The design and maintenance of an aero-engine generates a significant amount of documentation. When designing new engines, engineers must obtain knowledge gained from maintenance of existing engines to identify possible areas of concern. We developed a Semantic Web based document repository for transferring front-line maintenance knowledge to design. The Semantic Web is an ideal candidate for this application because of the size and distributed nature of an aerospace manufacturer's operation. The Semantic Web allows us to dynamically cross reference documents with the use of an ontology. However, during the design and implementation of this project, we found deficiencies in the W3C 1 recommended Semantic Web query language SPARQL. It is difficult to answer questions our users sought from the document repository using SPARQL. The problem is that SPARQL is designed for handling textual queries. In industrial applications, many common textual and semantic questions also contain a numerical element, be it data summarization or arithmetic operations. In this paper, we generalize the problems we found with SPARQL, and extend it to cover web applications in non-aerospace domains. Based on this analysis, we recommend that SQL-styled grouping, aggregation and variable operations be added to SPARQL, as they are necessary for industrial applications of the Semantic Web. At the moment, to answer the non-textual questions we identified with an RDF store, custom written software is needed to process the results returned by SPARQL. We incorporated the suggested numerical functionalities from SQL for an example query, and achieved a 21.7% improvement to the speed of execution. More importantly, we eliminate the need of extra processing in software, and thus make it easier and quicker to develop Semantic Web applications.

A large hypermedia application has been developed to demonstrate the concept of factory wide hypermedia to support the maintenance of a major process line. As part of its development cycle, the performance of the software and its acceptance by the user community has been fully evaluated. The evaluation method considered in this paper focuses on the subjective opinion of the users and measured the ease with which users could retrieve the information required to perform specific tasks, and is considered suitable for other large industrial hypermedia applications. This research draws together standard evaluation techniques into a methodology for evaluating an industrial strength hypermedia application. The trials undertaken showed that the users were able to find the identical information in approximately one-third of the time when using the hypermedia system, over a paper-based system, which equate to a significant cost savings during unscheduled maintenance periods. #

“…While there is clearly a need for hypermedia information delivery, only a few exemplar hypermedia applications have been reported in the literature, including those for maintenance applications Fakun 1998, Hsu et al 1999), medical record keeping (Ip et al 1995) and historical archives (Dunlop et al 1996). When reviewing previous applications, it is noticeable that the majority of published industrial hypermedia applications use manually generated pointto-point embedded link technology, which while easy to implement is very di cult to manage and maintain.…”

As industrial systems become increasingly more complex, the maintenance and operating information increases both in volume and complexity. With the current pressures on manufacturing , the management of information resources has become a critical issue. In particular, ensuring that personnel can access current information quickly and e ectively when undertaking a speci®c task. This paper discusses some of the issues involved in, and the bene®ts of using, open hypermedia to manage and deliver a diverse range of information. While the paper concentrates on the problems speci®cally associated with manufacturin g organizations , the problems are generic across other business sectors, such as healthcare, defence and ®nance. The open hypermedia approach to information management and delivery allows a multimedia resource base to be used for a range of applications and it permits a user to have controlled access to the required information in an easily accessible and structured manner. Recent advancement in hypermedia also permits just-in-time support in the most appropriate format for all users. Our approach is illustrated by the discussion of a case study in which an open hypermedia system delivers maintenance and process information to factory-¯oor users to support the maintenance and operation of a very large manufacturin g cell.
