Abstract: A method for determining if a proposed color solution, such as paint, pigments, or dye formulations, is acceptable, is provided. The inputs to the system are the actual color values of an item, differential color values, a proposed color solution, and second color values associated with the proposed color solution. The system includes an artificial intelligence model to analyze the inputs and produce an output for communicating whether the proposed color solution is acceptable. The artificial intelligence model may be embodied in a neural network.

Abstract: A computer based system and method provides color solutions to a customer. A solution request from an operator located at a remote location is received and delivered to a central location over a computer network. A composite solution database is searched to determine a color solution as a function of the solution request.

Abstract: A change tracing system detects and records changes made to data items by processes in a computer system. Processes and changes are organized as change sessions in a change history database and tagged with user-provided reasons and other identification fields. A query module provides detailed access to change history and selection of specific changes and items in order to analyze effects of changes, diagnose problems caused by changes, compare changes and change history, rollback from changes to previous item contents or package sets of changes to be repeated. Linkage between data items is recorded in order to document the impact of changes affecting dependent data items. Alerts and copies of change sessions may be transmitted automatically to designated users. Communication between change tracing systems running on networked computers detects and records remotely caused changes on the system where the data item resides as well as the system originating the change.

Abstract: system and method for determining if a proposed color solution, such as paint, pigments, or dye formulations, is acceptable, is provided. The inputs to the system are the color values of a proposed paint or other color formulation and differential color values. The system includes an input device for entering a proposed color solution and an artificial intelligence tolerance model coupled to the input device. The tolerance model produces an output signal for communicating whether the proposed color solution is acceptable. The artificial intelligence model may be embodied in a neural network. More specifically, the tolerance model may be a back propagation neural network.
