Full textAbstract:
There is a growing interest in electronic auctions in the literature. Many researchers work on the single attribute version of the problem. Multi-attribute version of the problem is more realistic. However, this brings a substantial difficulty in solving the problem. In order to overcome the computational difficulties, we develop an Evolutionary Algorithm (EA) for the case of multi-attribute multi-item reverse auctions.
We generate the whole Pareto front using the EA. We also develop heuristic procedures to find several good initial solutions and insert those in the initial population of the EA. We test the EA on a number of randomly generated problems and compare the results with the true Pareto optimal front obtained by solving a series of integer programs.
We also develop an exact interactive approach that provides aid both to the buyer and the sellers for a multi-attribute single item multi round reverse auction. The buyer decides on the provisional winner at each round. Then the approach provides support in terms of all attributes to each seller to be competitive in the next round of the auction.

Full textAbstract:
In our daily lives, we often make decisions that require the use of self-control, weighing trade-offs between various attributes: for example, selecting a food based on its health rather than its taste. Previous research suggests that re-weighting attributes may rely on selective attention, associated with decreased neural oscillations over posterior brain regions in the alpha (8-12 Hz) frequency range. Here, we utilized the high temporal resolution and whole-brain coverage of electroencephalography (EEG) to test this hypothesis in data collected from hungry human subjects exercising dietary self-control. Prior analysis of this data has found time-locked neural activity associated with each food’s perceived taste and health properties from approximately 400 to 650 ms after stimulus onset (Harris et al., 2013). We conducted time-frequency analyses to examine the role of alpha-band oscillations in this attribute weighting. Specifically, we predicted that there would be decreased alpha power in posterior electrodes beginning approximately 400 ms after stimulus onset for the presentation of healthy food relative to unhealthy food, reflecting shifts in selective attention. Consistent with this hypothesis, we found a significant decrease in alpha power for presentations of healthy relative to unhealthy foods. As predicted, this effect was most pronounced at posterior occipital and parietal electrodes and was significant from approximately 450 to 700 ms post-stimulus onset. Additionally, we found significant alpha-band decreases in right temporal electrodes during these times. These results extend previous attention research to multi-attribute choice, suggesting that the re-weighting of attributes can be measured neuro-computationally.

Full textAbstract:
Sustainability is increasingly becoming a significant part of strategic asset management worldwide. Road agencies are providing guidelines to assess the relative sustainability of road projects. Unfortunately, environmental features of a road project are still considered as stand-alone evaluations, an added value. Very little has been done to integrate environmental impacts as a part of pavement management systems and other decision support tools to choose between different strategies. In this way, being awarded with a "green" certificate for a specific road project could result in the belief that recognition would correspond to the optimal strategy. Furthermore, a road project awarded with a "green" rating during the construction phase does not mean that the project results "green" if a life cycle approach is considered. Indeed, the most environmental friendly strategies may not be the ones with the highest performance. Using "greener" materials or performing recycle-related practices may lead to a lower performance over the life cycle and therefore produce an increase in maintenance needed, which could in turn result into more congestion due to work zones and higher total emissions. Therefore, construction and maintenance strategies should be analyzed according to three main parameters: cost, performance or effectiveness, and environmental impacts.
The cost analysis part takes into account outflows over the service life of the pavement according to the well-known Life Cycle Cost Analysis methodology. The cheapest maintenance technique over the analysis period was expounded and sensitivity analyses to involved factors were conducted. Performance assessment was developed according to experimental on site data gathered and analyzed over several years to develop deterioration pavement models. Effectiveness of maintenance treatments is further provided and compared to the volume of traffic. In addition, environmental impacts related to maintenance and rehabilitation strategies were analyzed. Emissions were computed over the life cycle of the pavement from the manufacture of raw materials for the initial construction, placement, and maintenance phase. Finally, an optimization procedure was developed for including environmental impacts into a Pavement Management System. A methodology to set a multi-attribute approach system, computing costs, performance, and eco-efficiency over the life cycle of the pavement, is therefore proposed.Ph. D.

This research develops a Fuzzy Multi-Attribute Analysis (FMAA) model to select the most appropriate contractors for Engineering-Procurement-Construction (EPC) projects. It will enable EPC project owners to eliminate the over-reliance on subjective contractor selection and risks associated with incomplete information, imprecise data and vagueness in human decision making. With the combination of fuzzy set theory and multi-attribute analysis, this model addresses the fuzzy nature in human decision making and helps EPC clients achieve the best value of the contract.

