Full textNumerous optimization problems involve systems with multiple and often contradictory criteria. Such contradictory criteria have been an issue for marine/naval engineering design studies for many years. This problem becomes more important when one considers novel ship types with very limited or no operational record. A number of approaches have been proposed to overcome these multiple criteria design optimization problems. This Thesis follows the Parameter Space Investigation (PSI) technique to address these problems. The PSI method is implemented with a software package called MOVI (Multi-criteria Optimization and Vector Identification). Two marine/naval engineering design optimization models were investigated using the PSI technique along with the MOVI software. The first example was a bulk carrier design model which was previously studied with other optimization methods. This model, which was selected due to its relatively small dimensionality and the availability of existing studies, was utilized in order to demonstrate and validate the features of the proposed approach. A more realistic example was based on the "MIT Functional Ship Design Synthesis Model" with a greater number of parameters, criteria, and functional constraints. A series of optimization studies conducted for this model demonstrated that the proposed approach can be implemented in a naval ship design environment and can lead to a large design parameter space exploration with minimum computational effort.

Full textThe pearl oyster Pinctada martensii or Pinctada fucata is the oyster for produce the South China Sea Pearl, and the production of pearl oyster Pinctada martensii plays a key role for the economic and social welfare of the coastal areas. To guarantee both rich and sustainability of providing pearl oyster productions, addressing the suitable areas for aquaculture is a very important consideration in any aquaculture activities. Relatively rarely, in the case of site selection research, the researchers use GIS analysis to identify suitable sites in fishery industry in China. Therefore, I decided to help the local government to search suitable sites form the view of GIS context. This study was conducted to find the optimal sites for suspended culture of pearl oyster Pinctada martensii using GIS-based multi-criteria analysis. The original idea came from the research of Radiarta and his colleagues in 2008 in Japan. Most of the parameters in the GIS model were extracted from remote sensing data (Moderate Resolution Imaging Spectroradiometer and Landsat 7). Eleven thematic layers were arranged into three sub-models, namely: biophysical model, social-economic model and constraint model. The biophysical model includes sea surface temperature, chlorophyll-α concentration, suspended sediment concentration and bathymetry. The criteria in the social-economic model are distance to cities and towns and distance to piers. The constraint model was used to exclude the places from the research area where the natural conditions cannot be fulfilled for the development of pearl oyster aquaculture; it contains river mouth, tourism area, harbor, salt fields / shrimp ponds, and non-related water area. Finally those GIS sub-models were used to address the optimal sites for pearl oyster Pinctada martensii culture by using weighted linear combination evaluation. In the final result, suitability levels were arranged from 1 (least suitable) to 8 (most suitable), and about 2.4% of the total potential area had the higher levels (level 6 and 7). These areas were considered to be the places that have the most suitable conditions for pearl oyster Pinctada martensii for costal water of Yingpan.

