An Intelligent Distributed System for Environmental Management

Environmental management is a complex task. The amount and heterogeneity of the data needed for an environmental decision making tool is overwhelming without adequate database systems and innovative methodologies. As far as data management, data interaction and data processing is concerned we here propose the use of a Geographical Information System (GIS) whilst for the decision making we suggest a Multi-Agent System (MAS) architecture. With the adoption of a GIS we hope to provide a complementary coexistence between heterogeneous data sets, a correct data structure, a good storage capacity and a friendly user’s interface. By choosing a distributed architecture such as a Multi-Agent System, where each agent is a semi-autonomous Expert System with the necessary skills to cooperate with the others in order to solve a given task, we hope to ensure a dynamic problem decomposition and to achieve a better performance compared with standard monolithical architectures. Finally, and in view of the partial, imprecise, and ever changing character of information available for decision making, Belief Revision capabilities are added to the system. Our aim is to present and discuss an intelligent environmental management system capable of suggesting the more appropriate land-use actions based on the existing spatial and non-spatial constraints.

Accommodation management system using mobile devices

Os dispositivos móveis são pessoais, intransmissíveis e cada vez mais utilizados, tornando-se assim numa boa ferramenta para a realização de um conjunto de serviços na indústria hoteleira. Entre esses serviços que necessitam da identificação pessoal, encontram-se a possibilidade do cliente reservar um quarto ou utilizar o serviço de quartos. Atualmente é muito utilizado, nos locais de alojamento, um smart card que possibilite ao cliente ter acesso a alguns dos serviços disponíveis. O objetivo deste documento é apresentar uma alternativa ao sistema de cartões, utilizando para o efeito, dispositivos móveis. De modo a garantir a segurança e uma utilização semelhante ao sistema de cartões existentes foi utilizada a tecnologia NFC (Near Field Communication) que, ao permitir o modo de emulação de cartão, facilita a transação do sistema de smart card existente, para o da utilização de dispositivos móveis na realização das mesmas funções. Mais concretamente, será abordada a utilização de smartphones para o processo de abertura de portas. Para que exista uma melhor compreensão e para que haja um conhecimento das suas capacidades e limites foram estudados casos de uso da tecnologia NFC. Este documento apresenta ainda os processos de desenvolvimento de uma aplicação nativa para o sistema operativo Android, cujo objetivo é proporcionar ao cliente de um local de alojamento um novo modo de acesso ao quarto, utilizando a tecnologia NFC. Para além desta funcionalidade a aplicação permite ainda ao utilizador fazer reservas, fazer o check-in, fazer o check-out entre outras. Posteriormente serão apresentadas as conclusões e possíveis trabalhos futuros.

Battery management system for electric racing cars

With the introduction of the electrics cars into the market new technologies regarding the battery are being developed and new problems to be solved, one of them the battery management system because each type of cell requires a specific way of handling. This research is done using the active research method to find out the actual problem on this subject and features a BMS should have, understand how they work and how to develop them applied to the purpose on this work. Once the features the BMS should have are clarified, it’s possible to develop a BMS for an electric racing car. The decisions are made taking into consideration the nature of the vehicle being developed. After the project done it’s clear to see that what was developed was not only the BMS itself but all the other factors around it, such as CAN communication, safety control, diagnostics and so on.

Influence of Firms’ Environmental Management and Community Involvement Programs in their Employees and in the Community

To assure enduring success, firms need to generate economic value with respect for the environment and social value. They also need to be aware of the needs and expectations of relevant stakeholders and incorporate them in their business strategies and programs. These challenges imply that engineers should take into consideration societal, health and safety,environmental and commercial issues in their professional activity. This investigation accesses the influence of firms’ environmental management programs and community involvement programs on their own employees and in the community, with a focus on small and medium companies. Based on a quantitative research, the findings suggest that firms that invest both in environmental management programs and in community involvement programs have a higher involvement of their own employees with the community, while at the same time receiving more feedback (positive, but also negative) from the community, stressing the need to pay special attention to their communication policies.

Implementação do Sistema de Gestão Ambiental na Unidade Industrial de Gouveia, da Sumol+Compal

Esta dissertação descreve o levantamento da gestão de uma unidade fabril no âmbito do engarrafamento de águas, para a implementação de um Sistema de Gestão Ambiental (SGA) recorrendo á Norma NP EN ISO 14001:2012 tendo como objetivo proporcionar a melhoria contínua dos processos implementados na empresa bem como todos os benefícios que este referencial pressupõe. Foi realizada, numa primeira fase, uma auditoria diagnóstico com uma visita á fabrica no âmbito da implementação da ISO 14001, e posteriormente realizado todo o trabalho de aplicação ao referencial. Este trabalho consistiu a abordagem a todos os requisitos da norma ISO 14001 com principal foco na fase de Planeamento de um SGA, procurando-se responder essencialmente ao requisito 4.3 da referida norma. Procedeu-se á identificação das atividades da empresa (entradas e saídas), dos aspetos ambientais associados (respetiva significância) e levantamento dos requisitos legais aplicáveis (obrigações). Os restantes requisitos foram abordados e fez-se uma sugestão para o seu cumprimento, para além de que muitos já se encontram em cumprimento por compatibilidade com a norma ISO 9001 da qual a empresa já se encontra certificada. Esta dissertação pretende discutir e apresentar propostas para a implementação do SGA, possíveis vantagens daí decorrentes e as barreiras a ultrapassar (aspetos ambientais significativos) de maneiras a por em prática os requisitos do referencial normativo que venha a ser adotado. Foi realizada uma revisão bibliográfica destas temáticas e, ainda que estas medidas propostas não tenham sido implementadas, assim que implementadas esperam-se ganhos na economia de recursos como também outros benefícios descritos ao longo da dissertação que permita, com implementação do SGA não só enquanto estratégia, ser inovadora e competitiva.

Intelligent Distributed Environmental Decision Support System

This article discusses the development of an Intelligent Distributed Environmental Decision Support System, built upon the association of a Multi-agent Belief Revision System with a Geographical Information System (GIS). The inherent multidisciplinary features of the involved expertises in the field of environmental management, the need to define clear policies that allow the synthesis of divergent perspectives, its systematic application, and the reduction of the costs and time that result from this integration, are the main reasons that motivate the proposal of this project. This paper is organised in two parts: in the first part we present and discuss the developed Distributed Belief Revision Test-bed — DiBeRT; in the second part we analyse its application to the environmental decision support domain, with special emphasis on the interface with a GIS.

Environmental Decision Support: a Multi-Agent Approach

The environmental management domain is vast and encompasses many identifiable activities: impact assessment, planning, project evaluation, etc. In particular, this paper focusses on the modelling of the project evaluation activity. The environmental decision support system under development aims to provide assistance to project developers in the selection of adequate locations, guaranteeing the compliance with the applicable regulations and the existing development plans as well as satisfying the specified project requirements. The inherent multidisciplinarity features of this activity lead to the adoption of the Multi-Agent paradigm, and, in particular, to the modelling of the involved agencies as a community of cooperative autonomous agents, where each agency contributes with its share of problem solving to the final system’s recommendation. To achieve this behaviour the many conclusions of the individual agencies have to be justifiably accommodated: not only they may differ, but can be interdependent, complementary, irreconcilable, or simply, independent. We propose different solutions (involving both local and global consistency) to support the adequate merge of the distinct perspectives that inevitably arise during this type of decision making.
