Reliability Calculation Method of Shipborne Vehicles' Sortie Mission for Dynamic Network Structure.

Area of Science:

• Naval Engineering
• Operations Research
• Reliability Engineering

Background:

• Effective decision-making for naval operations requires accurate assessment of shipborne vehicle sortie mission reliability.
• Current methods may not sufficiently address the complexities of vehicle layout and mission task characteristics.

Purpose of the Study:

• To develop a sortie mission network model and reliability calculation method for shipborne vehicles.
• To provide a quantitative basis for evaluating shipborne vehicle layouts and supporting commander decision-making.

Main Methods:

• Established a sortie mission network model based on vehicle layout and task characteristics.
• Transformed the problem into a two-terminal network reliability problem.
• Utilized the minimal path set method with an improved tabu search algorithm and sum of disjoint products for calculation.

Main Results:

• Developed a novel method for calculating shipborne vehicle sortie mission reliability.
• Demonstrated the method's effectiveness through numerical analysis of simplified layouts.
• Provided a new evaluation index for shipborne vehicle layout systems.

Conclusions:

• The proposed method offers an effective quantitative basis for shipborne vehicle layout evaluation.
• This research provides theoretical support for decision-making in sortie mission planning.
• The study enhances the operational readiness and effectiveness of naval forces.
