의사결정론을 통한 EMP 방호대책 및 수준 판단방안 제시에 관한 연구

A Study on the Method for Judging the EMP Protection Plan and Required Level through Decision Making

Abstract

한반도 안보상황에서 주변국들에 의한 EMP 위협이 고조되는 상황에서 EMP 방호시설은 군의 작전수행능력을 보장할 수 있는 매우 중요한 수단이다. 이러한 EMP 방호시설은 작전을 수행하는 부대의 다양한 요소들을 종합적 고려하여 구축하여야 한다. 하지만 현 군 관의 EMP 방호기준은 80dB의 일률적인 차폐효율만을 요구하고 있다. 본 연구에서는 전문가 집단의 의견을 통해 객관적이고 통계적 방법을 사용하여 방호요구수준의 고려사항을 재선정하고자 한다. 연구방법은 델파이기법을 사용하였으며, 53명의 EMP방호 설계기준과 관련 있는 전문가들을 선정하였다. 1차 설문은 EMP 방호의 적정수준에 대하여 조사하였고, 2차 설문은 방호대책 수립시 고려요소에 대하여 분석하였다. 채택된 전문가의 의견에 대해 요인분석을 실시한 결과, EMP 방호요구수준 설정시 METT+TC 요소를 고려하여야 한다는 것을 확인하였다.

In the context of increasing threats of EMP by neighboring countries in the security situation on the Korean peninsula, EMP protection facilities are a very important means of ensuring military operational capability. These EMP protection facilities should be constructed by comprehensively judging various factors about operation units. However, Defense Military Facilities Criteria and National Technical Guideline for EMP protection require at least 80dB shielding effectiveness without considering other options. In this study, we use objective and statistical methods to refine the consideration of the required EMP protection level based on the opinions of the experts. To do this, the Delphi technique is used for this study, and the survey was conducted from 53 experts related to EMP protection standard in the military and civilian sectors. The first questionnaire investigated the appropriate level of EMP protection, and the second questionnaire analyzed the factors considered in establishing EMP protection level. As a result of the factor analysis on the opinions of the experts, it was concluded that the EMP protection requirement level should be determined by variables of METT + TC.