Full textDiplomityö pyrkii konstruktiivisen tutkimuksen avulla soveltamaan monikriteerisiä päätösanalyysiteorioita (Multi Criteria Decision Analysis — MCDA) kiinteistöportfoliohallinnan päätöksentekoon. Teorioita sovelletaan työssä kehittämällä kiinteistöportfoliohallinnan päätöksentekoa avustava malli. MCDA on oppi metodeista ja lähestymistavoista, joissa eri vaihtoehtojen paremmuutta arvioidaan suhteessa päätöksentekijän asettamiin tavoitteisiin. Teorioiden käsittelemien päätösongelmien luonteeseen kuuluvat useat ristiriitaiset ja yhteismitattomat kriteerit, jotka tekevät päätöksenteosta erittäin haasteellista. MCDA:n tuoma arvo päätöksentekoon syntyy sen jäsennellystä ja selkeästä tavasta käsitellä päätösongelmaa, minkä johdosta päätöksentekijä tulee tietoisemmaksi itse päätösongelmasta sekä omista ja muiden sidosryhmien arvoista ja tavoitteista. Monikriteerisiä päätösanalyysiteorioita on sovellettu aiemmin esimerkiksi infrapuolella siltojen kunnossapitoprojektien valintaan. Kehitetyn matemaattisen mallin avulla pystyttiin analyyttisesti arvioimaan kunkin vaihtoehdon hyvyyttä ja poimimaan siltakannasta eniten päätöksentekijän tavoitteita vastaavat kohteet. Tutkimus toteutettiin kolmessa osiossa, joista ensimmäisessä selvitettiin MCDA:n perusteet määrittämällä kirjallisuuskatsauksen avulla päätöksentekijän preferenssejä mallintava MAVT-prosessi. Kirjallisuuskatsauksen jälkeen seurasi työn empiirinen osio, mikä pyrki haastatteluiden avulla selvittämään kiinteistöportfoliohallinnan päätöksentekoa ohjaavat kriteerit ja niiden toteutumista mittaavat attribuutit. Työ keskittyi käsittelemään vain kiinteistökohtaisten sisäsyntyisten tekijöiden vaikutusta kiinteistöportfoliohallintaan. Lopuksi empiriasta saatujen tuloksien pohjalta kuvattiin MAVT prosessi kyseessä olevassa kontekstissa ja kehitettiin esimerkkimalli kiinteistöportfoliohallinnan päätöksenteon tueksi. Esitetty malli on suunnattu yksityisille kiinteistönomistajille, jotka omistavat liike- ja toimistokiinteistöjä vain sijoitusmielessä. Tutkimuksen tuloksena saatiin viisi kiinteistöportfoliohallinnan päätöksentekoa ohjaavaa kriteeriä: makrosijainti, mikrosijainti, sopimushinta, kiinteistön korjaustarpeet ja kiinteistön kehittymiskyky. Sijainti kriteerit pyrkivät huomioimaan sekä makroympäristön kehittymisen että kiinteistön saavutettavuuden. Sopimushinta ja kiinteistön korjaustarpeet puolestaan kuvaavat kiinteistön kassavirran negatiivisen ja positiivisen puolen tärkeimpiä tekijöitä. Kiinteistön kehittymiskyvyllä tarkoitetaan kuinka paljon kehitystoimenpiteillä nähdään saatavan taloudellista hyötyä. Edelle mainittujen kriteereiden attribuuteiksi ehdotettiin makrosijainnille alueellisen BKT:n suhdetta uusiin rakennushankkeisiin, mikrosijainnille keskimääräistä matka-aikaa ja kulkuvälinevaihtoehtoja aluekeskukseen, sopimushinnalle kohteen sopimushintojen neliöillä painotettua keskiarvoa, korjaustarpeille pitkän tähtäimen suunnitelmasta saatavaa korjaustarvearviota ja kiinteistön kehittymiskyvylle asiantuntijan toteuttamaa arviota kiinteistön kehityskelpoisuudesta. Tutkimus ei ottanut kantaa kriteereiden painotukseen tai attribuuttien mittaustulosten pisteyttämiseen, koska työ haluttiin pitää yleisellä tasolla ja edellä mainitut toimenpiteet olisivat vaatineet työn rajaamista koskemaan vain yhtä kiinteistösijoittajaa. Kokonaisuudessaan nähtiin, että yleisen mallin kehittäminen kiinteistöportfoliohallintaan on mahdotonta, johtuen mallissa käytettävien painotusten ja arvofunktioiden yksilöllisestä luonteesta. Tästä johtuen preferenssimallin laadinta olisikin parempi toteuttaa käyttäen vain yhtä kiinteistönomistajaa. Tässä työssä kuvattu prosessi antaa kuitenkin työn kohteena olleille kiinteistönomistajille valmiudet luoda kvantitatiivinen malli oman päätöksenteon tueksi. Prosessin tuloksena saatava malli ehdottaa perustuen kiinteistön sisäsyntyisiin tekijöihin, miten kiinteistöt tulisi lajitella eri salkkuihin. Malli on kuitenkin tarkoitettu vain päätöksentekijän avuksi, ei päätöksentekijäksi
Durbach, Ian N. "Simplified models for multi-criteria decision analysis under uncertainty." Doctoral thesis, University of Cape Town, 2010. http://hdl.handle.net/11427/6394.
Full textIncludes bibliographical references.
