Applying qualitative modelling to environmental problems
نویسنده
چکیده
The analysis of many biochemical engineering problems in environmental modelling is based upon the development and solution of sets of differential equations. A complete analytical solution of such a model requires that every numerical constant in this set of equations is precisely known. This chapter describes some techniques, developed in the field of artificial intelligence, which permit the solution of such sets of equations when some constant values are either unknown, or only known imprecisely. The use of these techniques is illustrated with the use of models of anaerobic fermentors.

Background and Objective: Due to the increasing trend of municipal solid waste (MSW) production, if a suitable management system is not applied, it will lead to environmental pollution and endanger human health. The aim of this study was to compare different scenarios of waste management in Chalous city with life cycle assessment (LCA) approach and to select the most efficient method in terms o...
متن کاملA Framework for Applying Qualitative Spatial and Temporal Reasoning
Many application domains make extensive use of spatial and temporal information. However, the numerical approaches employed by most software tools have limitations, particularly when information is vague or incomplete. To address this, alternative qualitative spatial and temporal reasoning (QSTR) methods have been developed, yet few applications have made significant use of these techniques. In...

متن کاملImproving Environmental Decision-making: Bridging the Gap between Conceptual Modelling and Quantitative Analyses with Quasta
With regard to environmental decision-making, the field of conceptual modelling is primarily focused on representation and visualisation. As such, the ‘soft’ problem structuring methods have limited analytical value. On the other hand, quantitative analyses with various types of ‘hard’ models lack in flexibility and versatility. The Quasta approach as presented in this paper aims to bridge the ...
