Turkish Compulsory Earthquake Insurance (ZDS) introduced after the 1999 Earthquakes aimed to lower financial burdens of the State and to promote safer building construction. High earthquake risk in Turkey necessitates risk mitigation, in line with the priority of the new international policy. Yet, the ZDS system operates without regard to risk mitigation, and it is far from being a compulsory condition. The ZDS system has low penetration ratios due to expectations of State-aid in the event of a disaster, which arise from perceived attributes of ZDS, according to the findings of the Zeytinburnu household survey. The ZDS system generates social inequalities because purchase of the ZDS contracts is voluntary. This is related to higher social statuses and general insurance purchase behavior, whereas insured homeowners in middle-lower income levels are observed to differ significantly from un-insured homeowners in their perception of the ZDS purchase as &lsquo / compulsory&rsquo / and as a form of &lsquo / social solidarity&rsquo / . Operation of the ZDS disregarding risk mitigation seems to promote fatalistic attitudes andTurkish Compulsory Earthquake Insurance (ZDS) introduced after the 1999 Earthquakes aimed to lower financial burdens of the State and to promote safer building construction.

Operation of the ZDS disregarding risk mitigation seems to promote fatalistic attitudes and reluctance to conform with requirements of risk mitigation. Low penetration ratio and high earthquake risk threaten efficiency of the ZDS system and does not reduce burdens of the State. Based on survey findings, a more appropriate strategy for the achievement of resilience against earthquakes could be possible through the collaboration of the ZDS system with local administrations. It is observed that by means of a &lsquo / Grant Program&rsquo / , there may be abundant reason and evidence to achieve convertion of the ZDS system from a post-disaster loss compensation mechanism to a predisaster risk reduction benefactor. Supporting municipalities to produce urban risk maps could reduce risks by more accurate estimation of potential losses, and an extended coverage of the ZDS system to urban risks. Relationship analyses between homeowners&rsquo / attributes, perceptions and tendencies toward alternative policies indicate the necessity of introducing policies based risk-rated premiums. Homeowners are observed as requiring technical and financial assistance to take mitigation measures, decisions under individualized conditions, on the other hand, seem to reinforce fatalistic attitudes and reluctance due to the disregard of risk mitigation benefits and ZDS purchase. Waste of public resources and creation of social inequalities could be prevented by enhancing the capacities of local authorities to implement urban risk mitigation plans and community-based projects via a Grant Program. &lsquo / Relationship analyses&rsquo / of the attitudes of homeowners for alternative policies with respect to their attributes and perceptions revealed that a Grant Program could result in the perception of the ZDS system as a form of social solidarity in risk mitigation. This is to reduce fatalistic attitudes, and curb reluctance compared to individualized conditions of insurance purchase. As a result, willingness to mitigate risks through active participation and purchase of ZDS contracts, particularly among homeowners in the middle-lower socio-economic statuses are likely to expand leading to a resilience society.

隨著經濟成長，高度競爭的生活環境造成人們睡眠品質不佳或失眠，多半是深受入睡困難、淺眠和早醒等困擾。因此，對於現代人逐漸願意投資在寢具和床墊產品只求一夜好眠。 床墊是為耐久財，生命週期長且消費者感知風險高，因此大多消費者在購買前會先進行相關資訊蒐集。網路的普及使得商品資訊在網路上公開，使得網路成為消費者購物前蒐集資訊的主要管道。而隨著web2.0的興起，消費者在網路上分享產品資訊的網路口碑有了爆炸性的增加，產生了讓廠商無法忽視的網路口碑效應。透過網路口碑的分析可以了解消費者與市場需求，提供廠商未來修正整體經營策略。 本研究透過網路蒐集網路口碑進行內容分析法，瞭解消費者選購床墊的決策流程以及對國內外高價品牌床墊的評價。從研究結果可以發現，近四成的消費者是為了改善睡眠品質而產生購買床墊的需求。實體通路及網路是消費者主要蒐集資訊的管道。在評估床墊時，消費者重視床墊品質、價格以及軟硬度，他們在意床墊和彈簧的設計以及床墊軟硬度。而有近五成五的消費者是偏好較硬床墊。近九成九的購買管道為品牌床墊專賣店和一般床墊經銷通路居多。約1%的消費者由於網路購物的七天鑑賞期而選擇在網路購物平台購買。近七成五的消費者購買後表示滿意，近二成五的消費者購後仍不滿意床墊與彈簧的設計與材質，以及依舊腰酸背痛等。 消費者對於國內外床墊品牌的正面口碑多於負面口碑，其中消費者對席伊麗品牌形象最佳，負面評論少。而消費者對本土床墊品牌，如：德泰彈簧床、老K牌彈簧床和10 Days的品質也有正面的評價，但對於品牌形象與經營則保持負面的態度，建議未來應針對加強品牌權益的目標，調整行銷策略。 / With economic growth, a highly competitive environment results people in poor quality sleep or insomnia. Most of them suffer from difficulty in falling asleep, light sleep and wake early. Therefore, people are more and more willing to invest in bedding, pillow and matress just for a good quality sleep. Due to the mattresses are durable goods with long product life cycle and perceived risk, consumers usually spend a lot of time to study the mattresses before purchasing. On the other hand, with the universal of the Internet and the growth of web2.0, the blooming e word-of-mouths (eWOM) makes consumer tend to uderstand products in advance by reading comments. That indeed cause a serious effect on eWOM for firms who should not ignore. Through analyzing the eWOM, firms could understand the trend on the demand side then modify their strategies. This study collected eWOM from the Internet and use content analysis to understand consumer purchase decision process as well as the consumers’ insights into upscale mattresses. From the results, we could know that almost 40% of consumers buy a new mattress for improving sleeping quality. They usually collect the necessary information by visiting physical channels and surfing on the Internet. They evaluate the mattresses quality, price, softness and firmness. They care about mattresses and springs’ design and matieral. Almost 55% of consumers prefer to buy a firm mattress. Almost 99% of consumers buy mattresses at the physical channels. Rest of consumers buy mattresses on e-commerce due to the 7-days return warranty. Almost 75% of consumers feel satisfied after purchasing. Rest of them are not satisfied at the mattresses and springs’ design and material and uncomfortableness. Consumers gave more positive comments than negative comments on the selected mattresses brands. Sealy had a reputation on its brand image and quality; King Koil, The-Tai Mattress, Kingbed, Tempur and 10 Days are all well-know for their quality as well, but still had some negative comments on the brand image and price. After the eWOM studies on each selected brand, this study gave suggestions to each brand for its future marketing strategy.

The motion planning problem can be formulated as a Markov decision process (MDP), if the uncertainties in the robot motion and environments can be modeled probabilistically. The complexity of solving these MDPs grow exponentially as the dimension of the problem increases and hence, it is nearly impossible to solve the problem even without constraints. Using hierarchical methods, these MDPs can be transformed into a semi-Markov decision process (SMDP) which only needs to be solved at certain landmark states. In the deterministic robotics motion planning community, sampling based algorithms like probabilistic roadmaps (PRM) and rapidly exploring random trees (RRTs) have been successful in solving very high dimensional deterministic problem. However they are not robust to system with uncertainties in the system dynamics and hence, one of the primary objective of this work is to generalize PRM/RRT to solve motion planning with uncertainty. We first present generalizations of randomized sampling based algorithms PRM and RRT, to incorporate the process uncertainty, and obstacle location uncertainty, termed as "generalized PRM" (GPRM) and "generalized RRT" (GRRT). The controllers used at the lower level of these planners are feedback controllers which ensure convergence of trajectories while mitigating the effects of process uncertainty. The results indicate that the algorithms solve the motion planning problem for a single agent in continuous state/control spaces in the presence of process uncertainty, and constraints such as obstacles and other state/input constraints. Secondly, a novel adaptive sampling technique, termed as "adaptive GPRM" (AGPRM), is proposed for these generalized planners to increase the efficiency and overall success probability of these planners. It was implemented on high-dimensional robot n-link manipulators, with up to 8 links, i.e. in a 16-dimensional state-space. The results demonstrate the ability of the proposed algorithm to handle the motion planning problem for highly non-linear systems in very high-dimensional state space. Finally, a solution methodology, termed the "multi-agent AGPRM" (MAGPRM), is proposed to solve the multi-agent motion planning problem under uncertainty. The technique uses a existing solution technique to the multiple traveling salesman problem (MTSP) in conjunction with GPRM. For real-time implementation, an ?inter-agent collision detection and avoidance? module was designed which ensures that no two agents collide at any time-step. Algorithm was tested on teams of homogeneous and heterogeneous agents in cluttered obstacle space and the algorithm demonstrate the ability to handle such problems in continuous state/control spaces in presence of process uncertainty.

