Thesis: S.M. in Technology and Policy, Massachusetts Institute of Technology, School of Engineering, Institute for Data, Systems, and Society, Technology and Policy Program, 2016. Cataloged from PDF version of thesis. Includes bibliographical references (pages 173-176). Volatile commodity prices over the past decade, environmentally-focused policy initiatives and new technology developments have forced manufacturers to consider the idea of substituting towards alternative materials in order meet both consumer and societal needs. The threat of substitution has created the need for manufacturing firms and other members of the supply chain to have the ability to understand the implications of substitution on future product market shares and overall raw material demand. This thesis demonstrates how Multi-Attribute Utility Theory (MAUT) can be extended to the group level to forecast future market shares by applying a distribution to the attribute weights and using a Monte Carlo simulation to capture the choices made by a heterogeneous set of decision makers. Unlike established demand forecasting techniques, such as discrete choice models, this methodology requires only a few data points from a handful of expert interviews and allows for systematic changes of preferences over time. Furthermore, the Monte Carlo MAUT methodology utilizes both revealed preference and stated preference data by integrating the two data types through a response surface methodology. Two case studies on underground distribution and overhead distribution power cables are explored in order to illustrate how the Monte Carlo MAUT methodology can be successfully applied in cases where there are diverse product types, limited numbers of decisions makers and historical market share data is sparse. Each case study illustrates how Monte Carlo MAUT can, on a regional basis, provide key insights into the impacts of changing commodity prices, changing product attribute levels, varying new technology learning rates and changing consumer preferences over time. Furthermore, an example of how Monte Carlo MAUT can be utilized to help policymakers evaluate the advantages, disadvantages and overall impact of different policy schemes within an environmental context is provided. Private firms and public governments alike can utilize Monte Carlo MAUT to improve their understanding of how market shares are likely to change over time, and more importantly, the key decisions needed on each party's behalf in order to maximize societal well-being. by John Stefancik.

Abstract:

In the United States, on-site (in-situ) oil shale extraction methods are underutilized, leading to a potential loss of $20 billion per year in profit. On-site oil shale extraction methods are not considered when discussing large-scale oil shale extraction operations. Off-site (ex-situ) extraction remains the only commercialized method, but on-site extraction is showing considerable promise. The on-site methods allow for the exploitation of deeper oil shale prospects, which have the potential of producing up to 1.32 trillion barrels of oil. Oil shale is an unconventional hydrocarbon resource that must be considered part of the overall energy solution. There are two general methods for extracting oil shale resources: off-site extraction and on-site extraction. The off-site method consists of surface mining and above ground heating. The on-site methods consist of well drilling, well completion, and underground heating. Due to their technical differences, a comparison of the methods is difficult. This praxis seeks to inform the selection of oil shale extraction methods using a multi-attribute utility function as part of a decision tool. The tool consists of three components: the oil production model, the cost model, and the decision model. The practical application of the tool is to bring on-site extraction methods into the conversation. The Piceance Basin, located in western Colorado, is used to show the application of the tool in the field. With the ability to evaluate different extraction methods and process-heating options using the decision tool, the exploitation of more oil shale is possible. Multi-criteria decision-making methods have seen increased use in process industries. Decision making in mining and offshore oil and gas exploration provides useful insights into how decisions are made and how decision analysis could be used for oil shale projects. When evaluating distinct oil shale extraction alternatives, a decision tool, built around multi-attribute utility theory, simulation, and regression analysis provides the best vehicle for systematic decision making.

