DESIGN AND IMPLEMENTATION OF CORROSION INHIBITOR KNOWLEDGE BANKⅠ-System Architectures Function Design and Knowledge Distribution

A state-of-art design of corrosion inhibition knowledge bank is proposed with intentions of easier information sharing and knowledge distribution in order to minimize effort of new inhibitor development. While designing such as knowledge bank, several key design objectives, like simplified operation, expandability, flexibility and so on, have been kept in mind. Each of those objectives has been rationed in detail. First of all, a dedicated discussion of database schema as the core component of the knowledge bank is done in order to clarify its impact on overall system performance. The detail of arrangement of tables and composition of each table are addressed and illustrated. Three architectures of inhibitor knowledge bank are proposed to meet the various usage environments. Then, focuses are laid on the information retrieving, data mining and knowledge forming one by one since those are assumed to be "must-have" functions. The issues of system configuration and integration are addressed; and the approaches to these issues are discussed including pros and cons. The overall picture of inhibitor knowledge bank system is outlined at the end.
