摘　　要：作为采办决策的支持手段,虚拟采办是以建模与仿真为工具对采办进度、费用、性能等作的综合论证,其要点包括复杂信息映射的一致性、多维动态仿真的并行和演进。本文以导弹武器装备采办为背景,研究虚拟采办中多维建模与仿真方法:以工作域、任务/子任务、资源等组成的多尺度工作分解结构作为多维仿真的基础,并将进度、性能、费用和资源等多维信息映射至统一的工作结构中;建立任务关系模型和属性关联模型,并将性能作为仿真循环和迭代的约束条件,采用任务调度/时间推进/多维并行机制进行仿真,实现采办仿真过程的并行和演进;同时,在进度、费用、性能等多维约束下分析采办满足预期综合要求的风险,为采办决策提供支持。Using modeling and simulation as tools, Simulation Based Acquisition（SBA） is a compre hensive demonstration of acquisition＇s scheduling, cost, performance, etc. The key points include the consistency of complicated information mapping, parallelization and evolution of dynamic multi-dimensional simulation. Against the background of missile acquisition, the methods of multi-dimensional modeling and simulation in SBA are studied. A multi-scale work breakdown structure（WBS）, which consists of domain decomposition, task/subtask decomposition and resource decomposition, is designed as a basis, and the information from different dimensions is mapped to WBS consistently. After the construction of task-relation models and attribute-association models, and using performance as the condition of loop iteration, the simulation process is carried out dynamically and in parallel, with a task-scheduling/ time-advancing/ dimension-paralelizing mechanism. And the methods for the evaluation of acquisition risk to meet the complicated requirements with comprehensive constraints from the dimensions of scheduling, cost, performance, etc. , are proposed to support acquisition decision-making.