Abstract:

The Governments' promotion and support of Best Value within the Social Housing Sector has been a prime catalyst in the move by Registered Social Landlord's [RSL's] away from the traditional culture of acceptance of the lowest bid towards consideration of both price and quality criteria as a basis for contractor selection. Manifestly this radical change in the way the sector procures its construction services has forced many of its stakeholders to undergo significant cultural and organisational changes within a relatively short period of time, and problems have developed during this transitional period that have affected the efficiency of the best value process. This research traced the root causes of these problems and its overarching aim was to develop an approach which will enable RSL's and their stakeholders to streamline the best value tender analysis procedure thereby allowing tenders to be dealt with effectively and efficiently whilst also creating a transparent and auditable decision making process. The approach has been established using a mixed methods research methodology utilising; case studies, surveys, rational decision analysis and system evaluation. The main output of the research is the development of a support tool known by the acronym OVID-BV which aids the multi objective decision making process. The underlying rationale for the support tool is based on the innovative use of uncertainty in decision making and the functionality of the tool uses a combination of the analytical hierarchy process (AHP), multi attribute utility theory (MAUT) and whole life costing (WLC).

Abstract:

Reliable infrastructure assets impact significantly on quality of life and provide a stable foundation for economic growth and competitiveness. Decisions about the way assets are managed are of utmost importance in achieving this. Timely renewal of infrastructure assets supports reliability and maximum utilisation of infrastructure and enables business and community to grow and prosper. This research initially examined a framework for asset management decisions and then focused on asset renewal optimisation and renewal engineering optimisation in depth. This study had four primary objectives. The first was to develop a new Asset Management Decision Framework (AMDF) for identifying and classifying asset management decisions. The AMDF was developed by applying multi-criteria decision theory, classical management theory and life cycle management. The AMDF is an original and innovative contribution to asset management in that: · it is the first framework to provide guidance for developing asset management decision criteria based on fundamental business objectives; · it is the first framework to provide a decision context identification and analysis process for asset management decisions; and · it is the only comprehensive listing of asset management decision types developed from first principles. The second objective of this research was to develop a novel multi-attribute Asset Renewal Decision Model (ARDM) that takes account of financial, customer service, health and safety, environmental and socio-economic objectives. The unique feature of this ARDM is that it is the only model to optimise timing of asset renewal with respect to fundamental business objectives. The third objective of this research was to develop a novel Renewal Engineering Decision Model (REDM) that uses multiple criteria to determine the optimal timing for renewal engineering. The unique features of this model are that: · it is a novel extension to existing real options valuation models in that it uses overall utility rather than present value of cash flows to model engineering value; and · it is the only REDM that optimises timing of renewal engineering with respect to fundamental business objectives; The final objective was to develop and validate an Asset Renewal Engineering Philosophy (AREP) consisting of three principles of asset renewal engineering. The principles were validated using a novel application of real options theory. The AREP is the only renewal engineering philosophy in existence. The original contributions of this research are expected to enrich the body of knowledge in asset management through effectively addressing the need for an asset management decision framework, asset renewal and renewal engineering optimisation based on fundamental business objectives and a novel renewal engineering philosophy.

Abstract:

There has been an increasing relevance of the cultural sector in the economic and social development of different countries. However, this sector continues without much input from multi-criteria decision-making (MDCM) techniques and sustainability analysis, which are widely used in other sectors. This paper proposes an MCDM model to assess the sustainability of a musical institution’s program. To define the parameters of the proposed model, qualitative interviews with relevant representatives of Catalan cultural institutions and highly recognized professionals in the sector were performed. The content of the 2015–2016 season of the ‘Palau de la Música Catalana’, a relevant Catalan musical institution located in Barcelona, was used as a case study to empirically test the method. The method allows the calculation of a season value index (SVI), which serves to make more sustainable decisions on musical season programs according to the established criteria. The sensitivity analysis carried out for different scenarios shows the robustness of the method. The research suggests that more complex decision settings, such as MCDM methods that are widely used in other sectors, can be easily applied to the sustainable management of any type of cultural institution. To the best of the authors’ knowledge, this method was never applied to a cultural institution and with real data. Universitat Oberta de Catalunya

Abstract:

