A device and a method for predicting the mean time period between two failures of a technical system, for example a manufacturing system or an assembly system for motor vehicle components. The device includes a components list (130.1, 130.2). Those components of the technical system which are included in this components list are the maintenance-intensive components. Every failure of a component of the list leads to a failure of the system. Furthermore, the device includes an apparatus for acquiring setpoint MTBF values of all the components of the list. A setpoint MTBF value of a component is a requested or planned mean time period between two failures of this component. The apparatus predicts the planned mean time period between two failures of the technical system as a function of the setpoint MTBF values of the components.
A method for predicting a mean time period between two failures of a technical system, an electronic components list being predefined, the electronic components list comprising maintenance-intensive components of the technical system in which each failure of a component of the components list leads to a failure of the system, the method comprising the following steps carried out using an electronic data processing system:
