The invention relates to a method for the computer-aided forecasting of future operating states of machine components that makes it possible to predict reproducibly and with a high degree of certainty a forthcoming event in the life cycle of a machine component. For this purpose, a parameter that is representative of the state of a machine component under consideration is selected for the component and is acquired as a measured value in the course of the use of the machine component. While taking into consideration the application concerned for which the machine component is being used, the acquired measured value is fed into an automatically running process to find a recommendation for action. Properties and the influencing variables determining these properties, the applications coming into consideration for them, the influencing variables to which the machine component is exposed in the respective application and the resultant influencing variables have in this case been formulated and determined for the machine component under consideration, and these influencing variables should be considered in the interpretation of the acquired measured value and the recommendation for action deduced from it. Findings obtained during the use of the machine component with respect to the influencing variables or findings pertaining to them that have been obtained by systematic experimental investigations are used to ascertain the interactions and effects of the influencing variables and bring them into a relationship with the damage events determined. The items of information ascertained in relation to the interactions and the damage events influenced by them are fed into a database. The application, the acquired measured value and the assigned influencing variables are fed as input variables into a selection algorithm running on a computer which, taking into consideration the input variables and the acquired measured value, selects the recommendation for action that is optimally appropriate for the use in the respective application on the basis of the information stored in the database. |