In what way does different stakeholders assess a decision and its consequences, and how do these assessments differ? When a company stands before a big decision, they need to consider aspects that are economic, ecologic and social. To make a good decision they need to consider the society and its different stakeholder groups. This study examined how different groups values and weights different criteria. The study has been done with the project Sundsvall logistics park as a case, with criteria related to that project. The goal of the study was to find a way to value and weight different criteria and then compare how the company and the stakeholders assesses these criteria. This has been done through interviews with relevant people that has got extra knowledge about the project Sundsvall logistics park, and through a survey that has been sent out to residents of Sundsvall. The informants and respondents got to assess values and weights to the criteria relative to an indirect alternative where the logistics park isn’t built. The data was then compiled using multi attribute utility theory as a tool to present the comparison. The result of the study suggests that the differences between the valuations and weightings of the criteria is partly due to an uncertainty in how the logistics park would affect the criteria, but that the biggest reason probably depends on what perspective the person is viewing the logistics park from. If the person is viewing the logistics park from an industrial perspective, the criteria related to industrial development is getting more important and is going to take up more room in the analysis. If the person is viewing the logistics park from an individual and social perspective, the criteria related to that is more important and takes up more room in the analysis. På vilket sätt uppskattar olika intressenter ett beslut och dess konsekvenser, och hur skiljer sig dessa uppskattningar åt? När företag idag står inför stora beslut behöver de ta hänsyn till aspekter som är både ekonomiska, ekologiska och sociala. För att beslutet ska bli bra behöver de ta hänsyn till samhället och dess olika intressentgrupper. Denna studie är en undersökning av hur olika grupper värderar och viktar olika kriterier. Studien har utförts mot projektet Sundsvall Logistikpark med kriterier relaterade till projektet. Målet med studien har varit att hitta ett sätt att värdera och vikta olika kriterier för att sedan göra en jämförelse av hur företaget och intressenterna uppskattar dessa kriterier. För att göra detta har intervjuer utförts med personer som är extra insatta i projektet med Sundsvall logistikpark och en enkät skickats ut till boende i Sundsvall. Informanterna och respondenterna har fått uppskatta värden och vikter på kriterierna utifrån ett indirekt alternativ där logistikparken inte byggs. Datan har sedan sammanställts genom att använda multiattributsnyttoteori som verktyg för att presentera jämförelsen. Resultatet av undersökningen tyder på att de skillnader som finns i värderingar och viktningar av kriterierna dels beror på en viss osäkerhet angående hur logistikparken skulle kunna påverka de olika kriterierna och hur ett värde kan uppskattas på dessa, men att den största orsaken troligen beror på vilket perspektiv personen ser logistikparken på. Om personen ser på logistikparken från ett industriellt perspektiv blir kriterier som har med industriell utveckling att göra viktigare och tar större plats i analysen. Om personen ser på logistikparken från ett individuellt och socialt perspektiv blir sådana kriterier viktigare och tar större plats i analysen

Abstract:

Seismic rehabilitation of structural systems is an effective approach for reducing potential seismic losses such as social and economic losses. However, little or no effort has been made to develop a framework for making decisions on seismic rehabilitation of structural systems that systematically incorporates conflicting multiple criteria and uncertainties inherent in the seismic hazard and in the systems themselves. This study develops a decision support framework for seismic rehabilitation of structural systems incorporating uncertainties inherent in both the system and the seismic hazard, and demonstrates its application with detailed examples. The decision support framework developed utilizes the HAZUS method for a quick and extensive estimation of seismic losses associated with structural systems. The decision support framework allows consideration of multiple decision attributes associated with seismic losses, and multiple alternative seismic rehabilitation schemes represented by the objective performance level. Three multi-criteria decision models (MCDM) that are known to be effective for decision problems under uncertainty are employed and their applicability for decision analyses in seismic rehabilitation is investigated. These models are Equivalent Cost Analysis (ECA), Multi-Attribute Utility Theory (MAUT), and Joint Probability Decision Making (JPDM). Guidelines for selection of a MCDM that is appropriate for a given decision problem are provided to establish a flexible decision support system. The resulting decision support framework is applied to a test bed system that consists of six hospitals located in the Memphis, Tennessee, area to demonstrate its capabilities.

