Managing the Brisbane River and Moreton Bay: an integrated research/management program to reduce impacts on an Australian estuary

The Brisbane River and Moreton Bay Study, an interdisciplinary study of Moreton Bay and its major tributaries, was initiated to address water quality issues which link sewage and diffuse loading with environmental degradation. Runoff and deposition of fine-grained sediments into Moreton Bay, followed by resuspension, have been linked with increased turbidity and significant loss of seagrass habitat. Sewage-derived nutrient enrichment, particularly nitrogen (N), has been linked to algal blooms by sewage plume maps. Blooms of a marine cyanobacterium, Lyngbya majuscula, in Moreton Bay have resulted in significant impacts on human health (e.g., contact dermatitis) and ecological health (e.g., seagrass loss), and the availability of dissolved iron from acid sulfate soil runoff has been hypothesised. The impacts of catchment activities resulting in runoff of sediments, nutrients and dissolved iron on the health of the Moreton Bay waterways are addressed. The Study, established by 6 local councils in association with two state departments in 1994, forms a regional component of a national and state program to achieve ecologically sustainable use of the waterways by protecting and enhancing their health, while maintaining economic and social development. The Study framework illustrates a unique integrated approach to water quality management whereby scientific research, community participation and the strategy development were done in parallel with each other. This collaborative effort resulted in a water quality management strategy which focuses on the integration of socioeconomic and ecological values of the waterways. This work has led to significant cost savings in infrastructure by providing a clear focus on initiatives towards achieving healthy waterways. The Study's Stage 2 initiatives form the basis for this paper.

Application of Gage R&R methodology for improving the training and evaluation of automatic optical inspection machine operators

The current level of demand by customers in the electronics industry requires the production of parts with an extremely high level of reliability and quality to ensure complete confidence on the end customer. Automatic Optical Inspection (AOI) machines have an important role in the monitoring and detection of errors during the manufacturing process for printed circuit boards. These machines present images of products with probable assembly mistakes to an operator and him decide whether the product has a real defect or if in turn this was an automated false detection. Operator training is an important aspect for obtaining a lower rate of evaluation failure by the operator and consequently a lower rate of actual defects that slip through to the following processes. The Gage R&R methodology for attributes is part of a Six Sigma strategy to examine the repeatability and reproducibility of an evaluation system, thus giving important feedback on the suitability of each operator in classifying defects. This methodology was already applied in several industry sectors and services at different processes, with excellent results in the evaluation of subjective parameters. An application for training operators of AOI machines was developed, in order to be able to check their fitness and improve future evaluation performance. This application will provide a better understanding of the specific training needs for each operator, and also to accompany the evolution of the training program for new components which in turn present additional new difficulties for the operator evaluation. The use of this application will contribute to reduce the number of defects misclassified by the operators that are passed on to the following steps in the productive process. This defect reduction will also contribute to the continuous improvement of the operator evaluation performance, which is seen as a quality management goal.

INTEGRATED MANAGEMENT SYSTEMS: CRITICAL SUCCESS FACTORS

The purpose of this paper is to, in a holistic way, identify and explore the critical success factors (CSFs) that are considered in the context of the growing discussions, movements, proposed models, and case studies about the integration of management systems (MSs). This work is an investigation focused on the integration of MSs into an integrated management system (IMS) and the proposed approach takes into account the literature review as well as the experience gained by the authors on researches about Portuguese enterprises. This qualitative and empirical research, investigated the integration of MSs from existing scientific publications for the period 1999 to 2014, on-going case studies and one inquiry conducted by the authors. This research contributes to a better understanding of the CSFs regarding the integration of MSs and thus provides an insight on the preventive management. This research shows an evident lack of information regarding case studies on CSFs for integrated management systems (IMSs) and has identified a set of relevant CSFs, for MSs integration and associated guidelines that organizations should take as a priority, in order to be able to manage, on a preventive way, the implementation of IMSs, and consequently to become more competitive with added value for the stakeholders.

Integration of Standardized Management Systems: A Dilemma?

