基于相位差渐进循环协调的应急车辆优先信号控制

为了提高应急车辆的通行效率,针对应急车辆需要“绝对优先”路权的特点进行了信号控制的研究,提出了一种基于相位差渐进循环协调的信号控制策略,并将其与应急车辆优先信号配时转换策略相结合进行应急车辆优先信号控制,给出了应急车辆优先信号配时转换控制策略和动态相位差的计算方法。在由三交叉口组成的城市道路系统中,采用三种应急车辆的信号控制策略进行了微观仿真实验,结果表明,文章提出的基于相位差渐进循环协调的应急车辆优先信号控制策略通过对各交叉口相位动态循环渐进微调后,再采用应急车辆优先信号配时转换策略进行控制,可以使应急车辆安全不停车地通过交叉口,且达到了对非应急车辆影响最小的效果。     

信息化助力研究型企业管理效率提升

做为现代企业的重要模式研究型企业因其独特的盈利模式更需要提升管理效率．管理体系信息化是提升管理效率的重要手段,但是管理信息系统开发的目的以及应用过程会影响到它在企业内部的应用效果,系统开发完毕后在企业被空置、流于形式的现象大量存在．如何使管理信息系统真正成为企业管理的有效辅助工具需要从系统建设目的和建设过程开始研究．本单位立足企业自身管理体系,以满足管理人员日常管理需要为目标,采用敏捷开发方法将管理体系信息化,取得了良好效果．     

Decentralized MDPs with sparse interactions

Creating coordinated multiagent policies in environments with uncertainty is a challenging problem, which can be greatly simplified if the coordination needs are known to be limited to specific parts of the state space. In this work, we explore how such local interactions can simplify coordination in multiagent systems. We focus on problems in which the interaction between the agents is sparse and contribute a new decision-theoretic model for decentralized sparse-interaction multiagent systems, Dec-SIMDPs, that explicitly distinguishes the situations in which the agents in the team must coordinate from those in which they can act independently. We relate our new model to other existing models such as MMDPs and Dec-MDPs. We then propose a solution method that takes advantage of the particular structure of Dec-SIMDPs and provide theoretical error bounds on the quality of the obtained solution. Finally, we show a reinforcement learning algorithm in which independent agents learn both individual policies and when and how to coordinate. We illustrate the application of the algorithms throughout the paper in several multiagent navigation scenarios.

Surface Reconstruction based on Lower Dimensional Localized Delaunay Triangulation

We present a fast, memory efficient algorithm that generates a manifold triangular mesh S passing through a set of unorganized points P R ³. Nothing is assumed about the geometry, topology or presence of boundaries in the data set except that P is sampled from a real manifold surface. The speed of our algorithm is derived from a projection-based approach we use to determine the incident faces on a point. We define our sampling criteria to sample the surface and guarantee a topologically correct mesh after surface reconstruction for such a sampled surface. We also present a new algorithm to find the normal at a vertex, when the surface is sampled according our given criteria. We also present results of our surface reconstruction using our algorithm on unorganized point clouds of various models.
