Using GIS-based Multi-criteria Analysis for Optimal Site Selection fora Sewage Treatment PlantDI, ZHAO January 2015 (has links)
Geographic Information System (GIS) technologies and remote sensing (RS) technologies have developed rapidly in recent years, and they have been widely used indaily life of ordinary people. The combination of these two remarkable technologies isuseful for location decision making and has been applied in different kinds of study cases.Guangyuan is one of the fastest developing cities in the southwest of China. Especiallyafter the Wenchuan earthquake in 2008, the development in economic and urbanreconstruction increased rapidly. Many infrastructure constructions and the reformprojects are in progress. At the same time, China's urban sewage treatment facilities areseriously inadequate. Only a small percentage of sewage has been treated by sewagetreatment plants in China. So the purpose of this study is to select an optimal site for asewage treatment plant in Guangyuan in a scientific way.In this particular study, based on GIS software and GIS-based multi-criteria analysis(MCA), a decision making model has been built for optimal site selection for a sewagetreatment plant. Two types of data were used in this study. Digital elevation model andsatellite image, several factor maps and constraint maps were created for the final analysis.The analytic hierarchy process was used to apply the weights for each factor along withformula method, in order to get the best result and find the optimal site. Finally, a MCAmodel has been made to be an example for future similar studies.In the end, an optimal site has been selected. Although aims are achieved in this study,there are still some limitations in different perspectives of the study. In the future, moreprecise data can be used in MCA studies, data limitations could be reduced with thedevelopment of RS techniques. In the future, more similar studies will be finished, whichmeans more scientific papers can provide reliable references of determining the criteriaand weights.

Comparison of fuzzy and crisp analytic hierarchy process (AHP) methods for spatial multicriteria decision analysis in GISKordi, Maryam January 2008 (has links)
There are a number of decision making problems in which Geographical Information System (GIS) has employed to organize and facilitate the procedure of analyzing the problem. These GIS-based decision problems which typically include a number of different criteria and alternatives are generally analyzed by Multicriteria Decision Analysis (MCDA).Different locations within a geographical area represent the alternatives by which the overall goal of the project is achieved. The quality of achieving the goal is evaluated by a set of criteria which should be considered in the work. Analytic Hierarchy Process (AHP) which is a powerful method of MCDA generally can organize spatial problems and decides which alternatives are most suitable for the defined problems. However due to some intrinsic uncertainty in the method, a number of authors suggest fuzzifying the method while others are against fuzzification of the AHP. The debate over fuzzifying AHP is going on and attempt for finding that was mostly in theory, and little, if any; practical comparison between the AHP and fuzzified AHP has done. This work presents a practical comparison of AHP and fuzzy AHP in a GIS-based problem, case study, for locating a dam in Costa Rica, considering different criteria. In order to perform the AHP and fuzzy AHP in the GIS-based problem and calculating weights of the criteria by the methods, some computer codes have written and developed in MATLAB. The comparisons between the AHP and fuzzy AHP methods are done on result weights and on the result final maps. The comparison between the weights is repeated on different levels of uncertainty in fuzzy AHP then all the results are compared with the result of AHP method. Also this study for checking the effect of fuzzification on results is suggested Chi-Square test as a suitable tool. Comparisons between the resulting weights of the AHP and fuzzy AHP methods show some differences between the methods. Furthermore, the Chi-Square test shows that the higher level of uncertainty in the fuzzy AHP, the greater the difference in results between the AHP and fuzzy AHP methods.

The Implications of Park and Ride for Urban Development Strategies in major metropolitan areas in New ZealandWoods, Stuart George January 2006 (has links)
Many cities, including some in New Zealand, are investigating, developing or implementing urban form strategies and, separately, Park and Ride systems. These two matters are not generally considered alongside one another. This paper explores the relationship and interactions between urban form and Park and Ride systems through the identification of objectives for each, and considering the degree to which objectives of various urban form types may be achieved with different types of Park and Ride systems. The purpose of this research project is to investigate and develop a predictive methodology that would allow the identification of the most suitable Park and Ride system (from a proposed classification scheme) for a given set of urban form objectives. Classification systems for urban form and Park and Ride systems are proposed in light of information from an extensive literature and information review. They are used as a basis for an Assessment Framework Matrix of urban form type against Park and Ride type. The matrix is populated from a spreadsheet-based analysis process, which considers the degree of achievement of urban form objectives by various Park and Ride categories. This process is hampered by the lack of (easily accessible) data, particularly for strategic assessment of existing Park and Ride systems worldwide. A range of tests are conducted on the proposed Assessment Framework Matrix using real cities, a range of hypothetical urban areas, and several sensitivity tests. Subsequently, a case study applies the matrix to Christchurch, New Zealand. The main findings of this research project indicate that the proposed methodology works, needs refining with better data, could be useable in public or stakeholder engagement processes, and would benefit from a "User Manual" and some simplification. The case study tentatively indicates a recommended Park and Ride system type for Christchurch.

