A high performance spatial modeling and simulation environment based on grid

摘要

Multidisciplinary and multi-scale researches demand integrating different models usually created by different approaches into an application. This gives a new challenge for spatial modeling and simulation, and promotes researches on integrated modeling and simulation. Multi-paradigm modeling and modeling framework are two main categories of these researches. The former implements integrated modeling in methodology level, and the latter in component level. This paper presents a spatial modeling and simulation toolkit named SMSE that combines system dynamics and geoprocess to provide an integrated modeling environment. The environment embeds ESMF, a widely used modeling framework, and provides a graphical interface, which makes modeling much easily. To solve the time-consuming problem of spatial simulation, a parallel processing environment is built on person computers under the support of grid technique, which gives SMSE little hardware limits and better applicability.
