Traditional approaches to evaluate performance in hotels, have mainly used financial measures. Building on Speckbacher et al. (2003), this Work Project aims to design and propose a Balanced Scorecard Type II as a performance measurement/management system for the hospitality industry based on data collected at the Luxury Brand Hotels of Pestana Group. The main contribution is to better align the vision, strategy and financial and non-financial performance measures in this category of hotels, in particular those of Pestana Group, and by doing so, lead their managers to focus on what is really critical and, consequently improve the overall performance.

In developed countries, civil infrastructures are one of the most significant investments of governments, corporations, and individuals. Among these, transportation infrastructures, including highways, bridges, airports, and ports, are of huge importance, both economical and social. Most developed countries have built a fairly complete network of highways to fit their needs. As a result, the required investment in building new highways has diminished during the last decade, and should be further reduced in the following years. On the other hand, significant structural deteriorations have been detected in transportation networks, and a huge investment is necessary to keep these infrastructures safe and serviceable. Due to the significant importance of bridges in the serviceability of highway networks, maintenance of these structures plays a major role. In this paper, recent progress in probabilistic maintenance and optimization strategies for deteriorating civil infrastructures with emphasis on bridges is summarized. A novel model including interaction between structural safety analysis,through the safety index, and visual inspections and non destructive tests, through the condition index, is presented. Single objective optimization techniques leading to maintenance strategies associated with minimum expected cumulative cost and acceptable levels of condition and safety are presented. Furthermore, multi-objective optimization is used to simultaneously consider several performance indicators such as safety, condition, and cumulative cost. Realistic examples of the application of some of these techniques and strategies are also presented.

RESUMO - O presente trabalho aborda a temática da avaliação de desempenho do ponto de vista dos vários intervenientes no sistema de saúde português. Propõe a criação de indicadores de desempenho para um sistema nacional, em que cada patamar tem o seu próprio modelo definido. Estes modelos de organização dos dados são uma forma de concatenar dois dos modelos mais utilizados, o painel de controlo de gestão e o balanced scorecard. Os dados esperados pelo autor levam a concluir pela inexistência de um sistema tal como o proposto. No entanto alguns dos dados existentes são suficientes para iniciar um processo futuro de análise a partir deste trabalho de projecto. -----------------------ABSTRACT - The present essay focuses on the evaluation of performance from the point of view of all the managers in the Portuguese healthcare system. It proposes the creation of performance indicators in every stage of the healthcare system. The way this is done is by linking together two of the most used models in the world, the tableaux de board and the balanced scorecard. The author is lead to conclude that given the availability of data in Portugal such a model does not exist. However given that some data is available it is possible to initiate a process of future analysis taking the present essay into account.

This work aims to identify and rank a set of Lean and Green practices and supply chain performance measures on which managers should focus to achieve competitiveness and improve the performance of automotive supply chains. The identification of the contextual relationships among the suggested practices and measures, was performed through literature review. Their ranking was done by interviews with professionals from the automotive industry and academics with wide knowledge on the subject. The methodology of interpretive structural modelling (ISM) is a useful methodology to identify inter relationships among Lean and Green practices and supply chain performance measures and to support the evaluation of automotive supply chain performance. Using the ISM methodology, the variables under study were clustered according to their driving power and dependence power. The ISM methodology was proposed to be used in this work. The model intends to provide a better understanding of the variables that have more influence (driving variables), the others and those which are most influenced (dependent variables) by others. The information provided by this model is strategic for managers who can use it to identify which variables they should focus on in order to have competitive supply chains.

Unilever Jerónimo Martins is a Portuguese joint-venture leading firm in what concerns the supply chain industry of fast-moving consumer goods in Portugal. The scope of analysis of this Work Project is focusing on Unilever-JM operations and services in the Portuguese market regarding quality, efficiency and effectiveness over B2B customers. It will be analysed the possibility of development and implementation of a performance measurement system, Tableau de Bord, which will be crucial for the identification of potential opportunities of improvement with impact in the supply chain processes. This will be completed through the establishment of KPI’s to monitor and manage periodically logistics, planning and customer service processes’ performance, which are the ones where the bottlenecks are impacting more in the supply chain. In this work project the nexus causality for the problems will also be discussed and some recommendations will be prepared to tackle the inefficiencies found through the monitoring of the previous core processes, in order to improve efficacy and quality service of the supply chain.

NAV Portugal is the Air Navigation Service Provider in Portugal, providing air traffic control services in the airspace under the country’s responsibility. Recently, the company has been included in an initiative launched by the European Commission, called the Single European Sky. This aims for a unification of the European airspace, improving it in four main pillars: safety, capacity, environment, and cost-efficiency. To each of them, Key Performance Indicators need to be computed and monitored, all having pre-defined targets. The presented work project will be analyzing how NAV Portugal is doing in the pillar of capacity, proving suggestions if needed.

RESUMO - Introdução: Os modelos organizacionais de saúde baseados na gestão integrada de cuidados têm permitido melhorar os resultados em saúde. A taxa de readmissão hospitalar (um indicador de resultados) tem diminuído nas instituições que adotaram aquele modelo de gestão. Em Portugal, a criação das Unidades Locais de Saúde, representa a adoção de um modelo baseado na gestão integrada entre os cuidados de saúde hospitalares, primários e continuados, pelo que importa comparar a taxa de readmissões hospitalares entre os hospitais com esse modelo e os restantes Hospitais. Metodologia: Determinaram-se as readmissões não planeadas a 30 dias nos hospitais públicos portugueses do Continente durante 2013, segundo a metodologia do Centers for Medicare and Medicaid Service, que usa um algoritmo que identifica as readmissões que são habitualmente planeadas e podem ocorrer no prazo de 30 dias após a alta hospitalar. Foi calculada a taxa anual de readmissão por tipo de hospital e a sua frequência por género, faixa etária e para indivíduos com insuficiência cardíaca, doença pulmonar obstrutiva crónica, diabetes mellitus e hipertensão arterial. Resultados: Dos 692.211 episódios de internamento de 2013, 6,0% corresponderam a readmissões hospitalares não planeadas a 30 dias. Os episódios de internamento nas Unidades Locais de Saúde foram 72.725, sendo 6,6% readmitidos. Nos restantes Hospitais foram 619.486, sendo 6,0% readmitidos. A taxa de readmissão registada nos indivíduos do sexo masculino foi superior à do sexo feminino nas Unidades Locais de Saúde (7,6% vs. 6,0%) e nos restantes Hospitais (6,7% vs. 5,4%), não sendo esta diferença estatisticamente significativa (p> 0,05). Foram identificadas diferenças estatisticamente significativas (p <0,05) nas taxas de readmissão por faixa etária, sendo as pessoas com 65 anos ou mais as que apresentaram a maior taxa de readmissão nas Unidades Locais de Saúde (10,3%) e nos restantes Hospitais (10,0%). Quando analisadas as readmissões por patologia, nas Unidades Locais de Saúde os doentes com doença pulmonar obstrutiva crónica foram os que apresentaram a maior taxa de readmissão (17,5%) e os doentes com insuficiência cardíaca os que apresentaram a maior taxa de readmissão para os restantes Hospitais (16,4%). Conclusão: Em termos gerais, a frequência das readmissões nas Unidades Locais de Saúde é superior à dos restantes Hospitais. Os resultados obtidos podem indicar dificuldades na operacionalização do modelo de gestão adotado pelas Unidades Locais de Saúde, nomeadamente falhas na coordenação dos cuidados entre os diferentes níveis de prestação de cuidados.