When facilitating decisions in which some performance evaluations are uncertain, a decision must be taken about how this uncertainty is to be modelled. This involves, in part, choosing an uncertainty format {a way of representing the possible outcomes that may occur. It seems reasonable to suggest {and is an aim of the thesis to show {that the choice of how uncertain quantities are represented will exert some influence over the decision-making process and the final decision taken. Many models exist for multi-criteria decision analysis (MCDA) under conditions of uncertainty; perhaps the most well-known are those based on multi-attribute utility theory [MAUT, e.g. 147], which uses probability distributions to represent uncertainty. The great strength of MAUT is its axiomatic foundation, but even in its simplest form its practical implementation is formidable, and although there are several practical applications of MAUT reported in the literature [e.g. 39, 270] the number is small relative to its theoretical standing. Practical applications often use simpler decision models to aid decision making under uncertainty, based on uncertainty formats that `simplify' the full probability distributions (e.g. using expected values, variances, quantiles, etc). The aim of this thesis is to identify decision models associated with these `simplified' uncertainty formats and to evaluate the potential usefulness of these models as decision aids for problems involving uncertainty. It is hoped that doing so provides some guidance to practitioners about the types of models that may be used for uncertain decision making. The performance of simplified models is evaluated using three distinct methodological approaches {computer simulation, `laboratory' choice experiments, and real-world applications of decision analysis {in the hope of providing an integrated assessment. Chapter 3 generates a number of hypothetical decision problems by simulation, and within each problem simulates the hypothetical application of MAUT and various simplified decision models. The findings allow one to assess how the simplification of MAUT models might impact results, but do not provide any general conclusions because they are based on hypothetical decision problems and cannot evaluate practical issues like ease-of-use or the ability to generate insight that are critical to good decision aid. Chapter 4 addresses some of these limitations by reporting an experimental study consisting of choice tasks presented to numerate but unfacilitated participants. Tasks involved subjects selecting one from a set of five alternatives with uncertain attribute evaluations, with the format used to represent uncertainty and the number of objectives for the choice varied as part of the experimental design. The study is limited by the focus on descriptive rather than real prescriptive decision making, but has implications for prescriptive decision making practice in that natural tendencies are identified which may need to be overcome in the course of a prescriptive analysis.

Full textksalan August 2006, 88 pages This thesis addresses the problem of ranking multi-criteria alternatives. A Data Envelopment Analysis (DEA)-based approach, the Method of the Area of the Efficiency Score Graph (AES) is proposed. Rather than assessing the alternatives with respect to the fixed original alternative set as done in the existing DEA-based ranking methods, AES considers the change in the efficiency scores of the alternatives while reducing the size of the alternative set. Producing a final score for each alternative that accounts for the progress of its efficiency score, AES favors alternatives that manage to improve quickly and maintain high levels of efficiency. The preferences of the Decision Maker (DM) are incorporated into the analysis in the form of weight restrictions. The utilization of the AES scores of the alternatives in an incremental clustering algorithm is also proposed. The AES Method is applied to rank MBA programs worldwide, sorting of the programs is also performed using their AES scores. Results are compared to another DEA-based ranking method. Keywords: Ranking, data envelopment analysis, weight restrictions.

Full textPlanning is what sustains an energy system. It is a process of analysis and ongoing decision making about what resources and energy technologies to use when supplying energy to society. This research focuses on integrated energy systems, i.e. systems that are comprised of several energy carriers – electricity, gas, hot water - and energy distribution networks. The planning of these kinds of systems is a complex process, influenced by many factors, among which the most important are the availability of energy resources and the competition between different energy carriers in satisfying energy demand. During the last 10-20 years significant changes have taken place on the world energy scene, which have important implications for energy planning. Two main factors have triggered these changes. The first factor is the immediate need to address environmental changes or more generally, to take measures that are sustainable in the long run. Sustainability can be defined in many ways and in relation to different issues such as economic and ecologic development, reduction of greenhouse gases, responsible use of natural resources, social equity, etc. In recent years, an increased awareness of these issues has been observed at all levels of the society. The second factor is the deregulation of national energy sectors in more than 50 countries. This process brought changes in the ownership of different parts of the formerly integrated energy systems. New business opportunities were created in power generation, wholesale power/gas trading and energy retailing, while the energy infrastructures remained state owned or/and under regulatory control. The newly created energy markets (many of them international) have attracted both new players (power, oil and gas companies and financial institutions) together with the old ones (integrated utilities). In parallel with this vertical separation of national energy sectors, recent studies have shown a tendency for horizontal integration at the regional/company level. For instance, in order to reduce their overall business risk, companies prefer to participate in several segments of the energy value chain (in both regulated and non-regulated activities), and often across more than one fuel commodity, such as gas and electricity or district heating. In this context, the competition between different energy carriers in satisfying the end-use energy demand became obvious in economic as well as in technological and environmental terms. Traditionally, in integrated planning, this competition did not play a big role, since the same state entity made decisions at both national and regional levels. However, in the post-deregulation era it is no longer obvious who the planner is. In many cases, planning decision at local levels involve at least three main interest groups: energy companies (and/or other investors), the state and the local community. This thesis is motivated by the need to help planners to cope with the changes in concepts and values concerning the planning of local energy supply systems. This thesis has two aims. The first aim is to improve the understanding of what planning of local systems implies and how such a process can be structured. The second aim is to contribute to the development of decision support methodologies and tools that can cope with the needs in planning. For this purpose, the use of energy modelling and Multi- Criteria Decision Analysis has been studied.