SPATIAL PRIORITIZATION FOR INVASIVE PLANT MANAGEMENTLevin-Nielsen, Abraham Michael 01 January 2012 (has links)
Invasive exotic plant species have been recognized as serious threats to ecosystems. Extensive research on invasive exotic plant species has primarily focused on the impacts, characteristics, and potential treatments. Decision tools and management models that incorporate these findings often lack input from managers and have limited use in differing invasion scenarios. Therefore, in this study, I created a scientifically-driven framework that incorporates expert input to prioritize watersheds for management within the Inner Bluegrass region of Kentucky. The widely distributed invasive exotic plant Amur honeysuckle (Lonicera maackii) was used as an example species. The framework is built around the Analytic Hierarchy Process and highlights areas in most need of invasive exotic plant management by incorporating weighted landscape variables associated with the invasion process. Results of the prioritization provide useful information for natural resource managers by aiding in the development of control strategies while also creating a valuable framework that can be adapted to various invasive exotic plant species.

SOCIO-ECONOMIC STUDY OF COMMUNITY FORESTS IN MID HILLS REGION OF NEPALK.C., Birendra 01 January 2012 (has links)
This research looks at some issues confronting community forestry in Nepal. Analytic Hierarchy Process (AHP) was used to analyze the issues confronting community forestry in mid hills region of Nepal. Results indicate that experts as well as local community users think positive aspects of community forestry to be more important than its negative aspects. In addition, through the comparison of three forest types, Alnus nepalensis found to be the most important forest type for conservation and Schima-Castanopsis to be the most important forest type for local benefits. Similarly, results also indicate that increase in carbon prices lengthen an optimal rotation age. Also, Land Expectation Value (LEV) increases substantially with the increase in carbon prices.

Selection of a Logistics Service Provider Based on Analytic Hierarchy Process (AHP) Approach : A case study of Swedish Coffee Manufacturer—GevaliaYe, Heshan, Wu, Jiading January 2014 (has links)
Logistics outsourcing has been applied in practices by enterprises for decades, but its efficiency is always restricted because logistics service providers (LSPs) often only have a single function such as delivery or warehousing. In the last few years, LSPs have upgraded their capabilities to support some other logistics services including value-added services, materials management, information-related services etc. The purpose of this thesis is to identify the differences between self-built logistics system and outsourcing logistics system by using the Strengths Weaknesses Opportunities Threats (SWOT) strategic analysis; and figure out how to apply the Analytic Hierarchy Process (AHP) to make an appropriate selection among LSPs that based on the single-case study of Gevalia. Both quantitative and qualitative methods have been used in this study, authors expect to describe and explore the application of AHP approach regarding to the case company which implements outsourcing logistics system. Accordingly, it could be a good idea for case company to implement the mixed mode of self-built and outsourcing logistics system after using the SWOT strategic analysis. In addition, the production and logistics manager of case company emphasized that the five selection criteria including “compatibility”, “delivery performance”, “location”, “management” and “cost” should be considered as a priority among other different criterion when he selected a LSP. As a result, it will be efficient and effective for us to simulate a best decision for those industrial manufacturing enterprises to achieve a path regarding to the selection of the best logistics partner that based on the significant AHP approach.

