Electrification structures design for railway systems is a crucial and complex process, since it compounds plenty of infrastructure elements, design decisions, and calculation conditions. In this paper, an ontologydriven decision support system for designing complex railway portal frames is presented and developed. A knowledge-rules database has been also developed relying on experts knowledge ...

In the last few years, much research has been dedicated to the development of decisions support systems for the space system engineers or even of completely automated design methods capturing the reasoning of the system experts. However, the problem of taking into account the uncertainties of the variables and models to determine an optimal and robust spacecraft design has not been tackled effe...

Complex soflware environments, such as CAD systems, consist of many modules which are often created, maintained, and executed separately. When slick systems are invoked, appropriate execution sequences and parameters must be determined for each modiile so that desired results are produced. The task of planning, executing, and supervising the CAD environments has become so complex that it itself...

Decisions in today's competitive and turbulent environments without access to information can confuse managers. The information system, which is planning, design and deployment as efficient and effective way, can help to improve the organization and create competitive advantage. One of the success factors and effectiveness of information systems in organizations is the organizational factors...

Sustainable integrated catchment management is a complex task that often involves finding compromise between the views of multiple stakeholders that may not easily be brought to consensus. Interactive three dimensional (3D) visualisations of landscapes can facilitate discussion, but these can only partially inform decision makers as many important aspects of interventions are abstract. Such abs...

introduction: studies have indicated a global high prevalence of hospital malnutrition on admission and during hospitalization. clinical nutritional risk screen (cnrs) is a way to identify malnutrition and manage nutritional interventions. several traditional and non-computer based tools have been suggested for screening nutritional risk levels. the present study was an attempt to employ a comp...
