Currently, many researchers and stakeholders believe that effective delivery systems for construction projects are key to improving project quality and value in the construction industry. Therefore, it is important that owners use the best project delivery system because there are significant consequence due to differences in contracting processes and roles and responsibilities among contracting parties. For the reason, this research aims to compare the efficiency of DB with that of CMAR, as two methods used to select or deny expectations, specifically through quantitative and qualitative analysis. In order to do that, the researcher identified performance data and benefits, drawbacks, and success factors of DB and CMAR through survey and case projects and also analyzed performance data collected from two case projects. Consequently, owners will be able to understand characteristics, differences, and success factors of two different PDSs based on the comparative study. Furthermore, this research could be used to develop a decision support system for owners to select an appropriate PDS.

In this thesis, COTS-software requirements elicitation, which is an input for RFP in software intensive automation system&rsquo / s acquisition, is examined. Business Process Models are used for COTS-software requirements elicitation. A new method, namely CREB, is developed to meet the requirements of COTS-software. A software intensive system acquisition of a military organization is used to validate the method.

In the construction industry, there are various methods for how the client and contractor should work together. Historically, most contracts have been awarded through traditional cooperation, resulting in limited collaboration between the contractor and the client. In recent times, partnering has become increasingly common, based on close collaboration between the client and the contractor. As partnering has gained popularity, the profitability of different collaboration forms has come under scrutiny, as well as which collaboration form contributes to the highest quality of the final product and the lowest cost for the client. The purpose of this work is to examine how incentives and competition will affect the different parties’ approach to risk management within the different collaboration forms. This will be done through three different methods: a literature study, a case study, and interviews, clearly demonstrating how risk management varies depending on the collaboration form applied in the project. The literature study forms the basis for the analysis of the case study and the formulation of the questions asked in the interviews. The case study compares the risk and opportunity assessments of two ongoing construction projects, one using traditional cooperation and the other using partnering. The interview study is based on seven interviews with relevant respondents, each offering their perspective on the collaboration forms. The work shows that incentives and competition will influence the parties eagerness to work with risk management to the extent that it is profitable. Since many partnering agreements have somewhat loose reins, it means that the client must take on greater responsibility for a partnering project to become profitable. The work also highlights that competition will have a significant impact on the contractor's risk allocations depending on the collaboration form applied in the project.

Os Procedimentos de Manifestação de Interesse (PMI) e Propostas Não Solicitadas (PNS) são mecanismos para a viabilização de projetos de Parcerias Público-Privadas (PPP/PFIs). Contudo, a ausência de critérios claros para avaliação e priorização de parceiros, de forma transparente e técnica, leva à seleção adversa de propostas, contribuindo para o insucesso dos projetos. O principal instrumento utilizado na avaliação PPP/PFIs é uma análise quantitativa baseada no Value For Money (VfM). O propósito deste trabalho foi investigar os problemas relacionados com os processos de avaliação das propostas dos PMI submetidas aos órgãos demandantes dos serviços. Iniciou-se com a análise do Fatores Críticos para o Sucesso (FCSs) das PPP/PFIs, dos PMI e PNS, identificadas na literatura. Os Fatores Críticos foram apresentados a um conjunto de 78 especialistas que responderam também sobre a processo de análise das propostas. No questionário os autores foram confrontados também com as propriedades da visão. O resultado indica que a análise com o VfM seria incompleta e insuficiente para capturar a complexidade do escopo destes projetos. A pesquisa possibilitou ainda organizar os fatores críticos em 7 dimensões a serem consideradas na avaliação destes projetos. Essas dimensões podem ser utilizadas para a criação de instrumentos de avaliação e um exemplo foi proposto, um indicador nomeado de índice \"T\", avaliado por um grupo de 12 especialistas em projetos de PPP/PFIs. A pesquisa contribui, portanto, para apoiar a criação de instrumentos de avaliação de PPP/PFIs que considerem uma análise mais ampla, considerando aspectos qualitativos e quantitativos. / Unsolicited Proposals (UNPs) are one of the main mechanisms for verifying the feasibility of Public-Private Partnerships (PPP/PFIs/PFIs) projects. However, the lack of clear criteria to evaluate and to prioritize the partner, in a transparent and technical way, has led to adverse selection of proposals increasing the level of failure of these projects. The main instrument used in the PPP/PFIs evaluation is a quantitative analysis based on Value for Money. The purpose of this research was to investigate the problems related with the processes of evaluation of the Unsolicited Proposals (UNPs) that are submitted to the respective government offices. The study compiles the analysis of Critical Success Factors (CSFs) for Public-Private Partnerships (PPP/PFI) and the Unsolicited Proposals (UNPs), identified in the literature, and synthetized by the evaluation of a group of 78 specialists, resulting in the organization of 7 (seven) dimensions to be considered in the evaluation of these projects. This study also demonstrated that, according to these experts, the analysis with VfM would be incomplete and insufficient to capture the complexity of the scope of these projects. As an alternative a set of 7 (seven) indicators where created related to each dimension and a general index that synthetize the performance in the dimensions, considering qualitative and quantitative aspects. The index was labeled as \"T\" index and evaluated by a group of 12 (twelve) experts on PPP/PFI projects. The results from the analyses indicate that the index allows a linear comparative analysis between the proposals received by the public entity requesting the Public- Private Partnership (PPP/PFI) services. The model of indicators decreases the subjectivity of the choices made by public managers, resulting in greater transparency for the process of proposal qualification and security to the market.

A formal framework is developed and implemented in this research for preliminary rotorcraft design using IPPD methodology. All the technical aspects of design are considered including the vehicle engineering, dynamic analysis, stability and control, aerodynamic performance, propulsion, transmission design, weight and balance, noise analysis and economic analysis. The design loop starts with a detailed analysis of requirements. A baseline is selected and upgrade targets are identified depending on the mission requirements. An Overall Evaluation Criterion (OEC) is developed that is used to measure the goodness of the design or to compare the design with competitors. The requirements analysis and baseline upgrade targets lead to the initial sizing and performance estimation of the new design. The digital information is then passed to disciplinary experts. This is where the detailed disciplinary analyses are performed. Information is transferred from one discipline to another as the design loop is iterated. To coordinate all the disciplines in the product development cycle, Multidisciplinary Design Optimization (MDO) techniques e.g. All At Once (AAO) and Collaborative Optimization (CO) are suggested. The methodology is implemented on a Light Turbine Training Helicopter (LTTH) design. Detailed disciplinary analyses are integrated through a common platform for efficient and centralized transfer of design information from one discipline to another in a collaborative manner. Several disciplinary and system level optimization problems are solved. After all the constraints of a multidisciplinary problem have been satisfied and an optimal design has been obtained, it is compared with the initial baseline, using the earlier developed OEC, to measure the level of improvement achieved. Finally a digital preliminary design is proposed. The proposed design methodology provides an automated design framework, facilitates parallel design by removing disciplinary interdependency, current and updated information is made available to all disciplines at all times of the design through a central collaborative repository, overall design time is reduced and an optimized design is achieved.
