Abstract

Mediative Fuzzy Logic was conceived as a practical scheme for reconciling hesitant or conflicting assessments in fuzzy control and decision-making. However, its logical and semantic foundations remain underdeveloped, especially beyond operational type-1 settings. This article develops a unified account of the type-1 core together with interval type-2, granular type-3, and quantum extensions. We characterize the mediative operator as a convex aggregation controlled by hesitation and contradiction, model mediative truth values as independent truth-falsity pairs in a continuous bilattice-like structure, and introduce a propositional system extending a standard t-norm-based fuzzy logic with a mediative connective. We establish soundness, paraconsistency, and conservativity over the underlying fuzzy base for formulas without mediation, and formulate coherent semantic extensions to interval type-2 truth values, granule-indexed local evaluations, and effects and density operators on Hilbert spaces. An autonomous-braking sensor-fusion example illustrates how the framework supports transparent, conservative, and safety-first decisions under incomplete, heterogeneous, and mildly contradictory evidence. Under suitable assumptions, the higher-level formulations reduce to the type-1 case, clarifying coherence across levels and reliably supporting future work in intelligent decision systems.

📋 한 줄 요약

**[Mediative Fuzzy Logic / 다층 통합]** Type-1 core·interval Type-2·granular Type-3·양자 확장의 통합 이론 — bilattice-like 진리값·mediative connective·t-norm 기반 propositional system으로 soundness·paraconsistency·conservativity 확립.

🎯 핵심 기여도

💡 핵심 아이디어

Mediative logic은 단순한 운영 기법이 아니라 type-1부터 양자까지 동일 핵심 구조(convex aggregation + bilattice 진리값)로 통합 가능하며, 더 상위 레벨이 적절한 가정 하에 type-1으로 환원됨으로써 계층 간 일관성과 안전 우선 의사결정을 동시에 보장한다.

📊 주요 결과

💭 의의 및 한계

**의의**: Mediative fuzzy logic의 의미·논리 기반을 본격 다층화, 양자까지 확장한 첫 통합 프레임워크, 안전 임계 시스템(자율주행 등)에서 신뢰성 있는 추론의 이론 근거 제공. **한계**: 응용 예시가 autonomous braking 단일 예제, 양자 확장의 실제 구현·실험 검증 부족, granular type-3의 실용 도구 미성숙.
