COMPLEXITY METRICS FOR AVIONICS SOFTWARE

THIS RESEARCH WILL INTEGRATE THE MOST GENERALLY ACCEPTED SOFTWARE COMPLEXITY METRICS AND EXTEND THEM TO AVOINICS SOFTWARE. THE EXTENSIONS WILL ADDRESS THE ADDITIONAL FEATURES OF MULTITASKING, INTERTASK COMMUNCATION, REAL-TIME CONTRAINTS, AND ERROR RECOVERY PROVISIONS THAT ARE PRESENT IN ADA SORUCE CODE. IT IS HYPOTHESIZED THAT THIS INTEGRATION AND THESE EXTENSTIONS WILL ENABLE US TO BETTER MEASURE THE COMPLEXITY OF AVIOINICS SOFTWARE. IN PHASE I A TOOL, CMAS, WILL BE DEVELOPED WHICH ANALYZES ADA SOURCE CODE FOR THE METERICS WHICH ARE GENERALLY ACCEPTED WITHING THE RESEARCH COMMUNITY. IN PHASE II, A FULL SCALE ANALYSIS OF AVIONICS SOFTWARE AND OTHER REALTIME ADA APPLICAITONS WILL BE UNDERTAKEN AND CARRIED TO THE DESIGN PHASE OF THE SOFTWARE LIFECYCLE. THE RESULT OF THE RESEARCH WILL BE A VERSATILE ANALYSIS TOOL COUPLED WITH A SOUND PREDICTION METHODOLOGY TAILORED TO AVIONICS SOFTWARE.
