Pattern Directed Approach Towards an Object Adaptive Decision Support Environmentfor Water Resources Management (Object Georienteerde Behandelings in Beslissingsondersteunende Systemen voor Waterbeheer)

摘要

This dissertation presents an approach to expanding applicability of a so calleddecision support environment in water resources management. Chapter 1 addresses one of the most fundamental problems, a lack of software effectiveness in decision support, the software-effectiveness. Chapter 2 argues that we may ease the concerns for the use of DSE in the new contexts, (1) decision making environment is an instance of virtual existence, and (2) the communications in DSE are aiming to facilitate the interactions between decision making environments. In Chapter 3, we have a very general frame of 'cooperative and distributed expert systems' (CDES) including a centralized control system (i.e., a blackboard system and front-end processors). Chapter 4 begins with the statements of the adopted principles in object-oriented paradigm, and the differences between our methods characterized as domain-driven object-modeling and the methods which have been already well established in software engineering. Then, it introduces an object-model based on GIS for decision support. Chapter 5 reveals the contexts where these kinds of data entities are normally used; It formulates a function for solving the problems of data entity-identifiers. Chapter 6 establishes a repertory grid method for knowledge acquisition. Chapter 7 introduces a method for constructing the effective conceptual schemas in chapter 8. Chapter 8 constructs effective conceptual schemas to support nonroutine vs. routine processes. Chapter 9 discusses the applicable interfaces implemented with AML in ARC/INFO systems.