La present tesi proposa una metodologia de disseny conceptual d'estacions depuradores d'aigües residuals (EDAR) mitjançant la combinació del procés de decisió jeràrquic i l'anàlisi de decisions multicriteri. El document s'inicia amb una breu introducció als principals camps abordats pel treball: el disseny dels processos químics en general, el disseny de les estacions depuradores d'aigües residuals en particular, i l'anàlisi de decisions multicriteri aplicada a la gestió ambiental. Seguidament, es fixen els objectius del treball i es descriuen tant la metodologia com el material de suport informàtic utilitzats. Per validar i contrastar la metodologia de disseny presentada, es desenvolupa un cas d'estudi on es porta a terme el disseny conceptual d'una EDAR que presenta els mateixos requeriments que l'EDAR que opera actualment al municipi de Granollers. Inicialment es presenta la informació de partida i tot seguit es defineixen els objectius de disseny, així com el conjunt de criteris que s'utilitzaran per avaluar en quina mesura es compleixen aquests objectius. Els objectius de disseny són de diferents tipus: ambientals, tècnics, socials i econòmics, i el conjunt de criteris utilitzats, concretament 33, també es classifica segons aquestes quatre categories. Cadascun dels criteris presenta un determinat pes d'importància relativa en la presa de decisions. Finalment, es desenvolupa tot el procés de decisió fins a obtenir el disseny complet de l'EDAR. El procés de decisió s'ha dividit en dues parts diferenciades però que alhora s'entrellacen: la línia d'aigua i la línia de fang. El procés de decisió presenta un total de divuit qüestions amb un màxim de quatre alternatives per pregunta (dotze qüestions corresponen a la línia d'aigua, i sis a la línia de fangs). Per solucionar cadascuna d'aquestes qüestions, s'avaluen les alternatives proposades respecte a un conjunt de criteris triats de la llista inicial. Aplicant el procés de decisió multicriteri anomenat SMART (simple multiattribute rating technique), es combinen els resultats de les alternatives respecte a cada criteri, tenint en compte la importància de cada criteri per obtenir un sol valor per alternativa. Per quantificar els criteris referents a l'operació del procés i les de tipus econòmic s'han utilitzat els programes GPS-X i CapdetWorks respectivament. Pel que fa als criteris no quantificats mitjançant aquests programes, s'han resolt de manera qualitativa i mitjançant manuals de disseny i també tenint en compte l'opinió d'experts en aquest camp. L'alternativa que obté un pes més elevat és la recomanada per al procés de decisió. El cas d'estudi finalitza un cop s'obté el disseny complet de l'EDAR. Per integrar tots aquests elements que hem esmentat i donar suport al desenvolupament del procés de decisió s'ha utilitzat el programa DRAMA (Design Rationale Management). A continuació, es fa una anàlisi comparativa entre l'EDAR que hi ha actualment al municipi de Granollers i l'EDAR resultat del cas d'estudi. Es descriu el diagrama de flux que conforma l'EDAR de Granollers i el diagrama de flux de l'EDAR resultat de l'estudi, se'n fa una anàlisi comparativa justificant cadascuna de les decisions preses en el cas d'estudi i, finalment, es fa una discussió de resultats on es reflecteixen els avantatges associats d'aplicar la metodologia de disseny conceptual proposada. Finalment, es presenten les conclusions de la tesi. Els principals resultats de la tesi es van publicar el 2002 a la revista internacional Industrial and Engineering Chemistry Research (N. Vidal, R. Bañares-Alcántara, I. Rodríguez-Roda i M. Poch: "Design of wastewater treatment plants using a conceptual design methodology", Industrial and Engineering Chemistry Research, 41 (20), pàg. 4993-5005) i la continuació de la línia de recerca al Laboratori d'Enginyeria Química i Ambiental de la UdG ha comportat la presentació del treball de recerca de Xavi Flores "Procés de decisió jeràrquic combinat amb anàlisi multicriteri per al suport al disseny conceptual de sistemes de fangs actius d'una estació depuradora d'aigües residuals" i la presentació dels resultats parcials al congrés internacional de la 9th IWA Conference on Design, Operation and Economics of Large Wastewater Treatment, que va tenir lloc el setembre passat a Praga ("Combining hierarchical decision process with multi-criteria analysis for conceptual design of WWTP", X. Flores, N. Vidal, A. Bonmatí, J. B. Copp i