    摘要: A computerized system for analyzing information associated with a process unit. A database contains historical information relating to previously compiled information. A secure input receives criteria from a restricted source. A computer mathematically determines a limit based upon the criteria. An open input receives the information associated with the process unit from multiple test locations. A compiler selectively adds to the database of historical information the information. The computer also selects at least a portion of the information based upon selection criteria. In addition, the computer manipulates the selected information based upon manipulation criteria. The manipulated information is compared against the limit. An output indicates a first disposition of the process unit when the manipulated information violates the limit. The output indicates a second disposition of the process unit when the manipulated information does not violate the limit.
