Abstract

The author presents a knowledge-base design for problem representation and modeling support which provides an integrated (unified) environment for the organization, manipulation, and management of data, problems, and models; that represents knowledge at the conceptual-schema level and at the data structure level; and supports multiple levels of abstraction for problem/model representation. He proposes an extended entity-relationship model for the conceptual-schema representation, and an object-oriented model for the data structure representation. The mapping from the E²R model to the object-oriented representation is quite natural. Problem representation, model building, and decision support under this approach are based on modeling by deduction which is implemented using three processes: instantiation, inheritance, and specialization
