The author reports on the results of a study performed by a team from RAND Corp. and the 7th Communications Group (USAF) for the Office of the Assistant Secretary of Defense for Production and Logistics, published as The Guide for the Management of expertsystems Development, R-3766-P&L, and Additional Appendixes, N-2970-P&L by Iris Kameny, Umar Khan, Jody Paul, and David Taylor. The study guides managers and technicians seeking expertsystems (ES) solutions. It is noted that, as ES developments are software engineering efforts, the lessons learned building software over the past decades still apply. DoD software engineering and life-cycle policies can be applied to ES developments. The practical methodology elaborated in the study maps the rapid prototyping paradigm to DoD standards using the spiral model and risk containment strategies as described by B. W. Boehm. Furthermore, software life-cycle management and documentation standards reflect a hardware bias which also affects conventional software developments. Other peculiarities of ES developments are not totally unique to expertsystems, either. Modern conventional software developments are experiencing many of the same problems. Hence, it is concluded that the standards and acquisition practices of yesterday need to evolve to accommodate the nature of software development in the 1990s and beyond.

The Log Quality Monitoring system (LQMS) is a medium-sized knowledge-based system that was developed to address the problem of providing real-time assistance to the wireline field engineer. The authors discuss the motivation for the project, review the major decisions that were made, detail how they affected the direction of the project, and identify the basic lessons that were learned. The research version of LQMS was developed at Schlumberger-Doll Research over a period of about three and a half years. The project successfully dealt with several thorny issues in the development of knowledge-based systems: multiple domain experts, real time constraints, embedded environment, coordination and communication of multiple knowledge sources, and technology transfer. The project evolved from an exploratory, rapid prototyping style of development to a more traditional specify/design/implement/test methodology. Much of this evolution was driven by the field testing and technology transfer requirements of the later stages of the project.

A troubleshooting expertsystem has been designed to provide repair and diagnostic information for aircraft inertial navigation systems (INS). The inertial navigation system intelligent diagnostic expert (INSIDE) is used to diagnose faults in an INS system, and to train new operators on the troubleshooting of an INS system, thus freeing up the experienced engineer for other projects. INSIDE leads a new engineer through the conventional fault paths and step-by-step through repairs, thus alleviating the primary training and greatly diminishing the part-time training. The IN intelligent diagnostic expert uses a fault path algorithm. The fault tree is traversed by a rules-based inference engine written in the Level5 expertsystem shell. It is comprised of one main, executive knowledge base and five more detailed knowledge bases. The system supports graphics, and interfaces with a BASIC program to perform simple, pertinent computations on the request of the operator.

Aspects of rapid expertsystem (ES) prototyping using ES shells for personal computers are presented. Three shells--1st-class, VP-expert, and Personal Consultant Plus (PC Plus)--are discussed. Aspects of ES prototyping based on the experience accumulated from several ES development projects with VP-expert and PC Plus are examined. These studies resulted in the development of operational ES software. The usefulness and cost-effectiveness of ES shells for personal computers for experimenting with ES technology and rapidly creating user-friendly ES prototypes are demonstrated. Examples of the capabilities created, namely, hierarchical structuring of the problem knowledge base, inclusion of graphics as static and dynamic images, incorporation of calculations, and integration with databases, are presented. Issues for future studies are discussed.

At times, for a variety of reasons, an expertsystem will provide incorrect information or advice, and, as result, a party will suffer injury, either physical or economic. The author reviews various theories under which a party so injured might sue to recover damages and assesses the problems the plaintiff and defendant might face under each theory. He also briefly discusses potential liability for failure to use an expertsystem.< >
