Utilization of Quality Tools: does sector and size matter?

This research focuses on the influence of company sector and size on the level of utilization of Basic and Advanced Quality Tools. The paper starts with a literature review and then presents the methodology used for the survey. Based on the responses from 202 managers of Portuguese ISO 9001:2008 Quality Management System certified organizations, statistical tests were performed. Results show, with 95% confidence level, that industry and services have a similar proportion of use of Basic and Advanced Quality Tools. Concerning size, bigger companies show a higher trend to use Advanced Quality Tools than smaller ones. For Basic Quality Tools, there was no statistical significant difference at a 95% confidence level for different company sizes. The three basic Quality tools with higher utilization were Check sheets, Flow charts and Histograms (for Services) or Control Charts/ (for Industry), however 22% of the surveyed organizations reported not using Basic Quality Tools, which highlights a major improvement opportunity for these companies. Additional studies addressing motivations, benefits and barriers for Quality Tools application should be undertaken for further validation and understanding of these results.

Orchestration of e-learning services for automatic evaluation of programming exercises

Managing programming exercises require several heterogeneous systems such as evaluation engines, learning objects repositories and exercise resolution environments. The coordination of networks of such disparate systems is rather complex. These tools would be too specific to incorporate in an e-Learning platform. Even if they could be provided as pluggable components, the burden of maintaining them would be prohibitive to institutions with few courses in those domains. This work presents a standard based approach for the coordination of a network of e-Learning systems participating on the automatic evaluation of programming exercises. The proposed approach uses a pivot component to orchestrate the interaction among all the systems using communication standards. This approach was validated through its effective use on classroom and we present some preliminary results.

A case study on the eco-efficiency performance of a composite processing industry: evaluation and quantification of potential improvements

In this study, an attempt was made in order to measure and evaluate the eco-efficiency performance of a pultruded composite processing company. For this purpose the recommendations of World Business Council for Sustainable Development (WCSD) and the directives of ISO 14301 standard were followed and applied. The main general indicators of eco-efficiency, as well as the specific indicators, were defined and determined. With basis on indicators’ figures, the value profile, the environmental profile, and the pertinent eco-efficiency ratios were established and analyzed. In order to evaluate potential improvements on company eco-performance, new indicators values and eco-efficiency ratios were estimated taking into account the implementation of new proceedings and procedures, at both upstream and downstream of the production process, namely: i) Adoption of a new heating system for pultrusion die-tool in the manufacturing process, more effective and with minor heat losses; ii) Recycling approach, with partial waste reuse of scrap material derived from manufacturing, cutting and assembly processes of GFRP profiles. These features lead to significant improvements on the sequent assessed eco-efficiency ratios of the present case study, yielding to a more sustainable product and manufacturing process of pultruded GFRP profiles.

A Quantitative Model for Decomposing & Assessing the Value for the Customer

The research presented in this paper proposes a novel quantitative model for decomposing and assessing the Value for the Customer. The proposed approach builds on the different dimensions of the Value Network analysis proposed by Verna Allee having as background the concept of Value for the Customer proposed by Woodall. In this context, the Value for the Customer is modelled as a relationship established between the exchanged deliverables and a combination of tangible and intangible assets projected into their endogenous or exogenous dimensions. The Value Network Analysis of the deliverables exchange enables an in-depth understanding of this frontier and the implicit modelling of co-creation scenarios. The proposed Conceptual Model for Decomposing Value for the Customer combines several concepts: from the marketing area we have the concept of Value for the Customer; from the area of intellectual capital the concept of Value Network Analysis; from the collaborative networks area we have the perspective of the enterprise life cycle and the endogenous and exogenous perspectives; at last, the proposed model is supported by a mathematical formal description that stems from the area of Multi-Criteria Decision Making. The whole concept is illustrated in the context of a case study of an enterprise in the footwear industry (Pontechem). The merits of this approach seem evident from the contact with Pontechem as it provides a structured approach for the enterprises to assess the adequacy of their value proposition to the client/customer needs and how these relate to their endogenous and/or exogenous tangible or intangible assets. The proposed model, as a tool, may therefore be a useful instrument in supporting the commercialisation of new products and/or services.

