Metamodel construction method and system suitable for weapon system

The invention provides a meta-model construction method and system suitable for a weapon system. The meta-model construction method comprises the following steps: realizing missile weapon system modeling by utilizing a description weapon system composition class meta-model, a description weapon system logic architecture class meta-model and a description weapon system activity description class meta-model; the description weapon system composition class meta-model describes various elements contained in the weapon system by using a meta-model language suitable for the weapon field; according to the description weapon system logic architecture class meta-model, a meta-model language suitable for the weapon field is used for describing the logic relation and function division between a weapon system and a weapon subsystem; the class meta-model for describing the weapon system activity process is used for designing and deducing a combat activity process which is carried out by using a meta-model language suitabl
