Abstract

This paper outlines the results of a project concerned with investigating engineering techniques for real-time expert systems, and includes work concerned with parallel processing, formal specification, quality assurance and safety-critical systems. The authors seek to evalutate the utility of object-oriented programming languages for implementing an experimental real-time blackboard expert system for data fusion in naval command and control systems. The evaluation has taken the form of implementing the data-fusion model in two object-oriented programming languages, Smalltalk-80 and Lingo, and two conventional languages, Ada and C. The implementations are compared with regard to quantitative run-time performance and qualitative software engineering properties