Ahmad, Abdul-Rahim. "An Intelligent Expert System for Decision Analysis and Support in Multi-Attribute Layout Optimization." Thesis, University of Waterloo, 2005. http://hdl.handle.net/10012/785.
Full textAbstract:
Layout Decision Analysis and Design is a ubiquitous problem in a variety of work domains that is important from both strategic and operational perspectives. It is largely a complex, vague, difficult, and ill-structured problem that requires intelligent and sophisticated decision analysis and design support. Inadequate information availability, combinatorial complexity, subjective and uncertain preferences, and cognitive biases of decision makers often hamper the procurement of a superior layout configuration. Consequently, it is desirable to develop an intelligent decision support system for layout design that could deal with such challenging issues by providing efficient and effective means of generating, analyzing, enumerating, ranking, and manipulating superior alternative layouts.
We present a research framework and a functional prototype for an interactive Intelligent System for Decision Support and Expert Analysis in Multi-Attribute Layout Optimization (IDEAL) based on soft computing tools. A fundamental issue in layout design is efficient production of superior alternatives through the incorporation of subjective and uncertain design preferences. Consequently, we have developed an efficient and Intelligent Layout Design Generator (ILG) using a generic two-dimensional bin-packing formulation that utilizes multiple preference weights furnished by a fuzzy Preference Inferencing Agent (PIA). The sub-cognitive, intuitive, multi-facet, and dynamic nature of design preferences indicates that an automated Preference Discovery Agent (PDA) could be an important component of such a system. A user-friendly, interactive, and effective User Interface is deemed critical for the success of the system. The effectiveness of the proposed solution paradigm and the implemented prototype is demonstrated through examples and cases.
This research framework and prototype contribute to the field of layout decision analysis and design by enabling explicit representation of experts? knowledge, formal modeling of fuzzy user preferences, and swift generation and manipulation of superior layout alternatives. Such efforts are expected to afford efficient procurement of superior outcomes and to facilitate cognitive, ergonomic, and economic efficiency of layout designers as well as future research in related areas.
Applications of this research are broad ranging including facilities layout design, VLSI circuit layout design, newspaper layout design, cutting and packing, adaptive user interfaces, dynamic memory allocation, multi-processor scheduling, metacomputing, etc.

Ship and submarine design is a very complicated process that requires many trade-offs in design parameters in order to obtain the optimal vehicle effectiveness at the best cost. The number of potential designs is infinite, and the ship designer needs a tool to assist in searching this design space. This thesis uses an evolutionary program to determine the optimal designs of Large Scale Vehicle II, a one-quarter scale submarine model used for propulsor development. A set of designs is randomly generated and represented by binary strings. Each design is treated as an individual in a biological population and evaluated for total ownership cost and two measures of effectiveness. Measures of effectiveness obtained through expert opinion and computer modeling are explored. The designs with high effectiveness and low cost are chosen to produce offspring while the designs with poor effectiveness and high cost are removed from the population. Over many generations, the designs that yield high effectiveness dominate the population. No single design is identified as the optimum. Instead, the information is presented to the decision-maker on a two-dimensional plot that represents the frontier of all non-dominated designs. Each axis represents one of the measures of effectiveness and each level of cost is plotted on a separate curve. This process allows the decision-maker to choose one or several of the non-dominated designs to continue through feasibility and detailed design.

