implicit knowledge required, but there exist substantial strategical benefits to the ITS system. / När Stockholms Stad ville bygga lägenheter på mark som användes och ägdes av Stockholms Hamnar initierades ett projekt med avsikt att förfylla denna begäran. Projektet betydde en utbyggnad av ena kajen I Värtahamnen och ITS systemets implementation vid sagd kaj. Då projektet var initierat, av, vad som ansågs vara, nödvändighet utfördes ej en ordentlig bedömning av de strategiska och ekonomiska konsekvenserna. Denna uppsats diskuterar och bedömer de strategiska aspekterna av ITS systemet. De strategiska fördelarna av ITS systemet är att det bidrar till Stockholms Hamnars Konkurrensfördel, dess placering, genom att ge dem mer kontroll över hamnen eftersom infrastrukturen tidigare ägdes av deras kund, Tallink Silja. Utöver detta skapar systemet en säkrare arbetsmiljö i hamnen då systemet har bättre kontroll över containrarna och lastbilarna i hamnen samt har inprogrammerade utrymnings scenarier. ITS systemet minskar även på ”waste” i det logistiska processerna i hamnen genom adderad kontroll över in och utfarterna till hamnen samt ett digitalt sorterings och förvarningssystem. Detta erbjuder reduktioner i operativa kostnader för Tallink Silja, vilka är ansvariga för driften av kajen. Utöver detta erbjuder systemet ökat värde för slutkunden då verksamhetens reliabilitet ökar. Om dessa fördelar är tillräckliga för att justifiera ITS projectet kan inte beslutas i denna rapport då det endast är ledningen hos Stockholms Hamnar som sitter på kunskaper tillräckliga för att ta detta beslut. Men det finns bra strategiska fördelar med ITS systemet.

Probabilistic Risk Analysis in Transport Project Economic EvaluationLieswyn, John January 2012 (has links)
Transport infrastructure investment decision making is typically based on a range of inputs such as social, environmental and economic factors. The benefit cost ratio (BCR), a measure of economic efficiency (“value for money”) determined through cost benefit analysis (CBA), is dependent on accurate estimates of the various option costs and net social benefits such as reductions in travel time, accidents, and vehicle operating costs. However, most evaluations are deterministic procedures using point estimates for the inputs and producing point estimates for the outputs. Transport planners have primarily focused on the cost risks and treat risk through sensitivity testing. Probabilistic risk analysis techniques are available which could provide more information about the statistical confidence of the economic evaluation outputs.
This research project report investigated how risk and uncertainty are dealt with in the literature and guidelines. The treatment of uncertainty in the Nelson Arterial Traffic Study (ATS) was reviewed and an opportunity to apply risk analysis to develop probabilities of sea level rise impacting on the coastal road options was identified.
A simplified transport model and economic evaluation case study based on the ATS was developed in Excel to enable the application of @RISK Monte Carlo simulation software. The simplifications mean that the results are not comparable with the ATS.
Seven input variables and their likely distributions were defined for simulation based on the literature review. The simulation of seven variables, five worksheets, and 10,000 iterations takes about 30 seconds of computation time. The input variables in rank order of influence on the BCR were capital cost, car mode share, unit vehicle operating cost, basic employment forecast growth rate, and unit value of time cost. The deterministically derived BCR of 0.75 is associated with a 50% chance that the BCR will be less than 0.6, although this probability is partly based on some statistical parameters without an empirical basis. In practice, probability distribution fitting to appropriate datasets should be undertaken to better support probabilistic risk analysis conclusions. Probabilities for different confidence levels can be reported to suit the risk tolerance of the decision makers.
It was determined that the risk analysis approach is feasible and can produce useful outputs, given a clear understanding of the data inputs and their associated distributions.

Environmental Determinants and Choice of Project Evaluation Techniques in US and UK FirmsSmolarski, Jan M. (Jan Mietek) 05 1900 (has links)
The purpose of this dissertation is to develop a theory that helps explain the conditions under which firms select certain project evaluation techniques. This study uses contingency theory to analyze the impact of environmental uncertainty on the choice of project evaluation techniques. In addition to a direct measure of uncertainty, several dimensions of uncertainty are included in this study. These dimensions of uncertainty include control structure, method of financing, foreign assets, method of growth, and product domination. This study also analyzes the use of project evaluation, management science and risk management techniques in US firms over time and in UK firms over time in order to compare to prior research. A comparison of firms in the two countries are also provided.
The primary method of data collection was a survey instrument. Data were also collected from annual reports and various other public sources.
The variables that appear significant in the choice of project evaluation technique in US firms are environmental uncertainty, control structure, method of financing, foreign assets, and product domination. The variable that appear significant in the choice of project evaluation technique in UK firms is method of financing. US firms favor discounted cash flow techniques although this study detected a slight decrease over time. UK firms continue to use non-discounted cash flow techniques, although the use of discounted cash flow techniques is widespread. There are significant differences between US and UK firms. US firms tend to use discounted cash flow techniques to a greater extent than UK firms.
This research makes a significant contribution in attempting to develop a theory explaining the use of project evaluation techniques in firms in the US and UK. In addition, several other developments relating to project evaluation, management science and risk management are discussed. The results of this study can be used by managers in refining and improving their existing project evaluation processes.

