Abstract
Electromagnetic compatibility (EMC) is a critical aspect of electronic and electrical systems, ensuring their ability to function properly within a shared electromagnetic environment without causing or suffering from unacceptable interference. This study employs the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS), a multi-criteria decision-making method, to evaluate and rank various EMC parameters. The analysis considers several key EMC factors, including the EMC directive, radiated emissions, conducted emissions, electromagnetic interference (EMI), EMC standards, and electromagnetic susceptibility (EMS). The EMC directive, which serves as a guiding framework for managing electromagnetic disturbances in devices, emerged as the top-ranked criterion, underscoring its pivotal role in regulatory adherence and standardization. Radiated emissions and conducted emissions secured the second and third ranks, respectively, highlighting their substantial impact on EMC performance. Effective management of these emissions is crucial for mitigating potential interference with communication systems, aircraft equipment, and other electronic devices, thereby enhancing the reliability and coexistence of products within the electromagnetic spectrum. Electromagnetic interference (EMI) and EMC standards followed closely, ranking fourth and fifth. EMI shielding and compliance with EMC standards are vital for preventing disruptions caused by electromagnetic radiation and ensuring the smooth operation of electronic circuits and wireless networks. Adherence to these standards promotes interoperability and minimizes the risk of performance degradation. Lastly, electromagnetic susceptibility (EMS) ranked sixth, emphasizing the importance of assessing the sensitivity of electronic devices to electromagnetic energy. By understanding and mitigating EMS, manufacturers can enhance the immunity of their products to external interference, reducing the likelihood of operational issues or physical damage. The TOPSIS method facilitated a comprehensive analysis by considering the ideal and negative ideal solutions, ultimately ranking alternatives based on their proximity to the optimal scenario. The results underscore the multifaceted nature of EMC and the need for a holistic approach that considers various aspects, from regulatory directives to emission control and interference mitigation. By leveraging the TOPSIS method, decision-makers can prioritize and allocate resources effectively, ensuring that EMC challenges are addressed comprehensively and proactively, thereby promoting the harmonious coexistence of electronic systems within the electromagnetic environment.
