Resumen
Maintenance is an extremely important issue in the industry. Testimony to this fact is that European companies spend about 140 billion euro per year on maintenance activities. In Sweden alone, the annual cost of maintenance and related activities reaches 250 billion crowns and these costs are the costs incurred when maintenance jobs are performed and does not include the consequences of poor maintenance with which the costs would be significantly higher. The new paradigm in the manufacturing sector identifies utilization of production resources as a main competitive weapon. To meet the high demands of the industry like high efficiency, enhanced customization and high speed of delivery, a much higher operational availability and capability of production systems have to be achieved. In this context, maintenance becomes an important strategic issue. The objectives of this study are to develop a dynamic LCC model supporting decision making in the early stages of investment and production development process allowing estimating and optimizing life cycle costs of production equipment including maintenance considerations. It will give the concerned stakeholders a better chance of estimating the whole life cycle costs and select proper design alternative for new investments. It can be used as a tool for the justification of investment in Condition Based Maintenance technologies which is underestimated in present calculation models.

Resumen
Die vorliegende Arbeit untersucht Wesensmerkmale des Life Cycle Costing (LCC, dt. Lebenszykluskostenrechnung) und dessen Anwendung veröffentlicht in Fachzeitschriften. Aufgrund der langen Historie des LCC seit Beginn der 30er Jahre, gibt es zu dem Forschungsthema bereits eine Vielzahl theoretischer und empirischer Studien. Dennoch existiert bis heute keine einheitliche Definition oder ein standardisierter methodischer Rahmen. Das Ziel dieser Arbeit ist es, LCC zu charakterisieren und eine sinnvolle Methode für die Klassifizierung der vorhandenen Forschungsarbeiten zu identifizieren um methodische und inhaltliche Unterschiede darzustellen. Angewandt wird die Methodik des Literature Review, respektive einer Mischform explorativ-induktiver, qualitativer und quantitativer Inhaltsanalyse. Den Prozess der Charakterisierung und Systematisierung leiten folgende Fragestellungen: Was sind die Motivatoren der Anwendung von LCC in Firmen? Gibt es ein standardisiertes Konzept analog zur Ökobilanz (LCA)? Was sind die wesentlichen Vorteile von LCC? Was ist momentan unbefriedigend erforscht? Wo und in welcher Form wird LCC angewandt? Ergeben sich aus F-1 bis F-4 spezifische Anwendungsbereiche? Zu Beginn erfolgt im Sinne der Vision des Life Cycle Thinking eine Erörterung möglicher Motivationen einer Zuwendung zu LCC aus unternehmerischer Entscheidungsperspektive. Dem folgt eine umfangreiche Analyse und Diskussion der wesentlichen Charakterzüge. Ausgehend dieser Erkenntnis ist ein Analyseraster abgeleitet um die zu bewertenden Studien geeignet zu kategorisieren. Ein direktes Ergebnis stellt die Evaluierung von 34 Studien zu LCC dar. Als mittelbare Ergebnisse der Systematisierung gelten die Erkenntnisse zur Wahl einer optimierten Suchstrategie und die Schaffung eines Startpunkts für Forscher, die sich zukünftig mit Detailfragen des LCC beschäftigen.

