To provide a production system creating system that can create production systems of various articles by freely combining a plurality of production factors of various types from a superordinate concept toward a subordinate concept thereof. In the production system creating system, while referring to a point in time when a three-term relationship creates a production system and a point in time when the three-term relationship separates from the production system, a plurality of three-term relationships of various types required for the creation of the production system at an arbitrary point in time are extracted from the relational database 18 and a plurality of production factors of various types corresponding to first to third production factors for forming the extracted three-term relationships are extracted from the factor-type database 17, these three-term relationship extracted from the relational database 18 are integrated, and these production factors extracted from the factor-type databases 17 are connected in series from a superordinate concept toward a subordinate concept thereof according to the integrated three-term relationship to thereby create production systems of various articles at the arbitrary point in time.
