This dissertation considers daily operations management for a fleet of trucks providing container pickup and delivery service to a port. Truck congestion at access points for ports may lead to serious inefficiencies in drayage operations, and the resultant cost impact to the intermodal supply chain can be significant. Recognizing that port congestion is likely to continue to be a major problem for drayage operations given the growing volume of international containerized trade, this research seeks to develop optimization approaches for maximizing the productivity of drayage firms operating at congested seaports. Specifically, this dissertation addresses two daily drayage routing and scheduling problems. In the first half of this dissertation, we study the problem of managing a fleet of trucks providing container pickup and delivery service to a port facility that experiences different access wait times depending on the time of day. For this research, we assume that the wait time can be estimated by a deterministic function. We develop a time-constrained routing and scheduling model for the problem that incorporates the time-dependent congestion delay function. The model objective is to find routes and schedules for drayage vehicles with minimum total travel time, including the waiting time at the entry to the port due to congestion. We consider both exact and heuristic solution approaches for this difficult optimization problem. Finally, we use the framework to develop an understanding of the potential impact of congestion delays on drayage operations, and the value of planning with accurate delay information. In the second half of this dissertation, we study methods for managing a drayage fleet serving a port with an appointment-based access control system. Responding to growing access congestion and its resultant impacts, many U.S. port terminals have implemented appointment systems, but little is known about the impact of such systems on drayage productivity. To address this knowledge gap, we develop a drayage operations optimization approach based on a column generation integer programming heuristic that explicitly models a time-slot port access control system. The approach determines pickup and delivery sequences with minimum transportation cost. We use the framework to develop an understanding of the potential efficiency impacts of access appointment systems on drayage operations. Findings indicate that the set of feasible drayage tasks and the fleet size required to complete them can be quite sensitive to small changes in time-slot access capacities at the port.

Många stora organisationer som myndigheter och banker arbetar med en monolitisk applikationsarkitektur som är ett gammalt sätt att strukturera applikationer. Flera faktorer som att attrahera och behålla talang, vara skalbar och flexibel, samt en bra tjänsteleverans driver dessa organisationer att byta till en mikrotjänstorienterad arkitektur. Att migrera stora applikationer och samtidigt leverera tjänster till kunder eller användare är en stor och svår uppgift. Problemet är att det inte finns tillräckligt med forskning om hur man arbetar under denna typ av modernisering av applikationsarkitekturen samtidigt som organisatorisk stabilitet upprätthålls. Denna studie syftar till att bättre förstå hur organisatorisk stabilitet kan upprätthållas under tider av stora tekniska förändringar i arbetssätt under övergångsperioden för arkitekturer. Studien utgick från följande forskningsfråga: Hur upprätthålls organisatorisk stabilitet under övergångsperioden för modernisering av arkitekturer under flytten mot mikrotjänster? Studien har baserats på en kvalitativ ansats, där en fallstudie har använts för att samla in empiriskt material. Studiens empiriska material har samlats in genom åtta semistrukturerade intervjuer med anställda med olika roller på myndigheten som utför ett storskaligt applikationsarkitektur projekt; containerprojektet. Datan analyserades med hjälp av tematisk analys. Studiens resultat visar hur både förberedande och löpande hantering är viktiga för framgång. I de förberedande stadierna är faktorer relaterade till risktagande och hantering av projektets arbetsstyrka viktiga att besluta om. När projektet väl har startat är det viktigt att aktivt arbeta med förändringsarbete och att vara flexibel, kommunicera med riktad information och hantera varje specifikt hinder noggrant. Studien visade också hur valet av teknik inte är avgörande för projektets framgång utan en metod för att nå dit. Resultaten har visat hur uppdelningen av en stor plan i mindre projekt, som vidare delas upp i faser, är en framgångsfaktor. Studien har bidragit med nya insikter till forskningen inom IT-hantering och applikationsarkitektur. / Many large organizations, such as government entities and banks, operate with a monolithic application architecture, an old way of structuring applications. Several factors including attracting and maintaining talent, being scalable and flexible, as well as a good service delivery, are driving these organizations to change toward a microservice-oriented architecture. To migrate large applications while simultaneously delivering the services to clients or users is a large and challenging task. The problem is that there is insufficient research on how to work during this type of application architecture modernization while maintaining organizational stability. This thesis aims to better understand how organizational stability can be maintained during times of disruptive technological change in the workspace during the transition period of architecture. The study utilized the following research question: How to maintain organizational stability in the transition period of architectural modernization moving towards microservices? The study has been based on a qualitative approach, where one case has been used in gathering empirical material. The study's empirical material has been collected through eight semi-structured interviews with employees of various roles at the Swedish agency performing a large-scale application architecture project; the containerization-project. The data were analyzed using thematic analysis. The thesis findings show how both preparatory and ongoing management contributions are essential for success. In the preparatory stages, factors related to risk-taking and managing the project workforce are essential to decide. Once the project has started, it is crucial to work on change management efforts actively and to be flexible, communicate with targeted information, and handle each specific obstacle carefully. The study also showed how the choice of technologies is not central to the project's success but a method to get there. The findings have shown how dividing a large plan into smaller projects, further divided into phases, is a success factor. The study contributed new insights to IT management and application architecture research.

