Next-Gen Medical Intelligence: Fuzzy Logic-Driven Expert Systems For Clinical Decision-Making

Abstract

The complexity and uncertainty inherent in clinical environments demand robust, adaptive, and intelligent decision support systems. Traditional rule-based expert systems often fail to accommodate the ambiguity and imprecision characteristic of real-world medical data. This paper explores the integration of fuzzy logic into expert systems to enable next-generation clinical decision-making support. Fuzzy logic offers a powerful mathematical framework for modeling uncertainty, incorporating linguistic variables, and approximating human reasoning. The paper reviews the design, architecture, and real-world applications of fuzzy expert systems across various domains such as diagnostics, prognosis, and treatment planning. Recent advancements in hybrid models—integrating fuzzy logic with machine learning, deep learning, and IoT—are highlighted, showcasing the potential for scalable, context-aware, and personalized healthcare delivery. The study also discusses implementation challenges, including knowledge acquisition, rule optimization, and computational complexity. Results from recent clinical case studies demonstrate improved decision accuracy and clinician trust in fuzzy logic-based systems. This research underscores the critical role of fuzzy logic in empowering intelligent clinical decisions, contributing to the ongoing evolution of precision medicine and patient-centric care.
