Chapter 2 : Modeling frameworks , paradigms , and approaches
نویسنده
چکیده
This chapter provides a general conceptual background to the more specific discussions of GIS-based environmental modeling presented in this book. It addresses three main themes central to environmental modeling: spatial models, complex systems, and geocomputation. The discussion covers static and dynamic, discrete and continuous, and social and natural system models, and helps put in perspective the diverse modeling approaches and issues presented in the following chapters. This chapter highlights the ‘systems’ perspective with an emphasis on spatio-temporal environmental systems representations. General classes of models rather than any specific ones are discussed, in particular, systems dynamics models under the ‘top-down’ paradigm, and cellular automata and agent-based models under the ‘bottom-up’ paradigm.

Chapter I Integrating the Fragmented Pieces of IS Research Paradigms and Frameworks : A Systems Approach
A formal conceptualization of the original concept of system and related concepts—from the original systems approach movement—can facilitate the understanding of information systems (IS). This article develops a critique integrative of the main IS research paradigms and frameworks reported in the IS literature using a systems approach. The effort seeks to reduce or dissolve some current researc...
متن کاملA UML-based Frameworks for Engineering of Interoperable Information Systems
We propose a four-layer architecture in the context of UML metamodeling. This allows modelers to use a three-step modeling process: 1) giving an informal description of the universe of the discourse (in terms of modeling paradigms); 2) defining a corresponding UML dialect (in terms of metamodels); 3) describing a model of an information system by using the chosen dialect. By using properties of...