Resumen
Vor dem Hintergrund der zukünftigen Notwendigkeit einer nachhaltigen Energieversorgung beschäftigt sich die vorliegende Arbeit mit Technologien der regenerativen Energiequelle Solarenergie, insbesondere Photovoltaik (PV). Systeme zur Nutzung der unerschöpflich verfügbaren, sauberen und im Prinzip “frei Haus” gelieferten Energie der Sonne können eine bedeutsame Rolle in einer umweltverträglicheren Zukunft spielen. Allerdings ist die Herstellung der erforderlichen Komponenten heute i.d.R. noch energie- und kostenintensiv, weshalb für eine korrekte Bewertung dieser Technologien der gesamte Lebenszyklus betrachtet werden muss. Zur tieferen Analyse der PV wird die Methodik des Environmental Life Cycle Costing (ELCC) auf der Grundlage von drei Grundideen eingeführt. Konkret sind dies die Ausgangspunkte: Nachhaltigkeit, Lebenszyklusdenken und die Drei-Dimensionalität dieses Instrumentes durch die gemeinsame Betrachtung ökologischer, ökonomischer und technischer Aspekte in ihrem Zusammenspiel. Ausgehend von theoretischen Elementen der Ökobilanzierung (Life Cycle Assessment) und des Life Cycle Costings, verbunden mit den technischen Eigenschaften der Photovoltaik werden wichtigste Anforderungen und Schritte für die Durchführung eines ELCC für PV beschrieben. Mittels einer softwaregestützten Inhaltsanalyse wird im Anschluss der definierte Rahmen für ein ELCC für PV getestet (und modifiziert) gegen eine Auswahl von 135 bereits existierender Studien, die sich mit dem Lebenszyklus von PV-Technologien aus ökologischer und ökonomischer Sicht beschäftigen. Im Ergebnis hieraus können die wichtigsten Elemente eines ELCC für PV, wie beispielsweise ökologische Wirkungskategorien oder ökonomische Indikatoren, identifiziert werden (methodisches Feedback). In einem nächsten Schritt werden die Studien hinsichtlich ihrer “Qualität” bezogen auf ökologische, ökonomische und übergreifende Inhalte eines ELCC für PV bewertet. Auf diese Weise kann ein Inventar von Lebenszyklusanalysen für PV erstellt werden, das nach den Technologien und der inhaltlichen Qualität bezüglich eines ELCC strukturiert ist und für weitere Analysen als Grundlage dienen kann. Aus den bisherigen Ergebissen kann eine erste Einschätzung zum aktuellen Stand des ELCC für PV in der Literatur vorgenommen werden: Es existiert bereits ein großer Pool von Studien, die sich mit dem Lebenszyklus der PV beschäftigen. Mit Blick auf die Anforderungen eines ELCC für PV besteht jedoch Nachholbedarf in der Verbindung und gemeinsamen Betrachtung von hot spots und trade offs aus ökologischer und ökonomischer Perspektive. Der definierte theoretische Rahmen für ein ELCC für PV, die kodierten Studien sowie das erstellte Inventar von Lebenszyklusanalysen der PV können nun als Grundlage für weitere Analysen dienen. Insbesondere eine inhaltliche Auswertung der konkreten Ergebnisse von Studien kann so einen Benchmark und Orientierung für neue Lebenszyklusanalysen für PV-Technologien liefern
The special need of a sustainable energy supply in mind the technologies of the renewable source solar energy, especially photovoltaics (PV) is main subject of the present thesis. Using the inexhaustible, clean and “freely delievered” power from the sun solar devices may play a major role in a cleaner future, but, on the other hand, they are still energy consuming and expensive in their production which consequently demands a whole life cycle perspective when assessing this technology. For a closer look at PV the methodology of Environmental Life Cycle Costing (ELCC) is introduced by following three theoretical points of view. Namely these are sustainability, life cycle thinking and the three dimensional nature of this tool by regarding environmental, economic and technical aspects in their interaction. Based on theoretical elements of Life Cycle Assessment and Life Cycle Costing in combination with the technical background of photovoltaics main requirements and steps for performing an ELCC for PV are described. By executing software based content analysis the defined framework is checked (and modified) against a choice of 135 existing studies analyzing the life cycle of PV technologies from an environmental or economic perspective. As a result the main elements of an ELCC for PV, e.g. environmental impact categories and economic indicators, are identified (methodological feedback). Within the next step the existing studies are rated by their “quality” regarding the environmental, economic and more general parts of an ELCC for PV in order to create an inventory of life cycle studies for PV. This inventory is structured by technologies as well as quality of content respecting ELCC and might be used for further analyses. At this stage the results propose the possibility of a first estimate of the present status of ELCC for PV: until now there is a good pool of existing analyses of the life cycle of PV systems. But from an ELCC perspective the examination of common hot spots and trade offs between economic and environmental aspects should be expanded. The theoretical framework of ELCC for PV, the encoded studies and the inventory of life cycle analyses for PV are now the starting point for further analyses, especially of the individual outcome within studies, which will then pose a benchmark for new life cycle studies of PV technology

Resumen
The need for a more authoritative approach to investment decision-making and cost control has been a requirement of office spending for many years now. The commercial offices find itself in an increasingly demanding position to allocate its budgets as wisely and prudently as possible. The significant percentage of total spending on buildings demands a more accurate and adaptable method of achieving quality of service within the constraints on the budgets. By adoption of life cycle costing techniques with risk management, practitioners have the ability to make accurate forecasts of likely future running costs. This thesis presents a novel framework (Artificial Neural Networks and probabilistic simulations) for modelling of operating and maintenance historical costs as well as economic performance measures of LCC. The methodology consisted of eight steps and presented a novel approach to modelling the LCC of operating and maintenance costs of two sustainable commercial office buildings. Finally, a set of performance measurement indicators were utilised to draw inference from these results. Therefore, the contribution that this research aimed to achieve was to develop a dynamic LCC framework for sustainable commercial office buildings, and by means of two existing buildings, demonstrate how assumption modelling can be utilised within a probabilistic environment. In this research, the key themes of risk assessment, probabilistic assumption modelling and stochastic assessment of LCC has been addressed. Significant improvements in existing LCC models have been achieved in this research in an attempt to make the LCC model more accurate and meaningful to estate managers and high-level capital investment decision makers A new approach to modelling historical costs and forecasting these costs in sustainable commercial office buildings is presented based upon a combination of ANN methods and stochastic modelling of the annual forecasted data. These models provide a far more accurate representation of long-term building costs as the inherent risk associated with the forecasts is easily quantifiable and the forecasts are based on a sounder approach to forecasting than what was previously used in the commercial sector. A novel framework for modelling the facilities management costs in two sustainable commercial office buildings is also presented. This is not only useful for modelling the LCC of existing commercial office buildings as presented here, but has wider implications for modelling LCC in competing option modelling in commercial office buildings. The processes of assumption modelling presented in this work can be modified easily to represent other types of commercial office buildings. Discussions with policy makers in the real estate industry revealed that concerns were held over how these building costs can be modelled given that available historical data represents wide spending and are not cost specific to commercial office buildings. Similarly, a pilot and main survey questionnaire was aimed at ascertaining current level of LCC application in sustainable construction; ranking drivers and barriers of sustainable commercial office buildings and determining the applications and limitations of LCC. The survey result showed that respondents strongly agreed that key performance indicators and economic performance measures need to be incorporated into LCC and that it is important to consider the initial, operating and maintenance costs of building when conducting LCC analysis, respondents disagreed that the current LCC techniques are suitable for calculating the whole costs of buildings but agreed that there is a low accuracy of historical cost data.

