Full textOrganisations tend to focus more and more on product and process development to increase their competitiveness. Several major organisations, among them ABB, have developed models aimed to more effectively control and manage product development processes. ABB is using its standardised model ABB Gate Model for this. The purpose of this thesis is to analyze how the introduction of ABB Gate Model has affected the outcome of decisions and also the decision-making in the product development process. The study is limited to elucidate the version of ABB Gate Model handling product development projects. No deeper study is conducted regarding the information used or the criteria for the gate decisions; instead, the focus is to findelements in basis for the decision- making that have a greater significance for the outcome at some gate or at specific types of gate decisions. The empirical data of the thesis has to a great extent been collected through interviews with respondents from both of the studied units and also the unit in charge of the implementation and development of ABB Gate Model. The study shows that ABB Gate Model does not to any significant extent affect the outcome of the decisions in the product development projects. In general, the same decisions are made as before and projects are seldom cancelled. The foremost effects of ABB Gate Model at the units are: increased clarity and support to the operational work, improved co- ordination between the units functional departments, and contributed to make essential aspects of the product development projects visible and taken into consideration.

Full textThis work presents functional composition (FC) as a new paradigm for combinational logic synthesis. FC is a bottom-up approach to synthesize Boolean functions, being able to evaluate the cost of intermediate sub-functions, exploring a larger number of different candidate combinations. These are interesting advantages when compared to the top-down behavior of functional decomposition. FC presents great flexibility to implement algorithms with optimal or suboptimal results for different applications. The proposed strategy presents good results for the synthesis of Boolean functions targeting different technologies. FC is based on the following principles: (1) the representation of logic functions is done by a bonded pair of functional and structural representations; (2) the algorithm starts from a set of initial functions; (3) simpler functions are associated to create more complex ones; (4) there is a partial order, enabling dynamic programming; (5) a set of allowed functions can be used in order to reduce execution time/memory consumption. This work presents functional composition algorithms for Boolean factoring, including optimal factoring, Boolean factoring considering the exclusive-OR operator, minimum decision chain computation and synthesis of functions considering only majority and inverter logic gates.

Full textO processo de tomada de decisão no seio das organizações e a definição das estratégias constituem desde sempre um dos maiores desafios para a Administração Pública, sobretudo se se considerar a forma cada vez mais rápida como a realidade se altera. Este processo é ainda mais exigente se for tido em conta a crescente necessidade das entidades públicas pautarem a sua atividade, por níveis de eficiência cada vez maiores. É com este pano de fundo que o presente estudo procura analisar a forma da tomada de decisão, no seio da comunidade escolar e medir o alcance dos seus efeitos. Estes efeitos não se cingem apenas à realidade educativa das escolas, na medida em que, sendo a escola uma importante parcela da comunidade é também sobre esta, que se produzem alterações. Para este enquadramento foi importante integrar a realidade Escola no meio onde existem outras instituições de ensino num contexto onde as instituições passaram a se reger segundo uma realidade concorrencial e nesta perspetiva, foi importante estuda-la com recurso à Teoria dos Jogos. Como opções metodológicas, a investigação adota o estudo caso e, nesse ambiente, recorre por um lado à análise documental no contexto escolar e, por outro, ao estudo estatístico como forma de relacionar variáveis e verificar hipóteses. O estudo aponta, como consequência da tomada de decisão, não apenas alterações sobre a realidade escolar, mas também sobre a realidade social envolvente.
One of the major challenges for Public Administration has always been the adoption within its various institutions of decision making processes that lead to optimal decision making and the design and implementation of effective strategies. Decision making in the Public Administration is perhaps more complex and demanding nowadays than it has ever been. This is not only because reality changes at a very fast pace, but also because of the increasing pressure put on public institutions to become more efficient. Having this context as background, the present study discusses decision making within schools, analyses one particular decision made by one school and carefully measures its implications. The study follows the Case Study method approach. The research done is based both on documental analysis and on statistical analysis as a way of finding associations between variables and testing hypothesis. Because the decision considered in the study is made in a situation where more than one school serves the same community and schools compete for students, Game Theory considerations are also used in the analysis of the decision. The study suggests that decisions made by one school may have unintended negative consequences for that school. It also suggests that such decisions may also have implications for the way competing schools interact and for the community that they serve.