Full textAbstract:
This thesis presents methods to place landing sites for the Urban Air Mobility (UAM) concept. The analysis shows an integrated approach to establish UAM landing site requirements, place landing sites based on predicted demand, and estimate the costs associated with UAM landing sites. This thesis also makes estimates of fares associated with UAM operations. The methods presented are applied to three large urban centers in the United States. The analysis assumes an all-electric, advanced multi-rotor aircraft with autonomous navigational and Vertical Takeoff and Landing (VTOL) capabilities to estimate UAM landing site requirements. The thesis presents the land area requirements of UAM landing sites using Federal Aviation Administration heliport design criteria considering ground-taxi configurations. The analysis performed employs a UAM vehicle with an equivalent Rotor Diameter (RD) of 43 feet. In this thesis, UAM demand is estimated using a mode choice model developed in a companion study (UAM Scenario Analysis).
The methodology to locate UAM landing sites includes splitting and consolidation of UAM landing sites considering the Zillow Transaction and Assessment Dataset (ZTRAX) to introduce land-use size and cost constraints. The sites are split using a K-Means clustering method and are consolidated using a simple center of mass approach where the demand of each landing site is analogous to mass. The results presented in this thesis apply to 75 and 200 landing sites in each region and assume passenger Cost-Per-Mile (CPM) of $1.20 and $1.80, respectively. This thesis presents a comparative study on how the availability of land affects the splitting, consolidation, and relocation of UAM landing sites for each region, the number of landing sites, and the cost per passenger-mile.Master of Science
This thesis aims at the landing sites for the Urban Air Mobility (UAM) concept for commuting passengers in Northern California (17 counties), Southern California (9 counties), and Dallas-Fort Worth (12 counties) region. The aircraft for this service is designed to be an all-electric advanced multi-rotor aircraft with autonomous navigational and Vertical Takeoff and Landing (VTOL) capabilities. The commuting trips considered is focused on passengers traveling to work from home and back. This thesis presents the land area requirements of these landing sites, which are calculated from the Federal Aviation Administration's (FAA) Advisory Circular 150/5390-2C using ground-taxi configuration for a typical representative aircraft of an equivalent rotor diameter (RD) of 43 feet. The landing sites are then split into smaller sites and consolidated into larger sites. This thesis also presents a list of plots of land located within the 0.5 statute-mile boundaries of the landing sites for relocation. This entire analysis is based on the availability of land from the Zillow Transaction and Assessment Dataset (ZTRAX). The results presented in this thesis are for 75 and 200 landing sites set in the study area for a passenger Cost-Per-Mile (CPM) of $1.2 and $1.8, respectively. The results show how the availability of land changes for different CPM for a set of landing sites and affects the splitting, consolidation, and relocation of landing sites for each region. In the end, the thesis presents conclusions and recommendations unique to each region.

Full textAbstract:
Phono Arthrometry is the study of sound naturally generated by a joint in motion, usually associated with the knee. The technique has not achieved use in front line health care, though has received modest attention in the literature since its first appearance in 1902 with a total of 52 publications identified by this thesis. The Phono Arthrometric traces are prone to extreme levels of variability, a difficulty recognised by some of the literature and a plausible reason for the technique not being fully developed. This work seeks to Identify the causes of the intense variability and attempt to account for them using Multi Dimensional Attribute Analysis, a little known data processing technique.

Full textAbstract:
As more and more remotely sensed data becomes available it is becoming increasingly harder to analyse it with the more traditional labour intensive, manual methods. The commonly used techniques, that involve expert evaluation, are widely acknowledged as providing inconsistent results, at best. We need more general techniques that can adapt to a given situation and that incorporate the strengths of the traditional methods, human operators and new technologies. The difficulty in interpreting remotely sensed data is that often only a small amount of data is available for classification. It can be noisy, incomplete or contain irrelevant information. Given that the training data may be limited we demonstrate a variety of techniques for highlighting information in the available data and how to select the most relevant information for a given classification task. We show that more consistent results between the training data and an entire image can be obtained, and how misclassification errors can be reduced. Specifically, a new technique for attribute selection in neural networks is demonstrated. Machine learning techniques, in particular, provide us with a means of automating classification using training data from a variety of data sources, including remotely sensed data and expert knowledge. A classification framework is presented in this thesis that can be used with any classifier and any available data. While this was developed in the context of vegetation mapping from remotely sensed data using machine learning classifiers, it is a general technique that can be applied to any domain. The emphasis of the applicability for this framework being domains that have inadequate training data available.

Full textAbstract:
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).

