Linear Constant Discrete System Based Evaluation of Equipment System-of-Systems

Abstract

AbstractTo meet the demand that analyzing the impact of architecture and equipment performance on capability and cost of equipment system-of-systems, an evaluation method is investigated based on linear constant discrete system. Model of equipment system-of-systems is established using state space equation of linear time invariant discrete system, which describes equipment composition, connection relation, operation process and equipment performance of the equipment system-of-systems. Operation characteristic of the equipment system-of-systems is analyzed using state motion equation of linear time invariant discrete system. Then, evaluation models for adaptation capability, survivability capability, task capability and response capability are established, as well as a cost evaluation model for equipment system-of-systems are given. The method proposed in this paper is demonstrated with a hypothetical air defense equipment system-of-systems. Evaluation results of the above capabilities and cost of the air defense equipment system-of-systems are derived. These results can support optimization of the equipment system-of-systems architecture and equipment performance.KeywordsEquipment system-of-systemsCapability evaluationArchitectureEquipment performanceLinear constant discrete system
