<p>In infrastructure construction projects especially bridge investments, the most critical decisions that significantly affect the whole bridge LCC are the early stages decisions. Clearly, it's more beneficial to correctly choose the optimum bridge than to choose the optimum construction or repair method.</p><p>The ability of a bridge to provide service over time demands appropriate maintenance by the agency.

The WWP units which are already existed in different parts of the world have been studied to identify its success, failure and different parameters associated with its suboptimal performance. The performance of WWP depends on three parameters namely pump, hydraulics, control system and pump station. These parameters are interdependent and must be carefully matched to achieve efficient WWP system. Nowadays the scenario has changed where organizations has started looking increasingly at the t

Environmental aspect of pavement, unlike its economic counterpart, is seldom considered in the theoretical study and field practices. As a highly energy and material intensive infrastructure, pavement has great potential to contribute to the environment protection, which, in root, depends on the in-depth understanding of the environmental impacts, holistically and specifically. A life cycle assessment (LCA) model is used to fulfill the goal. This research firstly carried out extensive literature review of LCA studies on pavement to identify the major research gaps, including: incompleteness of

Seismic designs of building structures are currently made based on the design criterion of life-safety and this requires that the structures do not collapse to compromise safety of people in the structure, but they can be designed to experience some damage. However, this design approach has allowed large economic losses primarily due to the damage to the nonstructural components at relatively moderate levels of seismic intensities. This led to a new thinking about design approach called performance-based design approach that satisfies the life-safety objective at the same time, reduces the eco

Fiber reinforced plastics are composite materials that offer a lower weight, while still mechanically perform at least as good as conventional materials such as steel. This makes them attractive for the automotive industry since the implementation of them in e.g. a car frame would enable the manufacturers to sell a more fuel efficient vehicle to the customer. The manufacturing of composites is however more energy intense than for steel and the recycling capabilities are limited.

This thesis will investigate the possibility of leasing as a 'greener' form of business transaction. With leasing, the customer pays for the service obtained form the product, but does not own the physical asset; ownership remains with the lessor. This has been claimed to increase resource productivity and close material loops. Numerous complications exist, however, such as tax regulations limiting operating leases to terms of 75% of the total product's life. In addition, no clear pattern has emerged in leasing practices, and in most cases manufacturers approach leasing on an ad hoc basis. Res

Para conseguir este propósito, durante los últimos años, se están empleando herramientas avanzadas para el diseño, simulación, optimización y síntesis de procesos químicos, las cuales permiten obtener procesos más eficientes y con el menor impacto ambiental posible. Uno de los aspectos más importantes a tener en cuenta para diseñar procesos más eficientes es la disminución del consumo energético. El consumo

Water shortage, water contamination, and the emerging challenges in sustainable water resources management (e.g., the likely impacts of climate change and population growth) necessitate adopting a reverse logistics approach, which is the process of moving wastewater from its typical final destination back to the water supply chain for reuse purposes. This practice not only reduces the negative impacts of wastewater on the environment, but also provides an alternative to withdrawal from natural water resources, forming a closed-loop water supply chain. However, the design of such a supply chain

El desenvolupament de sistemes energètics més sostenibles és un objectiu vital de les societats modernes que ha augmentat d'importància durant les darreres dècades. La minimització de la dependència dels combustibles fòssils per tal de millorar la sostenibilitat s'ha convertit en la meta pels investigadors i gestors juntament amb el desenvolupament de noves estratègies. Aquesta tesi introdueix la utilització conjunta de dues tècniques: l'anàlisi d'envolvent de dades (AED) i lanàlisi del cicle de vida (ACV) com eines adequades per assolir aquests reptes. S'ha analitzat l'ecoeficiència amb

Energy and cost performance optimization for commercial building system design is growing in popularity, but it is often criticized for its time consuming process. Moreover, the current process lacks integration, which not only affects time performance, but also investors’ confidence in the predicted performance of the generated design. Such barriers keep building owners and design teams from embracing life cycle cost consideration. This thesis proposes a computationally efficient design optimization platform to improve the time performance and to streamline the workflow in an integrated multi

Charnov's (1976) marginal value theorem has had success in predicting that animals will optimize net rate of gain when foraging in a patchy environment. The present study attempts to apply the marginal value theorem (MVT) to human behavior in a business setting in 3 Experiments. Businesses also attempt to optimize net rate of gain when choosing to discontinue one product in lieu of another using a product life cycle (PLC). Experiments 1 & 2 attempted to assess human behavior in a business context by varying time necessary to retool and monetary cost of retooling respectively. Experiment 3

This research encompasses the automated design and structural optimization of reinforced concrete slab frame bridges, considering investment costs and environmental impacts. The most important feature of this work is that it focusses on realistic and complete models of slab frame bridges rather than on optimization of only individual members or sections of a bridge. The thesis consists of an extended summary of publications and three appended papers. In the first paper, using simple assumptions, the possibility of applying cost-optimization to the structural design of slab frame bridges was in

Les stations d’épuration se tournent actuellement vers des installations de récupération d'énergie et des nutriments. Dans le même temps, elles sont soumises à une réglementation de plus en plus stricte en ce qui concerne l'environnement et la santé humaine. Face au défi ambitieux de réduire les coûts d'exploitation et les impacts environnementaux tout en garantissant la robustesse du procédé, il est nécessaire de développer des outils capables de fournir une évaluation intégrée du procédé. L’objectif de ce travail est de développer une plateforme réaliste et prédictive contenant trois aspects

El planeamiento urbano empieza a estar fuertemente focalizado en la provisión de redes adecuadas de infraestructuras que estimulen el desarrollo de una movilidad sostenible. Sin embargo, la integración de criterios ambientales en el diseño y gestión de las infraestructuras necesarias para el sustento de la movilidad urbana es mínima. Teniendo en cuenta la enorme extensión y la creciente inversión global en el despliegue de nuevas infraestructuras urbanas para el sustento de la movilidad sostenible, la carga ambiental aportada al espacio público de las ciudades puede ser significativa.