Este projeto objetiva discutir as experiências na estiva de duas gerações de trabalhadores do Porto de Santos, localizado no litoral sul do Estado de São Paulo, a partir das mudanças na cultura e na organização do trabalho decorrentes da introdução dos contêineres, na década de 1960, e da promulgação da Lei de Modernização dos Portos, em 1993. O trabalho pretende analisar este processo por meio de uma investigação empírica com pais e filhos estivadores, a fim de identificar as diferentes percepções das mudanças no setor portuário. O objetivo é o de descrever como cada geração vivenciou as transformações impostas pelo novo cenário de produção e de que forma realizou-se o processo de herança e de transmissão da cultura da estiva. Por meio de um estudo empírico com estivadores de duas gerações espera-se identificar as diferentes práticas vividas no âmbito do trabalho e na esfera social. A história oral é o principal aporte metodológico para captar a experiência e buscar a memória dos estivadores. Desta forma, a pesquisa debate sobre a herança da cultura da estiva entre pais e filhos e as permanências e as rupturas na transmissão geracional / This project discusses the work experiences of two generations of stevedoring workers at the Port of Santos, located on the southern coast of São Paulo. We consider the changes in the culture and the organization of work due to the introduction of containers, in the 1960s, and the creation of the Port Modernization Law in 1993. The study aims to examine this process through an empirical research with parents and sons, all stevedores, in order to identify the different perceptions of the changes occurred in the port sector with the 1993´s Law. The objective is to describe how each generation has experienced the changes imposed by the new production scenario and how the process of inheritance and transmission of the culture of stowage works. Considering this empirical study of two generations of stevedores we expect to identify different experiences in the work of stevedoring and in the social sphere. Oral history is the main methodological approach to capture the experiences and to register the memory of the stevedores. This research debates the heritage of culture stowage and the permanence and ruptures in the generational succession

Investigação crítica dos processos de intervenção urbana em áreas centrais históricas. Analisa o aprofundamento das formas de segregação causadas pela valorização desses espaços, a redefinição do papel da cultura e a contraposição entre discursos e políticas, revelando a contradição entre produção socializada do espaço e sua apropriação privada. Discute aspectos do processo de empresariamento da produção da cidade, que incorpora o Patrimônio Cultural de áreas históricas às dinâmicas de promoção das cidades no mercado mundial, no qual a diferenciação é fundamental à competitividade. Trata-se da mercantilização da cultura que resulta na banalização da paisagem urbana, reduz e simplifica aspectos culturais, convertidos em objetos de consumo. Propõe o estudo de intervenções realizadas no Centro Histórico de Salvador e no Bairro do Recife. Para tanto, estabelece marcos conceituais específicos, definidos a partir dos elementos definidores da Urbanalização e do Processo de Containerização do Espaço Urbano e de questões relativas à preservação do Patrimônio Cultural, considerando-se as relações entre Patrimônio Arquitetônico, Patrimônio Imaterial e as formas de vivência estabelecidas no território. Nesse sentido, o turismo, que privilegia as atividades de comércio e serviço em detrimento da habitação, é a chave de inserção dos marcos conceituais propostos e revela o processo de substituição e/ou afastamento dos grupos de usuários locais. Em nossas análises encontramos, no lugar do Turismo Cultural, apresentado como um modelo adequado para conciliar rentabilidade econômica, melhoria da qualidade do ambiente urbano e preservação do Patrimônio Cultural, um turismo predatório, direcionado para o mercado e voltado à média e alta renda, situação que privilegia grupos específicos direcionados ao consumo e compromete significativamente Identidades Culturais anteriormente estabelecidas. Em meio ao Processo de Privatização do Espaço Urbano, observa-se o comprometimento da cultura local face à ausência de seus agentes produtores e a desarticulação da dinâmica urbana cotidiana. A preocupação com essa temática se justifica porque o processo de conformação de novas dinâmicas urbanas compromete, ao menos em parte, a paisagem urbana anteriormente constituída. Sem as formas de apropriação e usos cotidianos anteriores, atrelados ao Patrimônio Imaterial e aos vínculos estabelecidos com o tempo, o que concede ao Patrimônio Arquitetônico e ao espaço urbano características específicas, vemos a transformação da paisagem em um cenário artificial, vigiado e controlado, para usos dirigidos, em horários determinados. Neste quadro de análise, a tese pretende contribuir com o debate sobre as formas contemporâneas de produção do espaço urbano, especialmente quanto ao papel das Áreas Centrais Históricas, levando à reflexão quanto às nuances entre a preservação de sua paisagem particular e os processos de banalização a que estão sujeitas. / Critical investigation of the urban intervention