I. Rodríguez-Roda). / This thesis proposes a methodology for the conceptual design of wastewater treatment plants (WWTP) via a combination of a hierarchical decision process and multicriteria decision analysis. We begin with a brief introduction into the main fields of study involved in this work: the design of chemical processes in general; the design of wastewater treatment plants in particular and multicriteria decision analysis as applied to environmental management. We go on to outline the objectives of the study and then describe our methodology as well as the computer-based support tools used. In order to evaluate and contrast our design methodology, we present a study case in which a conceptual design is developed for a WWTP which has the same requirements as the actual WWTP currently in operation in the town of Granollers. First, we present the initial information and then define the design objectives, as well as the set of criteria that will be used in order to evaluate the degree to which the objectives have been met.The design objectives are of different types: environmental, technical, social and economical; the set of criteria, of which there are 33 in all, are also classified into these four categories. Each of the criteria has a specific weighting in terms of their importance in taking decisions. Next, we go through the whole decision process leading to the completion of the design of the WWTP. The decision process has been divided into two parts which are differentiated but at the same time, interconnected: the water line and the sludge line. The decision process involves a total of eighteen questions (twelve for the water line and six for the sludge line) with a maximum of four alternatives per question. In order to answer each question, the proposed alternatives are evaluated in relation to a set of criteria chosen from the initial list. Applying the multicriteria decision process known as SMART (simple multiattribute rating technique), the results for the alternatives with respect to each criteria are combined, bearing in mind the importance of each criteria, in order to get a single value for each alternative. To get the results for those alternatives relating to the operation of the process and those to do with economical factors, we used the GPS-X and CapdetWorks programmes, respectively. The criteria not quantified by means of these programmes were resolved by qualitative means and through the use of design manuals, in addition to taking expert opinion into account. The alternative that obtains the highest weighting is the one which is recommended by the decision process. The study case is completed once a complete design of the WWTP is obtained. In order to integrate all the elements we have mentioned, and to assist the development of the decision process, we employed the programme known as DRAMA (Design Rationale Management). We then go on to give a comparative analysis between the real WWTP in Granollers and the WWTP resulting from our study case. We describe and compare the flow diagrams in both cases, providing justification for each of the decisions taken in the study case and then discuss the results, reflecting on the advantages to be gained from using the methodology of conceptual design we propose. Finally, we present the conclusions of our thesis.The main results of this thesis were published, in 2002, in the international magazine, Industrial and Engineering Chemistry Research (N. Vidal, R. Bañares-Alcántara, I. Rodríguez-Roda and M. Poch: "Design of wastewater treatment plants using a conceptual design methodology", Industrial and Engineering Chemistry Research, 41 (20), pages 4993-5005). Continuing work in this line of research at the Laboratori d'Enginyeria Química i Ambiental at the University of Girona has led to the research work by Xavi Flores, Procés de decisió jeràrquic combinat amb anàlisi multicriteri per al suport al disseny conceptual de sistemes de fangs actius d'una estació depuradora d'aigües residuals (A hierarchical decision process combined with multicriteria analysis to assist conceptual design of active sludge systems in a wastewater treatment plant) and the presentation of the preliminary results at the 9th IWA Conference on Design, Operation and Economics of Large Wastewater Treatment, which took place in September, 2003, in Prague ("Combining hierarchical decision process with multi-criteria analysis for conceptual design of WWTP", X.