[pt] A recente entrada em vigor do Protocolo de Quioto e as
pesadas multas
impostas às empresas européias que não conseguirem reduzir
as suas emissões de
CO2, fazem do mercado de carbono uma realidade na América
Latina. O Brasil se
destaca como um dos países de maior potencial para
exportar créditos de carbono
no mundo, em grande parte, devido ao seu potencial para
produzir energia elétrica
a partir de fontes renováveis. Entretanto, a real
atratividade desse negócio ainda é
desconhecida no âmbito do setor elétrico brasileiro, tanto
pela dificuldade
encontrada para se estimar a sua produção efetiva de
créditos de carbono, quanto
pelo não reconhecimento das flexibilidades gerenciais
embutidas neste mercado.
Neste contexto, o objetivo principal deste trabalho é
desenvolver um arcabouço
metodológico capaz de determinar o valor incremental do
mercado de carbono nos
projetos de geração de energia elétrica em sistemas
hidrotérmicos interligados, tal
como o sistema brasileiro. Para tanto as metodologias
ACM0002 [1] e AMS-I.D
[2], ambas aprovadas pelo Comitê Executivo do Protocolo de
Quioto, serão
empregadas no cálculo da linha de base desses projetos.
Além disso, uma vez que
o preço do crédito de carbono pode ser considerado uma
variável aleatória, a
Teoria das Opções Reais será utilizada para avaliar as
flexibilidades gerenciais
embutidas no negócio. A opção considerada é avaliada pelos
métodos Binomial,
dos Mínimos Quadrados, e de Grant, Vora & Weeks. Os
processos estocásticos
Geométrico Browniano e de Difusão com Saltos são
utilizados para modelar o
preço do crédito de carbono. / [en] The recent ratification of the Kyoto Protocol and the
heavy penalties
imposed on the European firms not reducing their
Greenhouse Gas emissions,
make the Carbon Market a real asset for Latin America. In
this context, Brazil
appears as one of the biggest producers of Certified
Emissions Reductions, mostly
because of its potential to generate electricity power
from renewable sources.
Unfortunately, the real attractivity of this business is
still unknown in the
Brazilian Electric Sector, mainly because of the
difficulties in estimating the
future production level of the emission reductions and
because of the existence of
some managerial flexibilities that usually are note
recognized in this market. In
this context, the main objective of this work is to
develop a methodology to
evaluate the incremental payoff of the carbon market on
electricity generation
projects of interconnected hydrothermal systems, such as
the Brazilian System.
The methodologies ACM0002 [1] and AMS-I.D [2], both
approved by the Kyoto
Protocol Executive Board, will be used to determine the
baseline of these projects.
Besides that, considering that the carbon price is a
random variable, the Real
Option Approach will be used to evaluate the embedded
managerial flexibilities
on this business. The considered real option may be
evaluate by using the
binomial tree, least square Monte Carlo and the Grant,
Vora & Weeks methods.
Both the Geometric Brownian Motion and the Jump Diffusion
processes will be
used to model the price of the emission reductions.

[pt] Ao tomar suas decisões, o gerente se vê frente a frente
com
diferentes tipos de incertezas, entre elas, o tempo para
se
concluir um projeto. As características de inovação e
ineditismo dos projetos de Pesquisa e Desenvolvimento
aplicados à tecnologia reforçam ainda mais os cuidados a
serem tomados com a dimensão tempo no momento da decisão,
pois a penalidade pode ser até mesmo a perda de
uma oportunidade valiosa de negócio. Para quantificar o
impacto do esforço aplicado em um Projeto de Pesquisa e
Desenvolvimento Tecnológico no valor de um
empreendimento,
conduzido em um contexto onde o tempo é representado por
uma variável aleatória, desenvolvemos o modelo que
apresentamos neste trabalho. Para tanto utilizamos a
Teoria
das Opções Reais, considerando que o projeto se
desenvolve seqüencialmente e que pode ser abandonado em
qualquer estágio de desenvolvimento. O modelo utiliza uma
treliça para captar a incerteza técnica própria do
desenvolvimento do desempenho da tecnologia e considera
como
variável aleatória o tempo de conclusão de cada uma das
fases do projeto. O valor esperado do projeto, com a
flexibilidade propiciada pela opção de abandono
embutida no projeto de Pesquisa e Desenvolvimento, é
calculado combinando a Simulação de Monte Carlo e a
técnica
da Programação Dinâmica. Aplicamos o modelo para tratar o
caso de uma planta Gas-to-liquid (GTL). A função payoff do
projeto de Pesquisa e Desenvolvimento foi construída a
partir de diversas contribuições geradas no bojo de um
convênio firmado entre o Departamento de Engenharia
Industrial da PUC-RJ e a Petrobras S.A., com o objetivo
de
avaliar economicamente uma planta GTL. / [en] When making decisions, the figure of the manager comes
across different
types of uncertainties. Among them, the time to conclude a
project. The
characteristics of innovation and novelty in Research and
Development Projects
applied to technology, further reinforces the caution to be
taken regarding the
time dimension at the moment of the decision, since the
penalty could culminate
in the loss of a valuable business opportunity. In order to
quantify the impact of
the effort applied in a Research and Technological
Development Project, in the
value of an entrepreneurship conducted according to a
context in which time is
represented by a random variable, this study presents a
pertinent model.
Considering that a project sequentially evolves and can be
abandoned during any
stage of its development, the Theory of Real Options was
the chosen theoretical
framework. The model utilizes a lattice to capture the
technical uncertainty,
characteristics of the development of technology
performance, and takes in
account as a random variable the time of the conclusion of
each stage of the
project. The expected value of the project with the
flexibility provided by the
option to abandonment built in the Research and Development
Project, is
calculated through a combination of the Monte Carlo
Simulation and the
technique of Dynamic Programming. The proposed model was
applied in the case
of a Gas-to-liquid (GTL) plant. The payoff function of the
Research and
Development Project was built through several contributions
stemmed from an
agreement between the Industrial Engineering Department of
PUC-RJ and
Petrobras S.A., in order to assess the economic value of a
GTL plant
