Reliability risk analysis and control strategy of COTS devices in aviation equipment

Abstract

With the rapid advancement of aviation equipment, the adoption of commercial off-the-shelf (COTS) devices in aviation equipment has witnessed a substantial rise. As these devices are not specifically designed for aviation equipment with high safety and reliability requirements, their widespread use may give rise to numerous challenges and issues. Therefore, conducting reliability risk analysis and control of COTS devices is crucial for ensuring the performance and reliability of aviation equipment. This paper examines the fundamental conditions and current issues regarding the test and evaluation work of COTS products in U.S. military aviation equipment. Furthermore, it conducts a thorough analysis of the reliability risks associated with COTS devices in aviation equipment. Subsequently, a strategy and procedure for managing reliability risks related to COTS devices in aviation equipment is proposed. The results of the application case analysis demonstrate the effectiveness of the proposed method in identifying and capturing the key factors associated with the reliability risk of COTS devices. This subsequently guides the assessment and control of reliability risks associated with COTS devices in aviation equipment.