Full textAbstract:
Water heating in the United States has the largest energy consumption of any residential related use. It uses more energy than all other home appliances combined. They have also been implicated as the source of waterborne disease outbreaks. With such high stakes, it is recommended that a Decision Support Tool (DST) be used prior to selection of a water heater for new construction or replacement. Although there are numerous tools available, it is challenging to find a tool that takes into account all factors critical to the selection of water heaters, addresses gaps and barriers, provides adequate information to all stakeholders and finally, assists in rational decision making towards more sustainable choices.
The purpose of this research is threefold: (a) to inventory, organize and characterize web-based existing water heater Decision Support Tools (eDSTs) to highlight gaps and/or shortcomings; (b) to develop a Decision Support Tool Skeleton (DSTS) containing a comprehensive list of sustainability capital, criteria and indicators based on Multi-Attribute Decision Making (MADM) approach; (c) to create a stakeholder map comprising supply chain, stakeholder system, decision making process during water heater selections as well as other market factors, using metasynthesis of collected documents.
The findings of this research indicate that considerable gaps and shortcomings exist in the current pool of water heater DSTs. To address these barriers, information was captured from various documents in a process of qualitative data analysis called coding. The coding process generated attributes which were used to generate a comprehensive set of capital, criteria, subcriteria and indicators using MADM approach. This organizing structure developed on lines of sustainability assessment will serve as a starting point towards achieving global sustainability in real life. Importantly, information asymmetry between various stakeholders is evidence of the fact that the existing tools are not addressed in an equitable manner. This study will help determine the stakeholder system and the decision making process for selection of water heaters in the residential sector, so as to effectively implement new tools being created.Master of Science

Full textAbstract:
Nuclear energy is a source of carbon free power. With many countries striving to make deep carbon cuts in their energy sectors, nuclear energy could be a large part of the solution. One of the main obstacles standing in the way of the use of nuclear energy is the issue of used nuclear fuel disposal. According to the NEI, the U.S. creates about 2000 metric tons of used nuclear fuel per year and has generated around 76,000 metric tons of used nuclear fuel over the last 4 decades. While there are technical problems that need to be solved, it is primarily the public and political opposition to the disposal of used nuclear fuel that stands in the way of progress in this area. This work addresses this issue through Multi-Criteria Decision Analysis (MCDA). To make a decision among ten different fuel cycles, we have brought together five stakeholders: Nuclear Scientists and Engineers, Environmental Scientists, Economists, Political Scientists, and The General Public. Using Multi-Attribute Value Theory (MAVT), we have been able to develop decision models for each stakeholder as well as a model that combines them all and came to the conclusion that of the ten fuel cycles considered, the best decision is to continue to use On Site Dry Cask Storage. This decision is made with small sample sizes but the methodology could be applied at much larger scales and can potentially be used to choose a fuel cycle that encounters much less political and social opposition to its implementation.

Full textAbstract:
The purpose of this study was to develop a decision model for early-stage breast cancer patients. This model provides an opportunity for comparing two main treatment options, mastectomy and lumpectomy, with respect to quality of life by making use of Decision Theoretic Techniques.
A Markov chain was constructed to project the clinical history of breast carcinoma following surgery. Then, health states used in the model were characterized by transition probabilities and utilities for quality of life. A Multi Attribute Utility Model was developed for outcome evaluation. This study was performed on the sample population of female university students, and utilities were elicited from these healthy volunteers. The results yielded by Multi Attribute Utility Model were validated by using Von Neumann-Morgenstern Standard Gamble technique. Finally, Monte Carlo Simulation was utilized in Treeage-Pro 2006 Suit software program in order to solve model and calculate expected utility value generated by each treatment option. The results showed that lumpectomy is more favorable for people who participated in this study. Sensitivity analysis on transition probabilities to local recurrence and salvaged states was performed and two threshold values were observed. Additionally, sensitivity analysis on utilities showed that the model was more sensitive to no evidence of disease statehowever, was not sensitive to utilities of local recurrence and salvaged states.