Resumen
Life cycle costing methods can be applied to the procurement of some, but not all, spare parts. As a result, a decision model is needed to determine which spare parts should be considered for life cycle costing. This thesis discusses a decision model for determining the applicability of life cycle costing to spare part procurement. The thesis briefly reviews the application of the life cycle costing concept to the acquisition of major systems and associated spare parts. It then reviews current spare parts acquisition techniques and identifies critical criteria to be considered during the acquisition of spare parts using life cycle costing techniques. Finally, the thesis uses the identified characteristics to develop the decision model. Theses. (sdw)

In this study, we have examined the application of Lee analysis method to the construction and renovation stages of a building project. The application of the Lee analysis is currently limited to the very early stages of a project life, namely at the concept and design stages. We propose application of the Lee method, with several modifications, to the construction and renovation stages. The simplified Lee method is proposed and examined in the first two case studies. The simplified method limits the range and complexity of data inputs, and is intended to be an Lee used by engineers practicing in the construction industry. In the third case study, the "Lee per square-foot", which implements the concept of the "square-foot" cost estimating, is proposed. This method is intended to be used to assess the residual value and to estimate running costs of an existing building. Necessary modifications of the Lee, as well as the accuracy and limits of these new methods are examined through three case studies.

Assiste-se a um esforço crescente por parte de alguns países para a implementação do Life Cycle Costing na avaliação dos seus projetos de investimento por permitir antes da tomada de decisão a análise dos custos do ciclo de vida dos Sistema de Interesse em causa. Considerando que esta metodologia não está a ser aplicada na Força Aérea Portuguesa, importa proceder ao seu estudo, averiguar os impedimentos e propor soluções para que se possa converter o teoricismo em realidade. Neste trabalho são apresentadas, primeiramente, as questões que impedem a efetiva implementação do Life Cycle Costing na Força Aérea Portuguesa e são propostas soluções para as mesmas, tendo como ponto de partida a conceptualização prescrita pela OTAN. Em segundo lugar, com recurso a métodos empíricos (regras empíricas e opinião de especialistas) e de cálculo/ previsão (análise gráfica e de correlações) realizou-se uma primeira aplicação da metodologia ao Sistema de Armas F-16, tendo como base os dados recolhidos desde 2009 a 2017. Pelo estudo realizado pode concluir-se que a Força Aérea Portuguesa, com base na sua doutrina, procedimentos desenvolvidos e estrutura organizacional, se depara com alguns desafios para que seja possível uma aplicação sustentada e constante desta metodologia. Com este trabalho procura-se despertar o interesse da Força Aérea Portuguesa por esta metodologia, a qual permitirá prever os recursos que serão necessários no futuro com qualquer Sistema de Interesse, consubstanciando-se num instrumento de gestão capaz de fornecer informação útil, tanto para o planeamento, como para a tomada de decisão, particularmente a longo prazo.
There is a growing effort, by some countries, to implement Life Cycle Costing in the evaluation of their investment projects, by allowing the analysis of the life cycle costs of the relevant System of Interest. Considering that this methodology is not being applied in the Portuguese Air Force, it is necessary to study it, investigate impediments and propose solutions that can turn theory into reality. In this paper, we first present the issues that prevent the effective implementation of Life Cycle Costing in the Portuguese Air Force and propose solutions for them, starting with the conceptualization prescribed by NATO. Secondly, using the empirical methods (empirical rules and expert?s opinions) and calculation / forecasting (graphical and correlation analysis), the methodology is first applied to the F-16 Weapons System based on data collected from 2009 to 2017. Through the study carried out, it can be concluded that the Portuguese Air Force, based on its doctrine, developed procedures and organizational structure, faces some challenges so that a sustained and constant application of this methodology is possible. This work seeks to trigger the interest of the Portuguese Air Force in this methodology, which will allow to predict the resources that will be needed in the future with any system of interest, consubstantiating in a management tool capable of providing useful information, both for planning and for decision making, particularly in the long term.