Abstract:

We develop a detailed, large-scale, airspace planning and collaborative decision-making model (APCDM), that is part of an $11.5B, 10-year, Federal Aviation Administration (FAA)-sponsored effort to increase U.S. National Airspace (NAS) capacity by 30 percent. Given a set of flights that must be scheduled during some planning horizon, we use a mixed-integer programming formulation to select a set of flight plans from among alternatives subject to flight safety, air traffic control workload, and airline equity constraints. Novel contributions of this research include three-dimensional probabilistic conflict analyses, the derivation of valid inequalities to tighten the conflict safety representation constraints, the development of workload metrics based on average (and its variance from) peak load measures, and the consideration of equity among airline carriers in absorbing the costs related to re-routing, delays, and cancellations. We also propose an improved set of flight plan cost factors for representing system costs and investigating fairness issues by addressing flight dependencies occurring in hubbed operations, as well as market factors such as schedule convenience, reliability, and the timeliness of connections. The APCDM model has potential use for both tactical and strategic applications, such as air traffic control in response to severe weather phenomenon or spacecraft launches, FAA policy evaluation, Homeland Defense contingency planning, and military air campaign planning. The model is tested to consider various airspace restriction scenarios imposed by dynamic severe weather systems and space launch Special Use Airspace (SUA) impositions. The results from this model can also serve to augment the FAAâ s National Playbook of standardized flight profiles in different disruption-prone regions of the National Airspace. Ph. D.

Abstract:

Ces dernières années, la conception de produit vise de plus en plus à remettre le client aucentre du processus de développement. De nouvelles méthodes et outils ont permis de formaliser nonseulement l’identification des besoins et des attentes du client mais également leur transformation enexigences. Cependant, malgré les progrès récemment apparus dans ce domaine, la notion de valeurperçue par le client qui est associée au produit reste faiblement considérée durant le développement duproduit alors que la perception de cette valeur par le client va jouer un rôle clé au moment du choix duproduit.Dans cette thèse, nous proposons une approche normative visant l’intégration de la notion devaleur du produit dans le processus d’établissement des exigences. Un état de l’art présente lesconcepts et les pratiques impliqués dans le déploiement de la fonction de qualité, étroitement liée auprocessus de spécification des exigences basé sur la valeur. Ces concepts sont relatifs aux notionsd’objectifs, de modèles de la valeur, de fonctions d’utilité multi attributs et de hiérarchie et de réseauxd’objectifs.Notre approche se déroule en 4 étapes : (1) identifier et structurer les objectifs à partir del’expression des attentes du client, (2) spécifier les attributs de la valeur perçue par le client etconstruire un modèle de la valeur client, (3) transformer les objectifs en exigences pour construire unmodèle global de la valeur produit et (4) dériver ce modèle global en un modèle de la valeur pourchaque composant du produit. Cette approche permet ainsi de prendre en compte explicitement lavaleur produit perçue par le client en l’intégrant dans les phases de développement, ce qui favorise uneconception proactive dirigée par la valeur.Nous l’illustrons sur un exemple d’avion de ligne développé en Vanguard Studio. Cet exemplea été élaboré par l’ensemble des partenaires au cours du projet Européen IST CRESCENDO et sert decas-test pour ce projet Recently customer-based product development is becoming a popular paradigm. Customer needsand expectations are identified and transformed into requirements in systematic processes for productdesign with the help of various methods and tools. However, in many cases, these approaches fail tofocus on the perceived value that is crucially important when customers make the decision ofpurchasing a product. The requirements specification derived from these approaches are typicallyvalue-implicit.In this thesis, a prescriptive approach to derive value-based requirements specification is proposedby integrating the concept of value into the house of quality of quality function deployment. Anintegrated set of theories, methods and concepts is introduced in order to mitigate the sevenmethodological problems of house of quality regarding to establishing appropriate value-basedrequirements specification. The foundations of the approach include concepts of objective, valuemodel and consequence model, methods of means-ends objectives network, fundamental objectiveshierarchy, response surface methodology and value-driven design, and theory of multi-attribute utilitytheory. The procedure of the approach is a four-step process: (1) identify and structure objectives frominitial customer statements of expectations, (2) specify attributes and construct customer value model,(3) transform fundamental objectives into engineering characteristics to construct system value model,and (4) derive component value models from system value model. Through this procedure, initialcustomer statements can be reasonably derived into customer value model, system value model andcomponent value model. The benefits of the approach are that it enables (1) reasonably qualifying andquantifying customer value, and performing value modeling and simulation, (2) perceived customervalue being subsequently used reactively for design evaluation, and proactively for value-drivendesign.The approach is applied in the context of a European Community’s R&D project CRESCENDO tohelp constructing airlines’ group value model for commercial aircraft development. This applicationfocuses on the first two-steps of the approach, and the value models are implemented in businesssoftware Vanguard Studio