Full textAbstract:
A group key exchange (GKE) protocol allows a set of parties to agree upon a common secret session key over a public network. In this thesis, we focus on designing efficient GKE protocols using public key techniques and appropriately revising security models for GKE protocols. For the purpose of modelling and analysing the security of GKE protocols we apply the widely accepted computational complexity approach. The contributions of the thesis to the area of GKE protocols are manifold. We propose the first GKE protocol that requires only one round of communication and is proven secure in the standard model. Our protocol is generically constructed from a key encapsulation mechanism (KEM). We also suggest an efficient KEM from the literature, which satisfies the underlying security notion, to instantiate the generic protocol. We then concentrate on enhancing the security of one-round GKE protocols. A new model of security for forward secure GKE protocols is introduced and a generic one-round GKE protocol with forward security is then presented. The security of this protocol is also proven in the standard model. We also propose an efficient forward secure encryption scheme that can be used to instantiate the generic GKE protocol. Our next contributions are to the security models of GKE protocols. We observe that the analysis of GKE protocols has not been as extensive as that of two-party key exchange protocols. Particularly, the security attribute of key compromise impersonation (KCI) resilience has so far been ignored for GKE protocols. We model the security of GKE protocols addressing KCI attacks by both outsider and insider adversaries. We then show that a few existing protocols are not secure against KCI attacks. A new proof of security for an existing GKE protocol is given under the revised model assuming random oracles. Subsequently, we treat the security of GKE protocols in the universal composability (UC) framework. We present a new UC ideal functionality for GKE protocols capturing the security attribute of contributiveness. An existing protocol with minor revisions is then shown to realize our functionality in the random oracle model. Finally, we explore the possibility of constructing GKE protocols in the attribute-based setting. We introduce the concept of attribute-based group key exchange (AB-GKE). A security model for AB-GKE and a one-round AB-GKE protocol satisfying our security notion are presented. The protocol is generically constructed from a new cryptographic primitive called encapsulation policy attribute-based KEM (EP-AB-KEM), which we introduce in this thesis. We also present a new EP-AB-KEM with a proof of security assuming generic groups and random oracles. The EP-AB-KEM can be used to instantiate our generic AB-GKE protocol.

Full textAbstract:
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.

Previous issue date: 2003Auctions 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.

Na Internet, têm sido empregados, de maneira crescente, em atividades de comércio eletrônico B2B e G2B, em sua maioria, através da modalidade de leilão reverso. 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.

Full textAbstract:
The past decades have seen the state of the art in aerospace system design progress from a scope of simple optimization to one including robustness, with the objective of permitting a single system to perform well even in off-nominal future environments. Integrating flexibility, or the capability to easily modify a system after it has been fielded in response to changing environments, into system design represents a further step forward. One challenge in accomplishing this rests in that the decision-maker must consider not only the present system design decision, but also sequential future design and operation decisions. Despite extensive interest in the topic, the state of the art in designing flexibility into aerospace systems, and particularly space systems, tends to be limited to analyses that are qualitative, deterministic, single-objective, and/or limited to consider a single future time period.
To address these gaps, this thesis develops a stochastic, multi-objective, and multi-period framework for integrating flexibility into space system design decisions. Central to the framework are five steps. First, system configuration options are identified and costs of switching from one configuration to another are compiled into a cost transition matrix. Second, probabilities that demand on the system will transition from one mission to another are compiled into a mission demand Markov chain. Third, one performance matrix for each design objective is populated to describe how well the identified system configurations perform in each of the identified mission demand environments. The fourth step employs multi-period decision analysis techniques, including Markov decision processes (MDPs) from the field of operations research, to find efficient paths and policies a decision-maker may follow. The final step examines the implications of these paths and policies for the primary goal of informing initial system selection.
Overall, this thesis unifies state-centric concepts of flexibility from economics and engineering literature with sequential decision-making techniques from operations research. The end objective of this thesis' framework and its supporting analytic and computational tools is to enable selection of the next-generation space systems today, tailored to decision-maker budget and performance preferences, that will be best able to adapt and perform in a future of changing environments and requirements. Following extensive theoretical development, the framework and its steps are applied to space system planning problems of (1) DARPA-motivated multiple- or distributed-payload satellite selection and (2) NASA human space exploration architecture selection.