Resumen
In the contemporary industry, companies need to make investments to grow their business volume. However each investment comes with its own risk. Cost of an equipment does not only consist of the initial payment but also covers the future costs related to the operations, maintenance, quality of production and many other associated issues. Therefore, economical analysis of an asset should be done by considering the whole life cycle. Life-Cycle Costing (LCC) can be used as an engineering tool in order to assess the future business risks and prevent the unexpected costs and losses due to failures and downtime before they occur. When first proposed as a proactive effort, LCC came into the industry with several advantages to be provided. However it could not keep pace with the modern industrial IT development.Automated machine tools constitute a crucial part of modern manufacturing activities. As an asset within the production layout, life-cycle of machine tools consists of several periods which are basically early design, purchase, installation, operation and disposal stages. Unfortunately, lack of a detailed cost analysis method drives most of the manufacturers to follow minimum adequate design (MAD) principle. As described above, decision process of investing in new equipments brings along the old famous debate: “Short-term spending or long-term benefits?”Recent studies have proven the fact that interruptions in production due to failures and maintenance account for a considerable part of not only production profit losses but also overhead costs. Regarding this problem, several new concepts in maintenance such as Reliability Centered Maintenance (RCM) and Condition Based Monitoring (CBM) have been developed. Main goal of these methods is to anticipate the failures which are likely to occur and keep the continuity of production. However, usage of these methods is still at very limited level since industry lacks a dynamic costing method that can justify the initial investment in production equipment assisted by such maintenance techniques. Although they are effective to some extent in calculating direct costs, traditional cost analysis methods usually fail in providing an accurate view on the indirect, consequential and overhead costs. On the other hand, by its2different point of view in handling indirect costs and their future impacts, LCC method can be a possible solution for this investment analysis problem.The objective of this study is to develop an LCC model that can assist the decision making process during the early stages of an investment. A dynamic LCC model which considers the maintenance aspect will be proposed and, as a specific case, this model will be used for estimating and optimizing the life-cycle costs of a CNC machining center based on its real-time technical data history.

Resumen

The purpose of this thesis is to develop a Life Cycle Cost model that could be used for investment, budgeting and comparing alternatives. An evaluation of existing models concluded that there was a need for a model that was easy to use and understand but in the same way economical and technical complex. Theoretical and empirical information was gathered in accordance with the purpose and made a base of the model. The model highlights operative, energy and maintenance costs. A case study to test the model has been carried out and selected company for this has been Swedwood International AB which is a part of IKEA. Swedwood currently works with pay back calculations which could lead to wrong decisions during the life length of the investment. The developed LCC model was tested on different techniques for applying an edge on a substrate. The result of the report is that the user will have a clear and structured overview of an investment during its economical life length. A final investment decision demands further tests and evaluations, for example technical test and MCDM. Further researches for the LCC model could be to investigate if the model lacks any critical aspects that should be included. A recommendation for Swedwood is to follow up the developed standards for collecting data at the factories in order to facilitate when investigating for new techniques and comparing between investment options.


Syftet med examensarbetet är att utveckla en livscykelkostnadsmodell som kan användas vid investeringar, budgeteringar och jämförelser. Efter en utvärdering av tillgängliga modeller konstaterades det att behov fanns för en modell som var ekonomisk och teknisk avancerad men ändå användarvänlig. Teori och empiri insamlades i enlighet med syftet och bildade en grund för modellen. Modellen belyser speciellt kostnadsaktiviteter så som operativa, energi och underhållskostnader. En fallstudie för att testa modellen har genomförts och fallföretaget var Swedwood International AB som är en del av IKEA. Swedwood arbetar nu med payback kalkyler vilket kan leda till fel beslut sett till hela investeringens livslängd. Den framtagna LCC modellen testades på olika tekniker för att applicera en kant på ett arbetstycke. Resultatet av rapporten är genom att använda modellen får man en klar och tydlig översikt av alla kostnader under en investerings ekonomiska livslängd. Ett investeringsbeslut kräver ytterligare tester och utvärderingar så som tekniska tester och MCDM. En fortsatt utveckling av modellen kan vara att undersöka om den saknar någon kritisk del som ska var inkluderad. En rekommendation till Swedwood är att följa upp de centralt utvecklade standarder på fabrikerna så att alla samlar in data på samma sätt, vilket skulle underlätta vid implementering av nya tekniker och vid jämförelser av investeringar.

