Production system creating system and production system creating method

A production system creating system for creating a production system of an article from a combination of production factors branching from a superordinate concept toward a subordinate concept, wherein the production factors are linked with each other by an upper/lower two-term relationship between an arbitrary first production factor and a second production factor lying just below it and also linked with each other by an upper/lower three-term relationship among the first and second production factors, and a third production factor lying just below the second production factor, and the system is provided with a factor-type database for storing a plurality of the production factors of different types, and a point in time when the production factors create the production system and a point in time when the production factors separate from the production system;

• and a relational database for storing a plurality of the two-term relationships of different types and a plurality of the three-term relationships of different types, and a point in time when these two-term relationships and three-term relationships create the production system and a point in time when they separate from the production system, and uses these production factors to execute production system creating means for creating production system at an arbitrary point in time from the past to the present corresponding to various articles,
• wherein the production system creating means refers to the point in time when the three-term relationship creates the production system and the point in time when the three-term relationship separates from the production system to extract from the relational database a plurality of the three-term relationships of various types required for the creation of the production system at the arbitrary point in time and to extract from the factor-type database a plurality of production factors of various types corresponding to the first to third production factors for forming the extracted three-term relationships, integrates these three-term relationships extracted from the relational database;
• and connects in series these production factors extracted from the factor-type database 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.