Full textThis work focuses on innovating forest ecosystem management planning and on enhancing its contribution to the provision of ecosystem services. A web-based forest decision support system was developed to support public and private forest managers, involving operational research methods. First, all work related to database management and the integration of data was carried out. Databases were created with PostgreSQL, which on the one hand facilitated the development of multi-criteria linear programs, and on the other met all the data and information needs of a forest decision support system, not only for data processing and information presentation, but also as a source to be consulted and analyzed by forest decision makers. The wSADfLOR, a forest web-based decision support system, integrates one analytic tool to visualize interactive decision maps showing the decision space and trade-offs among the criteria in Pareto frontiers, according to forest users’ management options. Taking advantage of constant improvements in the Interactive Decision Maps tool in wSADfLOR, a second article was developed regarding a web-based approach to show interactive decision maps with Pareto frontiers. Based on these interactive decision maps and jointly with some decision support systems available in the EMDS platform (Criterion DecisionPlus and NetWeaver), a hybrid decision methodology for cases in which there is no consensus among the solutions chosen by different (groups of) forest decision makers was developed, enabling them to choose a unique strategic decision plan

Full textBackground and Motivation
Unlike what is common in Europe and the rest of the world, Norway has traditionally met most of its stationary energy demand (including heating) with electricity, because of abundant access to hydropower. However, after the deregulation of the Norwegian electricity market in the 1990s, the increase in the electricity generation capacity has been less than the load demand increase. This is due to the relatively low electricity prices during the period, together with the fact that Norway’s energy companies no longer have any obligations to meet the load growth. The country’s generation capacity is currently not sufficient to meet demand, and accordingly, Norway is now a net importer of electricity, even in normal hydrological years. The situation has led to an increased focus on alternative energy solutions.
It has been common that different energy infrastructures – such as electricity, district heating and natural gas networks – have been planned and commissioned by independent companies. However, such an organization of the planning means that synergistic effects of a combined energy system to a large extent are neglected. During the last decades, several traditional electricity companies have started to offer alternative energy carriers to their customers. This has led to a need for a more comprehensive and sophisticated energy-planning process, where the various energy infrastructures are planned in a coordinated way. The use of multi-criteria decision analysis (MCDA) appears to be suited for coordinated planning of energy systems with multiple energy carriers. MCDA is a generic term for different methods that help people make decisions according to their preferences in situations characterized by multiple conflicting criteria.
The thesis focuses on two important stages of a multi-criteria planning task:
- The initial structuring and modelling phase
- The decision-making phase
The Initial Structuring and Modelling Phase
It is important to spend sufficient time and resources on the problem definition and structuring, so that all disagreements among the decision-maker(s) (DM(s)) and the analyst regarding the nature of the problem and the desired goals are eliminated. After the problem has been properly identified, the next step of a multi-criteria energy-planning process is the building of an energy system model (impact model). The model is used to calculate the operational attributes necessary for the multi-criteria analysis; in other words, to determine the various alternatives’ performance values for some or all of the criteria being considered. It is important that the model accounts for both the physical characteristics of the energy system components and the complex relationships between the system parameters. However, it is not propitious to choose/build an energy system model with a greater level of detail than needed to achieve the aims of the planning project.
In my PhD research, I have chosen to use the eTransport model as the energy system model. This model is especially designed for planning of local and regional energy systems, where different energy carriers and technologies are considered simultaneously. However, eTransport can currently provide information only about costs and emissions directly connected to the energy system’s operation. Details about the investment plans’ performance on the remaining criteria must be found from other information sources. Guidelines should be identified regarding the extent to which different aspects should be accounted for, and on the ways these impacts can be assessed for each investment plan under consideration. However, it is important to realize that there is not one solution for how to do this that is valid for all kind of local energy-planning problems. It is therefore necessary for the DM(s) and the analyst to discuss these issues before entering the decision-making phase.
The Decision-Making Phase
Two case studies have been undertaken to examine to what extent the use of MCDA is suitable for local energy-planning purposes. In the two case studies, two of the most well-known MCDA methods, the Multi-Attribute Utility Theory (MAUT) and the Analytical Hierarchy Process (AHP), have been tested. Other MCDA methods, such as GP or the outranking methods, could also have been applied. However, I chose to focus on value measurement methods as AHP and MAUT, and have not tested other methods. Accordingly, my research cannot determine if value measurement methods are better suited for energy-planning purposes than GP or outranking methods are.
Although all MCDA methods are constructed to help DMs explore their ‘true values’ – which theoretically should be the same regardless of the method used to elicit them – our experiments showed that different MCDA methods do not necessarily provide the same results. Some of the differences are caused by the two methods’ different ways of asking questions, as well as the DMs’ inability to express clearly their value judgements by using one or both the methods. In particular, the MAUT preference-elicitation procedure was difficult to understand and accept for DMs without previous experience with the utility concept. An additional explanation of the differences is that the external uncertainties included in the problem formulation are better accounted for in MAUT than in AHP. There are also a number of essential weaknesses in the theoretical foundation of the AHP method that may have influenced the results using that method. However, the AHP method seems to be preferred by DMs, because the method is straightforward and easier to use and understand than the relatively complex MAUT method.
