Method for determining the time and extent of maintenance operations
First Claim
1. A method for determining timing and scope of maintenance operations for a system having a plurality of maintenance items, said method comprising:
- predefining associated maintenance intervals and tolerance ranges for implementing the maintenance items;
predefining a minimum maintenance interval between an imminent maintenance operation and a subsequent maintenance operation;
establishing a predicted time for a next subsequent maintenance operation, at the latest, at the time of a tolerance range end point which occurs first after expiration of the predefined minimum maintenance interval following the time of a preceding maintenance operation; and
designating as maintenance items to be carried out during the imminent maintenance operation at least those maintenance items whose tolerance range end points occur before the predicted subsequent maintenance time.

Abstract
In a method for defining the time and scope of maintenance operations for a system having a plurality of maintenance items, each of which should be carried out within an assigned tolerance range, a minimum maintenance interval between successive maintenance operations is predefined. The timing of a maintenance operation is predictively fixed at at least that tolerance range end point which is the first of the tolerance range end points of maintenance items relating to maintenance times to follow the time of a preceding maintenance operation while complying with the minimum maintenance interval. At least those maintenance operations whose tolerance range end points occur before the predicted subsequent maintenance time are defined as the scope of the imminent maintenance operation.