No abstractCoastal and marine ecosystems are some of the most heavily exploited with increasing degradation. This alarming situation appeals for urgent and effective actions. The optimal balance between use and conservation of ecosystems theoretically requires all costs and benefits to be considered in decision-making, including intangible costs and benefits such as non-market use and non-use values. The broad aim of this PhD is to examine how these economic values associated with coastal and marine ecosystem services can be measured, and how the economic valuation exercise may be considered and influence management decision- making.The first analytical part of the thesis focuses on assessing non-market use and non-use values, through econometric methods. The characterization and estimation of non-use values are complex and controversial, especially when the valuation exercise is focusing on individuals who are users of the ecosystem services being considered. An original approach based on a stated preference method, namely choice experiments, is developed then empirically applied in quantifying non-market values for marine and coastal ecosystems in two areas in New Caledonia. It allows the estimation of non-use values for populations of users in an implicit way. An in-depth analysis of the individuals’ choice heuristics during the valuation exercise is also conducted, with a focus on payment non-attendance. This issue is dealt with by comparing multiple modelling approaches in terms of: (1) inferred attendance, in relation to stated attendance; (2) attendance distribution according to several socio-economic variables; and (3) welfare estimates.After noting that the potential influence of economic valuation in decision making is unclear and largely unexplored in the literature, the second major component of this PhD aims to examine if, how and to what extent the economic valuation of ecosystem services, including measures of non-market values, influence decision-making regarding coastal and marine ecosystems management in Australia. Based on two nation-wide surveys, the perceived usefulness of the economic valuation of ecosystem services by the general public and decision-makers is studied, and the reasons why decision-makers may or may not fully consider economic values are elicited. Using a multi-criteria analysis, a part of the surveys also aims at examining the relative importance of different evaluation criteria (ecological, social and economic) when assessing the consequences of a hypothetical coastal development project on commercial activities, recreational activities and marine biodiversity

"Stochastic Multi Attribute Analysis for Comparative Life Cycle Assessment." Doctoral diss., 2015. http://hdl.handle.net/2286/R.I.29688.
Full textAbstract:
abstract: Comparative life cycle assessment (LCA) evaluates the relative performance of multiple products, services, or technologies with the purpose of selecting the least impactful alternative. Nevertheless, characterized results are seldom conclusive. When one alternative performs best in some aspects, it may also performs worse in others. These tradeoffs among different impact categories make it difficult to identify environmentally preferable alternatives. To help reconcile this dilemma, LCA analysts have the option to apply normalization and weighting to generate comparisons based upon a single score. However, these approaches can be misleading because they suffer from problems of reference dataset incompletion, linear and fully compensatory aggregation, masking of salient tradeoffs, weight insensitivity and difficulties incorporating uncertainty in performance assessment and weights. Consequently, most LCA studies truncate impacts assessment at characterization, which leaves decision-makers to confront highly uncertain multi-criteria problems without the aid of analytic guideposts. This study introduces Stochastic Multi attribute Analysis (SMAA), a novel approach to normalization and weighting of characterized life-cycle inventory data for use in comparative Life Cycle Assessment (LCA). The proposed method avoids the bias introduced by external normalization references, and is capable of exploring high uncertainty in both the input parameters and weights.Dissertation/Thesis

information on preferences of restaurateurs, retailers, and
wholesalers for whole albacore, low-value added albacore
products (chunks, medallions, and steaks), albacore loins,
and high-value added albacore products (hot smoked and lox).
All of these products were categorized as non-traditional
market forms of albacore products, except whole albacore.
The empirical analysis was based on self explicated and
conjoint analysis. The demand models for albacore products
were estimated using weighted least squares. Profitability
equations for albacore products were estimated using a two-limit Tobit model. From the self explicated section, it was
found that the attributes of price, flavor, blood
spots/bruising, and bleeding of whole albacore were
considered highly important by respondents. From the
conjoint analysis section, it was found that, as expected a
priori, price had a statistical significant effect on the
demand and profitability models for all albacore products.
Other variables, such as location of the firm, type of firm,
experience with tuna species, and ranking of albacore had
statistical significant effects on the demand and
profitability equations. Wholesalers, restaurateurs, and
retailers agreed that quality is a major concern and will
influence their preferences when purchasing albacore

