A Methodology For Determining The Cluster Of A New Project

Yigit, Aybeniz 01 June 2005 (has links) (PDF)
By definition, all projects are unique / however R&amp / D projects have specific characteristics that make them harder to manage. The project management methodology applied to R&amp / D projects may show differences due to the categorization of them. But if there exists a categorization of projects, one can analyze the properties of the project classes and then manage similar projects similarly. In this study, the R&amp / D projects of a main military electronics company of Turkey, are analyzed. Tun&ccedil / (2004) has developed a methodology for clustering the projects of this electronics company. Continuing from his studies, a methodology for determining the class of a new project of this electronics company is developed. For defining the projects in a project space, a Project Identification Card (PIC) is developed. The measurement scale of the PIC is constructed by using the absolutemeasurement Analytic Hierarchy Process. A clustering Tabu Search algorithm is generated for using in the sensitivity analyses of the clusters to projects. And a methodology for determining the cluster of a new project is developed.

Understanding the Clean Development Mechanism and its dual aims : the case of China's projects

Sun, Qie January 2011 (has links)
Having been running for over 10 years, the Clean Development Mechanism (CDM) is considered an innovative and successful mitigation initiative. CDM has the dual aims of helping industrialised countries achieve compliance with their emission limitation and reduction commitments in a cost-effective way, while simultaneously assisting developing countries in sustainable development. This thesis does a comprehensive analysis of the dual aims of CDM and is intended to assist in discussions about the post-2012 regime regarding CDM. To analyse the aim of assisting mitigation in a cost-effective way, the prices of certified emission reductions (CERs) on the international carbon market was studied and the provision of CDM was tested by comparing the amount of CERs with the mitigation commitments of the Annex I countries. It was found that CDM plays an important role in maintaining the international carbon price at a low level and that the total amount of CERs alone had already reached up to 52.70% of the entire mitigation commitments of industrialized countries by the end of 2010 and was continuing to grow before 2012. A theoretical analysis of the impacts of CDM showed that CDM has a double mitigation effect in both developing countries and industrialised countries, without double counting at present. A quantitative evaluation of the effects of China’s CDM projects on China’s total emissions showed that the contribution of CDM projects to limiting total emissions is small due to the dominance of fossil fuels, but CDM’s role in stimulating renewable energy is significant, e.g. about 11% of hydropower and 93% of wind power was generated by CDM projects in 2010. The results provide strong evidence in support of CDM’s contribution under the current Kyoto Protocol mitigation regime. To analyse the aim of promoting sustainable development in developing countries, popular methods such as checklist, Multi-Criteria Analysis (MCA) and Cost-Benefit Analysis (CBA) were reviewed, a CBA of co-benefits of China’s CDM projects was carried out, and the Analytic Hierarchy Process (AHP) method was applied in an experimental study. The results showed that every method has its own advantages and problems. In other words, neither the CBA of co-benefits nor the AHP method alone is able to assess sustainable development in a completely satisfactory way. Currently, a bottom-up approach through engaging local stakeholders in CDM design and approval, combining a mandatory monitoring and evaluation of co-benefits, could be more effective for safeguarding local sustainable development than any consolidated standards. The future of the CDM is still unclear mainly due to uncertainties about the post-2012 regime. This thesis shows that there is more than sufficient reason for CDM to continue after 2012. Industrialised countries in general should make more substantial efforts to reduce their domestic emissions rather than blaming developing countries. For developing countries, learning from the CDM projects and further applying the knowledge, technology and experiences to their domestic development agenda could be more valuable than the present CER revenues. CDM can be an important starting point for developing countries to gradually make incremental greenhouse gas (GHG) reduction and limitation efforts. / QC 20110817