It was found that the post-interview process is essential for a good decision outcome. For example, the results from the preference aggregation may indicate that according to the DM’s preferences, a modification of one of the alternatives might be propitious. In such cases, it is important to realize that MCDA is an iterative process. The post-interview process also includes presentation and discussion of results with the DMs. Our experiments showed that the DMs might discover inconsistencies in the results; that the results do not reflect the DM’s actual preferences for some reason; or that the results simply do not feel right. In these cases, it is again essential to return to an earlier phase of the MCDA process and conduct a new analysis where these problems or discrepancies are taken into account.
The results from an MAUT analysis are usually presented to the DMs in the form of expected total utilities given on a scale from zero to one. Expected utilities are convenient for ranking and evaluation of alternatives. However, they do not have any direct physical meaning, which quite obviously is a disadvantage from an application point of view. In order to improve the understanding of the differences between the alternatives, the Equivalent Attribute Technique (EAT) can be applied. EAT was tested in the first of the two case studies. In this case study, the cost criterion was considered important by the DMs, and the utility differences were therefore converted to equivalent cost differences. In the second case study, the preference elicitation interviews showed, quite surprisingly, that cost was not considered among the most important criteria by the DMs, and none of the other attributes were suitable to be used as the equivalent attribute. Therefore, in this case study, the use of EAT could not help the DMs interpreting the differences between the alternatives.
Summarizing
For MCDA to be really useful for actual local energy planning, it is necessary to find/design an MCDA method which: (1) is easy to use and has a transparent logic; (2) presents results in a way easily understandable for the DM; (3) is able to elicit and aggregate the DMs' real preferences; and (4) can handle external uncertainties in a consistent way.

Firstly seven machine types were identified to be included in the study. These machine types include: broach machines, EDM machines, GNG lathes, engine lathes, drilling machines, milling machines and grinders. The information requirements for these machines in terms of attributes for three areas were identified. Functionality, economical and reliability and availability attributes were identified. These attributes were subsequently incorporated into a MS-Access database to provide a database of machine information. Several methods for comparing machines were studied and the decision then fell on one existing method to be used for machine evaluation. A new method was developed to use for evaluating machines. The existing method is the Analytic Hierarchy Process, whereas the new method developed, is called the Quotient Exponential Method. These methods were implemented in the MS-Access database to enable the user to evaluate machines by means of both methods. The results indicate that these methods provide the correct answers according to test values used. It should be noted that the decision methods should, however, only serve as an aid towards an answer and do not necessarily provide the final answer. The AHP process is very time-consuming for this project because of the large number of criteria evaluated.
AFRIKAANSE OPSOMMING: Die doel van hierdie projek is om "n manier te vind om masjiene te evalueer om sodoende "n proses-ketting te optimeer. Eerstens is besluit op die soorte masjiene wat ingesluit gaan word in die projek. Sewe soorte masjiene is gekies en sluit in: RNB draaibanke, masjiendraaibanke, boormasjiene, skuurders, elektriese ontladings masjiene, veelvuldige punt snymasjiene en rubeitelmasj iene. Die inligting-vereistes van die sewe masjiene, in terme van hul attribute vir drie areas, is vervolgens geïdentifiseer. Hierdie drie areas is funksionaliteit, koste, asook beskikbaarheid en betroubaarheid. Hierdie attribute word in "n MS-Access databasis gebruik om "n databasis van masjien-inligting te skep. Verskeie metodes vir die vergelyking en evaluasie van masjiene is bestudeer en daar is op een bestaande metode besluit vir die evaluering van "n aantal masjiene. Daarbenewens is ook "n nuwe metode ontwikkel vir die evaluering van masjiene. Die bestaande metode is die Analitiese Hiërargiese Proses, terwyl die nuwe metode die Kwosiënt Eksponensiële Metode genoem word. Altwee hierdie metodes is in MS-Access geïmplemeteer om die gebruiker in staat te stelom masjiene met albei metodes te vergelyk. Die resultate verkry toon aan dat die korrekte resultaat verkry word volgens die toetsdata wat ingevoer is ten opsigte van die twee metodes. Dit moet in gedagte gehou word dat hierdie metodes egter slegs as "n hulpmiddel tot besluitneming gebruik behoort te word en nie noodwendig die finale antwoord lewer nie. AHP is baie tydsaam gevind, aangesien die masjiene in die projek baie attribute bevat het.