Background: Epidural analgesia (EA) is an effective and safe method to relieve labor pain. Although the prevalence of epidural labor analgesia has been increasing in most countries, it is still infrequently in Taiwan compared with most west countries. Most studies in relation to labor EA focused on its benefits and drawbacks. Little is known about the factors associated with decision on EA. In order to propagate the labor EA, the elucidation of decisive factors related to labor EA is of paramount importance. Aims: We applied multi-attribute utility (MAU) theory to ascertain possible factors on which we based to predict whether parturients would receive EA or not during their labor. Materials and methods: A cross-sectional survey was therefore conducted by enrolling all parturients with spontaneous delivery or non-elective cesarean section in Taipei Veterans General Hospital from Jan 18 2006 to Apr 8 2006. A hierarchical questionnaire based on MAU theory was designed by experts to include individual attributes, knowledge and attitude toward EA and cue factors. The experts also performed the weighting process and calculated the scores in different levels according to the MAU theory. The behaviors of parturients were also predicted by the application of MAU model. Sensitivity, specificity, and receiver operating characteristics (ROC) curve by different cut-off points were also evaluated to assess predictive validity of the MAU model. Result: There were 205 parturients recruited in our study. Among them, 167 parturients, consisting of 84 and 83 parturients in the EA and non-EA group, returned the questionnaire, respectively. Of 167, 151 subjects completed all questions. The only differences of individual attributes between the two groups are the parity and education level. More parturients have bachelor degree or above in the EA group compared with the non-EA group (85.7% vs. 66.3%, p=0.003). Besides, there are also more primipara in the EA group (76.2% vs. 47.0%, p<0.001). For items in MAU model, 12 of 20 items revealed significant differences between the two groups. Among these items, “Fear to side effects”, “Fear to severe complications” and “Fear to needle” had the most significant differences. Among the 10 sub-concepts, only 7 of them had significant differences. All sub-concepts under two concepts of “benefit” and “barrier” showed significant differences. In contrast, only 1 sub-concept in “cue to action” concept had significant difference. All 3rd level concepts showed significant differences between the two groups (all p<0.001) and the final decision also showed significant differences. The mean difference in final MAU score between the two groups was 0.38 (p<0.001). The best cut-off point of our model was 0.2 and the sensitivity and the specificity of pre-labor decision were 0.84 and 0.79, respectively. The sensitivity and specificity of final decision were 0.84 and 0.72. The area under ROC was 0.91 (0.86-0.96) for pre-labor decision and 0.83 (0.76-0.89) for final decision. Conclusion: The most influential individual attributes related to labor EA were parity and education level. MAU model can be used to evaluate the relative importance of items associated with knowledge and attitude toward EA and cue factors. Our MAU model can predict pre-labor decision and final decision.

With the rapidly advances of technology, Smartphone has become a necessity in the modern life. Due to the phenomenon of low fertility and the improvement of medical treatment, the aged population must to be increased. In other words, the demands of senior toward Smartphone will increase too. The aim of this study is to analyze the senior''s demands of Smartphone. This study hopes to find a new group of consumer for the phone market which is invariably to compete in function and technology, and to provide a reference for enterprises. In order to understanding the demands of senior toward Smartphone, we use the consumers'' viewpoint through the three stages of questionnaires to interview the consumer of seniors. After finding out the criterion which the consumer value, this study uses a hybrid Multiple Attributes Decision Making (MADM) model which combines Decision Making Trial and Evaluation Laboratory (DEMATEL) and Analytic Network Process (ANP) to derive DEMATEL-based ANP (DANP) which can obtain the correlation and weights between the criteria. Finally, a case study is provided by using Gray Relational to compare the performance at each criterion on current market share rate of the top three Smartphone manufacturers. The empirical example illustrates the feasibility and effectiveness of the proposed method. The results show that "image of the brand", "after-sales service", "size of the display", "solidity" are the most important criteria for seniors consumers. This study provides some improvements for the three Smartphone manufacturers to meet the needs of senior citizens.

In order to get higher return on investment, real estate investment projects might be executed immediately or deferred after the construction company acquires the land. However, the two development strategies will generate development schemes which are combined by different expected benefits and investment risks due to different planning and deferred time limit. That’s why it’s difficult to make the best decision. Therefore, this study uses the concepts of Multi Attribute Utility Theory and Efficient Frontier to create a Multi Attribute Utility Analysis model. This model can consider both expected benefits and investment risks to reasonably measure the multi attribute utility value for decision makers. In addition, the model analyzes the most investable development scheme from Efficient Frontier concept and the investors’ risk preference. By using the model, the decision quality of investment project could be better. Finally, this study combines Multi Attribute Utility Analysis model and Real Estate Investment Benefit and Risk Evaluation model to build a computer analyzing system(PDS). By applying PDS system decision makers can compare different development schemes by Trade-off analysis to choose the best development project. Additionally, by case study, this model could sieves the best investment project and make decision makers clearly understand the meaning of analyzed results.