Os problemas de decisão enfrentados atualmente são bastante complexos devido ao grande número de variáveis que devem consideradas na construção dos modelos. Atualmente os tomadores de decisão se utilizam de duas teorias diretamente interligadas conceitualmente, a Teoria da Decisão e a Teoria dos Jogos que o ajudam a escolher uma ação ou conjunto de ações disponíveis, no intuito de maximizar sua utilidade esperada. A primeira teoria usa uma caraterização profunda dos elementos estatísticos os que atuam em um problema de decisão, enquanto que a Teoria dos Jogos analisa as interações entre os agentes, quando a ação de um afeta diretamente o resultado dos demais. Analisar a metodologia de tomada de decisão na Teoria dos Jogos como uma aplicação da Teoria da Decisão foi o principal propósito deste trabalho. Este propósito foi alcançado pelo estabelecimento das relações entre os elementos que compõem a estrutura das duas teorias e da definição de um algoritmo de resolução sando Teoria da Decisão para resolver problemas de Teoria dos Jogos. Depois partiu-se para a aplicação deste algoritmo para resolução de problemas de jogos simultâneos e sequenciais de dois jogadores, om estratégias puras, mistas e jogos de informação in completa. P de-se constatar que a metodologia da Teoria da De são alcançados mesmos resultados da análise feita pela Teoria dos Jogos. Este resultado reforça o fato de que estas duas teorias trabalham sobre os mesmos princípios e que a relação entre estas é mais imbricada do que se imagina. No aso usando Teoria da Decisão deve-se fazer ajustes na forma de analise para considerar a racionalidade e a interação entre os agentes.

Understanding the relationship between dysfunctional behavior and confidence of managers in management is essential, as these factors may adversely affect the results and performance of businesses and undermine the organizational climate. The objective of this study was to understand the relationship between these two aspects, reliability and dysfunctional behavior. These results demonstrated that the presence of dysfunctional behavior affects the decision confidence of managers in management and was also verified that different than expected in theory the wages received not exerted great influence on the decisions taken by the subjects. A possible cause of this difference between the results obtained and the theory may be that the present study have extended the results of the task of Zhang (2008) from single period to multiple periods creating social ties among individuals, in addition, the test sample belongs to called generation Y, which has different values from those included in the theories and this is an issue that can be studied in future research. Besides worrying about the negative aspects of dysfunctional behavior, companies should be alert to the career expectations of generation Y, who will soon assume positions of leadership, because this generation is concerned with values other than the main salary, as free time , establishing lasting relationships with coworkers and with a good organizational climate.
Compreender a relação entre comportamento disfuncional e a confiança dos gestores na administração da empresa é fundamental, pois estes fatores podem afetar negativamente os resultados e desempenho das empresas e prejudicar o clima organizacional. O objetivo deste estudo foi compreender a relação entre estes dois aspectos, confiança e comportamento disfuncional. Os resultados deste trabalho demonstraram que a presença de comportamento disfuncional afeta a decisão de confiança dos gestores na administração da empresa e também foi possível verificar que diferente do esperado na teoria o salário recebido não exerceu grande influência nas decisões tomadas pelos sujeitos. Uma possível causa deste desvio entre os resultados obtidos e a teoria pode ser o fato da presente pesquisa ter estendido os resultados da tarefa de Zhang (2008) de período único para múltiplos períodos criando laços sociais entre os sujeitos, além disso, a amostra testada pertence a chamada geração Y, que possui valores diferentes dos preconizados nas teorias e este é um assunto que pode ser estudado em futuras pesquisas. Além de se preocuparem com os aspectos negativos do comportamento disfuncional, as empresas devem estar atentas às expectativas de carreira da geração Y, que em breve irá assumir cargos de liderança, pois esta geração está preocupada com outros valores além da remuneração principal, como tempo livre, estabelecimento de relações duradouras com os colegas de trabalho e com um bom clima organizacional.

