Abstract

In this paper, we first introduce a systematic verification procedure for hierarchically structured avionics system. By making use of equipment models, it can perform individual verifications of each subsystem, integrated verifications of multiple subsystems, and an integrated verification of a whole system. A multi-mode system integration laboratory is then proposed to make it possible to execute various individual or integrated verification tests at the same time. By mathematically proving that the proposed multi-mode system integration laboratory needs less verification time than the conventional verification methodology, it is expected to enhance the efficiency of the systematic verification procedure and as a result, reduce the overall verification period and costs.

본 논문에서는 계층구조로 설계된 항공전자시스템의 체계적 검증을 위해 장비 모델을 활용하여 각 서브시스템 별 개별 검증, 다수 서브시스템들 간 통합 검증, 전체 시스템의 통합 검증 등으로 이루어진 단계적 검증 절차를 소개하였으며, 이를 기반으로 여러 단계의 시험이 1대의 통합시험환경으로 동시에 수행 가능한 다중모드 통합시험환경 개발 방안을 제안하여 기존의 순차적 시험 방식에 비해 시험 시간을 줄일 수 있음을 수학적으로 증명함으로써, 시험 효율성을 향상에 따른 검증 기간 단축과 비용 절감 효과를 입증하였다.
