Planeamento estratégico através da implementação da metodologia Balanced Scorecard numa empresa de construção

Atualmente, existe uma constante necessidade de inovação tecnológica e organizacional das empresas, face às exigências do mercado e ao aumento constante da competitividade. No contexto da economia atual, e para contrariar a falta de investimento dos últimos anos, as empresas concentram-se no desenvolvimento de negócios bem estruturados e organizados, que satisfaçam as exigências de cada cliente. Revela-se, assim, muito importante a avaliação de desempenho para o alcance do seu sucesso, permitindo alinhar as atividades operacionais com a visão organizacional, fomentar a comunicação da estratégia e gerir o seu desempenho. É neste contexto que ganha importância o Balanced Scorecard, um instrumento que permite avaliar o desempenho organizacional, funcionando também como uma ferramenta de gestão. Tem, portanto, como principais objetivos definir claramente uma estratégia, definir objetivos, indicadores e medidas estratégicas, planear e estabelecer metas e melhorar continuamente os resultados obtidos. Esta ferramenta analisa a organização em quatro diferentes perspetivas: financeira, clientes, processos internos e apendizagem e crescimento. Cada uma delas deve estrututrar os seus próprios objetivos, indicadores, metas e iniciativas de forma a contribuir para o desenvolvimento da estratégia da organização e avaliar o seu desempenho. O desafio deste relatório é adaptar esta metodologia durante a realização de um estágio curricular na empresa Bysteel, que tem por base a implementação de um processo de gestão estratégica nas suas empreitadas, através do Balanced Scorecard. Este planemamento surge como um dos principais requisitos para uma gestão eficaz de custos e de tempo planeados para cada empreitada da Bysteel. Este processo torna-se bastante complexo dado que cada obra apresenta diferentes particularidades. A implementação desta metodologia numa empresa desta dimensão é um fator muito motivador, tornando-se ainda mais interessante pelo facto de se tratar de uma implementação numa nova vertente.

O acordo de Basileia II

Este trabalho evidencia a gestão do risco operacional e a importância da implementação de uma estrutura adequada de gestão de risco. De forma a contextualizar o tema foi abordado o conceito de risco e risco operacional e as várias categorias de risco e feito o enquadramento nos vários Acordos de Basileia. Enfocou-se em Basileia II que inovou tratando do risco operacional, até então esquecido. Neste ambito foram abordados os vários métodos de avaliação de risco: basico, standard e avançado. A temática está organizada de forma a que haja um fio condutor que culmina na gestão do risco apresentando as linhas orientadoras do BIS a esse respeito e um modelo de uma estrutura de gestão de risco. Por fim o exemplo do Banco Comercial Português que implementou a sua estrutura de gestão de risco tendo em conta as diretrizes de Basileia considerando métodos benchmark de gestão de risco.

Distributed energy resources management with cyber-physical SCADA in the context of future smart grids

In the energy management of a small power system, the scheduling of the generation units is a crucial problem for which adequate methodologies can maximize the performance of the energy supply. This paper proposes an innovative methodology for distributed energy resources management. The optimal operation of distributed generation, demand response and storage resources is formulated as a mixed-integer linear programming model (MILP) and solved by a deterministic optimization technique CPLEX-based implemented in General Algebraic Modeling Systems (GAMS). The paper deals with a vision for the grids of the future, focusing on conceptual and operational aspects of electrical grids characterized by an intensive penetration of DG, in the scope of competitive environments and using artificial intelligence methodologies to attain the envisaged goals. These concepts are implemented in a computational framework which includes both grid and market simulation.

RadiaLE: A framework for designing and assessing link quality estimators in wireless sensor networks

Stringent cost and energy constraints impose the use of low-cost and low-power radio transceivers in large-scale wireless sensor networks (WSNs). This fact, together with the harsh characteristics of the physical environment, requires a rigorous WSN design. Mechanisms for WSN deployment and topology control, MAC and routing, resource and mobility management, greatly depend on reliable link quality estimators (LQEs). This paper describes the RadiaLE framework, which enables the experimental assessment, design and optimization of LQEs. RadiaLE comprises (i) the hardware components of the WSN testbed and (ii) a software tool for setting-up and controlling the experiments, automating link measurements gathering through packets-statistics collection, and analyzing the collected data, allowing for LQEs evaluation. We also propose a methodology that allows (i) to properly set different types of links and different types of traffic, (ii) to collect rich link measurements, and (iii) to validate LQEs using a holistic and unified approach. To demonstrate the validity and usefulness of RadiaLE, we present two case studies: the characterization of low-power links and a comparison between six representative LQEs. We also extend the second study for evaluating the accuracy of the TOSSIM 2 channel model.

Space-time monitoring of prescribed burnt soils performance – an effective tool for forest management

Among the most important measures to prevent wild forest fires is the use of prescribed and controlled burning actions in order to reduce the availability of fuel mass. However, the impact of these activities on soil physical and chemical properties varies according to the type of both soil and vegetation and is not fully understood. Therefore, soil monitoring campaigns are often used to measure these impacts. In this paper we have successfully used three statistical data treatments - the Kolmogorov-Smirnov test followed by the ANOVA and the Kruskall-Wallis tests – to investigate the variability among the soil pH, soil moisture, soil organic matter and soil iron variables for different monitoring times and sampling procedures.

Management Driven Hybrid Multicast Framework for Content Aware Networks

The need for better adaptation of networks to transported flows has led to research on new approaches such as content aware networks and network aware applications. In parallel, recent developments of multimedia and content oriented services and applications such as IPTV, video streaming, video on demand, and Internet TV reinforced interest in multicast technologies. IP multicast has not been widely deployed due to interdomain and QoS support problems; therefore, alternative solutions have been investigated. This article proposes a management driven hybrid multicast solution that is multi-domain and media oriented, and combines overlay multicast, IP multicast, and P2P. The architecture is developed in a content aware network and network aware application environment, based on light network virtualization. The multicast trees can be seen as parallel virtual content aware networks, spanning a single or multiple IP domains, customized to the type of content to be transported while fulfilling the quality of service requirements of the service provider.

Knowledge management in higher education institutions: a framework to improve collaboration

The purpose of this paper is to present a framework that increases knowledge sharing and collaboration in Higher Education Institutions. The paper discusses the concept of knowledge management in higher education institutions, presenting a systematization of knowledge practices and tools to linking people (students, teachers, researchers, secretariat staff, external entities)and promoting the knowledge sharing across several key processes and services in a higher education institution, such as: the research processes, learning processes, student and alumni services, administrative services and processes, and strategic planning and management. The framework purposed in this paper aims to improve knowledge practices and processes which facilitate an environment and a culture of knowledge collaboration,sharing and discovery that should characterize an institution of higher education.

An organizational culture approach to performance in information technology micro-firms

This study aims to analyze and compare micro-firms’ organizational culture related to organizational performance. A case study methodology was used based on four firms, competitors among themselves in the Information Technology business, focusing on the years between 2008-2013. Findings pointed out many similarities to larger firms, but some specificities of micro-firms were found and propositions were defined: clan culture predominance is related to best performing micro-firms; the configuration of several culture types seemed to be the most suitable for obtaining good organizational results, provided that they do not focus only on hierarchy and market types of culture; the market culture predominance perception by employees is associated with low job satisfaction; and, after a certain time in business, micro-firms, as do larger companies, seek to standardize and control processes. Recognizing that organizational culture is considered important to firms’ results, this study sheds some light on that important factor for micro-firms.