Full textUnder de kommande decennierna förväntas efterfrågan på transport av varor och passagerare mångfaldigas, vilket innebär att behovet av hållbara transportlösningar är brådskande. En lovande lösning är konvojkörning, som visar stor potential att minska bränsleförbrukningen och driftskostnaderna för lastbilar. För att utnyttja fördelarna med konvojkörning till fullo behöver lastbilar koordineras för att effektivt mötas och bilda konvojer. Den här avhandlingen behandlar koordinering av lastbilar som kan bilda konvojer på transporthubbar, där vissa lastbilar måste vänta på andra lastbilar för att bilda konvojer, och det finns en belöning för konvojkörning och en kostnad för att vänta. Tre bidrag som behandlar konvojkoordinering presenteras i den här avhandlingen. Det första bidraget behandlar koordinering av lastbilar med förutbestämda rutter i ett transportnätverk med deterministiska eller stokastiska restider. Lastbilarna ägs av konkurrerande transportföretag, och varje lastbil beslutar om sina väntetider på hubbarna längs med sin rutt för att optimera sin driftskostnad. Vi antar att lastbilar bildar en konvoj om de avgår från en hubb och kör in på vägen samtidigt. Den strategiska interaktionen mellan lastbilar när de koordinerar för konvojbildning modelleras med icke-kooperativ spelteori, och vi betraktar Nashjämvikt som lösningskoncept när lastbilarna beslutar om sina väntetider i början av sina resor. I fallet med stokastiska restider utvecklar vi även lösningar där lastbilarna tillåts uppdatera sina väntetider längs med sina resor. I en simuleringsstudie över det svenska transportnätverket visas att när lastbilarna tillåts uppdatera sina väntetider uppnås en konjovkörningsgrad på 60%. I det andra bidraget utreds modeller för att dela på vinsten från konvojkörning. Fördelarna med konvojkörning är inte lika för alla lastbilar i en konvoj; vanligtvis är fördelen större för följarlastbilarna än för ledarlastbilen. Således kan incitamenten för transportföretag att samarbeta i form av konvojkörning vara låga om inte vinsterna från konvojkörning delas. Baserat på vinstdelningsmodeller formulerar vi konvojkoordineringsspel. I en simulering av en transporthubb utvärderar vi utfallet från konvojkoordinationsspelen. Det visar sig att den totala vinsten som uppnås när lastbilarna försöker maximera sina egna vinster, men vinsten från konvojkörning jämnas ut helt bland konvojmedlemmar, är nästan lika hög som när varje lastbil försöker att maximera den totala vinsten i systemet. I det sista bidraget studeras ett koordineringsproblem där lastbilar anländer till en transporthubb enligt en stokastisk ankomstprocess. Lastbilarna delar inte förhandsinformation om sina ankomster; detta kan vara känslig information att dela. En koordinator bestämmer, baserat på den statistiska sannolikhetsfördelningen av ankomster, när lastbilarna på transporthubben ska släppas iväg i form av en konvoj. Under antagandet att ankomsterna är statistiskt oberoende och likafördelade, visar vi att det är optimalt att släppa iväg lastbilarna från transporthubben i form av en konvoj när antalet lastbilar överskrider en viss tröskel. Detta bidrag visar att enkla och dynamiska koordineringsmetoder kan erhålla en hög vinst från konvojkörning, även under hög osäkerhet och begränsad förhandsinformation.

Full textOrganizational change and game theory were separately investigated over time. Due to lack of scientific research on the relationships of those two fields of knowledge, an investigation of the game theoretic applications in managing change was performed in this research. Game theoretic applications were structured concerning the analytical use of game theory, strategic formulation with game theory and equilibrium analysis. By a qualitative flexible research method, main problematic areas of organizational change were identified with suitable game theoretic applications. Those problem areas are: making cooperation and coalition in change, group dynamic difficulties and the problem of incentive rewards. In each problem area, game theoretic solutions were discussed to help managers to make better decisions. Four mechanisms were inferred to support the game theoretic analysis of change management problems. Those mechanisms are: sub games, practical games, specific modeling and behavioral studies of games. Finally, an instructional framework was developed to conclude findings and illuminate the game theoretic approach in organizational change.