A methodological approach for indicator-based sustainable transport assessmentCastillo, Nicodemus Herb January 2004 (has links)
Sustainable transport is now a popular goal of transport planning. As with any aspiration, systems and mechanisms are required to assess and gauge success in achieving this policy goal. There is increasing reliance on sustainable transport indicators as appropriate tools for this purpose. The usefulness and credibility of any indicator-based assessment will undoubtedly depend on the specific indicators utilised. As such, indicators must be selected carefully to maximise their contribution to the sustainable transport decision making process. A review of current applications of sustainable transport indicators has revealed however, that they are typically selected in an ad hoc and arbitrary fashion. Development of a framework that facilitates transparent and systematic indicator selection would therefore represent a significant advance in transport research. In that regard, this thesis presents the Evaluative and Logical Approach to Sustainable Transport Indicator Compilation (ELASTIC), a methodological framework which provides a flexible, participatory and systematic mechanism for identifying and selecting key sustainable transport indicators. The output of ELASTIC is the Transport Sustainability Profile (TSP), a small un-aggregated suite of sustainable transport indicators which together can provide a snapshot of the sustainability of a transport system. Using various multi-criteria and statistical techniques, ELASTIC applies a robust process to evaluate and select indicators based on their analytical soundness and their relevance to key objectives of sustainable transport. A generic and transferable tool, ELASTIC is capable of application at different geographical scales as well as to non-transport sustainability assessment. For the purpose of this research, the framework is demonstrated through application to England, UK where the judgements of relevant Academics and Transport Planners are elicited and entered into the ELASTIC framework to systematically select a subset of 15 indicators from an initial set of 200. By disaggregating the sample of stakeholders into regional groupings, different context-specific suites of indicators for the regional groupings were also derived. The demonstration confirms ELASTIC to be an inclusive and practical approach to compiling a suite of sustainable transport indicators specific to context and which reflects the unique values of key stakeholders.

Previous issue date: 2008-10-27 / The objective of this dissertation is to propose a Multi Criteria Decision Aid Model to be used by the costumers of the travel agencies and help them to choose the best package travel. The main objective is to contribute for the simplification of the travel package decision choice from the identification of the models of values and preference of the customers and applying them to the existing package. It is used the Analytic Hierarchy Process (AHP) method to structuralize a decision hierarchic model composed by six criteria (package cost, hotel category, security of the city, travel time, direct flight and
position in ranking of the 10 most visited destination) and five real alternatives of packages for a holiday of three days created from travel agency data. The decision analysis was
realized for the choice of a travel package by a group composed by two couples that regularly travels together, to which was asked to do a pairwise judgment of the criteria and
the alternatives. The mains results show that, although been a group that travels together, there are different models of values in the weights of the criteria and a certain convergence
in the scales of preferences of the alternatives in the criteria. It was not pointed a dominant alternative for all the members of the group separately, but an analysis of a total utility of
the group shows a classification and an order of the travel packages and an alternative clearly in front of the others. The sensitivity analysis revels that there are changes in the
ranking, but the two alternatives best classified in the normal analysis are the same ones in the sensitivity analysis, although with the positions changed. The analysis also led to a
simplification of the process with the exclusion of alternatives dominated for the others ones. As main conclusion, it is evaluated that the model and method suggested allow a
simplification of the decision process in the choice of travel packages / O objetivo deste trabalho ? realizar uma modelagem de an?lise de decis?o multicriterial para apoio na decis?o para escolha de pacote de viagem por clientes das ag?ncias de turismos. O objetivo central ? contribuir na simplifica??o da decis?o da escolha de pacotes de viagens a partir da identifica??o dos modelos de valores e prefer?ncias dos clientes e
aplic?-los em seguida aos pacotes existentes. ? utilizado o m?todo do Processo de Hierarquia Anal?tica (AHP Analytic Hierarchy Process) para estruturar um modelo hier?rquico de decis?o composto por seis crit?rios (custo do pacote, categoria do hotel, seguran?a da cidade, tempo de viagem, v?o direto, posi??o no ranking dos 10 mais destinos) e cinco alternativas reais de pacotes para fim de semana prolongado criadas a partir de dados de ag?ncia de viagens. A an?lise de decis?o foi realizada para a escolha do pacote por um grupo composto por dois casais que viajam regularmente juntos, aos quais foi solicitado que fizessem o julgamento par a par dos crit?rios e das alternativas. Os principais resultados revelam que, embora seja um grupo que viaja junto, h? diferentes
modelos de valores nos pesos dos crit?rios e certa converg?ncia nas escalas de prefer?ncias das alternativas nos crit?rios. N?o houve uma alternativa dominante para todos os membros do grupo isoladamente, mas em uma an?lise de uma utilidade total do grupo h? uma classifica??o e ordenamento dos pacotes e uma alternativa claramente ? frente das demais. A an?lise de sensibilidade mostra que h? mudan?as nesse quadro, mas as duas mais bem classificadas na an?lise normal s?o as mesmas com a an?lise de sensibilidade, embora com mudan?a de posi??o. A an?lise levou tamb?m a simplificar o processo com a exclus?o de alternativas dominadas por todas as demais. Como principal conclus?o, avaliase que a modelagem e m?todo sugerido permitem uma simplifica??o do processo de decis?o na escolha de pacotes de viagens