En ésta tesis se estudian 2 aspectos de la toma decisiones. Primero, se investiga la forma en que las personas categorizan atributos numéricos. Se presenta y se prueba experimentalmente un modelo del proceso mental que usan las personas para trasformar una cantidad en una categoría verbal. Bajo ciertas condiciones situacionales, el modelo es capaz de predecir conceptualizaciones verbales. Segundo, se exploran las interconexiones entre la información cognitiva y emocional durante la decisión. Se elaboran y se prueban experimentalmente cuatro modelos de la forma en que se combina la información cognitiva y emocional durante el proceso de elección, para determinar el valor de una alternativa. Los modelos muestran una alta capacidad de predicción. Esta varía en función de (1) la interacción de la información verbal y numérica con la capacidad cognitiva situacional del individuo y (2) la correlación entre los juicios cognitivos y las reacciones emocionales. / The present dissertation investigates two aspects of decision making: First, I study the way in which people understand and categorize numerical attributes of products. I develop and experimentally test a model of the mental process people use to transform a quantitative attribute into a verbal category. Under certain environmental conditions, the model is able to predict the verbal conceptualization of people. Second, I explore the interconnections of cognitive and emotional information during the process of decision making. I propose and experimentally test four different models of the way cognitive and affective information is combined during the decision making process in order to determine the value of an alternative. The models display a high predictive power. Their performance is influenced by (1) the interaction of verbal and numerical information with the situational cognitive capacities of the individual and (2) by the correlation of cognitive judgments and affective reactions.

Les travaux de cette thèse visent à mettre en place une gestion prédictive sous incertitudes de la ressource en eau pour les réseaux de voies navigables. L'objectif est de proposer un plan de gestion de l'eau pour optimiser les conditions de navigation de l'ensemble du réseau supervisé sur un horizon spécifié. La solution attendue doit rendre le réseau résilient aux effets probables du changement climatique et aux évolutions du trafic fluvial. Dans un premier temps, une modélisation générique d'une ressource distribuée sur un réseau est proposée. Celle-ci, basée sur les processus décisionnels markoviens, prend en compte les nombreuses incertitudes affectant les réseaux considérés. L'objectif de cette modélisation est de couvrir l'ensemble des cas possibles, prévus ou non, afin d'avoir une gestion résiliente de ces réseaux. La seconde contribution consiste en une distribution du modèle sur plusieurs agents afin de permettre son passage à l'échelle. Ceci consiste en une répartition des capacités de contrôle du réseau entre les agents. Chaque agent ne possède ainsi qu'une connaissance locale du réseau supervisé. De ce fait, les agents ont besoin de se cordonner pour proposer une gestion efficace du réseau. Une résolution itérative avec échanges de plans temporaires de chaque agent est utilisée pour l'obtention de politiques de gestion locales à chaque agent. Finalement, des expérimentations ont été réalisées sur des réseaux réels de voies navigables françaises pour observer la qualité des solutions produites. Plusieurs scénarios climatiques différents ont été simulés pour tester la résilience des politiques produites. / The work of this thesis aims to introduce and implement a predictive management under uncertainties of the water resource for inland waterway networks. The objective is to provide a water management plan to optimize the navigation conditions of the entire supervised network over a specified horizon. The expected solution must render the network resilient to probable effects of the climate change and changes in waterway traffic. Firstly, a generic modeling of a resource distributed on a network is proposed. This modeling, based on Markovian Decision Processes, takes into account the numerous uncertainties affecting considered networks. The objective of this modeling is to cover all possible cases, foreseen or not, in order to have a resilient management of those networks. The second contribution consists in a distribution of the model over several agents to facilitate the scaling. This consists of a repartition of the network's control capacities among the agents. Thus, each agent has only local knowledge of the supervised network. As a result, agents require coordination to provide an efficient management of the network. An iterative resolution, with exchanges of temporary plans from each agent, is used to obtain local management policies for each agent. Finally, experiments were carried out on realistic and real networks of the French waterways to observe the quality of the solutions produced. Several different climatic scenarios have been simulated to test the resilience of the produced policies.

Nas papelarias, o mesmo ocorre com a compra de instrumentos de escrita. Nesta dissertação é analisado o processo de compra de lapiseiras. Atualmente existe uma infinidade de modelos de lapiseiras com diferentes cores, estampas, cheiros, preços e fornecedores. Como escolher para que tenham alto giro no ponto-de-venda, minimizando os custos e maximizando os ganhos, torna-se o grande desafio para a organização que pretende continuar competitiva. Para aumentar o conhecimento sobre esse processo, esta dissertação teve como propósito investigar as variáveis que influenciam a decisão do comprador varejista, dono de papelaria. Foram realizados dois estudos de caso com papelarias. Por fim, descobriu-se que a decisão do comprador de lapiseiras não se restringe ao produto. Existem diversas variáveis que podem influenciar a sua decisão, como o representante, a distribuição efetiva, a garantia e o marketing (comunicação).