Mergers and acquisitions as strategies of business expansion in the pharmaceutical industry

Introduction: The present paper deals with the issue of the increasing usage of corporation mergers and acquisitions strategies within pharmaceutical industry environment. The aim is to identify the triggers of such business phenomenon and the immediate impact on the financial outcome of two powerful biopharmaceutical corporations: Pfizer and GlaxoSmithKline, which have been sampled due to their successful approach of the tactics in question. Materials and Methods: In order to create an overview of the development steps through mergers and acquisitions, the historical data of the two corporations has been consulted, from their official websites. The most relevant events were then associated with adequate information from the financial reports and statements of the two corporations indulged by web-based financial data providers. Results and Discussions: In the past few decades Pfizer and GlaxoSmithKline have purchased or merged with various companies in order to monopolize new markets, diversify products and services portfolios, survive and surpass competitors. The consequences proved to be positive although this approach implies certain capital availability. Conclusions: Results reveal the fact that, as far as the two sampled companies are concerned, acquisitions and mergers are reactions at the pressure of the highly competitive environment. Moreover, the continuous diversification of the market’s needs is also a consistent motive. However, the prevalence and the eminence of mergers and acquisition strategies are conditioned by the tender offer, the announcer’s caliber, research and development status and further other factors determined by the internal and external actors of the market.

O presente trabalho insere-se no âmbito do Mestrado de Engenharia Química, ramo Optimização Energética na Indústria Química e pretende-se efectuar a avaliação energética do Complexo Municipal de Piscinas de Folgosa, localizado no Concelho da Maia, tendo como principais bases os Decretos-Lei 78, 79 e 80 de 04 de Abril 2006. Uma vez que a área útil de pavimento do presente edifício é superior a 1000 m2, encontra-se englobado no conceito de Grande Edifício de Serviços (GES). A escolha do Complexo Municipal de Piscinas de Folgosa para a realização do presente estudo prendeu-se com o facto de ser um objectivo da Câmara Municipal, mais concretamente do Departamento de Conservação e Manutenção de Estruturas Municipais, dar inicio aos procedimentos necessários para a certificação energética dos diversos edifícios Municipais, aliado ao facto das piscinas serem um tipo de edifício desportivo de elevada complexidade em termos de gestão, um grande consumidor de energia e possuidor de uma elevada diversidade de equipamentos. O objectivo principal será o de caracterizar energeticamente o edifício e optimizar os consumos do mesmo, de forma a reduzir, não só os consumos energéticos e respectiva factura, mas também nas emissões dos gases de efeito de estufa (CO2), pelo que a ordem de trabalhos inclui a realização de: - Avaliação Energética de acordo com o n.º1 do artigo 2º e artigo 34º do D. L. 79/2006; - Verificação dos Requisitos de Condução e manutenção das instalações de Aquecimento, Ventilação e Ar Condicionado (AVAC); - Caracterização Energética do Edifício – Índice de Eficiência Energética. A metodologia seguida baseou-se na utilizada para a realização de uma auditoria energética, sendo que foram contempladas as seguintes etapas: estudo pormenorizado da legislação referente à certificação de edifícios; realização de um levantamento de consumos energéticos reais da instalação (com base nas facturas energéticas); das suas características funcionais e levantamento dos vários equipamentos consumidores de energia. O Complexo Municipal de Piscinas de Folgosa é uma instalação cuja média de consumo de energia eléctrica nos últimos três anos foi de 445969 kWh/ano e de 87300 m3 de gás natural, representando um consumo global de energia primária de 174,85 tep/ano. De acordo com o Sistema de Certificação Energética o Índice de Eficiência Energética determinado é de 54,50 kgep/m2 .ano. Uma vez que o IEE determinado é superior ao valor de IEEReferência existentes, o edifício estará obrigado ao cumprimento de um Plano de Racionalização Energética (PRE). É apresentado um conjunto de medidas que visam uma redução do consumo de energia do edifício e consequentemente uma melhoria no Índice de Eficiência Energética.