No. of bitstreams: 0 Previous issue date: 2003 Auctions are secular institutions used in the commercial relationships among individuaIs and organizations. They provi de greater flexibility to the processes of determination of prices and allocation of goods, increasing the space for negotiations among buyers and sellers. In the Internet, they have been used, in a growing way, in B2B and G2B electronic commerce, mostly through the model of reverse auctions. However, its unidimensional aspect reduces the negotiations to the variable price, producing, many times, bad results. In the Brazilian case, the Federal Government launched Comprasnet, an Internet public emarketplace, through which public organizations acquire goods and services from registered suppliers. Considering alI the available bidding modalities, 'Electronic Pregão' stands out, as an unidimensional reverse auction, based on price, through which suppliers dispute for contracts of the public administration. In the present work, the author proposes a multicriteria decision-making approach, based on Multi-attribute Utility Theory, as an alternative for the adoption of multi-attribute reverse auctions, adding value to Brazilian Public Buying Organizations.

No entanto, seu aspecto unidimensional reduz as negociações à variável preço, produzindo, muitas vezes, resultados aquém do desejado. No caso brasileiro, o Governo Federal instituiu o Portal Comprasnet, através do qual, as organizações públicas adquirem bens e serviços de fornecedores cadastrados. Dentre as modalidades de licitação disponíveis, destaca-se o Pregão Eletrônico, um mecanismo de leilão eletrônico reverso baseado no atributo preço, através do qual, fornecedores submetem lances decrescentes, na disputa por contratos do setor público. No presente trabalho, o autor propõe uma abordagem de decisão multicritério, baseada na Teoria da Utilidade Multiatributo, como uma alternativa para a adoção de leilões reversos baseados em múltiplos atributos e, consequentemente, para uma maior agregação de valor pelas organizações compradoras do setor público brasileiro.

Seller and buyer had become a indispensable relationship than before, from competition to cooperation, through cooperation with each other to find the adaptive inventory strategies not only reduce the total cost, but increase enterprises competitiveness. However, due to the needs of buyer are gradually expand day by day, a-single supplier is unable to meet buyer’s needs, the buyer would reach a cooperation mechanisms to achieve the purpose of reducing costs with multiple suppliers. However, it would create lots of qualitative factors in the process of cooperation with multiple suppliers, the decision-makers must be consider qualitative factors in many way through some criteria and attributes in supply chain. Therefore, it is momentous for the research to integrate qualitative factors in integrate inventory model. This research applied multi-attribute utility theory to integrate preferences through the metrics and attributes in the buyer, and applied mathematical models to construct a utility function, we can get weights which the buyer assign the adaptive order allocation to all supplier, and add in the integrate inventory model to explore variation in the total cost and the actual orders given the suppliers. Finally, we can understand the variation in inventory through actually data and sensitivity analysis. Therefore, this research expect to construct a comprehensive metric to assign adaptive order's allocation in flexible to all suppliers and provide a decision making model in flexible.