Abstract: The growing proliferation of management systems standards (MSSs), and their individualized implementation, is a real problem faced by organizations. On the other hand, MSSs are aimed at improving efficiency and effectiveness of organizational responses in order to satisfy the requirements, needs and expectations of the stakeholders. Each organization has its own identity and this is an issue that cannot be neglected; hence, two possible approaches can be attended. First, continue with the implementation of individualized management systems (MSs); or, integrate the several MSSs versus related MSs into an integrated management system (IMS). Therefore, in this context, organizations are faced with a dilemma, as a result of the increasing proliferation and diversity of MSSs. This paper takes into account the knowledge gained through a case study conducted in the context of a Portuguese company and unveils some of the advantages and disadvantages of integration. A methodology is also proposed and presented to support organizations in developing and structuring the integration process of their individualized MSs, and consequently minimize problems that are generators of inefficiencies, value destruction and loss of competitiveness. The obtained results provide relevant information that can support Top Management decision in solving that dilemma and consequently promote a successful integration, including a better control of business risks associated to MSSs requirements and enhancing sustainable performance, considering the context in which organizations operate.

O IMPACTO FINANCEIRO DAS AUDITORIAS DA QUALIDADE NAS EMPRESAS PORTUGUESAS

This paper discusses the main theme the financial implications that Portuguese companies with the implementation and subsequent certification of the Quality System and respective Quality Audits. The literature review shows that companies do not publish financial results on the subject in question, making it necessary to acquire information through a questionnaire. About 126 questionnaires were sent. Our sample is however 32 validados.Pode to complete questionnaires that the top 5 overall benefits or indirect financial benefits for Portuguese companies were, respectively: improving internal organization; improving the company's image; increasing customer satisfaction; continuous improvement in customer service; improving competitive position. In terms of direct financial benefits the 3 main benefits obtained by the companies were: turnover increase; Performance (cost reduction); Increased business productivity. So it is expected to contribute to the knowledge of the impact, notably financial of Quality Management Systems and respective audits in Portuguese companies.

A bot spooler architecture to integrate virtual worlds with e-learning management systems for corporate training

Joining efforts of academic and corporate teams, we developed an integration architecture - MULTIS - that enables corporate e-learning managers to use a Learning Management System (LMS) for management of educational activities in virtual worlds. This architecture was then implemented for the Formare LMS. In this paper we present this architecture and concretizations of its implementation for the Second Life Grid/OpenSimulator virtual world platforms. Current systems are focused on activities managed by individual trainers, rather than groups of trainers and large numbers of trainees: they focus on providing the LMS with information about educational activities taking place in a virtual world and/or being able to access within the virtual world some of the information stored in the LMS, and disregard the streamlining of activity setup and data collection in multi-trainer contexts, among other administrative issues. This architecture aims to overcome the limitations of existing systems for organizational management of corporate e-learning activities.

Towards the wide implementation of standards IEC 61968/70 (CIM) and IEC 61850 in the distribution system (CIGRÉ C6-105_2010)

Currently, power systems (PS) already accommodate a substantial penetration of distributed generation (DG) and operate in competitive environments. In the future, as the result of the liberalisation and political regulations, PS will have to deal with large-scale integration of DG and other distributed energy resources (DER), such as storage and provide market agents to ensure a flexible and secure operation. This cannot be done with the traditional PS operational tools used today like the quite restricted information systems Supervisory Control and Data Acquisition (SCADA) [1]. The trend to use the local generation in the active operation of the power system requires new solutions for data management system. The relevant standards have been developed separately in the last few years so there is a need to unify them in order to receive a common and interoperable solution. For the distribution operation the CIM models described in the IEC 61968/70 are especially relevant. In Europe dispersed and renewable energy resources (D&RER) are mostly operated without remote control mechanisms and feed the maximal amount of available power into the grid. To improve the network operation performance the idea of virtual power plants (VPP) will become a reality. In the future power generation of D&RER will be scheduled with a high accuracy. In order to realize VPP decentralized energy management, communication facilities are needed that have standardized interfaces and protocols. IEC 61850 is suitable to serve as a general standard for all communication tasks in power systems [2]. The paper deals with international activities and experiences in the implementation of a new data management and communication concept in the distribution system. The difficulties in the coordination of the inconsistent developed in parallel communication and data management standards - are first addressed in the paper. The upcoming unification work taking into account the growing role of D&RER in the PS is shown. It is possible to overcome the lag in current practical experiences using new tools for creating and maintenance the CIM data and simulation of the IEC 61850 protocol – the prototype of which is presented in the paper –. The origin and the accuracy of the data requirements depend on the data use (e.g. operation or planning) so some remarks concerning the definition of the digital interface incorporated in the merging unit idea from the power utility point of view are presented in the paper too. To summarize some required future work has been identified.

