This interface is a part of DATAPLEX, a heterogeneous distributed database management system that will provide location-transparent access to diverse databases using SQL in the engineering and manufacturing environment. The initial target DBMSs to be interfaced are IMS, DB2, and INGRES. For IMS, the hardest to provide with an SQL interface, an SQL interface called SQL/IMS was developed. A method which translates IMS data definitions is developed. A procedure which decomposes an SQL query into a set of simple IMS-processable queries and recomposes partial results is derived. SQL/IMS was tested using a small test database and a large production database. The performance of SQL/IMS is compared with that of another system used to access IMS data.<<ETX>>","PeriodicalId":228213,"journal":{"name":"Proceedings.

This forms the basis of a prototype to enable an evaluation and analysis of the reasoning methodology to be conducted, using artificial-intelligence tools. The prototype is designed to give assistance at different levels in the design and manufacturing processes including the introduction of novel methods of reasoning about potential products and manufacturing approaches.<<ETX>>","PeriodicalId":228213,"journal":{"name":"Proceedings.

The resulting CAD system consists of a design representation database, an existing-design database, and a parts catalog database. The design representation database stores and manages designs currently being developed. The existing-design database and the parts catalog database serve as suggestion systems. The first suggestion system helps the designer by recommending an existing design that closely satisfies the input specifications. In the second suggestion system, the user provides an incomplete component specification and the system suggests a set of standard components that fit these descriptions. A structure-function CAD modeling paradigm is used to represent designs, to perform simulations, and to let designs evolve over time. The structural information represents the physical or the logical aspects of the design, whereas the functional information represents the behavioral aspects of the design.<<ETX>>","PeriodicalId":228213,"journal":{"name":"Proceedings.

In the architecture, the relational database is used to find designs in the object database, and the object database is used to support the concurrent editing of designs by multiple users and processes on networks of workstations. The architecture has the advantage of allowing the relational database to concentrate on providing fast indexing methods to find designs, and allowing the object database to concentrate on providing good concurrency and version control tools for design editing. The authors describe the two-part architecture, give classifications for the types of data that can be extracted from the object database and put into the relational database, and give formulas that can be used to quantify the size of the relational database.<<ETX>>","PeriodicalId":228213,"journal":{"name":"Proceedings.

(An ATP system is a railway signaling system consisting of a set of logic circuits that control the safe movements of trains within a railway station.) Artificial intelligence techniques proved feasible to address this particular design problem, and ADES, which uses artificial intelligence techniques, makes it possible to design good control circuits to meet operational requirements rapidly by using well-structured, explicitly represented knowledge on ATP. ADES' inference engine works as a partial evaluator for the knowledge representation language KARL which is used to write design rules. Since every circuit produced by the expert system is still expressed in KARL, the KARL interpreter has also been used as a simulator for a designed circuit. Prototypes of the inference engine and the KARL interpreter have been implemented as extended Prolog metainterpreters.<<ETX>>","PeriodicalId":228213,"journal":{"name":"Proceedings.

Moreover, they cannot recognize such situations, which often lead to an incorrect diagnosis or at best an exhaustive search through their knowledge bases. The CONSOLIDATE system is a hybrid diagnostic system which integrates experiential and causal-model-based knowledge sources, which retains the efficiency of experiential-based approaches while providing a mechanism to recognize and address previously unobserved situations. A discussion is given the CONSOLIDATE system, issues related to novel fault hypothesis generation, and the approach utilized to address these issues.<<ETX>>","PeriodicalId":228213,"journal":{"name":"Proceedings.
