title The Role of Expert Systems, and RDBMS Strategies in a DSSfor Urban Bus Transport Management
source Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary Efficient and well-managed urban bus transport systems supported by information systems with decision support capabilities developed within the framework of an advanced Relational Data Base Management System (RDBMS) can provide critical information at the right moment and assisttransport managers in conducting performance evaluations. This paper includes discussions on the use of the entity-relationship (E-R) model (a semantic data modeling technique) in the development of thestructure of the conceptual database for the information system planned to be implemented using RDBMS. The E-R data modeling approach enables database designers in obtaining the third normal forms of related databases for the efficient functioning of the information system. The inportance of decision tables in the development of DSS modules using Expert System shells are also discussed. The DSS modules will assist transport managers in the analysis of operational performance for bus depots or the organization as a whole. The E-R diagrams generated and the decision files developed will serve as important documents that can enhance the adaptability of the DSS to the changing needs ofthe organizations. The conceptualization of the information system to support decision-making in an RDBMS framework provides the advantage of a very low 'disk seek' time and facilitates frequent generation of reports.
