Evaluation on Transfer Efficiency at Integrated Transport Terminals through Multilevel Grey Evaluation

AbstractTransfer efficiency in integrated transportation terminal is greatly important for both passengers and operational companies. In this paper, we proposed various criteria and a hierarchy index system to evaluate the performance of the transfer condition inside Beijing South Railway Station. To make the assessment more scientific, we assign weightings to each of them by integrated weighting method. Then we use an evaluation method, Multi-level Grey Evaluation, to calculate the performance indexes of different transfer modes in the station and further we compare the ranking results of transfer efficiency of different transfer modes

Supporting sustainable transport appraisals using stakeholder involvement and mcda

Appraisal processes for transport initiatives are often characterised by their complexity involving a wide range of impacts that need to be addressed and many stakeholders that attempt to influence the decisions to be made. The increasing interest for the environment and sustainable development in general has stressed the need for taking a broad perspective into account when addressing transport initiatives. This means that economic, social and environmental dimensions need to be considered simultaneously in the appraisal process. The focus on incorporating such sustainability considerations has set new demands for the appraisal process and has revealed an increasing need for involving stakeholders in the decision support process to capture all aspects of the often complex decision problems. Conventional appraisals within the transport area are often only based on cost-benefit analysis, which captures the impacts that can be assigned with a monetary value. Thus there is a need for a decision support system that is able to assess the effect of other types of impacts as well and include this in the appraisal. This paper seeks to fill this gap in research by proposing a methodology making use of planning workshops and multi-criteria decision analysis in combination to improve the decision support. In order to serve the purpose of promoting a more sustainable transport planning approach a proposal is made for how the methodology can be integrated in the current practice for appraisal of infrastructure projects in Denmark (and countries with similar approaches). The paper concludes that the approach allowing for active stakeholder participation in the appraisal process can serve as a helpful and effective decision support system in the quest for more sustainable solutions to transport problems

Estudo de métodos de análise multicritério aplicados à gestão de projetos

Monografia (graduação)—Universidade de Brasília, Faculdade De Tecnologia, Departamento De Engenharia De Produção, 2014O presente trabalho se propõe a realizar uma análise dos métodos de decisão baseados em análise multicritério (Multi Criteria Decision Analysis - MCDA) aplicados no âmbito da gestão de projetos. São estudados casos diversos de problemas relacionados a projetos, como hierarquização e classificação de atividades, alocação de orçamento, dentre outros. Em cada análise, são identificados os fatores que influenciaram o tomador de decisão a escolher determinado método MCDA. Com essas informações, é possível estabelecer uma estratificação dos dados coletados, identificando em quais situações cada método MCDA estudado é mais adequado. Isso permitirá ao tomador de decisão definir com maior consistência e eficiência o método aplicável à sua situação problema. Identificou-se que o assunto mais abordado nos artigos estudados foi o problema seleção de projetos, sendo os métodos mais utilizados o PROMETHEE e o ELECTRE. ___________________________________________________________________________________ ABSTRACTThe purpose of this work is to analyze the decision methods based on multi criteria analysis (Multi Criteria Decision Analysis – MCDA) applied in project management. Several problems related to projects are studied, such as activities sorting and ranking, budget allocation, among others. In each analysis, the factors which influenced the decision maker to choose a specific MCDA method are identified. With these informations, it is possible to establish a stratification of the collected data, in order to identify in which situations each MCDA method studied is more adequate. This will enable the decision maker to define with more consistency and efficiency the applicable method in accordance with the problem situation. The subject most discussed in the studied papers was the project selection problem, and the methods most applied were the PROMETHEE/ELECTRE

Flexible decision support for sustainable development: the SUSTAIN framework model

Sustainable transport planning necessitates a rethinking of traditional decision making. This is conventionally supported by cost-benefit analysis (CBA) that systematically quantifies and compares the various benefits and costs generated by a transportation project or policy. Generally, CBA has been found less useful for the handling and assessment of multiple, often conflicting objectives or criteria like environmental or social issues intrinsically difficult to quantify. Therefore, it is necessary to broaden the decision making process beyond merely economic factors. The Danish research project on Sustainable National Transport Planning (SUSTAIN 2012-2016) seeks, among other things, to develop a flexible decision support model (tool) to include and assess sustainability planning criteria in a socio-economic framework, which makes up the SUSTAIN Framework Model (SFM). The SFM comprises two parts, namely a process part consisting of stakeholder involvement and an analytical tools part consisting of an Excel-based software model. The latter employs the use of CBA, multi-criteria decision analysis and risk analysis techniques enabling the assessment of non-quantifiable impacts within a decision support context. The concept of a planning workshop is introduced as relevant for dealing with the various strategic elements not included in the CBA. Moreover, SUSTAIN is rooted in cross-disciplinary sustainability research that recognises that a transition towards sustainability must involve normative, analytical and strategic considerations to be successful. The paper concludes that the SFM can contribute to the analytical dimension. Thus, the framework model allows for the appraisal of planning criteria (indicator sets) in a socio-economic appraisal setting for national sustainable transport planning which enhances both the concept and principles of sustainable development while at the same time it provides a flexible decisionsupport tool for policy-makers

A knowledge-based decision support system for sustainable city livability evaluation

The real estate industry is an important indicator of national economies and is influenced by the environment in which it operates. Several countries were seriously affected by the most recent international financial crisis, including Portugal. Nevertheless, it is still an interesting area to invest in, in spite of the challenges cities may face nowadays that influence their sustainable livability. For this reason, it seems logical to develop and apply methodologies aimed at evaluating sustainable city livability. It is worth noting, however, that there are methodological limitations typically associated with the majority of the current applications (e.g. how to select and weight criteria in the evaluation), which have been hampering the progress. Hence, this dissertation aims to develop a knowledge-based decision support system to evaluate sustainable city livability, in a transparent and informed way. To achieve this goal, it combines cognitive mapping techniques and the Analytic Hierarchy Process (AHP). The advantages and limitations of this integrative evaluation model are also analyzed and discussed.O mercado imobiliário é um indicador importante das economias mundiais e é influenciado pelo ambiente em que opera. Muitos foram os países seriamente afetados pela mais recente crise financeira internacional, incluindo Portugal. Não obstante, este continua a ser uma área de investimento interessante, ainda que, hoje em dia, as cidades possam enfrentar desafios que influenciam a sua habitabilidade sustentável. Por essa razão, parece lógico o desenvolvimento e a aplicação de metodologias que permitam avaliar a sustentabilidade habitacional de uma área urbana. No entanto, limitações metodológicas comuns à maioria das aplicações (e.g. processo de seleção e ponderação dos critérios de avaliação) têm dificultado os progressos alcançados. Assim, a presente dissertação pretende desenvolver um “termómetro” de habitabilidade sustentável que, de forma informada e transparente, permita apoiar a tomada de decisão no mercado imobiliário urbano, através da combinação do uso integrado de técnicas de mapeamento cognitivo e da metodologia Analytic Hierarchy Process (AHP). As vantagens e as limitações do uso deste sistema integrativo de avaliação serão também analisadas e discutidas
