    Area of Science:

    • Biostatistics
    • Reliability Engineering
    • Mathematical Biology

    Background:

    • Survival analysis is crucial for understanding system viability.
    • Previous models by Gross, Clark, and Liu (1971) and Kodlin (1967) established foundational survival probability distributions.
    • Extending these models to more complex systems is essential for comprehensive analysis.

    Purpose of the Study:

    • To derive generalized survival probability distributions for two-organ systems where at least one organ is vital.
    • To extend the Markov process approach to analyze survival in k-organ systems.
    • To provide novel extensions of existing survival analysis results.

    Main Methods:

    • Utilized the Markov process approach for modeling system dynamics.
    • Derived survival probability distributions for two-organ systems.

  • Extended the derived distributions to a general k-organ system framework.

    • Main Results:

    • Developed generalized survival probability distributions for essential two-organ systems.
    • Successfully extended the Markov process methodology to k-organ systems.
    • Demonstrated extensions of survival analysis results beyond previous foundational studies.

    Conclusions:

    • The Markov process approach offers a robust framework for analyzing survival probabilities in complex organ systems.
    • The derived distributions provide a more general solution for systems with vital components.
    • This research lays the groundwork for analyzing survival in systems with up to k vital organs.
