| Abstract | Proactive emergency rescue and reattempt strategies
are crucial for safety management in complex systems during
mission execution. This study considers systems that conduct
missions with random durations governed by general distributions.
Condition monitoring is used to gather real-time system
state information and track mission progress. Based on the collected
data on system condition and mission progress, decisionmakers
can choose to: (a) do nothing and proceed with the current
mission, (b) abort the mission and immediately initiate emergency
rescue with no further attempt, or (c) launch an emergency
rescue followed by a reattempt to complete the mission.
The primary goal is to minimize the total expected costs through
sequential, real-time decision-making on rescue and reattempts.
The problem is modeled as a Markov decision process, focusing
on optimizing rescue and reattempt policies. This work advances
mission abort research by introducing dynamic termination
thresholds that adapt to real-time system states, providing
a principled framework to balance mission reliability and operational
safety.