Humanitarian and public health logistics systems are often characterized by decentralized decision makers in the form of response agencies who establish supply chains and the beneficiaries who access them. While classical models assume there is a single decision maker with a global objective and authority, decentralized systems consist of multiple decision makers, each with accomplishing his own objective and scope of control. The literature demonstrates that decentralized systems often perform poorly when compared to their hypothetical centralized counterparts. However, there exist few models in the literature to quantify the impact of decentralization and mechanisms for its mitigation are deficient. This research advances knowledge of decentralized systems through new game theory and optimization models, solution methodologies and theoretical characterizations of system performance. First, the author presents a literature review that synthesizes research regarding the facets of humanitarian operations that can benefit from the application of game theory. The author finds that models of decentralized behavior lack realism, neglecting sources of uncertainty, dynamism and personal preferences that influence individuals' decisions. These findings motivate the remaining components of the thesis. Next, the author focuses on decentralization on the part of response agencies who open service facilities. Decentralization can adversely impact patient access and equity, both critical factors in humanitarian contexts. A dynamic, robust facility location model is introduced to enable a comparison between a given decentralized response and a hypothetical coordinated response using identical resources. The value of the model is demonstrated through a computational study of the response to a recent cholera epidemic. Finally, the author introduces game theory models that represent the decisions of beneficiaries seeking relief. The models account for distance, congestion, and the relative importance an individual places on the two. The author constructs an algorithm that computes a decentralized solution in polynomial time. The author quantifies decentralized system performance in comparison to centralized control, bounding the cost of decentralized decision making for the least and most costly outcomes. The author identifies coordination mechanisms encourage centrally optimal decisions within decentralized systems.

Full textENGLISH ABSTRACT: In computer Go, moves are typically selected with the aid of a tree search algorithm. Monte-Carlo tree search (MCTS) is currently the dominant algorithm in computer Go. It has been shown that the inclusion of domain knowledge in MCTS is able to vastly improve the strength of MCTS engines. A successful approach to representing domain knowledge in computer Go is the use of appropriately weighted tactical features and pattern features, which are comprised of a number of hand-crafted heuristics and a collection of patterns respectively. However, tactical features are hand-crafted specifically for Go, and pattern features are Go-specific, making it unclear how they can be easily transferred to other domains. As such, this work proposes a new approach to representing domain knowledge, decision tree features. These features evaluate a state-action pair by descending a decision tree, with queries recursively partitioning the state-action pair input space, and returning a weight corresponding to the partition element represented by the resultant leaf node. In this work, decision tree features are applied to computer Go, in order to determine their feasibility in comparison to state-of-the-art use of tactical and pattern features. In this application of decision tree features, each query in the decision tree descent path refines information about the board position surrounding a candidate move. The results of this work showed that a feature instance with decision tree features is a feasible alternative to the state-of-the-art use of tactical and pattern features in computer Go, in terms of move prediction and playing strength, even though computer Go is a relatively well-developed research area. A move prediction rate of 35.9% was achieved with tactical and decision tree features, and they showed comparable performance to the state of the art when integrated into an MCTS engine with progressive widening. We conclude that the decision tree feature approach shows potential as a method for automatically extracting domain knowledge in new domains. These features can be used to evaluate state-action pairs for guiding searchbased techniques, such as MCTS, or for action-prediction tasks.
AFRIKAANSE OPSOMMING: In rekenaar Go, word skuiwe gewoonlik geselekteer met behulp van ’n boomsoektogalgoritme. Monte-Carlo boomsoektog (MCTS) is tans die dominante algoritme in rekenaar Go. Dit is bekend dat die insluiting van gebiedskennis in MCTS in staat is om die krag van MCTS enjins aansienlik te verbeter. ’n Suksesvolle benadering tot die voorstelling van gebiedskennis in rekenaar Go is taktiek- en patroonkenmerke met geskikte gewigte. Hierdie behels ’n aantal handgemaakte heuristieke en ’n versameling van patrone onderskeidelik. Omdat taktiekkenmerke spesifiek vir Go met die hand gemaak is, en dat patroonkenmerke Go-spesifiek is, is dit nie duidelik hoe hulle maklik oorgedra kan word na ander velde toe nie. Hierdie werk stel dus ’n nuwe verteenwoordiging van gebiedskennis voor, naamlik besluitboomkenmerke. Hierdie kenmerke evalueer ’n toestand-aksie paar deur rekursief die toevoerruimte van toestand-aksie pare te verdeel deur middel van die keuses in die besluitboom, en dan die gewig terug te keer wat ooreenstem met die verdelingselement wat die ooreenstemmende blaarnodus verteenwoordig. In hierdie werk, is besluitboomkenmerke geëvalueer op rekenaar Go, om hul lewensvatbaarheid in vergelyking met veldleidende gebruik van taktiek- en patroonkenmerke te bepaal. In hierdie toepassing van besluitboomkenmerke, verfyn elke navraag in die pad na onder van die besluitboom inligting oor die posisie rondom ’n kandidaatskuif. Die resultate van hierdie werk het getoon dat ’n kenmerkentiteit met besluitboomkenmerke ’n haalbare alternatief is vir die veldleidende gebruik van taktiek- en patroonkenmerke in rekenaar Go in terme van skuifvoorspelling as ook speelkrag, ondanks die feit dat rekenaar Go ’n relatief goedontwikkelde navorsingsgebied is. ’n Skuifvoorspellingskoers van 35.9% is behaal met taktiek- en besluitboomkenmerke, en hulle het vergelykbaar met veldleidende tegnieke presteer wanneer hulle in ’n MCTS enjin met progressiewe uitbreiding geïntegreer is. Ons lei af dat ons voorgestelde besluitboomkenmerke potensiaal toon as ’n metode vir die outomaties onttrek van gebiedskennis in nuwe velde. Hierdie eienskappe kan gebruik word om toestand-aksie pare te evalueer vir die leiding van soektog-gebaseerde tegnieke, soos MCTS, of vir aksie-voorspelling.