Abstract:

One of the petroleum industry?s goals is to reduce the environmental impact of oil and gas operations in environmentally sensitive areas. To achieve this, a number of Environmentally Friendly Drilling (EFD) technologies have been developed to varying degrees. For example, the use of an elevated platform as an alternative to the gravel pad is less intrusive and leads to a more environmentally friendly approach to drilling operations. Elevated drilling platforms will require the use of piles. Another alternative to the gravel pad is the use of composite mats. Since the demand of low impact technologies for drill site construction has rapidly increased, the parametric study for the feasibility of using pile foundations and composite mats is conducted in this research. Even though a number of EFD technologies have already been developed to varying degrees, few have been integrated into a field demonstrable drilling system (i.e., combination of technologies) compatible with ecologically sensitive areas. In general, it is difficult to select the best combination of EFD technologies for a given site because there are many possible combinations and many different evaluation criteria. The proposed technology evaluation method is based on a systems analysis that can be used for integrating current and new EFD technologies into an optimal EFD system. An optimization scheme is suggested based on a combination of multi-attribute utility theory and exhaustively enumerating all possible technology combinations to provide a quantitative rationale and suggest the best set of systems according to a set of criteria, with the relative importance of the different criteria defined by the decision-maker. In this research, the sensitivity of the optimal solution to the weight factors and the effects of the uncertainty of input scores are also discussed using a case study. An application of the proposed approach is described by conducting a case study in Green Lake at McFaddin, TX. The main purpose of this case study is to test the proposed technology evaluation protocol in a real site and then to refine the protocol. This research describes the results of the case study which provided a more logical and comprehensive approach that maximized the economic and environmental goals of both the landowner and the oil company leaseholder.

Abstract:

碩士 國立清華大學 工業工程與工程管理學系 104 A recent report by the International Diabetes Federation (IDF) indicated that the number of people with diabetes worldwide was anticipated to reach 415 million by 2015. Persons with diabetes must continually monitor their blood glucose levels and manage their diets. A balance between the amount of insulin in a person’s body and the level of carbohydrate intake makes a difference in the blood glucose levels. However, many persons are unable to properly estimate the level of carbohydrates in their food. Moreover, the current apparatus for measuring blood glucose carries the risk of infection if not properly maintained. The purpose of this research is to integrate the Theory of Inventive Problem Solving (TRIZ) and Multi-Attribute Utility Theory (MAUT) to develop a novel technical product for use with diabetic individuals. The proposed methodology was tested and validated with an empirical study using a carbohydrate-detecting device. The innovative device offers a non-invasive and convenient way to provide carbohydrate intake information and to help patients manage their blood glucose levels. The results demonstrate the practical viability of this new approach. This is the first study that integrates TRIZ and MAUT and implements both product and service design using TRIZ. The evaluation of technology feasibility is also considered in this paper.

Abstract:

The lack of safe drinking water worldwide has drawn the attention of decision makers to riverbank filtration (RBF) for its many advantages in purifying surface water. This study provides an overview of the hydrogeologic, fluvial, and environmental influences on the performance of RBF systems and aims to develop a model for RBF site selection. Using multi-attribute utility theory (MAUT), this study structured the RBF siting problem and assessed a multiplicative utility function for the decision maker. In a case study, geostatistical methods were used to acquire the necessary data and geographic information systems (GIS) were used to screen sites suitable for RBF implementation. Those suitable sites were then evaluated and ranked using the multi-attribute utility model. The result showed that sites can be identified as most preferred among the selected suitable sites based on their expected utility values. This study definitively answers the question regarding the capability of MAUT in RBF site selection. Further studies are needed to verify the influences of the attributes on the performance of RBF systems.:Abstract iii Zusammenfassung iv Acknowledgments v Table of Contents vi List of Tables viii List of Figures x Definition of terms xiii 1.

