STOCHASTIC TIMED ATTRIBUTED PETRI NET (STAPN) MODELING OF C(3) NETWORKS

THE OBJECTIVE OF THIS RESEARCH IS TO DETERMINE THE FEASIBILITY OF USING THE STOCHASTIC, TIMED, ATTRIBUTED PETRI NET (STAPN) METHODOLOGY TO DESCRIBE AND ANALYZE ALTERNATIVE NAVAL C3 ARCHITECTURES. THE US NAVY IS IN THE PROCESS OF DEVELOPING C3 ARCHITECTURES TO SUPPORT THE NAVY'S MISSION AND FUNDAMENTAL WARFARE TASKS. THIS PROCESS INVOLVES ASSESSING ALTERNATIVE C3 ARCHITECTURES TO DETERMINE THEIR IMPACT ON THE MISSIONS THEY SUPPORT. ANALYZING THE PERFORMANCE OF C3 SYSTEMS IS, HOWEVER, NOTORIOUSLY DIFFICULT DUE TO THE COMPLEX NATURE OF C3 AND THE PROBLEMS ASSOCIATED WITH RELATING VARIATIONS IN THE C3 SYSTEM TO THE PERFORMANCE OF THE MISSION IT SUPPORTS. STAPNS HAVE SHOWN PROMISE IN ADDRESSING THESE ISSUES. ALPHATECH PROPOSES TO CONDUCT THE FEASIBILITY STUDY BY WAY OF EXAMPLES, USING AN ANTISUBMARINE WARFARE (ASW) SCENARIO AS A CASE STUDY. WE WILL CONDUCT THE FIVE TASKS. 1) IDENTIFY AND DESCRIBE THE ASW SYSTEM AND SCENARIO TO BE MODELED. 2) CONSTRUCT A STAPN MODEL OF THE ASW SCENARIO. 3) IMPLEMENT AND EXERCISE THE STAPN MODEL FOR A BASELINE C3 ARCHITECTURE AND ONE ALTERNATIVE C3 ARCHITECTURE USING MODELER, ALPHATECH'S GRAPHICAL C3 SIMULATION TOOL; WE WILL COLLECT AND PERFORM STATISTICAL ANALYSIS ON MEASURES ASSOCAITED WITH THE ASW TOP LEVEL WARFARE REQUIREMENTS. 4) ASSESS THE FEASIBILITY OF STAPNS AND MODELER FOR NAVAL C3 ARCHITECTURAL STUDIES. AND, 5) PREPARE A FINAL REPORT DETAILING THE RESULTS OF THE PHASE I RESEARCH.