Resumen
A well-maintained bridge infrastructure is a fundamental necessity for a modern society that provides great value, but ensuring that it meets all the requirements sustainably and cost-effectively is challenging. Bridge investment and management decisions generally involve selection from multiple alternatives. All of the options may meet the functional demands, but their life-cycle cost (LCC), service life-span, user-cost, aesthetic merit and environmental impact may differ substantially. Thus, life-cycle analysis (LCCA, a widely used decision-support technique that enables comparison of the LCC of possible options), is essential. However, although LCCA has recognized potential for rationalizing bridge procurement and management decisions its use in this context is far from systematic and the integration of LCCA findings in decisions is often far from robust. Thus, the overall objective of the work underlying this thesis has been to contribute to the development of sustainable bridge infrastructures while optimizing use of taxpayers’ money, by robustly incorporating life-cycle considerations into bridge investment and management decision-making processes. The work has introduced a full scheme for applying LCCA throughout bridges’ entire life-cycle. Several practical case studies have been presented to illustrate how an agency could benefit from use of a bridge management system (BMS) to support decisions related to the management of existing bridges and procure new bridges. Further developments include a comprehensive approach incorporating a novel LCCA technique, “LCC Added-Value Analysis”, which enables procurement of the most cost-efficient bridge design through a fair design-build (D-B) tendering process. A further contribution is a novel, holistic approach designed to enable procurement of bridges with the maximal possible sustainability (life-cycle advantages) under D-B contracts. The approach combines LCC Added-Value analysis with other techniques that make bridges’ aesthetic merit and environmental impact commensurable using an adapted concept named the willingness-to-pay-extra (WTPE). The systematic analytical procedures and potential of LCCA to deliver major savings highlighted in this thesis clearly demonstrate both the feasibility and need to integrate LCCA into bridge procurement and management decisions. This need has been recognized by Trafikverket (the Swedish Transport Administration), which has implemented a software tool developed in the research (BaTMan-LCC) in its bridge and tunnel management system (BaTMan). This thesis introduces readers to the field, considers BaTMan and the bridge stock in Sweden, discusses the developments outlined above and obstacles hindering further implementation of LCCA, then presents proposals for further advances.

Mit Blick auf die Anforderungen eines ELCC für PV besteht jedoch Nachholbedarf in der Verbindung und gemeinsamen Betrachtung von hot spots und trade offs aus ökologischer und ökonomischer Perspektive. Der definierte theoretische Rahmen für ein ELCC für PV, die kodierten Studien sowie das erstellte Inventar von Lebenszyklusanalysen der PV können nun als Grundlage für weitere Analysen dienen. Insbesondere eine inhaltliche Auswertung der konkreten Ergebnisse von Studien kann so einen Benchmark und Orientierung für neue Lebenszyklusanalysen für PV-Technologien liefern.
The special need of a sustainable energy supply in mind the technologies of the renewable source solar energy, especially photovoltaics (PV) is main subject of the present thesis. Using the inexhaustible, clean and “freely delievered” power from the sun solar devices may play a major role in a cleaner future, but, on the other hand, they are still energy consuming and expensive in their production which consequently demands a whole life cycle perspective when assessing this technology. For a closer look at PV the methodology of Environmental Life Cycle Costing (ELCC) is introduced by following three theoretical points of view. Namely these are sustainability, life cycle thinking and the three dimensional nature of this tool by regarding environmental, economic and technical aspects in their interaction. Based on theoretical elements of Life Cycle Assessment and Life Cycle Costing in combination with the technical background of photovoltaics main requirements and steps for performing an ELCC for PV are described. By executing software based content analysis the defined framework is checked (and modified) against a choice of 135 existing studies analyzing the life cycle of PV technologies from an environmental or economic perspective. As a result the main elements of an ELCC for PV, e.g. environmental impact categories and economic indicators, are identified (methodological feedback). Within the next step the existing studies are rated by their “quality” regarding the environmental, economic and more general parts of an ELCC for PV in order to create an inventory of life cycle studies for PV. This inventory is structured by technologies as well as quality of content respecting ELCC and might be used for further analyses. At this stage the results propose the possibility of a first estimate of the present status of ELCC for PV: until now there is a good pool of existing analyses of the life cycle of PV systems. But from an ELCC perspective the examination of common hot spots and trade offs between economic and environmental aspects should be expanded. The theoretical framework of ELCC for PV, the encoded studies and the inventory of life cycle analyses for PV are now the starting point for further analyses, especially of the individual outcome within studies, which will then pose a benchmark for new life cycle studies of PV technology.

Resumen
Traditionally when purchasing new products, the number one priority is to choose the conforming product with the lowest purchase cost. Companies procuring new equipment know that other expenses, such as those related to maintenance, are going to add significantly to the cost in the long run, but they are often unable to quantify these costs. For this reason they are limited to making the decisions solely on the initial purchase costs. Life Cycle Costing enables the purchaser to assess the products using the costs occurred over the entire life of the product. This paper discusses the benefits associated with the use of Life Cycle Costing (LCC) principles in the procurement of equipment. A LCC method for the acquisition of equipment is introduced. Included in this method is a freestanding computer program which calculates and produces results which aid in the analysis process.

