摘　　要：实操精确度是评价GMDSS模拟器实操过程非常重要的指标,为更好地对其实施自动评价,将实际操作轨迹曲线和最优操作轨迹曲线进行对比,设计评价模型。由有向图和最短路径算法得出最优及实际操作轨迹曲线,利用改进的曲线相似性测量方法对比两种曲线,给出相似度评分数学模型,基于在线辨识和广度优先搜索辨识模型参数,使模型实现自适应。仿真结果表明,该模型能充分考量波动、步数和响应3个测度,自动评分过程直观形象,结果科学合理,算法速度满足要求,工程上可实现。方法具有普适性,可应用于不同的模拟训练系统。Operation accuracy is a very important index for evaluating operation process of GMDSS simulator.To evaluate operation accuracy well,evaluation model was designed based on comparisons of actual operating trajectory and optimal operating tra-jectory.Optimal trajectory and actual trajectory were obtained using the digraph and the shortest path algorithm.Comparisons of two trajectories were made using improved method of curve similarity measurement,and similarity score mathematical model was given.Model parameter was calculated based on on-line identification and breadth-first search so that the model achieved self-adaption.Results of simulation experiment show that the model can fully examine the fluctuation,step and response.The automatic scoring process is intuitive and the scoring results are reasonable.Fast algorithm verify that the method is practicable in engineering.The universal method can be applied to different simulation training systems.