Full textNya tekniska framsteg som ”Hyperloop” som ”femte transportsättet” kan vara ett svar på de problem som drabbar den nuvarande transportbranschen. Hyperloop består av transportbälgen som går genom lågtrycksrör för transport av gods och människor med hög hastighet (upp till 1000 km / tim). Denna teknik kom till framträdande efter att det öppna designkonceptet ”Hyperloop Alpha” publicerades av Musk (2013) och sedan dess har flera regeringar, den akademiska världen och privata företag visat intresse för tekniken med några testspår som byggs i USA och Europa. De första Hyperloop-testningarna för mänskliga passagerare vid 48m / s (173kmph) inuti vakuumröret utfördes framgångsrikt av Virgin Hyperloop i Las Vegas, USA i november 2020 (Mlot, S., 2020). Hardt i samarbete med provinsen Nordholland hade publicerat en konceptstudie om effekterna av 5 föreslagna Hyperloop-rutter i norra Holland (Prov. N-Holland & Hardt, 2020). Detta forskningsprojekt utforskar den föreslagna Hyperloop-transportlösningen i Nordholland och dess närliggande områden ur ett socialt, socioekonomiskt och miljömässigt perspektiv som en jämförelse med befintliga tåg- och flygtransportalternativ. En multikriterieanalys av en av de föreslagna vägarna för Hyperloop-transportprojekt genomfördes som en jämförelse med befintliga järnvägs- och flygalternativ. Resultaten visade att Hyperloop var det högst rankade transportalternativet totalt sett i denna studie, tätt följt av Rail, och Aviation rankades sist. Inom de sociala kriterierna rankades Hyperloop bäst medan inom socioekonomiska och miljömässiga kriterier rankades Rail som det bästa alternativet. Denna MCA kan vara användbar som ett hjälpmedel för beslutsfattare som regionala och nationella regeringar, transportpolitiker eller investerare för liknande Hyperloop-transportprojekt inom Europa.

Full textMassmigration till städer har lett till en enorm ökning av forskning inom hållbarheti stadsmiljöer, dess bedömning och metoder för att förbättra det. Dennaavhandling fokuserar på temat ’multi-criteria decision analysis’ (MCDA, beslutsanalysav flera kriterier) i digital stadsplanering. Den adresserar fråganom hur användbara sådana metoder skulle vara vid kvantitativ bedömning avden miljömässiga hållbarhetspotentialen av stadsområden i planeringsstadiet.Vidare diskuteras potentiella metoder för att ta fram ett poängsystem i miljömässighållbarhet för stadsområden, där den mest lovande väljs och appliceraspå en fallstudie. Detta är meningen att fungera som en konceptvalidering överom appliceringen av MCDA till digital stadsplanering är möjligt och användbart.Metoden utvärderas sedan baserat på dess begränsningar, pålitlighet, robusthettill förändringar i input och med åsikter från experter inom områdenahållbarhet samt digital stadsplanering. Det visas att den föreslagna metoden,en kombination av AHP ochMAUT beslutsanalysmetoderna, har flera fördelarnär det kommer till att skapa representativa hållbarhetspoäng och inkorporeraexpertåsikter, men är svår att skala för att inkludera många kriterier och kräveren stor mängd input. Det föreslås att ytterligare forskning inom detta områdemed mer skalbara MCDA metoder skulle vara lönsamt, samt att öka pålitlighetenoch tillgängligheten av miljödata inom stadsområden skulle vara väldigtanvändbart för detta område.

Full texts long term goal to integrate environmental, social and economic sustainability into the policies, practices and culture of the university and ultimately reduce the consumption of all resources on campus and traffic congestion and accidents. In this context, the consequent cost-benefit effects of the proposed monorail system on campus life were quantified in monetary expressions and the corresponding multi-criteria feasibility assessment including: Break-even Analysis, Cost Effectiveness Assessments and Cost Benefit Analysis have been done successfully. According to these analyses the overall capital cost of system is $46.5 million which covers the 24 months project construction period, and an additional annual operating and maintenance cost of $2 million will span the 30 year project life time. Three different scenarios were proposed for financing the project and relevant break-even points were determined for each of the scenarios. Eventually, it appears that based on the evaluations, constructing such a transit system in METU campus will be cost effective and will certainly enhance the transportation, and will contribute to the institutional improvements and environmental preservation schemes of METU campus.

