Aggregated prognosis deviation determining method for product, involves aggregating prognosis deviation in pre-defined surrounding, and implementing prognosis deviation in error determination

摘要

The method involves aggregating a prognosis deviation in a pre-defined surrounding, and implementing the prognosis deviation in an error determination. The aggregated prognosis deviation is determined, while the aggregated prognosis deviation is related on a complete history of a viewed period. A profile range between a prognosis curve (16) and a history curve (14) is compared for a period for providing an error value. The prognosis deviation is computed for an ex-post-prognosis. Independent claims are also included for the following: (1) a method for selecting prognosis from a number of prognoses (2) a device for determining an aggregated prognosis deviation (3) a computer program comprising program code units to perform a method for determining the aggregated prognosis deviation.
