    Decision analysis with multiple tests can create complex decision trees. This study simplifies them using a maximum expected utility table, leading to efficient Boolean logic for minimum-cost testing sequences.

    Area of Science:

    • Decision analysis
    • Medical diagnostics
    • Information theory

    Background:

    • Decision trees in medical diagnostics can become complex with numerous investigations.
    • Managing these complex trees is challenging for optimal patient management.

    Purpose of the Study:

    • To simplify complex decision trees in decision analysis.
    • To develop a method for finding minimum-cost testing sequences.

    Main Methods:

    • Deriving a maximum expected utility decision table as an intermediate step.
    • Summarizing the decision table using Boolean expressions.
    • Manipulating Boolean formulas to find optimal testing sequences.

    Main Results:

    • A simplified approach to decision analysis for riskless tests.
