Abstract: A new Element-Relation-Operation set mode suits open, complex and versatility of resource and environmental system; mathematical formula semantic is adopted in describing relation set, and semantic mapping is realized by the late binding of computational components. The comparison between mathematical formulas semantic representation mode and model class-
instance express mode shows the mathematical formulas representation enhances the user-friendliness of Resource and Environmental Model-base Management System(REMMS) and covers more relation set of models avoiding the repeat construction of model class module; decoupling system for relation set and operation set is implemented by semantic dynamic mapping, which makes operation set is independent from relation set and computational implementation can be shared and recombined with different models.

Key words: resource and environmental system, mathematical formulas, ERO set, Resource and Environmental Model-base Management System(REMMS)

摘要: 针对资源环境系统的开放性、复杂性和易变性特点,将模型表达划分为要素集、关系集和运算集(ERO集合);采用数学公式语义描述关系集,计算组件的迟绑定,实现模型的语义映射。通过与模型类模型实例的模型表达比较说明,模型的数学公式语义表达增强了资源环境模型库管理系统(REMMS)的用户友好性,涵盖了更多的模型关系集,避免了重复构建模型类模块;语义的动态映射实现了模型的关系集和运算集的解耦合,使得模型计算集不依赖关系集,计算实现可被不同模型共享和重组。