The purpose of this study is to evaluate the performance of mutual funds. "Treynor Ratio", "Sharpe Ratio", "Jensen''s Alpha" and "Information Ratio" are four commonly used indices for evaluating the competing mutual funds. However, it is not clear which measure is the most robust. This study has a different focus not only on investigating the four criteria separately but also combining all the indices at the same time in making a final ranking of the mutual funds. This study found that Jensen''s Alpha outperforms the rest indices of both uni-criterion and multi-criteria. Although multi-criteria indices are not noticeably better than uni-criteria indices, the index using CRITIC weight method under City block distance measure is recommended if the correlation between the rankings is concerned. Even though the new indices are not noticeably more accurate than uni-criterion indices in ranking the mutual funds. But a good and informative index should be able to chart aggregate changes in market levels. Those uni-criterion indices only justify the risk or a mutual fund manager''s ability partially. Multi-criteria indices are another choices which can be used to evaluate the mutual funds and can take all the criteria into consideration simultaneously. That''s the main contribution of this research.

The condensation process is one of the most used methods in the chemical reaction which takes an important rule in the petrifaction industry. There usually are several quality characteristics in the condensation processes. The optimization of parameter is a very important and complicate work in the condensation processes. In this research, Taguchi method is applied to find the optimal level of parameters (temperature, pressure, freezing water quantity, process backflow quantity)in condensation process for water purity content and the heavy quantity individually. The grey relational method is used to obtain the synthetic index of combined index for two quality characteristics. Then, the synthetic index is analyzed by ANOVA to find the best level combinations of factors for two quality characteristics altogether. The results showed that the best level for each parameter are the freezing water quantity controlled 52.0(ton), the temperature of condensation 13.0 (C), the process backflow quantity 20.0(ton/hr), the pressure of condensation 0.70(kg/cm). By using the best level for each parameter, the objective of reducing water content and the heavy quantity are achieved.

Huge amounts of information is sent to all kinds of network platforms, and the spread of the Internet from the traditional site operators into users. Online customer reviews are helping manufactures to decide marketing strategies, and consumers used to watch online reviews before they buy products. However, the network information is complex. Consumers search keywords in the use of evaluations that from a large number of links in the page one by one, and then read the article carefully to find out the comments, which is a lengthy process for the consumer. This study present a prototype which automated collect and classify consumer reviews based on multi-attribute products. Through the topic model and sentiment analysis, consumers can quickly extract the results and the product evaluation that do not need to read the entire content. In this study, 2837 reviews were collected from PTT. Through the topic analysis of LDA to build feature lexicon, the reviews would be automatically classified into marketing and non-marketing category, and then the sentiment polarity would be analyzed by marketing 4C category. Experiment result showed that classified as marketing 4C category the average of accuracy was 93.84% and the average of F1-Measure was 93.08%. For the category of sentiment polarity of consumer reviews the average accuracy was 91.74% and F1-Measure was 90.68%. It was proved that the sentiment polarity of this machine classification has good accuracy, so that consumers have reliable and correct reference when searching for articles without having to spend too much time browsing the contents of the article.

Under a series of Manpower Trim policies in recent years, national resources should be allocated and used more effectively and efficiently in the Ministry of National Defense. In addition, the authority should consider whether the budgetary and financial units, which take charge of military financial prediction, budget execution, and time control, could bear the heavy workload. This research leads to the Multi-Attribute Decision Making (MADM) from UNISON Decision Analysis Framework, analyze the topic for study and construct an analytical model of national defense budget executing embedded the Analytic Hierarchy Process (AHP) and the Simple Multi-Attribute Ranking Technique (SMART) to explore the effects of budget performance and work results in military, and to analyze whether the manpower of budgetary unit can bear the workload, in order to set the criteria to plan the deployment of the future manpower in budgetary units. According to taking budget implement rate, the number of expense, and the amount of money as the factors, and then the headings and purpose as the sub-factors, the results are represented as the overall loading score. In 93.38% of the military units, the score is between 0.50-0.69. The result is highly centralized and the work is allocated equally. In addition, the work loading from 2006 to 2008 were decreased gradually. Therefore, it suggested that the authority could regulate the manpower timely in the basic level, add more budget in financial planning and in statistical analysis experts training, in order to raise the effectiveness of national defense budget continuously.

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.

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.
