Belkin AT T Bell Laboratories Middletown NJ 07748 Robert F. Stengel Department of Mechanical and Aerospace Engineering Princeton University Princeton NJ 08544 Abstract An expert system Pilot-Aid is envisioned to automate many functional and low-level decision-making tasks in future high-performance and jet transport aircraft to help alleviate pilot workload. This chapter presents a design methodology for the development of multiple cooperating rule-based systems for the aircraft domain. Nine modular rule-based systems collectively called AUTOCREW were designed to automate functions and decisions associated with a combat aircraft s subsystems. The nine AUTOCREW knowledge bases were designed individually areas of cooperation between the knowledge bases were identified and common information was designated as shared information. Software tools were developed to aid in high-level design of the cooperating ensemble. An interactive graphical simulation testbed was developed to demonstrate and test the cooperating AUTOCREW ensemble s performance. Workload metrics were formulated to quantify AUTOCREW s performance in terms of the ensemble s efforts in assisting the Pilot. The workload metrics give reasonable results for the comparison of workloads among AUTOCREW s experts as well as comparative results among task groups within a single knowledge base. The applicability of the methods utilized to design AUTOCREW for other applications is also discussed. 372 INTELLIGENT AND AUTONOMOUS CONTROL INTRODUCTION This chapter describes a general approach to designing and prototyping cooperating rule-based systems. The approach was applied to the high-level design of an expert system Pilot-Aid to automate many functional and low-level decision-making tasks for aircraft operations. The details of the expert system can be found in 1 this chapter is intended to point out some of the critical issues associated with the .
