Midpoint-Based Decision-Making Criterion Between Fuzzy Sets: An Application to Medical Diagnosis Domain
The need to reach an agreement between two fixed positions arises in many practical problems. A typical example of this type of situation is given when two independent and reputed physicians provide two different patient descriptions. Here, healthcare professionals need to identify the most relevant description to support the diagnostic outcome.
Executive Impact: Revolutionizing Diagnostic Consensus
In medical diagnosis, particularly for complex conditions like suicide risk, divergent expert opinions and inherent uncertainty make consensus difficult, leading to varied diagnoses and treatment plans.

The research leverages fuzzy sets to represent uncertain medical data, such as symptom profiles or diagnostic probabilities. A patient's symptoms are modeled as a vector of membership values within the Kosko hypercube [0,1]^n. The core concept of midpoints between fuzzy sets, particularly using the Hamming distance, allows for the creation of a consensus position from divergent expert opinions.
Three main criteria are introduced to select a definitive midpoint from the potentially infinite set of possible midpoints: the Minimizer Criterion (optimistic, seeks highest utility), the Maximizer Criterion (pessimistic, seeks least utility), and the Weighted Average Criterion (a compromise combining both extremes with a realism coefficient α). These criteria reduce the decision space to a finite, manageable set of alternatives.
The framework is applied to a critical medical diagnosis scenario: assessing the potential risk of suicide. Two physicians' differing assessments of suicide risk (next month and three months out) are represented as fuzzy sets. The system then derives consensus midpoints, offering a data-driven approach to support the medical team in making a final diagnosis and treatment plan, validated by their experience.

Medical Diagnosis: Suicide Risk Assessment
Case Description: Two independent physicians provide patient descriptions (symptoms profile as fuzzy subsets) for a patient with potential suicide risk. The system calculates a consensus description using fuzzy set midpoints and a scoring function. The decision-making criteria (Minimizer, Maximizer, Weighted Average) are applied to obtain a finite set of distinguished midpoints, from which the medical team selects the final diagnosis.
Key Findings:
- Fuzzy set representation handles uncertainty in physician opinions.
- Midpoint calculation provides a consensual view.
- Scoring function allows for quantitative evaluation of outcomes.
