Fecha de publicación: 20/06/2013 Fuente: WIPO "sustainability" PURPOSE: An obsolescence prediction tool is provided to supply a component stock-out date for various parts, a part form, a fraction part, a replaceable line unit, and an entire system, thereby supplying a data-driving date which is influenced to an operation of the system. CONSTITUTION: A data integrator(102) receives part information(106) for parts. The part information includes fault data for the parts, stock level data, the final lifetime date data, and the final repair date data. A sustainability optimization device(108) receives a sustainability condition for the parts. The sustainability condition is selected from a group which comprises part stock amount, part expenses, etc. A predictor(112) is connected to the data integrator and the sustainability optimization device and analyzes the part information and the sustainability condition.