Se muestra cómo la incorporación de la democracia interna (en particular, la introducción de las primarias) puede ayudar a resolver el conflicto dentro del partido. En segundo lugar, se estudia el problema que se crea cuando un grupo de agentes debe elegir un ganador entre ellos. Existe un ganador merecido a quien todos los agentes conocen. Sin embargo, cada agente es egoísta: siempre quiere ser el ganador. Se construye el mecanismo de veto, que siempre elige al ganador merecido independientemente de las preferencias egoístas de los agentes. En tercer lugar, se cuestiona la suposición de la nocividad de la regla de votación dictatorial indeseable. El objetivo del análisis es alejarse de la regla de votación dictatorial, buscando la regla que está más alejada de la regla dictatorial más cercana, e identificar las reglas que equilibren todas las reglas dictatoriales. El primer resultado encuentra la regla de pluralidad inversa como la más alejada de la regla de votación dictatorial más cercana. Desafortunadamente, esta regla viola algunas propiedades aparentemente deseables. El segundo resultado concluye que la regla de pluralidad es la que equilibra el acuerdo entre todas las reglas de votación dictatoriales. En cuarto lugar, se analiza la relación entre dos propiedades incompatibles, la dictadura y la manipulabilidad, en términos de ciertos índices de manipulabilidad y no-dictadura. El objetivo es arrojar algo de luz sobre el problema de elegir entre las reglas de votación.
This thesis consists of four independent chapters related to collective decision-making. First, intra-party dynamics is analyzed in the presence of intra-party conflict. It is shown how the incorporation of intra-party democracy (in particular, the introduction of primaries) may help to resolve intra-party conflict. Second, the problem arising when a group of agents must choose a winner among themselves is studied. There exists a deserving winner, whom all agents know. Nevertheless, each agent is selfish: he always wants to be the winner. A veto mechanism is proposed that always chooses the deserving winner irrespective of the selfish preferences of the agents. Third, the assumption of the harmfulness of dictatorial voting rule is questioned. The aim is to get away from dictatorial voting rules, by searching for the rule that is the furthest away from the closest dictatorial rule, and to identify the rules balancing all dictatorial rules. The first result finds the reverse-plurality rule as the furthest from the closest dictatorial voting rule. Unfortunately, this rule violates some apparently desirable properties. The second result states that the plurality rule is the one that balances the agreement between all dictatorial voting rules. Fourth, the relationship between two incompatible properties of dictatorship and manipulability is analyzed, in terms of certain indices of manipulability and non-dictatorship. The aim is to shed some light on the problem of choosing between voting rules.
