Requirement meta model construction method and device

The embodiment of the invention provides a requirement meta model construction method and device. The method comprises the following steps: obtaining requirement data from a requirement database, wherein the requirement data are used for representing a design requirement of a vehicle; obtaining structure tree data of the vehicle from a structure tree database, wherein the structure tree data of the vehicle comprise component parts of the vehicle and a hierarchy relation of the component parts; constructing a requirement meta model of the vehicle layer by layer by using the requirement data according to the structure tree data; storing the requirement meta model into a requirement meta model database. Therefore, a new vehicle type can be developed based on the existing vehicle type requirement meta model stored in the requirement meta model database; the development efficiency of the new vehicle type is improved by the scheme of an existing vehicle type design resource and development resources are saved.
