Abstract: Modeling and Simulation(M&S) , which arc applied to product lifccyclc managcmcnt(PLM)，have the ability to impove the efficiency and quality of product development, usage and maintenance. But with products' complexity, the M&S 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 models,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 Mc}S throughout PLM.