Resumen
Obiettivo del presente elaborato è quello di offrire uno strumento di controllo orientato al tema della sostenibilità, in grado di prendere in considerazione la performance economico-ambientale relativa all’intero ciclo di vita di un prodotto, ed enfatizzare il suo utilizzo nel settore bio-edile. Lo studio analizzerà le performance di tre metodi costruttivi in legno dell’azienda Urban Green s.r.l., attraverso l’impiego delle metodologie Life Cycle Assessment, Life Cycle Cost ed Environmental Life Cycle Costing. L’LCA prenderà in riferimento esclusivamente gli impatti legati alle emissioni di CO2 (Carbon footprint), mentre l’LCC andrà a calcolare l’indicatore Net Present Cost. L’analisi ELCC studierà poi i costi legati all’esternalità (costi ambientali) e i costi economici sotto un’unica visione, al fine di generare un costo complessivo del ciclo di vita che prenda in considerazione sia l’aspetto economico che quello ambientale. In questo modo si potrà definire il progetto che richiede i costi minori, ossia il più performante dal punto di vista eco-efficiente ed individuare le fasi del ciclo di vita che necessitano di miglioramenti.

Resumen
In the past decades, while many countries planned and undertook more and bigger infrastructure megaprojects, poor performance has marred their delivery, for example through cost overruns, delays, disputes, and shortfalls in expected benefits. It is therefore important to improve performance levels, especially in infrastructure megaprojects that can considerablely influence the economy, society and environment. Project evaluation is an effective tool in project performance management as it provides stakeholders with a management process through which they can learn from the past and perform better in the future. Most of the traditional evaluation approaches emphasize the three basic success criteria of time, budget and quality. However, with the increasing importance of sustainability criteria and concerns, as well as the growing imperatives for stakeholder engagement, it has already been suggested to reconsider and redefine value by also evaluating other factors, such as those related to the environment and society. Therefore, an integrated whole life cycle value (WLCV) evaluation framework is proposed in order to improve infrastructure megaproject WLCV performance. In this study, whole life cycle (WLC) evaluation has a two-fold meaning: (i) the evaluation is based on a set of value factors drawn from a WLCV system; and (ii) this evaluation is a systematic continuous process from the start to the end of the project. However, considering the unique characteristics of every project, a totally fixed or static structure and content framework is neither sufficient nor suitable for the various types of infrastructure megaprojects. The recommended solution is to develop a semi-flexible framework that enables a pre-determined step by step dynamic structure formulation and a flexible WLCV system. In order to measure project WLCV derived from stakeholders’ expectations, from more objective and persuasive perspectives, the relevant value objectives/criteria/indicators, their weightings and targets will be identified, integrated and developed through this WLCV system. Cross-criteria relationships which have not been addressed adequately before, will be dealt with by assigning appropriate weightings. It is also proposed to build a database to store completed project information including various stakeholders’ expectations expressed in the form of value objectives. In order to develop the above proposed framework, a basic literature review was conducted to reveal and analyze the significant evaluation problems, identify trends in stakeholder engagement and develop the concept as well as typical criteria and indicators of project WLCV. Meanwhile evaluation practices, stakeholder engagement in the process of evaluation and WLCV perspectives in the Hong Kong construction industry were examined through a first round of interviews and the first of two focus group meetings. The first focus group meeting, second round interviews and the second focus group meeting were conducted to improve the proposed framework by investigating the importance of assigning an appropriate weighting to each value objective and each group of stakeholders; elaborating the various value criteria to measure value objectives at appropriate points of a project WLC. The findings from literature reviews, interviews, focus group meetings and a case study were integrated and injected into developing the aforementioned framework for building and administering the evaluation of project WLCV in ways that could improve desired project WLC performance. The outputs of the current research are expected to assist clients of infrastructure megaprojects to build a sense of ownership among all the key stakeholders at the outset, and to help motivate all stakeholders to be more co-operative, with a view to jointly targeting and monitoring an agreed project WLCV, thereby helping to achieve better WLC performance on infrastructure megaprojects. The main contributions to knowledge from this research are in developing a comprehensive evaluation methodology which combines and refines relevant components from existing evaluation approaches as well as injects the WLCV concept and criteria into a more holistic approach that is expected to identify and address current inadequacies in infrastructure megaproject delivery.

