However, due to the complexity of the models, the sharing of models' specification becomes an arduous process, which makes it difficult to validate and replicate this type of model. To assist in this process, experts from the domain have developed the ODD (Overview, Design concepts, Details) protocol to help systematize ABM descriptions. However, because it is a protocol, the latitude allowed in the description of the models and the format in which these descriptions are made only address part of the problem. On the one hand, it may remain difficult to understand the description, and on the other hand, the access and processing of the ODD descriptions are still a manual task. To solve the problem, a framework, based on an ontology, was developed to allow traceability of ABM described with ODD. Concepts from other metadata initiatives, such as Dublin Core and Codemeta, were included to add important data to the ODD protocol. An application was developed to facilitate the access to the models, which allows the analysis of the data source of the model and the extraction of the protocol components. An API was also developed that gives access to ABM descriptions and promotes the processing of ABM descriptions. The application is ready for a series of tests to validate our approach, the usability of the application and the utility of the framework.

In order to know and to control the greenhouse microclimate smart sensing nodes with wireless communication capabilities represents the solution. As one of promissory protocol associated with wireless sensor network can be mentioned the ZigBee due to its low cost, low power consumption, extended ranges and architecture flexibility. In the present work a sensing and control sensing nodes with ZigBee communication capabilities are considered, while the microclimate is monitored using a set of solid state sensors for temperature, relative humidity, light intensity and CO2 concentration considering this parameters with important role in...

Despite the increasing number of models built by experts and users, it is not always guaranteed that one is able to replicate the basic results of a research model nor to understand it. In this paper, we raise the questions that need to be answered in order to cope with ABM specification issues. We review some of the existing solutions that have been developed. We aim to address this problem by building a framework that includes a domain specific modelling language to respond to ABM documentation concerns. We show that ideas from the Web Semantic can enhance the understanding of ABM and improve users’ trust in this kind of tools.info:eu-repo/semantics/publishedVersio

For infrastructure asset management (IAM) planning those data need to be processed and transformed into information. However, information management efficiency often falls short of desired results. This happens particularly in municipalities where management is structured according to local government models. Along with the existing IS at the utilities' disposal, engineers and managers take their decisions based on information that is often incomplete, inaccurate or out-of-date. One of the main challenges faced by asset managers is integrating the several, often conflicting, sources of information available on the infrastructure, its condition and performance, and the various predictive analyses that can assist in prioritizing projects or interventions. This paper presents an overview of the IS used by Portuguese water utilities and discusses how data from different IS can be integrated...

Esta metodologia será operacionalizada por ferramentas informáticas, de onde se destaca o papel dos Sistemas Multi-Agentes (SMA). Serão produzidos cenários de desenvolvimento com o objectivo de contribuir para a avaliação de estratégias de gestão quanto aos seus impactes sobre a biodiversidade. A área de estudo escolhida foi o Parque Natural de Sintra-Cascais (PNSC). A necessidade da participação pública e de processos colaborativos em questões ambientais tem vindo a ser amplamente reconhecida. A localização do PNSC na Área Metropolitana de Lisboa com os crescentes problemas de escassez de espaço e pressão humana, reforçam a relevância de uma abordagem participativa ao seu planeamento e gestão.

In this research project, we survey existing solutions that have emerged to cope with models specification issues. We then propose another approach: a domain specific modeling language for agent-based simulations of land use/cover change. This language is intended to constitute a means to promote models' validation and reuse. We also present the general methodology for the development of the modeling language which consists in extending existing conceptual modeling languages with domain-specific language profiles. We also present the first step towards its development comprising a domain model based on a domain ontology.

A área caracteriza-se por condições climatéricas, geográficas, geológicas, e um potencial hídrico que a tornam ideal para o estudo de metodologias aplicadas à gestão de sistemas cársicos em regiões secas, mas com importante procura de água.

The objective of this work is to analyze its environmental consequences and propose some alternatives to the current approach, drawing alternative scenarios to minimize the environmental impacts of this industry. The characterization and modeling of actors and processes have been made and a simulation system will be implemented using multi-agents systems, Geographical Information Systems (GIS) and environmental models. The paper focuses on the definition of agents, on the interaction with environmental models and their geographical representation.

Water utility engineers and managers make decisions based on data that are obtained from several information systems (IS), such as geographic information systems (GIS), billing, asset operation and maintenance or accounting. Most of the time, these IS result in data silos as a consequence of lack of machine communication protocols, common data formats or common meaning of exchanged content. On the other hand, the diversity of IS is a challenge to water utilities which struggle with data consistency and interoperability. In this context, water utility engineers and managers make decisions based on data which are often incomplete, inaccurate or out-of-date. In this paper, we present an IT platform that integrates data from different information systems, including tools to support decision-making on water supply systems (e.g., performance indicators, water, and energy balances). This platform, developed in collaboration with a representative set of Portuguese water utilities, allows water utilities to integrate their data and perform analysis of their systems. With this approach, we provide water utilities and water supervision agencies with the possibility to compute a unified set of metrics whatever the IS they use.
