Abstract
Words in a requirement may be decomposed into sub-parts to dynamically generate a requirement graph model. The requirement graph model may include nodes for the sub-parts of the requirement. The requirement graph model may be connected to a constraint graph model based on one or more nodes of the requirement graph model. The connection of the requirement graph model to the constraint graph model may form a combined graph model, and analysis may be performed based on the combined graph model.
Claims15
A system for analyzing requirements, the system comprising:
- one or more physical processors configured by machine-readable instructions to:
- obtain requirement information, the requirement information defining a requirement;
- identify sub-parts of the requirement based on words of the requirement;
- generate a requirement graph model of the requirement, the requirement graph model including nodes for sub-parts of the requirement;
- connect the requirement graph model to a constraint graph model based on one or more of the nodes of the requirement graph model corresponding to one or more nodes of the constraint graph model, wherein connection of the requirement graph model to the constraint graph model forms a combined graph model, and is effected via the one or more of the nodes in the requirement graph model that correspond to the one or more nodes of the constraint graph model and the corresponding one or more nodes of the constraint graph model, wherein the combined graph model models outputs of a system's theoretic process analysis corresponding to an unsafe condition or a hazard node;
- and
- perform analysis based on the combined graph model.