Resumen
Die vorliegende Ausgabe beschäftigt sich mit der systematischen Untersuchung potenzieller Einflussfaktoren auf die Lebenszykluskosten (LCC) von Abwasserpumpwerken. Betrachtungsobjekt ist eine Doppel-Tauchmotorpumpstation für den Einsatz in einer Trennkanalisation als Überpumpwerk für kommunales Schmutzwasser. Der zeitliche Betrachtungshorizont erstreckt sich über den gesamten Produktlebenszyklus. Primäres Ziel der Untersuchung ist die Identifizierung und Quantifizierung des Einflusses einzelner Systemparameter auf die Lebenszykluskosten. Aufgrund der Komplexität des betrachteten Systems kommt eine iterative Vorgehensweise zur Anwendung. Im ersten Iterationsschritt erfolgt eine separate Betrachtung des Systems aus technologischer, ökonomischer und ökologischer Sicht. Dabei werden aktuelle wissenschaftlich-theoretische Ansätze und Methoden auf ihre Anwendbarkeit auf die spezielle Problematik des Betrachtungsobjekts überprüft. Gemeinsam mit den Ergebnissen einer sich anschließenden System- und Umfeldanalyse stellen diese die Grundlage der separat entwickelten technischen, ökonomischen und ökologischen Einzelmodelle dar. In einer kritischen Würdigung werden diese drei Einzelmodelle auf Fehler, Schwächen und Stärken untersucht, um im zweiten Iterationsschritt in verbesserter Form zu einem integrierten technisch-ökonomisch-ökologischen Modell zusammengeführt zu werden. Mit Hilfe dieses Modells werden dann die zur Erreichung des Untersuchungsziels notwendigen, quantitativen Analysen (Sensitivitätsanalyse, Szenarioanalyse, Break-Even-Analyse, Payout-Analyse) des Betrachtungsobjekts durchgeführt. Die Analyseergebnisse werden ausgewertet und konkrete Handlungsempfehlungen abgeleitet, Forschungsbedarf wird aufgezeigt. Eine abschließende kritische Würdigung des Gesamtmodells soll zur weiteren Ver-besserungen der Modellierung in zukünftigen Untersuchungen anregen. Neben den quantitativen Analyseergebnissen ist das Gesamtmodell das wichtigste Ergebnis der Untersuchung, welches mit seiner softwaretechnischen Implementierung (Visual Basic 6.3 ? /MS Excel 2002?) ein Werkzeug liefert, das Entscheidungsträger sowohl auf strategischer als auch auf operativer Ebene unterstützen kann.

Resumen
Hydrogen fuel cell systems have many characteristics which are attractive for the heavyduty transport industry, including complementarity with electric vehicles and a cross-benefit from developments in batteries and electric drivetrains. Fuel cells may find their niche in the electrification of heavy-duty drivetrains, where zero emissions are desirable and where duty cycle or payload requirements exceed the capabilities of battery-only vehicles. Three hydrogen fuel cell buses (HFCBs) were trialled in Perth from 2004 to 2007. Life Cycle Assessment (LCA) and Life Cycle Cost (LCC) models were developed based on primary data. The LCA and LCC determine the overall environmental, energetic and economic performance of each technology by enumerating all phases of the complete transportation system including the fuel infrastructure, bus manufacturing, operation, and end-of-life disposal. LCA’s of the existing diesel and natural gas transportation systems were developed in parallel. In 2013 Transperth introduced a diesel-electric hybrid bus, which was incorporated in the study. International state-of-the-art HFCB data was also collected and modelled to determine the performance of a next-generation fleet in Perth. HFCB and Diesel-electric Hybrid technologies are compared to the baseline performance of the current Diesel bus fleet operating in Perth. The HFCB is modelled for several Australian hydrogen production pathways, and finds that electrolysis using grid electricity would increase emissions dramatically across all impact categories, while hydrogen from natural gas reforming provides a modest improvement. Electrolysis from wind dramatically reduces total emissions. The diesel-electric hybrid achieves a significant emissions reduction. However, the LCC finds that both the diesel-electric hybrid and the HFCB are far from costcompetitive with Diesel on a Total Cost of Ownership basis. An uncertainty analysis quantifies the potential LCA error, and several sensitivity analyses are used to understand the key factors that dominate the LCA and LCC outcomes, the breakeven points, and areas for further research.