processes in historic central areas. It analyzes the deepening of the segregation forms caused by the appreciation of these spaces, the redefinition of the culture role and the contrast between discourses and policies, revealing the contradiction between socialized production of space and its private appropriation. It discusses aspects of the production of the city entrepreneurship process, which incorporates the Cultural Patrimony of historical areas to the promoting dynamic of the cities in the world market, in which differentiation is the key to competitiveness. This is the commodification of culture that results in the trivialization of the urban landscape, reduces and simplifies the cultural aspects converted into objects of consumption. It proposes the study of interventions realized in the historic center of Salvador and in the Recife District. To do so, it establishes specific conceptual frameworks, defined from the defining elements of the Urbanalization and Containerization Process of the Urban Space and of issues related to the preservation of the Cultural Patrimony, considering the relationship between Architectural Patrimony, Intangible Patrimony and ways of living established in the territory. In this sense, tourism, which focuses on the activities of trade and service over housing, is the key of the integration of proposed conceptual frameworks and reveals the process of replacement and/or removal of local user groups. In our analysis we have found, in the place of Cultural Tourism, presented as a suitable model for reconciling economic profitability, improvement of the urban environment quality and preservation of Cultural Patrimony, a predatory tourism, directed to the market and geared to middle and high-income, status which privileges specific groups targeted to consumption and significantly undermines Cultural Identities previously established. Amid the Privatization Process of Urban Space, there is the commitment of the local culture with the absence of its producing agents and the disarticulation of the quotidian urban dynamics. The concern with this topic is justified because the process of shaping new urban dynamics compromises, at least in part, the urban landscape previously constituted. Without the appropriation forms of and earlier quotidian use, linked to the Intangible Patrimony and to the links established along the time, which gives to the Architectural Patrimony and to the urban space specific characteristics, we see the transformation of the landscape in an artificial setting, monitored and controlled to directed uses, at certain times. In this framework of analysis, the thesis aims to contribute to the debate on contemporary forms of urban space production, especially regarding to the role of Historical Central Areas, leading to a reflection about the nuances between preserving their particular landscape and the trivialization processes to which they are subjected.

L’accélération de la globalisation des échanges et le constat d’une certaine banalisation des formes urbaines depuis une trentaine d’années ont fait émerger un questionnement sur le devenir patrimonial et l’urbanité des métropoles portuaires.Qu’il s’agisse d’un héritage industriel ou technique lié à leur activité, de bâtiments historiques protégés ou d’édifices réalisés sur des sites libérés par la délocalisation des activités portuaires sous l’effet de la massification des marchandises, la morphologie des métropoles portuaires interroge les configurations résultant de cette phase intense de mondialisation urbaine. Elle constitue de ce fait un « laboratoire » permettant d’observer à quel point, en réalité, cette évolution est protéiforme et contrastée. Les villes portuaires de Gênes, du Havre et de New York – choisies pour les décalages qu’elles proposent, tant en termes d’échelle que les formes urbaines – permettent d’approcher de façon critique l’évolution de l’urbanité de ces métropoles depuis près d’un demi-siècle, au-delà des formules convenues de la production d’une architecture standardisée et de la mise en œuvre de « grands récits » homogénéisateurs sur ces territoires urbains en mutation. / The acceleration of the exchanges at a worldwide scale and the observation of a kind of globalization of urban forms over the past three decades have raised issues about the future of heritage and the urbanity of the port cities. Whether it concerns the industrial or technical heritage linked to their initial activity, protected historic buildings or buildings erected on urban sites liberated by the relocation of port activities due to the massive containerization of goods, the morphology of port metropolises questions the configurations resulting from this phase of urban globalization. It constitutes a true "laboratory", allowing to observe to what extent this evolution is quite protean and contrasted. The port cities of Genoa, Le Havre andNew York - chosen for the discrepancies they offer, both in terms of scales and urban forms - make it possible a critical approach of the evolution of the urbanity of these metropolises for half a century, so far from the agreed formulas of banalization, production of a standardized architecture and implementation of "great stories" homogenizing on these metropolitan areasin mutation.
