Proposta metodológica para mapeamento de vulnerabilidade à inundação

Ramos, Paola de Assis de Souza January 2017 (has links)
A expansão dos centros urbanos, determinada pela demanda de áreas, está fortemente associada à vulnerabilidade da população. Este avanço, muitas vezes ocorre em direção a ambientes frágeis como margens de rios, encostas e mananciais. Desta maneira, as mudanças no ambiente, deflagradas pelas atividades antrópicas, têm contribuído fortemente para maior exposição da população e consequente impactos relacionados às inundações, em relação às inundações. Os mapeamentos de vulnerabilidade são medidas não estruturais muito importantes para avaliar as características de determinada população, que as tornam mais ou menos propensas aos impactos de uma inundação. Desta forma, o objetivo principal deste trabalho é propor uma metodologia, baseada na utilização de SIG, para mapeamento de vulnerabilidade à inundação a partir da integração de dados censitários e de outras fontes, usando como estudo de caso o município de Igrejinha, RS. Determinou-se- como unidade de estudo a mancha urbana presente em cada setor censitário do IBGE. Foram elaborados 10 indicadores distribuídos em 3 dimensões que buscaram avaliar aspectos demográficos, sociais e de infraestrutura e saneamento. Os dados utilizados são provenientes do IBGE e também de outras pesquisas realizadas no município por outros autores. Compreende-se nesta pesquisa que cada indicador possui uma importância diferente e atribui-se um peso especifico para cada indicador e dimensão pelo método Analytic Hierarchy Process (AHP). Os pesos foram atribuídos por especialistas da área e por agentes de Proteção e Defesa Civil. Os pesos foram atribuídos para duas fases distintas do gerenciamento de um desastre: resposta e recuperação. Através de ferramentas presente em SIG, foi utilizado o método dasimétrico para os dados à mancha urbana de cada setor censitário. Como resultado obteve-se um mapa de cada indicador e dimensão, bem como o mapa final de vulnerabilidade à inundação. Foram gerados mapas com pesos atribuídos para resposta e para recuperação. Em cada mapa gerado pode-se obter as áreas mais vulneráveis da área de estudo, que corresponderam as Zonas de Interesse Social de Igrejinha. Para observar certos aspectos que poderiam acarretar na vulnerabilidade, segundo o indicadores utilizados, foi empregada a ferramenta Google Street View. Devido ao seu baixo custo, bem como a facilidade da obtenção dos dados, a metodologia proposta pode ser replicada em qualquer município brasileiro. / The expansion of urban centers, determined by area demand, is strongly associated with the vulnerability of the population. This breakthrough often occurs toward fragile environments such as riverbanks, slopes and springs. In this way, environmental changes triggered by anthropic activitythe changes in the environment, triggered by the anthropic activities, have contributed strongly to greater exposure of the population and consequent flood impacts. Vulnerability mappings are very important non-structural measures to assess the characteristics of a given population, which make them more or less prone to the impacts of a flood. Along these lines, the main objective of this work is to propose a methodology, based on the use of GIS, to map vulnerability to flood, from the integration of census data and other sources, using as a case study, the municipality of Igrejinha, RS. The urban spot present in each IBGE census tract was used as the unit of study. Ten indicators were elaborated in three dimensions that sought to evaluate demographic, social, and infrastructure and sanitation aspects. The data used come from IBGE and also from other surveys conducted in the municipality by other authors. It is understood in this research that each indicator has a different importance and is assigned a specific weight for each indicator and dimension by the Analytic Hierarchy Process (AHP) method. The weights were assigned by specialists in the area and by Civil Protection and Defense agents to two distinct phases of disaster management: response and recovery. By means of tools present in GIS, the dasymetric method was used for the data to the urban spot of each census sector. As a result, a map of each indicator and size was obtained, as well as the final map of vulnerability to flooding. Maps with weights assigned for response and retrieval were generated. In each generated map, it is possible to observe the most vulnerable areas of the study area, which corresponded to the Igrejinha Social Interest Zones. In order to observe certain aspects that could lead to vulnerability, according to the indicators used, the Google Street View tool was used. Due to its low cost, as well as the ease of obtaining the data, the proposed methodology can be replicated in any Brazilian municipality.

Introducing GIS and Multi-criteria analysis in road path planning process in Nigeria : A case study of Lokoja, Kogi State

Anavberokhai, Isah January 2008 (has links)
<p>In planning a suitable road network, planners put into consideration factors like gradients or slope of the area, available land-use and soil type, community or national landmarks and governmental interest. These different considerations and interest make the planning process complex and as such there might be confusion of interest in the decision making. The use of GIS and Multi-criteria analysis has helped planners to achieve desired and more accurate results and as such reducing the complex nature in the planning process allowing different stakeholders to reach a general conclusion.</p><p>Multi-criteria analysis (MCA) prevents the imposition of limit on the form of criteria and gives opportunity to decision makers to enter their own judgments.

A Study on the Strategies of Value-added Supply Chain Management in Nuclear Medicine

Chang, Chung-shihn 24 June 2010 (has links)
Since the Canadian nuclear reactor ¡§NRU¡¨ was shut down on 14th May, 2009, the global Moly shortage has occurred for a year. The crisis was not only an impact for the patients of the hospitals in Taiwan, but also decreased the sales and margin profit of the nuclear medicine distributors. The S company, a leading and monopolistical distributor in Taiwan, was no longer reliable for its customers because of the nuclear medicine shortage. Actually it looks like the advantage of the S company is lost and the reputation is damaged. This research is trying to figure out how a nuclear medicine distributor like the S company can pursue some effective supply chain strategies to turn around and keep the growth of profit. AHP is the study method for this research. But at first we¡¦ll plan some strategies and tactics for the nuclear medicine distributors (especial the S company), according to Potters¡¦ competition theory and the resource based view of the firm. And then develop the two levels structure for the AHP study in this research. The factors of upper level are 4 strategies, like ¡§Research & Development Strategy¡¨ etc. The factors of lower level are 18 tactics or plans just like ¡§Try to acquire new technology from the advanced radiopharmaceutical institutes¡¨ etc. The AHP will be performed by surveys of experts¡¦ opinions, including both qualitative and quantitative surveys. Five different groups of experts were sampling and chosen for the surveys. By the AHP, the two most weights of the tactics are determined. They are ¡§Integrate individual (country) procurement into multinational procurement for reducing cost¡¨ and ¡§Actively globalized procurement, and monopolistically securing the sources¡¨. Besides, we can discover more valuable opinions from the qualitative analysis of the expert¡¦s surveys. So the results of this research, the effective and advanced strategies and tactics, are the first securing more reliable sources of the nuclear medicine and the second improving globalized procurement. And then try to enhance marketing and strengthen customer relationship. These will be expected to be helpful on both distributors¡¦ profit and customers¡¦ satisfaction.
