The invention relates to the technical field of
engineering design management, in particular to a water conservancy design
decision support system based on a
knowledge graph, which comprises a parameter constraint construction module, a
design standard fusion module, a task semantic affiliation module, a path screening closing module and a structure combination response module. According to the method, logic linkage organization among structure parameters is realized by constructing a
parameter control path and combining with multi-relationship identification among structure nodes, a cross relationship judgment mechanism among standard terms is utilized, the constraint identification capability on the
structure control path is enhanced, and the
structure control path is identified by combining with an index relationship of task semantic tags. Structural path screening has semantic
guiding characteristics, a continuity judgment method of a
closed path is adopted, structural matching precision of path screening is optimized, logic is constructed by using response of a structural combination relation, collaborative adaptability among multiple structures is improved, a linkage path with continuity and logical attachment characteristics is established, and the structural path screening efficiency is improved. And the logic integrity and response coordination of water conservancy design are improved.
