摘　　要：针对基于Unity引擎的车间仿真系统加载过程中内存占用大,导致系统在运行时存在卡顿、不流畅的现象,从模型资源加载角度设计一种资源动态调度算法.首先通过四叉树算法将场景递归的分割成多个叶子节点进行存储,然后结合资源动态调度算法以摄像机位置为中心对周边节点的资源进行预设实例化和预设销毁完成内存的管理.最后根据Unity的内存管理机制,设计并实现了对场景资源的动态调度和内存优化,实验结果表明资源动态管理算法有效控制某时刻内存中加载的数据量相对稳定降低了IO总量,避免了漫游移动时造成的内存颠簸,使系统的运行更加流畅.Unity engine-based manufacturing simulation system occupies large memory when loading, resulting that the system is not fluent at run time and cannot run smoothly. In response to this phenomenon, we design a resource dynamic scheduling algorithm from the perspective of model resource loading. Firstly, the scene is recursively divided into a plurality of leaf nodes for storing through a quad-tree algorithm. Then, combined with the resource dynamic scheduling algorithm, taking the camera position as the center, the resources of surrounding nodes are defaulted instance and destruction of the prefab to complete the memory management. Finally, according to Unity＇s memory management mechanism, the dynamic scheduling and memory optimization of scene resources are designed and implemented.
