tra<strong>in</strong><strong>in</strong>g and development p rocess. In the last part of the course, all modules are put together for f<strong>in</strong>al system prot otype<br />

and test.<br />

In this paper we describe one of the projects developed by a group of studen ts tak<strong>in</strong>g the MMKBS course <strong>in</strong> Spr<strong>in</strong>g of<br />

1996.<br />

3.1 FixCarAC Project De velopment:<br />

The focus of this project was to develop a net-based multimedia expert syste m to diagnose and repair automobile air<br />

condition<strong>in</strong>g systems [7]. The ma<strong>in</strong> goal w as to practice and implement pr<strong>in</strong>ciples and topics presented <strong>in</strong> lectures. The<br />

secondary goal was to develop a useful system which can be made available to the public. The system's architecture was<br />

to allow <strong>in</strong>cremental upgrade of knowledge base and the multimedia repository with m<strong>in</strong>imal impact on its utilization<br />

and GUI <strong>in</strong>terface.<br />

This system was <strong>in</strong>itially developed as a pilot project on one car only to test its ease of use, and adaptability to other<br />

cars. The <strong>in</strong>itial phase of the system development focused on knowledge acquisition by <strong>in</strong>terview<strong>in</strong>g A/C mechanics on<br />

the work<strong>in</strong>gs of a typical automobile A/C system. In addition, detailed <strong>in</strong>ter views were also conducted to obta<strong>in</strong><br />

specific <strong>in</strong><strong>format</strong>ion about the A/C system of the Honda Civic.<br />

At the present stage, the system can be run <strong>in</strong> its entirety from the <strong>in</strong>terne t browser, or from the Nexpert Object shell<br />

with access to an <strong>in</strong>ternet browser. The two systems share many of the data file s. If a user does not have access to a net<br />

browser, the Nexpert-based system could be adapte d to run on its own stand-alone multimedia modules. The only<br />

change would be that the data files wo uld need to be reconfigured to a different file <strong>format</strong>, and the po<strong>in</strong>ters <strong>in</strong> the<br />

Nexpert code will need to be m odified to po<strong>in</strong>t to the new data files.<br />