Interest in road pricing among political leaders, transportation analysts, academics, and government agencies has increased in recent years. There are myriad reasons for this newfound consideration, but the deployment of intelligent transportation systems, the desire for additional revenue sources, and the search for policies that can reduce congestion are among the most important. This thesis examines the impacts of six different types of road pricing strategies, namely: conventional tolling, facility congestion pricing, express lanes (e.g. HOT lanes), area- wide and cordon pricing, network pricing, and distance-based pricing. It also presents a new sketch-planning model, the Road Pricing Decision Analysis Tool (RPDAT), which highlights each strategy's unique set of strengths and weaknesses for achieving different policy objectives and recommends road pricing strategies for particular metropolitan areas. Despite a growing interest in pricing, many decision makers feel unable to estimate the impacts of pricing strategies accurately with conventional models. This thesis discusses the factors believed to be responsible for drivers' choosing to use priced facilities, explains why conventional models are incapable of capturing many of these factors or the aggregate effects of a pricing policy, and identifies some improvements that could be made to existing transportation models. RPDAT performs a multi-criteria analysis of nine road pricing strategies, one of which is a "no pricing" alternative, for a metropolitan area. The user inputs policy priorities and regional characteristics, and RPDAT's algorithms calculate how well each alternative meets the decision maker's criteria as well as index scores that reflect the overall preference for each alternative. This tool is applied to Kuala Lumpur (KL), Malaysia and is used to recommend road pricing strategies for the KL metropolitan area.

Full textBiokol, en solid produkt från termisk omvandling av biomassa med begränsat syre tillgängligt, är identifierad som en möjlig teknik för att minska halten av koldioxid i atmosfären och som jordförbättrare bland andra applikationer. Dess potentiella jordförbättrande egenskaper består av vattenhållning, näringsbindning, balansering av pH-värdet och minskad biotillgänglighet av föroreningar. Däremot så drar inte alla jordar samma nytta av biokolapplikationer. Arbetet syftar till att undersöka lämpligheten av biokolapplikationer på jordbruksmark i Sverige och kommunicera resultaten visuellt med en indikationskarta. En litteraturstudie genomfördes för att analysera jordförbättringsmöjligheterna till följd av biokolsapplikationer. Det fastställdes att kriterierna jordtyp, kväveläckage, markfuktighet, pH och organiskt material var lämpliga för analys i svensk kontext. En multikriterieanalys utfördes i ArcGIS, baserat på rumsliga data för dessa kriterier. Vardera jordbruksblock tilldelades en biokolklass, som varierade mellan hög indikation och ingen indikation. Jordbruksmark ansågs högt rekommenderad för biokolapplikationer om jordtypen var av sandig karaktär och minst ett av kriterierna översteg ett begränsande tröskelvärde. På nationell nivå ockuperade hög indikation för biokolapplikationer 24.2% (528 tusen hektar) av Sveriges jordbruksmark, medan den återstående marken hade antingen måttlig indikation (13%), låg indikation (3.5%) eller ingen indikation (59.3%). Trots rumsliga variationer, hade samtliga svenska län (med datatillgänglighet över 84%) minst 2% åkermark med hög indikation. I synnerhet, 66.1% av Hallands åkermark visade hög indikation. Vidare, Skåne hade den största arealen (148 tusen hektar, 35.7%) med hög indikation för biokolapplikationer. Den motsvarande potentialen för biokol, på nationell nivå, antyder att mellan 0.5 och 26.4 miljoner ton biokol kan appliceras på jordbruksmark med hög indikation för biokolapplikationer, givet appliceringsgrader mellan 1 och 50 ton/hektar över en 20-årsperiod. Detta innebär att svensk jordbruksmark kan rymma en framtida produktion på 500 000 ton per år, förslaget av en statlig utredning, ifall appliceringsgraden förblir under 20 ton/ha. Den utförda multikriterieanalysen inkluderar flertalet subjektiva val och osäkerheter (kriteriakombination, datans noggranhet, tröskelvärden, och klassificeringsmetod). Därmed kan indikationskartorna för biokol ännu inte användas för rekommendationer på jordbruksblocknivå. Resultaten kan emellertid, trots osäkerheter, antyda intressanta storleksordningar på nationell- och länsnivå. Fler svenska fältexperiment samt en mer detaljerad analys behövs. För att kunna ge mer exakta rekommendationer, kan den nuvarande analysen utvecklas genom att koppla samtliga kriterier till fysiska jordbruksmekanismer och biokolsegenskaper och genom att tillämpa rumsliga data av högre upplösning eller till och med fältnivådata. Modeller måste valideras med experimentella data, som hittills är obefintlig: kontrollerade fältförsök med biokol behövs därmed i Sverige.

