Intelligent agent system and method for evaluating data integrity in process information databases
View Patent ↗A data integrity module and method for evaluating data in a process information database. A neural network generates statistical patterns for specifying patterns for the data being evaluated. A fuzzy expert rules base specifies rules for evaluating the data. A processor, responsive to the rules base and the statistical patterns, identifies suspect data in the process information database by evaluating the data according to the rules base and the statistical patterns. A modification system modifies the suspect data in the process information database.
1. A data integrity system for evaluating manufacturing data, said system comprising:
an evaluation resource cooperatively associated with reference information, said reference information relating to patterns within manufacturing data or rules for evaluating the manufacturing data, said manufacturing data being generated by a manufacturing process;
a processor, responsive to the reference information, for accessing the manufacturing data and for evaluating the accessed manufacturing data according to the reference information, the processor identifying suspect manufacturing data in the evaluated manufacturing data; and
a modification subsystem responsive to the processor for modifying at least some of the suspect manufacturing data.
2. The system of claim 1 wherein the modification subsystem modifies certain identified suspect manufacturing data according to pre-set instructions.
3. The system of claim 2 wherein the processor requests user intervention to modify other certain identified suspect manufacturing data which is not modified by the modification subsystem.
4. The system of claim 1 wherein the processor requests user intervention to modify certain identified suspect manufacturing data.
5. The system of claim 4 further comprising a user access subsystem for permitting a user to modify the certain identified suspect manufacturing data.
6. The system of claim 1 further comprising a user access subsystem for permitting a user to modify certain of the identified suspect manufacturing data.
7. The system of claim 1 further comprising a marking subsystem for marking evaluated manufacturing data as one or more of the following: suspect when its accuracy is inconsistent with the reference information; auto-corrected when suspect manufacturing data has been corrected without user intervention; user-corrected when the suspect manufacturing data has been corrected by the user; and/or checked when its accuracy is consistent with the reference information.
8. The system of claim 1 further comprising a process information database storing the manufacturing data generated by the manufacturing process, and wherein the process information database comprises one or more of the following: a raw materials database, a waste and delay database, a productivity database, a quality database and a machine process database.
9. The system of claim 1 wherein the manufacturing process produces a product including one or more of the following products or parts therefor: pharmaceuticals, automobiles, food and beverage, pulp and paper, injection molded items, electronics, and printed items.
10. The system of claim 1 , wherein the reference information comprises statistical patterns for the manufacturing data.
11. A method for evaluating data integrity in a process information database having manufacturing data, said method comprising:
providing reference information, said reference information relating to patterns within manufacturing data or rules for evaluating the manufacturing data, said manufacturing data being generated by a manufacturing process;
accessing the manufacturing data stored in the process information database;
evaluating the accessed manufacturing data according to the reference information;
identifying suspect manufacturing data in the evaluated manufacturing data; and
modifying at least some of the suspect manufacturing data in the process information database.
12. The method of claim 11 further comprising modifying certain identified suspect manufacturing data according to pre-set instructions.
13. The method of claim 11 further comprising requesting user intervention to modify certain identified suspect manufacturing data.
14. The method of claim 13 further comprising permitting a user to modify the certain identified suspect manufacturing data.
15. The method of claim 11 wherein the manufacturing process produces a product including one or more of the following products or parts therefor: pharmaceuticals, automobiles, food and beverage, pulp and paper, injection molded items, electronics, and printed items.
