HLA仿真系统因果追溯性设计

随着仿真系统变得日益复杂，基于仿真数据人为的进行因果追溯已经变得越来越凼难，所以必须对原有的仿真系统进行因果追溯性设计，使自动或半自动追溯凶果成为可能。为此，首先确定了因果关系追溯的整体思路，然后面对普遍使用的高层体系结构HLA分印仿直系统，深入分析对象类和交互类两类交互数据以及交互特点，井详细划分行为事件及因果关系类型；对HLA仿真系统中关键的联邦对象模型FOM以及仿真器进行扩展设计，从而实现系统的因果追溯性，为仿真因果追溯分析提供必要的数据。最后提出保证因果追溯需要注意的几项设计原则，并对设计所能够支持的应用做出展望。

Causal Traceability Design for HLA Simulation System

While simulation system becomes more and more complex,causal tracing performed manually step by step becomes more and more difficult.So simulation system must be redesigned for traceability character to make automatic or semiautomatic causal tracing possible.The whole thought about causal tracing is put forward firstly.Then facing to HLA(High-level architecture) based distributed simulation system,a kind of simulation system used widely,its properties of data interaction and both types of data: object class and interaction class are studied deeply for traceability design.Behaviour events and causal relations are classified.From all above,FOM(federation object model) and simulator are redesigned.Thus simulation system can give necessary data for causal tracing.At last,some guide lines for design are discussed.And applications of causal tracing supported by designed simulation system are put forward.
