Abstract: Currently potency and level values arc used to present the metamodel hierarchy, but the problem that the same concepts could be defined in the different levels is not taken into account. In order to solve the problem, potency and domain field values were proposed to present the metamodel elements in the domain of Battlefield Environment(BE)simulation. The potency values are the instance times of level factors and the domain field values present whether the factors can be instanced between different level.

Key words: Battleficld environment, Metamodcl hierarchy, Potency value, Domain field value
