1. A method of forecasting maintenance of a machine, comprising:
- measuring a parameter of the machine, the parameter being indicative of a condition of the machine;
transferring the measured parameter to a maintenance planning system;
predicting two or more parameter variation curves indicating the variation of the parameter over time, each parameter variation curve representing values of the parameter at a different confidence level; and
identifying a first time period for maintenance of the machine based on the two or more parameter variation curves.

Abstract
A method of forecasting maintenance of a machine is disclosed. The method includes measuring a parameter of the machine, the parameter being indicative of a condition of the machine, and transferring the measured parameter to a maintenance planning system. The method also includes predicting two or more parameter variation curves indicating the variation of the parameter over time, each parameter variation curve representing values of the parameter at a different confidence level. The method further includes identifying a first time period for maintenance of the machine based on the two or more parameter variation curves.

14. A method of scheduling maintenance of a group of machines, comprising:
-
forecasting two or more failure times for each machine of the group of machines based on a measured parameter of the machine; identifying a time period between the two or more failure times for each machine; identifying a second time period as the period of time where the time periods of two or more machines of the group of machines overlap; scheduling maintenance of the two or more machines during the second time period. - View Dependent Claims (15, 16, 17)

18. A maintenance forecasting system for a group of machines comprising;
-
a sensor located on each machine of the group of machines, the sensor being configured to measure a parameter indicative of a condition of the machine; a control system receiving the parameter from each machine of the group of machines, the control system being configured to analyze the parameter and display results, the results including, predicted time periods of failure for each machine of the group of machines, the predicted time period being a period of time when failure of the machine may occur; and a recommended maintenance time period, the recommended maintenance time period being a period of time when the predicted time periods of two or machines of the group of machines overlap. - View Dependent Claims (19, 20)