Resumen
Els edificis d’energia neta poden ser entesos com a edificis, que durant un temps determinat generen tanta energia com consumeixen. Ja sigui des del punt de vista de l’oferta o el consum, la disponibilitat d’energia està relacionada amb alguns aspectes bàsics, com ara la font (s), la conversió, la distribució, l’ús, el malbaratament, l’optimització, l’eficiència i l’autonomia. Aquests temes revelen la complexitat del tema de l'energia i justifiquen l'atenció especial que li dóna la comunitat acadèmica. Per obtenir resultats tangibles en l'anàlisi d'aquests sistemes, en el nostre estudi ens centrem en la modelització i optimització de solucions energètiques aplicades a edificis o sistemes similars. D'altra banda, el període de temps dels objectes analitzats es va estendre fins al seu període de cicle de vida previst. Es van establir els objectius principals com: - Verificar i analitzar l’estat de la tecnologia de les energies renovables per a edificis i actius construïts i l’aplicabilitat de l’anàlisi de costos del cicle de vida a aquests temes; - Configurar models reproductibles d’edificis i les seves principals càrregues elèctriques, mitjançant eines d’enginyeria de processos assistits per ordinador, per procedir a simulacions i optimització, considerant-se com a font d’energia primària l’energia solar; - Quantificar, utilitzant estudis de casos reals i hipotètics, els beneficis de les solucions proposades, amb l'objectiu de realitzar tota l'avaluació de la sostenibilitat de la vida mitjançant la reducció de tot el cost del cicle de vida;
Los edificios de energía de red cero pueden entenderse como edificios, que durante un tiempo dado generan tanta energía como consumen. O bien, desde el punto de vista del suministro o el consumo, la disponibilidad de energía está relacionada con algunos problemas básicos, como las fuentes, la conversión, la distribución, la utilización, el desperdicio, la optimización, la eficiencia y la autonomía. Estos problemas revelan la complejidad del tema de la energía y justifican la atención especial que le presta la comunidad académica. Para obtener resultados tangibles en el análisis de estos sistemas, en nuestro estudio nos centramos en el modelado y la optimización de soluciones energéticas aplicadas a edificios o sistemas similares. Por otro lado, el período de tiempo de los objetos analizados se extendió a su período de ciclo de vida esperado. Los objetivos principales se establecieron como: - Verificar y analizar el estado de la técnica de las soluciones de energía renovable para edificios y activos construidos y la aplicabilidad del análisis de costos de ciclo de vida a estas cuestiones; - Configure modelos reproducibles de edificios y sus principales cargas eléctricas, a través de herramientas de Ingeniería de Procesos Asistidos por Computadora, para proceder a simulaciones y optimización, considerando como fuente de energía primaria la energía solar;
Net-zero energy buildings can be understood as buildings, that for a given time, generate as much energy as they consume. Either, from the point of view of supply or consumption, energy availability is related to some basic issues such as source (s), conversion, distribution, utilization, waste, optimization, efficiency and autonomy. These issues reveal the complexity of the subject of energy and justify the special attention given to it by the academic community. To obtain tangible results in the analysis of these systems, in our study we focus on the modelling and optimization of energy solutions applied to buildings or similar systems. On the other hand, the time frame of the analysed objects was extended to their expected life cycle period. The main objectives were stablished as: - Verify and analyse the state-of-the-art of renewable energy solutions for buildings and constructed assets and the applicability of life cycle costing analysis to these issues; - Configure reproducible models of buildings and their main electrical loads, via Computer Aided Process Engineering tools, to proceed simulations and optimization, considering as primary energy source solar energy; - Quantify, using real-life and hypothetical case studies, the benefits of the proposed solutions, aiming the whole life sustainability assessment through the reduction of the whole life cycle costing; and - Guarantee the reproducibility of the models and main general results of this study and make them public, to contribute with their applicability and further researches.

Resumen
Investments in power systems are characterized by large investment costs and uncertainties doto extended time frame. New consumption patterns in the electricity grid, as well as an aginggrid calls for modernization, new solutions and new investments. Components in the electricalsystem is characterized by most of their costs that are caused after their acquisition. One stateof the art method in analyzing investments over long time frames and provide long-term costestimation is life cycle costing (LCC). In LCC a "cradle to grave"-approach is performed whichenables comparative cost assessment to be made. This thesis reviews the existing literature inprobabilistic life cycle costing and gives a step by step methodology for DSOs to systematicallyaddress uncertainty in cost and technical parameters.This thesis proposes a Monte Carlo sampling method in combination with a Markov Chainfailure model to model failures is providing a comprehensive method of reaching nancial benetwhen comparing dierent investment decisions. The model evaluates nancial implications andtechnical properties to demonstrate the total cost of components. This thesis analyses a casefor Swedish distribution system operators and their investment in transformers. The proposedmodel includes an all-covering model of costs and incentives. The main conclusion is that probabilisticlife cycle costing benets investment decisions and the applied method shows promisingresults in addressing uncertainty and investment risks. The developed PLCC model is used onan investment decision where two transformers are compared. Results shows that PLCC is apowerful tool and could be used in power system applications.
Investeringar i kraftsystem kännetecknas av höga investeringskostnader och osäkerheter på grundav komponenternas långa livslängd. Nya konsumtionsönster och ett föråldrat elsystem efterfrågar mordenisering, nya lösningar och nya investeringar. Komponenter i elnätet karakteriserasav att den största delen av kostnader orsakas efter de förvärvats. En framstående metod för attanalysera investeringar som löper över långa tidsspann och som kan ge en kostnadsestimeringär livscykelkostnadsanalys. Inom livscykelkostnadsanalys tillämpas ett från vaggan till graventillvägagångssätt vilket möjliggör jämförelser av kostnader. Denna uppsats granskar existerandeforskning inom probabilistisk livscykelanalys och ger en steg-för-steg-metodik för att en distributionsnätsoperatör systematiskt skall kunna adressera osäkerheter relaterade till kostnader samttekniska parametrar.Denna uppsatsen föreslår en Monte Carlo-metod i kombination av en Markovkedja, för attmed en heltäckande metod nå finansiell jämförbarhet mellan olika investeringsbeslut. Denna uppsatsenanalyserar ett fall för en svensk distributionsnätsoperatör och dess investering i transformatorer.Den föreslagna modellen inkluderar en heltäckande modell för kostnader och incitamet.Huvudresultatet från den föreslagna metoden är att probabilistisk livscykelkostnadsanalys samtde använda metoderna visar lovande resultat för att adressera osäkerheter och risker vid investeringsbeslut.
