Decision-Making Model for Reliable Electronic Component Manufacturing in a Blockchain Environment

This study focuses on improving the efficiency of 5G ceramic antenna manufacturing through the application of blockchain and smart contract technologies. Using the Analytic Hierarchy Process (AHP), the relative importance of three key factors was assessed: 'Security', defined as the protection against unauthorized access and data integrity; 'Standards & Regulations', which refers to compliance with industry norms and legislative requirements; and 'Efficiency', highlighting process optimization and resource management. The findings indicate that 'Efficiency' is the most critical factor, with a weight of 0.545, followed by 'Security' (0.318) and 'Standards & Regulations' (0.137). Furthermore, the sub-factor analysis identifies 'Unit Gain', related to productivity improvements, and 'Integrity', concerning data veracity, as significant, with global weights of 0.309 and 0.111, respectively. These insights emphasize the critical role of chip efficiency in the manufacturing process. The study proposes an AHP-based decision model for effectively integrating blockchain technology in the 5G sector, offering strategies for optimizing antenna manufacturing. This approach not only delineates critical process elements but also promotes the advancement of blockchain applications in 5G technology, potentially catalysing substantial technological innovation.
