船舶电网系统状态对于船舶安全航行产生直接影响，为此研究基于进化差分算法的船舶电网系统状态评估方法，保障舰船安全航行。采用文献法与专家咨询法构建初始舰船电网系统状态评估指标体系，利用进化差分算法在初始评估指标体系内筛选指标，构建最终用于评估舰船电网系统状态的指标体系。采用模糊综合评估方法，确定评估结果划分等级，计算评估指标权重值，构建综合评估矩阵，通过评估矩阵与权重值实现舰船电网系统状态模糊综合评估，获取评估结果。测试结果显示，该方法所构建评估指标体系的整体Cronbach?s α系数值在0.85以上，显著高于标准值，且所得评估结果与舰船电网系统当前状态一致，说明了评估结果的准确性。
The state of ship power grid system has a direct impact on the ship's safe navigation. Therefore, the evaluation method of ship power grid system state based on evolutionary difference algorithm is studied to ensure the ship's safe navigation. The initial evaluation index system of ship power grid system state is constructed by literature method and expert consultation method, and the index system used to evaluate the ship power grid system state is constructed by using the evolutionary difference algorithm to screen the index in the initial evaluation index system. The fuzzy comprehensive evaluation method is adopted to determine the grade of the evaluation results, calculate the weight value of the evaluation index, construct the comprehensive evaluation matrix, and achieve the fuzzy comprehensive evaluation of the ship power grid system status through the evaluation matrix and the weight value to obtain the evaluation results. The test results show that the overall Cronbach evaluation index system constructed by this method′s α coefficient value is above 0.85, which is significantly higher than the standard value, and the evaluation results are consistent with the current state of the ship power grid system, indicating the accuracy of the evaluation results.