Abstract:

No início dos anos 90, as empresas modificaram a sua forma de encarar a gestão de projetos, deixando esta de ser percecionada como um processo burocrático, passando a ser considerada como uma área de onde se poderia retirar vantagem competitiva para outras áreas, potenciando níveis mais elevados de eficiência, qualidade e valor acrescentado. Dada a importância que a gestão de projetos tem vindo a adquirir, é importante que haja uma monitorização dos projetos, durante a sua implementação, bem como uma avaliação do desempenho tanto dos intervenientes como dos próprios projetos e também uma medição do sucesso dos resultados provenientes da implementação dos projetos. A presente dissertação surge do objetivo do PMI Portugal de promover um concurso, para o ano de 2015, com o objetivo de premiar o Gestor de Projetos do Ano, o Project Management Office (PMO) do Ano e o Projeto do Ano. Para tal, foi necessário que fossem desenvolvidos modelos de avaliação para cada uma das categorias do concurso. Tais modelos foram desenvolvidos com base em dois métodos de apoio à decisão multicritério: o Multi-Attribute Utility Theory (MAUT) e o Analytic Hierarchy Process (AHP). Para o desenvolvimento dos modelos foi necessário definir os critérios de avaliação, as funções utilidade para cada um deles, bem como as respetivas ponderações para a construção da função utilidade global de cada um dos modelos propostos. Por fim, foram conduzidas uma verificação de consistência aos modelos desenvolvidos e uma análise de sensibilidade aos resultados. Em suma, neste trabalho são propostos três modelos de avaliação de desempenho: de Gestores de Projetos, PMOs e Projetos; no final são apresentadas as principais limitações da dissertação e são recomendados trabalhos para o futuro com o intuito melhorar o trabalho desenvolvido.

Abstract:

This thesis describes a framework for a decision support tool which can assist the assessment of options/scenarios for the integrated management of municipal solid waste (MSW) within a local government area (LGA). The framework is applicable to MSW as a whole or to a MSW component. To demonstrate its application, the framework was applied in this thesis to the residential organic waste component including sewage sludge. The work was initially focused on local government (i.e. municipal councils) in the state of Queensland (Australia). However, it is broadly applicable to LGAs anywhere in the developed countries. The goal was to achieve waste management practices which address needs of sustainable society (or briefly: 'sustainable' waste management) by balancing global and regional environmental impacts; social impacts at the local community level; and economic impacts. The framework integrates Life Cycle Assessment (LCA) with other environmental, social and economic tools. For this research, social and economic impacts were assumed to be similar across developed countries of the world. LCA was 'streamlined' to address the researcher's concerns about LCA complexity impeding a practical and operational application of LCA to the evaluation of integrated waste management practices. For this process, 'spatial resolution' was introduced into the LCA process to account for impacts occurring at the local and regional levels - considerations usually neglected by conventional LCA. This was done by considering social impacts on the local community and by use of a regional scaling procedure for LCA data for emissions to the environment which may have impacts at the regional level. The integration followed the structured approach of the Pressure-State-Response (PSR) model suggested by OECD (1993). This PSR model was modified/extended to encompass non-environmental issues and to guide the process of applying multiple tools. For this process, a clear relationship between 'pressure', 'state' and 'response' at the community, regional and global levels was required. The framework primarily focussed on decision analysis and interpretation processes. Multi-Attribute Utility Theory (MAUT) was used to assist with the integration of qualitative and quantitative information. MAUT provides a well-structured approach to information assessment and facilitates objective, transparent decisions. The commercially available decision analysis software package Criterion DecisionPlus 3.0 developed by InfoHarvest Inc (1999) - based on MAUT - was also utilised as the platform for the framework developed in this research. Finally, this thesis describes a case study involving the evaluation of a number of options for integrated organic waste management for a rural LGA in Southeast Queensland. Although refining and testing of the framework was the primary objective of its application to the case study, the case study also provided valuable and interesting results. The results are of use in the development of alternative strategies for managing residential organic wastes. This is specifically important because the integrated management of all organic wastes (including food wastes) has been neglected over many years and most municipal councils are now having to make difficult decisions about alternatives to landfill disposal.
