Abstract: A system and method for automated adjustment processing using pre-configured sets of business rules is provided. The seller pre-configures a set of business rules for use in processing an adjustment for a specific buyer. The set of business rules may be variable for each buyer and/or globally set. When a payment is received from a seller and an adjustment is required, an adjustment management application retrieves the buyer's set of business rules from the seller. The set of business rules are then applied to attempt to match the received payment to one of the buyer's outstanding invoices. If the match is successful, the buyer's payment is processed.

Abstract: A portable, microprocessor-based test instrument for the calibration, check testing, and checkout of nuclear power reactor systems under simulated operating conditions. The instrument includes a master microprocessor bus having direct communication to interchangeable plug-in printed circuit boards. Applications to which the invention may be put include rod control simulation and analysis, neutron monitoring system analysis, and rod block monitoring system simulation and analysis. The test instrument electronically interconnects at any of a plurality of points within a reactor control and monitoring system. The electrical network from the point of interconnection to the core rods is disabled and the test instrument, receives serial control command signals as would the disabled portion of the network. The test instrument also generates appropriate acknowledgements and response signals. Alternatively, a test instrument can generate faulty response signals to simulate improper command responses.
