基于一个理论框架，从理论上提出了一种新的分类器联合方法，并对该联合方法进行了性能估计。 - One of the main problems in pdes is how to partition the network simulation workload to decrease the time needed to complete the simulation and improve performance of simulation . here a new optimized partition algorithm was put forward , which first analyses the performance factors of parallel simulation and then constructs a performance estimation model for partition ; based on this model , it mends the graph partition algorithm to consider all factors , including simulation applications and simulation environments . optimized factors are workload balance 、 communication cost and time window of lookhead
鉴于基于传统图划分算法的任务划分工具存在诸多不足,本文提出了并行网络模拟任务的优化划分方法,其思想是:首先从pdes机制出发,分析影响并行网络模拟性能的各种因素并建立一个能够综合考虑各种因素的并行网络模拟性能估计模型;其次,改进多级图划分算法,使得算法具有综合考虑模拟应用与模拟运行环境,同时在优化过程中使用性能估计模型指导划分,实现对影响并行网络模拟性能的三个因素(包括负载均衡、通信开销、安全时间窗口长度)的优化能力;最后,结合并行网络模拟性能估计模型与改进的多极图划分算法,实现了并行网络模拟任务的优化划分。 - The same conclusion as derived from the original pda under approximate condition is concluded this way without any approximations . the second method is the instant - state performance prediction based on the hyca method . this method not only gives the off - line recursive error variance relation , but also gets a series of performance measurement such as track life
然后应用两种方法对其进行性能估计和预测，一是基于riccati方程的稳态性能估计，其结果与pda算法近似条件下得出的结论相同；二是基于hyca方法的瞬态性能预测，不仅给出了误差方差的离线递推关系，而且得到了航迹寿命等一系列性能指标的估计值。 - On the ground of mpda algorithm and the conclusion of its steady - state performance evaluation , the choice of the detection threshold becomes a matter of optimization under the condition of properly chosen detection model and hypothesis . and the analytic expression of auto - adjusted detection threshold can be deduced via approximate fitting attenuation factor derived from the conclusion of performance estimation . it presents a novel approach for the optimization of detection - tracking system
基于mpda算法及其稳态性能估计的结论，在适当选择检测模型和一定假设条件下，将自适应检测门限的选择归结为一个最优化问题，通过近似拟合性能估计结论中的衰减因子，得到了最佳检测门限自适应调整的解析表达式，为检测?跟踪系统的联合优化设计提供了一种新思路。
