최적화 모델링 언어를 위한 객체 지향 모형 관리 체계의 개발

Abstract

A new model management framework is proposed to accommodate wide-spreading algebraic modeling languages (AMLs), and to facilitate a full range of model manipulation functions. To incorporate different modeling conventions of the leading AMLs (AMPL, GAMS, and SML) homogeneously, generic model concepts are introduced as introduced as a conceptual basis and are embodied by the structural and operational constructs of an Object-Oriented Database Management System (ODBMS), enabling the framework to consolidate components of DSSs (database, modelbase, and associated solvers) in a single formalism effectively. Empowered by a database query language, the new model management framework can provide uniform model management commands to models represented in different AMLs, and effectively facilitate integration of the DSS components. A prototype system of the framework has been developed on a commercial ODBMS, ObjectStore, and a C++ programming language.