Ageing assessment of transformer insulation through oil test database analysis

Tee, Sheng Ji January 2016 (has links)
Transformer ageing is inevitable and it is a challenge for utilities to manage a large fleet of ageing transformers. This means the need for monitoring transformer condition. One of the most widely used methods is oil sampling and testing. Databases of oil test records hence manifest as a great source of information for facilitating transformer ageing assessment and asset management. In this work, databases from three UK utilities including about 4,600 transformers and 65,000 oil test entries were processed, cleaned and analysed. The procedures used could help asset managers in how to approach databases, such as the need for addressing oil contamination, measurement procedure change and oil treatment discontinuities. An early degradation phenomenon was detected in multiple databases/utilities, which was investigated and found to be caused by the adoption of hydrotreatment oil refining technique in the late 1980s. Asset managers may need to monitor more frequently the affected units and restructure long term plans. The work subsequently focused on population analyses which indicated higher voltage transformers (275 kV and 400 kV) are tested more frequently and for more parameters compared with lower voltage units (33 kV and 132 kV). Acidity is the parameter that shows the highest correlation with transformer in-service age. In addition, the influence of the length of oil test records on population ageing trends was studied. It is found that it is possible to have a representative population ageing trend even with a short period (e.g. two years) of oil test results if the transformer age profile is representative of the whole transformer population. Leading from population analyses, seasonal influence on moisture was investigated which implies the importance of incorporating oil sampling temperature for better interpretation of moisture as well as indirectly breakdown voltage records. A condition mismatch between dielectric dissipation factor and resistivity was also discovered which could mean the need for revising the current IEC 60422 oil maintenance guide. Finally, insulation condition ranking was performed through principal component analysis (PCA) and analytic hierarchy process (AHP). These two techniques were demonstrated to be not just capable alternatives to traditional empirical formula but also allow fast, objective interpretation in PCA case, as well as flexible and comprehensive (objective and subjective incorporations) analysis in AHP case.

Estruturas flutuantes para a exploração de campos de petróleo no mar(FPSO): apoio à decisão na escolha do sistema. / Decision aid methods applied to the selection of floating production storage and offloading system.

Marcos Fernando Garber 17 December 2002 (has links)
Freqüentemente os profissionais da construção naval tomam decisões para selecionar os elementos que devem ser especificados na composição de determinado projeto. Além da experiência e do conhecimento necessários para optar por um caminho adequado, a escolha deve atender eficientemente ao problema proposto e às preferências do projetista. A seleção de componentes do projeto de estruturas flutuantes para exploração de campos de petróleo no mar envolve aspectos objetivos e subjetivos. O trabalho apresenta e aplica alguns métodos de auxílio à tomada de decisão possibilitando ao projetista aprimorar sua sensibilidade. O objetivo da pesquisa é apresentar de forma sumária as duas bases para a decisão sobre o projeto, que são os métodos de apoio e os requisitos que as instalações FPSO devem atender, fornecendo como resultado um procedimento que permitirá aos usuários a melhor escolha dos componentes e aumentar a sensibilidade dos projetistas na seleção entre as possíveis opções (fazer totalmente novo ou aproveitar o existente). O trabalho apresenta uma revisão dos princípios da análise da decisão, informações sobre métodos de apoio à decisão, os dados de entrada do problema proposto, o método de projetos navais, os requisitos básicos para construção de estruturas flutuantes de exploração de petróleo no mar e os requisitos básicos para uma instalação FPSO. Para a solução do problema se aplicaram os métodos de árvore de decisão, para a parte correspondente às decisões sob risco e o método de análise hierárquica AHP para as decisões tomadas sob certeza. / Frequently, naval construction engineers take decisions to select the elements which must specified for the composition of a determined project. Besides the necessary experience and the knowledge to choose a proper way, the option must fulfil efficiently the problem requirements and the preferences of the designer. The choice of components in the design off-shore structures for production in sea oilfields, involves objective and subjective aspects. This work introduces and uses a few methods of decision aids, helping the designer to improve his sensibility. The objective of this research is to present in a simple way two foundations to decide about the project, which are the aid decision methods and the requirements which the FPSO (Floating Production Storage and Offloading System) must fulfil, supplying a procedure that enables the designer to take the best choice of components and to increase his sensibility referring to the selection among the possible options, wich are to make a completely new FPSO or to use an existing one. This work offers a revision of the principles of the decision analysis theory, the data input of the problem, the classic naval design method, the basic requirements to build floating structures to off-shore oil extraction, and the basic requirements for a FPSO installation. To solve the problem the decision tree method, for decision under risk, and the AHP (Analytic Hierarchy Process), for decision under certainty, were applied.

