首先构建了以控制模型为主，功能模型、资源模型、组织模型和数据模型为辅的三维集成化模型框架，通过控制模型建立起其他几个视图模型之间的内部关联，通过资源模型和组织模型来反映网络化制造系统中组织的分散性和过程对动态资源的调度与分配。

The scheme has the structure of hierarchical PKGs, so a lowerlevel PKG can share the workload of secret information generation and identity authentication with a higherlevel PKG. At the same time the scheme has the property of proactive security, that is, the whole lifetime of signature is divided into several time periods, and the shares of private key need to be renewed in each time period. However, new shares can construct the same private key as old shares.

方案具有分层的PKG结构，低层PKG可以分担高层PKG的秘密信息产生和身份认证的任务；同时具有动态安全的特性，将签名的整个生命周期分成若干时间段，每个时间段都对密钥份额进行更新，更新后的份额重构的密钥保持不变。

Research work has been done as follows:(1) Based on the full research of inherent characters of OBB hierarchical box, this thesis implements a series of key techniques such as building OBB and OBB tree, and overlap test between OBB boxes, verifies the attribute that OBB has the advantage that it is fit for the collision detection between rigid bodies and optimizes the shortcomings and disadvantages of OBB.

主要从事了以下几个方面的工作：(1)在研究OBB等层次包围盒固有特性的基础上，通过具体实现构建OBB和OBB树、包围盒间重叠测试等技术，比较了OBB适用于复杂环境中刚体碰撞检测的优势，并针对OBB存在的缺点和不足加以优化。

Based on the limitations of OBB, this thesis proposes an optimizing overlap test algorithm of bounding box and primitive. This method eliminates the bounding boxes of leaf nodes and streamlines the OBB hierarchical layer. This method also introduces a separating axis theory in the overlapping test between the primitives in order to accelerate the velocity.

针对基于OBB碰撞检测算法存在的缺陷，研究利用包围盒与基本几何元素相交测试的优化方法，消除叶子结点包围盒，精简OBB层次结构；同时在基本几何元素相交测试中引入类似分离轴的方法，加快检测速度。
