Abstract: The present invention searches for, in order of priority, a combination of material property parameters having a significant relationship, from among arbitrary combinations of multiple material property parameters. The present invention comprises a database stored in a storage device, a graph generation step, a graph search step, and a prioritization step, wherein the database stores multiple pairs of material property parameters having mutual relationship; the graph generation step includes generating a graph in which the multiple material property parameters stored in the database are represented as nodes, and inter-node spaces corresponding to the respective material property parameter pairs each being stored as having a relationship therebetween are represented as edges; the graph search step includes searching the graph on the basis of a given search condition and presenting multiple related material properties or inter-material property relationship paths representing relationships between material properties; and the prioritization step includes obtaining, by using information about one or both of the nodes and the edges, priority for the presented multiple related material properties or inter-material property relationship paths, and outputting a result in the descending order of priority.

Abstract: Provided are a search system and a search method capable of searching an unknown combination of material property parameters having a significant relationship based on already known relationships from among multiple arbitrary combinations of material property parameters. The search system includes a database, a graph generator, and a graph searcher, and is configured as follows: the database stores the plurality of pairs of material property parameters having mutual relationships, and the graph generator generates a graph in which material property parameters stored in the database are nodes, and an inter-node corresponding to the pairs of material property parameters stored to have mutual relationships is an edge. The graph searcher searches the graph generated by the graph generator based on a given search condition and outputs a search result.