No. of bitstreams: 1 Rocha_LeticiaSantosda_D.pdf: 931669 bytes, checksum: a042ec9b535989c70d7e76efd1b732dc (MD5) Previous issue date: 2005 / Resumo: O Centro de Engenharia Biomédica (CEB) da Universidade Estadual de Campinas (UNICAMP) gerencia as atividades de manutenção (corretivas e preventivas) de um parque de cerca de 10.000 equipamentos médicos da área de saúde da Universidade, que inclui dois hospitais, dois centros médicos e uma escola de medicina. Para controlar estes serviços, o setor de Engenharia Clínica do CEB possui um sistema de gerenciamento baseado em uma máquina de estados, no qual todas as ordens de serviço (OS) são caracterizadas por trajetórias compostas pelos estados pelos quais cada OS passa durante a sua execução. Os estados são microprocessos ativados para solução de tarefas específicas. Cada mudança entre microprocessos é denominada, neste sistema, transicão. A nossa hipótese de trabalho foi que seria possível implementar no CEB um método de cálculo do custo das OS utilizando a técnica de custeio por atividade (Activity Based Costing, ABC). Para testar esta hipótese, tomamos as atividades (unidades fundamentais para a composição do custo ABC) equivalentes às transicões. Com esta abordagem fomos capazes de extrair o custo ABC das ordens de serviço, calcular o custo dos serviços prestados, exercitar o conceito de lucratividade (simulando valores de venda para cada OS com base no mercado), explicitar os custos das atividades dos indivíduos dentro dos diversos setores do CEB e estudar o impacto sobre o serviço (conjunto de atividades) de um determinado excedente "planejado", mediante o oferecimento de serviços para o mercado. Tendo em vista a possibilidade de calcular lucros para cada tipo de OS, pudemos estudar a aplicação de um processo de decisão, usando a técnica processo de hierarquia analítica (Ana/ytic Hierarchy Process, AHP) para decidir sobre a escolha da manutenção feita por terceiros ou feita pela equipe da casa. Os exercícios de cálculo de custos em diferentes condições ilustram a possibilidade de uso do ABC para gerenciamento baseado em atividade (Activity Based Management, ABM) e resultaram valores compatíveis com a realidade do sistema público universitário de saúde (e.g. custo das OS, custo do trabalho e atividades no CEB). Concluímos que a estratégia adotada de equivalência entre atividades e transições viabiliza e facilita a implementação do sistema ABC (o que confirma a nossa hipótese) e que, tendo em vista os preços praticados no mercado, um excedente da venda de serviço pode ser gerado, mesmo em um sistema público de saúde como o da UNICAMP, no qual os custos, essencialmente fixos (e.g. pessoal, depreciação, custos gerais), não podem ser reduzidos de modo trivial / Abstract: The Center for Biomedical Engineering (CEB) at 8tate University of Campinas (UNICAMP) manages the maintenance activities (corrective and preventive) of about 10,000 medical devices for the health care area of the university, which is comprised by two hospitais, two medical centers and a medicine school. In order to control these maintenance activities, the Clinical Engineering department makes use of a state machine-based management system in which the service orders (80) are characterized by trajectories (sequence of states) constructed while the 80 is processed. The states are microprocesses, which are activated to solve specific tasks. Each transition between two microprocesses (the state transition) is named, in short, a transition. We worked under the hypothesis that it would be feasible to implement at CEB a method for 80 costing based on the Activity-Based Costing (ABC) technique. To test our hypothesis, we made activity, fundamental token for ABC, equivalent to transition. With this approach, we were able to extract the ABC cost of each 80, to estimate cost for a specific service proposal, to exercise the concept of profitability by simulating selling costs for each 80 based in the current market, to explicit activity costs for individual jobs in CEB, and to study the impact of offering external services upon the total amount of activities of a certain "planned profit". By the analysis of 80 involving third party services, we studied the possibility of using the Analytic Hierarchy Process (AHP) technique to choose between third party or in-house services. The different conditions of ABC application in the present work iIIustrated the possibility of using ABC for Activity-Based Management (ABM), with results compatible with the expected figures for a public university health system (which validated our hypothesis). We conclude that our strategy of equivalence between activity and transition made the ABC feasible and relatively simple. We also found that according to the current market prices it is possible to envisage profit even in a health system such as in UNICAMP, in which costs are essentially fixed (e.g. staff, depreciation, general costs) / Doutorado / Engenharia Biomedica / Doutor em Engenharia Elétrica

