其次进行了预案相似度的研究，说明了一些距离函数，文章采用了引入权重的相似性计算方法和基于HEOM(Hetetogeneous Euclidean-Overlap Metric)的方法，来计算灾害预案的相似性。

Using colour systems such as is computationally prohibitive, but in practice it is adequate to use a Euclidean distance metric in components coded nonlinearly according to video practice.

And a solution for crowd path navigation based Voronoi diagram is presented. By making use of the ability that the Voronoi diagram partitions the space according to the Euclidean metric, the path planning with collision avoidance is achieved by forbidding agents to move outside their Voronoi regions.

利用Voronoi图对平面按照欧式距离进行划分的特性，并通过将每个虚拟人的Voronoi区域作为其活动范围，使每个虚拟人都限制在自己的区域内活动，从而在人群路径规划中避免了为虚拟人进行碰撞检测的复杂操作。

The new IRS algorithm has greatly improved the approximation performance of the original reduced set method by embedding a new distance metric called image Euclidean distance into the kernel function.

其中，所谓IRS算法是指在精简集算法的核函数中嵌入一种新的距离度量——图像欧式距离——来改善其迭代近似性能，IRS可以有效地生成新的、位于类别边界附近的虚拟样本以增强给定训练集。
