## 6 Conclusions and Prospects  
Using reconfigurable ship electronic information system as the research subject, this study proposes a mission reliability design and analysis method by analyzing the structural composition and failure mode of the system, aiming to improve the mission reliability level of ship electronic information system and enhance the development efficiency and development quality of ship electronic information systems. First, a comprehensive mission reliability model of the system is established using AADL language, which lays the foundation for the subsequent reliability allocation and analysis. Then, the AADL mission reliability formula generation software is developed, and the reliability allocation model is solved using the SMA-DE hybrid optimization algorithm. Next, the transformation rules for mapping AADL structural, behavioral, and fault models into operators, signal flow of the GO method are established, and the dedicated mapping software is developed. Finally, the application validation of the allocation and quantitative calculation of reliability is achieved in combination with a typical ship electronic information system mission. Among them, in the application validation of reliability allocation, the objective function value of the SMA-DE calculation is 1.97, which is lower than the value of 2.04 calculated by the DE algorithm, and the iteration number of the SMA-DE algorithm is less. In the application validation of the quantitative calculation of reliability, the method proposed in this study can achieve accurate results. The results of three kinds of mission reliability for air-to-air, land-to-land, and sea-to-underwater missions are 0.8815, 0.8779, and 0.8264, respectively, which are consistent with the results of the modified quantitative calculation of mission reliability. In summary, the mission reliability modeling, allocation, and analysis method proposed in this study can successfully achieve the reliability allocation

under multi-mission requirements, and the quantitative analysis of the mission reliability of reconfigurable ship electronic information systems. It significantly reduces the cost of system development while providing a high degree of automation. However, there are still shortcomings in the current research. First, the research on reconfigurable ship electronic information systems lacks sufficient depth, and the second is that the designed software has not reached the degree of complete automation. Therefore, in future research, further consideration will be given to other states such as the advanced state of the unit and the maintainability of the system. Additionally, the focus will be on improving the automation degree of the software to further improve the research efficiency and accuracy of reliability analysis while reducing manual intervention.