A gestão dos custos da qualidade: Modelo A.B.Q.C. aplicado à Mercauto

Mestrado em Controlo e Gestão dos Negócios

Influência da implementação de um sistema de gestão nas concessões rodoviárias

Se a implementação de Sistemas de Gestão dentro dos padrões recomendados pelas normas individuais de referência, já é prática comum nas empresas nacionais, a implementação de Sistemas Integrados de Gestão (SIG), verdadeiramente contidos uns nos outros como um só, é ainda invulgar. Constitui actualmente emblema de modernidade, enquanto aplicado à construção. Estudar todos os meandros e práticas associadas aos SIG, neste pequeno‐grande mundo, que é o das obras concessionadas, é de facto um grande desafio, não tanto pela novidade do conceito que representa, mas pela possibilidade de idealizar uma proposta de uma sistemática exequível, que me proponho apresentar. Assim, este trabalho baseia‐se numa pesquisa de informação teórica, bem como na prática da implementação de um Sistema Integrado numa empresa de referência no sector – a Empresa de Construções Amândio Carvalho, S.A. e neste caso, concretamente na obra ‐ “VRI: Aeroporto/IP4 – Lote 3”. O objectivo geral baseia‐se em diagnosticar as principais dificuldades e limitações enfrentadas por um sector de actividade, na adopção de um modelo específico de gestão da qualidade, ambiente e segurança no trabalho, baseando‐se nas normas de referência, ISO 9001: 2000, ISO 14001:2004 e OHSAS 18001: 2001. Normas estas, que embora agora tenham sido revistas a primeira e a última, na altura em que a obra decorreu, encontravam‐se em vigor. No caso especifico de estudo, comprova‐se a necessidade de implementação de um Sistema único, que atinja o nível de comprometimento dos recursos financeiros e humanos necessários para a execução de obra, respeitando os princípios apresentados pelo cliente. Pretende‐se ainda demonstrar que a adopção de Sistemas “desintegrados”, poderá conduzir ao colapso da estrutura montada para corresponder aos requisitos propostos.

Referenciais de segurança alimentar: estudo comparativo

Perante a crescente preocupação dos consumidores, cada vez mais exigentes com os produtos e serviços que lhes são fornecidos, têm-se evidenciado esforços no sentido da aplicação prática e coordenada de uma abordagem global e integrada da segurança alimentar com o objectivo de melhorar as normas da qualidade e reforçar os sistemas de controlo em toda a cadeia alimentar, desde a exploração agrícola até ao consumidor final. Os referenciais normativos de segurança alimentar especificam os requisitos de um Sistema de Gestão da Segurança Alimentar, para organizações da cadeia de fornecimento de produtos alimentares, que pretendam demonstrar a sua aptidão para fornecer produtos seguros e o cumprimento de requisitos legais, regulamentares e de qualidade exigidos. Ao longo dos anos, diversos referenciais normativos, baseados na metodologia HACCP, foram desenvolvidos e publicados, por vários países e determinados sectores da cadeia alimentar. Perante a diversidade de referenciais existentes, cada vez mais, as organizações se questionam sobre qual o referencial de segurança alimentar a implementar. Nesta dissertação, dá-se uma contribuição no sentido da sistematização dos requisitos dos referenciais de segurança alimentar com o objectivo de suportar a respectiva comparação nomeadamente o IFS – Food, o BRC – Food, a FSSC 22000 e, de forma indirecta, a ISO 22000. Tal deve-se à necessidade de identificar o(s) referenciais de segurança alimentar a implementar numa dada organização pertencente a um dado sector de actividade. Finalmente, procede-se à realização de um estudo sobre a representatividade, número de empresas certificadas, dos referenciais em análise no mercado Nacional, Europeu e Internacional. Como conclusão genérica, é possível afirmar que, embora ao nível dos requisitos existam diferenças entre os referenciais em análise, também se verificam muitas semelhanças. Prova disso é o reconhecimento por parte da GFSI de vários destes referenciais Quanto à representatividade, verifica-se uma tendência de predomínio de determinados referenciais nos países onde foram desenvolvidos, e nos países com os quais mantêm relações comerciais mais fortes. Refere-se o Reino Unido para a BRC, e a Alemanha e França para a IFS. De salientar a importante contribuição da GFSI que, através do reconhecimento aos diversos referenciais de segurança alimentar, realizado por uma painel de especialistas e representantes de diversos sectores (industria, distribuição e serviços) está a contribuir para a respectiva harmonização e reconhecimento mundial.
