摘　　要：建模与仿真应用于产品全生命周期管理中,提高了产品开发、使用及维护的效率和质量。但随着产品复杂程度的提高,其建模与仿真的框架越来越复杂,对环境变化的适应性要求也越来越高。以武器装备采办为背景,将仿真系统置于与真实系统平等、并行的地位,建立仿真情景模型,并采用多Agent技术探讨基于递阶结构的适应性仿真框架和技术。其中仿真情景的在线生成和逐层映射反映了系统的进展和环境的变化,并以此为动力驱动仿真的重组,体现了仿真系统的并行性、动态性、集成性等特点,可促进建模与仿真技术在产品全生命周期管理中的实施和应用。Modeling and Simulation（MS）,which are applied to product lifecycle management（PLM）,have the ability to impove the efficiency and quality of product development,usage and maintenance.But with products＇ complexity,the MS need high adaptability of environment change.Based on the background of weapon acquisition,an adaptive simulation framework,which adopts hierarchical multi-agent technology,was presented.Under the framework,scenario mo-dels,which drive reorganization of the simulation systems,were generated and mapped level by level according to the evolution of the real systems and their environment.The framework reflects the parallelism,dynamics and integrativity of the simulation systems,and can enhance the adaptability and application ability of MS throughout PLM.