Position paper on time and event-triggered communication services in the context of e-manufacturing

Modern factories are complex systems where advances in networking and information technologies are opening new ways towards higher efficiency. Such move is being driven by market rules with ever-increasing competition levels, in search for faster time-to-market, improved process yield, non-stop operations, flexible manufacturing and tighter supply-chain coupling. All these aims present a common requirement, i.e. a realtime flow of information, from the plant-floor up to the management, maintenance, suppliers and clients, to support accurate monitoring and control of the factory. This stresses the importance achieved by the communication infrastructure in modern manufacturing industry. This paper presents the authors view concerning the current trends in modern factory communication systems. It addresses the problems of seamlessly integrating different information flows with diverse requirements, mainly in terms of timeliness. In this aspect, the debate between event-triggered and time-triggered communication is revisited as well as the joint support for both types of traffic. Finally, a view of where factory communication systems are moving to is also presented, showing the impact of open and widely available technologies.

Evaluation of a real time DGPS data server

The goal of the this paper is to show that the DGPS data Internet service we designed and developed provides campus-wide real time access to Differential GPS (DGPS) data and, thus, supports precise outdoor navigation. First we describe the developed distributed system in terms of architecture (a three tier client/server application), services provided (real time DGPS data transportation from remote DGPS sources and campus wide data dissemination) and transmission modes implemented (raw and frame mode over TCP and UDP). Then we present and discuss the results obtained and, finally, we draw some conclusions.

Eficiência energética em edifícios residenciais da cidade do Porto

O consumo de energia a nível mundial tem atingido valores históricos, devido ao crescimento da população mundial e ao aumento do consumo per capita. Nesta medida é extremamente importante existirem alternativas para que a redução do consumo de energia de todos os países seja uma realidade, evitando também as consequências ambientais, em particular as alterações climáticas, resultantes da utilização intensiva de combustíveis fósseis. Portugal, tal como outros países da União Europeia, tem que cumprir metas, pelo que é urgente encontrarem-se soluções de forma a diminuir o consumo de energia sem interferir com o nosso dia-a-dia. A cidade do Porto, tal como qualquer cidade, precisa de imensa energia desde os transportes até à indústria, passando pelos edifícios. Os edifícios, residenciais e de serviços, são responsáveis por mais de 50% de energia primária consumida no concelho do Porto, sendo que aos edifícios residenciais corresponde um consumo de 1.473 GWh/ano de energia primária, o que é um valor elevado. Numa primeira parte deste trabalho foi efetuado um levantamento de informação caracterizando a cidade do Porto relativamente ao seu edificado e consumos energéticos. Numa segunda parte propuseram-se medidas para reduzir o consumo para cada tipo de utilização de energia, nomeadamente preparação de refeições, AQS (água quente sanitária), aquecimento ambiente, frio (frigorífico, arcas, etc.), outros e iluminação. Para cada um destes tipos de utilização estudou-se, sempre que possível, a evolução do longo do tempo (2004 a 2012) e possíveis cenários de evolução para o futuro. Para além disso, também se estudou a evolução do mix de produção de energia elétrica de 2004 até 2012 e previsões da evolução do mix para o futuro. Nesta análise foi tido em conta o aspeto ambiental contabilizando-se, sempre que possível, as emissões de poluentes resultantes do consumo de energia. Por fim, efetuou-se uma avaliação técnica, ambiental e económica das medidas propostas. Pode dizer-se que a maioria das medidas propostas a serem implementadas conduziria a uma redução do consumo de energia e consequentemente a uma diminuição das emissões de poluentes, em particular dos gases com efeito de estufa (CO2). Em termos técnicos a maioria das medidas pode ser aplicada embora algumas delas envolvam custos de investimento significativos. Dada a conjuntura atual, seria importante obter o financiamento necessário para a implementação das medidas propostas e a divulgação de medidas já existentes, tais como os programas para AQS e janelas eficientes.
