复杂工程的建模仿真方法

An Approach to Complex Engineering Modeling and Simulation

提出了一种针对复杂工程的建模和仿真方法。比较复杂工程和复杂系统的异同,以及复杂工程仿真和一般工程仿真的区别,由此总结出复杂工程仿真的特点和要求。提出根据面向人员以及所用方法论的差异,将复杂工程的建模分为两个阶段,在第一个阶段中采用层次化的任务建模方法,面向实际工程人员,第二个阶段中采用模块化的实体行为建模,面向仿真技术人员。通过对仿真建模任务的区分,由各自擅长的人员完成,并通过层次化和模块化方法的采用,降低复杂工程仿真建模的复杂度,形成一种适合于复杂工程的仿真方法。

<Abstrcat> An approach to complex engineering modeling and simulation is presented. The characteristics and the requests of complex engineering simulation are concluded from comparing it to a general engineering simulation and a common (complex) system simulation. Modeling of complex engineering is divided into two steps according to the persons it oriented and the methodology it used. In the first step, which is oriented to the realistic engineering technicians, a hierarchy method is used to modeling the tasks of the complex engineering, in next step, which is oriented to the simulation technicians, a modularization method is used to modeling the action of the simulation entities. Thus the complexity of the simulation is (reduced) by allocating different tasks to their experts and the adoption of the hierarchy and the modularization methods. An example is given to prove its application.