Dinâmica e análise de fragilidade ambiental, banhado da reserva biológica de São Donato - RS / Dynamics and analysis of environmental fragility, Marsh of the biological reserve of São Donato - RSBittencourt, Daniela Zanetti January 2017 (has links)
A Reserva Biológica (REBIO) de São Donato é uma Unidade de Conservação localizada na fronteira oeste do Rio Grande do Sul, no trecho médio da bacia do rio Uruguai, no bioma Pampa. A área da REBIO é constituída por uma área úmida – banhado – característico do Pampa. Entretanto, desde o seu decreto em 1975, o banhado vem sofrendo impactos da rizicultura, essa região é a maior produtora do estado. Assim, o objetivo geral dessa dissertação é analisar a dinâmica e a fragilidade ambiental da Reserva Biológica de São Donato, a partir de geoprocessamento. Para atingir esse objetivo foram utilizados: dados de precipitação diários e imagens orbitais, de 1984 a 2016, que indicassem inundação no banhado e sua sub-região hidrográfica; reconhecimento de campo; análise de uso e cobertura do solo do raio de amortecimento da REBIO; análise da fragilidade ambiental a partir da metodologia do Processo Analítico Hierárquico (AHP). Os resultados de análise da inundação do banhado e sua sub-região hidrográfica indicaram três padrões: um padrão regional, que afeta grande parte do trecho médio e alto da bacia do rio Uruguai; um padrão de inundação sub-regional, que compreende a sub-região hidrográfica dos rios Butuí-Icamaquã; um padrão que afeta a área local que compreende o banhado da REBIO de São Donato. As análises do uso e cobertura do solo e da fragilidade ambiental indicaram que as áreas mais frágeis da REBIO correspondem ao banhado e sua vegetação adaptada a umidade, e áreas de planícies de inundação. A avaliação do AHP para a análise da Fragilidade Ambiental se mostrou coesa, confirmando observações realizadas principalmente com relação ao impacto ambiental gerado pelo cultivo de arroz. Espera-se que as informações possam contribuir para estudos futuros de planejamento e gestão da área, e como base para a elaboração do Plano de Manejo da REBIO de São Donato. / The San Donato Biological Reserve (REBIO) is a Conservation Unit located on the western border of Rio Grande do Sul, in the middle stretch of the Uruguay River basin, in the Pampa biome. The area of the REBIO is constituted by a wetland - marsh - characteristic of the Pampa. However, since its decree in 1975, the marsh has been suffering from the impacts of rice cultivation, this region is the largest in the state. Thus, the general objective of this dissertation is to analyze the dynamics and environmental fragility of the San Donato Biological Reserve, based on geoprocessing. To achieve this objective, daily precipitation data and orbital images from 1984 to 2016 were used to indicate flooding in the marsh and its sub-river basin; Field recognition; Use analysis and soil cover of the REBIO Damping Ray; Analysis of the environmental fragility from the Analytic Hierarchy Process (AHP) methodology. The results of flood analysis of the marsh and its hydrographic sub-region indicated three patterns: a regional pattern, which affects much of the middle and upper reaches of the Uruguay River basin; A subregional flood pattern comprising the sub-river basin of the Butuí-Icamaquã rivers; A pattern that affects the local area comprising the marsh of San Donato Biological Reserve. The analyzes of soil use and cover and environmental fragility indicated that the most fragile areas of REBIO correspond to the wetland and its vegetation adapted to humidity and floodplain areas. The evaluation of the AHP for the analysis of the Environmental Fragility showed to be cohesive, confirming observations made mainly in relation to the environmental impact generated by rice cultivation. It is hoped that the information may contribute to future planning and management studies of the area, and as a basis for the elaboration of the São Donato REBIO Management Plan.