Full textDagvattenhantering är ett problematiskt område som under de senaste 20 åren har fått allt mer uppmärksamhet då mer föroreningar uppdagats i städerna. Den ökande föroreningen av dagvatten tenderar att orsaka en större risk för djur, människor, ekosystem och recipienter dit dagvatten rinner. På grund av uppmärksamheten som dagvattenhanteringen har fått, har myndigheter, regering och andra intressenter utvecklat dagvatten teknologin ytterligare för att skapa en modern dagvattenstrategi för att handskas med problemet. Dagvattenhantering är nödvändigt eftersom den skapar sociala, miljömässiga och tekniska fördelar samt om dagvattensystemen kombineras med funktionalitet så kan detta ge ökat skydd för ekosystemen samt förbättrad hälsa hos befolkningen i städerna. Den här rapporten beskriver sju olika typer av dagvattensystem så som; rain gardens, dagvattendammar, brunnar, skärmbassänger, svackdiken, rör-/betong magasin samt krossdiken på begäran av Structor Mark Stockholm. Utav dessa 7 dagvattensystem, ingick 3 anläggningar i en så kallad multi-criteria decision analysis (MCDA). Syftet med en MCDA är att utvärdera fyra olika kategorier som kan förknippas med dagvattenhantering. Kategorierna är miljömässiga, sociala, tekniska och ekonomiska. Dessa kategorier utger dock ett brett budskap och för att begränsa analysen så skapades parametrar. Dessa parametrar skapas utifrån varje enskild kategori. För den miljömässiga kategorin skapades parametern grad av rening, för den tekniska kategorin skapades parametern prestanda och underhåll, för den sociala kategorin skapades parametern estetiska och sociala fördelar, och slutligen för den ekonomiska kategorin skapades parametern kostnader och risker. Utifrån dessa parametrar skapades sedan kriterier med specifika huvudämnen som kan bedömas enligt en poängskala från 0-5 där 0 = insignificant, 1=Low, 2= Moderate, 3= Major, 4= High, 5= Very high. Tre dagvattensystem inkluderas i MCDA vilket var; rain gardens, dagvattendammar, krossdiken vars syfte är att rena och fördröja dagvatten. Ett referensalternativ skapades också som ävenkallas ”zero-alternative”, vilket anses inte ha någon rening av dagvatten utan är endast ett transportsystem för dagvatten. Detta referensalternativ kallas drainage by piping. Poängsättningen gjordes av intressenter och invånare i Stockholm. Intressenterna är människor som arbetar med dagvattenhantering antingen på planeringsstadiet eller ute i fält som drift och underhålls personal. Invånare i Stockholm bedömde endast den sociala kategorin eftersom det kan sakna kunskap och insyn i det miljömässiga, tekniska och ekonomiska detaljerna. Totalt kontaktades 20 intressenter där 5 personer valde att medverka i MCDA. Invånare i Stockholm intervjuades på stan, totalt frågades ca 60 personer varav 13 personer valde att medverka i poängsättningen. Poängsättningen av de tre valda dagvattensystemen samt referensalternativet, efter beräkningav medelvärdet samt den totala summeringen resulterade i att dagvattendammar fick den hösta poängen 11,9 hamnade rain garden på andra plats med 11,4, krossdike på tredje plats med 11,3 samt referensalternativet på en fjärde plats med 7,3. De tre dagvattensystemen hade ett relativt liknande slutgiltigt resultat. Dock så skilde sig den individuella kategoriska bedömningen av miljömässiga, tekniska, sociala samt ekonomiska aspekten med större varierande resultat. Även om deltagandet av intressenter var relativt lågt, endast 25 % av det kontaktade intressenterna valde att ställa upp, så anses dessa intressenter vara viktiga för det här projektet då de, utifrån deras kunskap, bedömer det uppsatta kriterierna och det är denna bedömning som resultatet baseras på. Resultaten mellan det olika dagvattenanläggningarna som var inkluderade i MCDA var svåra att särskilja, troligtvis beroende på att ingen viktningsmetod användes. Däremot så är en fördel med MCDA som verktyg i det här fallet, att det gav en indikation på att MCDA kan fungera som ett stödjande verktyg för beslutsfattare även om resultatet i det här fallet var svårt att särskilja. Själva metoden, upplägget och analysen kan användas som medel för att avgöra vilken typ av dagvattenanläggning som passar bäst utifrån de kriterier som är uppsatta. Slutligen så gav intressenterna en påvisning att dagvattenanläggningar ska konstrueras så att hänsyn tas till omkringliggande omständigheter, där varje plats ska ansesvara unik. Det krävs en platsspecifik utredning där hänsyn till geologiska, geotekniska,hydrologiska samt infrastrukturella och miljömässiga aspekter bör utredas innan valet av dagvattensystem bestäms.