Em paralelo a este cenário, o ambiente global está cada vez mais incerto, o que implica que as escolhas realizadas por estas empresas devem se adaptar aos novos desejos do mercado e, principalmente, devem manter o direcionamento de crescimento almejado pelas mesmas. Neste contexto conturbado, as ferramentas tradicionais utilizadas para a tomada de decisão, para selecionar e definir as prioridades são as análises econômico-financeira representadas pelo Valor Presente Líquido, a Taxa Interna de Retorno e o Payback. Apesar de estes itens serem métodos robustos e consistentes na avaliação de projetos de investimentos, eles focam apenas em um aspecto (o financeiro), e as empresas, atualmente, estão envolvidas em ambientes que precisam de uma abordagem mais ampla, contemplando outras visões e dimensões não presentes nos estudos financeiros. Ou seja, quando se faz uma análise de carteira de projetos alinhada ao planejamento estratégico, é necessário realizar uma abordagem multicritério envolvendo indicadores quantitativos e qualitativos e disponibilizando aos tomadores de decisão uma informação completa e padronizada de todos os projetos, uma vez que estas iniciativas não possuem características homogêneas, pois cada uma apresenta sua respectiva particularidade e, principalmente, está em diferentes estágios de maturidade. Aliado a estes pontos, é perceptível que o processo de seleção e priorização de projetos necessita de uma sistematização que garanta a esta decisão e a este Portfólio uma maior estabilidade e fidedignidade das informações. Neste trabalho, portanto, foi elaborada uma análise multivariada, mais especificamente, a utilização de sistemas de apoio à tomada de decisão. Foram escolhidos outros critérios além do econômico-financeiro, para suportar a seleção e priorização de projetos no atendimento dos objetivos estratégicos da organização e de seus stakeholders. / Currently, there is an enormous demand and pressure in selecting and defining priorities of investment projects to direct the long term growth in companies. In parallel to this scenario, the global environment continues to be uncertain which means that the choices executed by these companies must adapt to the new market desires and, mainly, keep the growth direction defined by them. In this hectic context, the traditional tools used to make decisions to select and define priorities are financial methods as Net Present Value, Internal Return Rates and Payback. Although these methods are robust and consistent in evaluating investment projects, these procedures are based only in one aspect which is financial, and the companies are involved in an environment that needs a broad approach considering other visions and dimensions which are not included in financial analysis, other words, when you perform a Portfolio analysis aligned with the strategic planning is necessary to head a multi-criteria approach which includes qualitative and quantitative performance indices providing to the decision makers comprehensive and standardized information for all projects, once these initiatives do not have homogeneous characteristics, as each initiative has its respective specificity, and they are in different stages of maturity. In addition to these points, it seems that the process of selecting and prioritizing projects requires a systematization to ensure to this decision and this Portfolio more stability and reliability of the information. In this study, therefore, it has been developed a multivariate analysis, more specifically, using systems to support decision making. It has been chosen criteria other than the economic-financial items, to support the selection and prioritization of projects meeting the strategic objectives of the organization and its stakeholders.

Selecting Housing Development Sites using Multi-Criteria Decision Analysis (MCDA) : A Case Study of Guangzhou, China

Wei, Da, Ding, Yijie January 2015 (has links)
Planning is of vital importance for the development urban areas to facilitate sustainable economic growth and social functions. The traditional, manual ways of planning that depend on biophysical data and use a hierarchical approach are no longer appropriate for site choice since information is rapidly updated today. Multi-criteria analysis (MCA) has been used for about two decades with geographic information systems (GIS) to analyze spatial problems. GIS-based Multi-Criteria Decision Analysis (MCDA) provides tools for assessing the inherent tradeoffs and mechanisms for incorporating and documenting the value judgments of interest groups and decision makers and is thus a more reasonable and scientific way for site selection to development. Guangzhou, the study area of this paper, is one of the fastest developing and largest cities located in Southern China. This research used the GIS-based MCDA approaches to find the appropriate sites for residential areas in Guangzhou. Satellite images, DEM and several thematic maps of Guangzhou were used in this research. Using different methods and technologies, the data were used to create constraint and factor maps for multi-criteria analysis. After building the MCA model, the weights for multi-criteria analysis were obtained through an analytic hierarchy process (AHP) by comparing the importance of every two factors. Finally, a suitability map for housing development was generated. The result indicates that with the help of GIS and remote sensing technologies, the process of site selection and urban planning can be done in a more effective and scientific way. The limitation and future perspective of GIS based MCDA methods are discussed.
