Decision trees and rule-based system including variants based on propositional and fuzzy logic have been the method of choice in many applications of environmental decision support systems. Reasons are the ease of use, the capability of representing uncertainty, and the fast computation of results at runtime when using decision trees or other similar means for knowledge representation. Unfortun...

Much research has been done on interfacing databases to visualization applications, and there are many varied approaches. We describe the lessons learned during the design and development of the REINAS software (Real-time Environmental Information Network and Analysis System). We have developed visualization applications that have been in public use for several years and that visualize data fro...

[Motivation:] Environmental sustainability is an important concern. Information and communication technology (ICT) innovation is ambivalently positioned with regard to our rapid development and shortening innovation cycles. On one hand, information technology facilitates the (excessive) usage of resources. On the other hand, ICT can also help to significantly reduce human impact on the environm...

Decision Support Systems for the environment have to incorporate and exploit knowledge about the phenomena and the interdependencies in the affected natural systems, i.e. a model. We discuss different tasks and requirements, provide a logical formalization of the tasks, and propose to use methods and techniques developed in research on modeling and model-based systems in Artificial Intelligence...

Artificial Intelligence (AI) researches have begun to use AI techniques and methodologies for developing Knowledge Management Systems (KMS) for different domains and technologies. Expert systems are considered one of the well know techniques for knowledge management and can be aid in solving problems in specific domain. Case-based reasoning has been successfully used for managing knowledge of i...

Companies that are seeking to improve their environmental performance have a challenge in reconciling high level goals and practical decision making at the working level. To address this challenge companies need to develop key environmental metrics from high level goals and cascade them through all levels of management decision making. One decision-making level of interest in manufacturing invo...

For the support of analysis and decision making in the environmental domain, we propose a knowledge-based system with explicit representation of expertise in the domain and the specific ecosystem in the form of qualitative dynamic models. The choice of qualitative modeling techniques is motivated by the very nature of the processes examined, the available information and style of reasoning empl...

Sustainability has become a key concern for consumers and industry. However, coming to understand its implications in the context of daily life can be difficult. It may be hard to come to terms with the idea that traditional activities present environmental risks and may lead to real emergencies, manifested differently depending on local conditions. Everyone will be asked to do more but the mov...

—EMDS is a knowledge-based decision support system for the design and conduct of ecological assessments at any geographic scale. ArcView provides the primary system interface to the EMDS system. The NetWeaver development system incorporated into EMDS provides a knowledge base development environment in which an assessment team assembles a knowledge base that describes the logical relations (dep...
