摘要： PROBLEM TO BE SOLVED: To provide a method for detecting an abnormality in an apparatus or a system. SOLUTION: The method includes: a step of providing a data sample set comprising n measured physical parameter values associated with the apparatus or system generated by repeating a measurement of the physical parameter n times; a step of selecting an extremal parameter value from the data sample set; a step of determining a probability of observing the selected parameter value, where the value of the position parameter and that of the scale parameter are created by an integer value (m) each in which (m), for example indicating the size of a subsample data set having the m measured parameter values logically, is smaller than (n), namely m COPYRIGHT: (C)2009,JPO&INPIT

摘要： A method is provided for detecting an abnormality in an apparatus or system. The method includes: providing a data sample set comprising n values of a measured physical parameter associated with the apparatus or system generated by repeating a measurement of the physical parameter n times; selecting an extremal measured parameter value from amongst the data sample set; determining a probability of observing the selected parameter value by applying the selected parameter value to an extreme value probability distribution function having a location parameter and a scale parameter wherein the value of the location parameter and the value of the scale parameter are each constructed using an integer value m in which m is less than n (i.e. m

摘要： A method is provided for detecting an abnormality in an apparatus or system, such as a jet engine, comprising: ```providing a data sample set comprising n values of a measured physical parameter associated with the apparatus or system, such as vibration amplitude generated by repeating a measurement of the physical parameter n times; ```selecting an extremal measured parameter value from amongst the data sample set; ```determining a probability of observing the selected parameter value by applying the selected parameter value to an extreme value probability distribution function having a location parameter and a scale parameter wherein the value of the location parameter and the value of the scale parameter are each constructed using an integer value m in which m is less than n; ```and conditionally indicating that the selected parameter value is abnormal according to the value of said probability.

摘要： An asset, such as an aircraft engine, operational health monitoring system, in which a plurality of sensors are arranged to determine values of asset operation parameters pertaining to an instance of asset operation. One or more processing unit receives data corresponding to said asset operation values and determine a plurality of asset locations at a corresponding plurality of points in time. The one or more processing unit is arranged to receive data indicative of the location of a region of adverse environmental conditions which may impact on the operation of the asset and to compare the determined locations of the asset with the location of said region so as to determine whether one or more of said asset locations fall within said region. An indicator of operational risk associated with the presence of said asset in said region is output which preferably can drive asset operation or maintenance decision making. The system may be used for ash cloud impact monitoring for assets such as aircraft, a fleet of aircraft or aircraft engines. The region of environmental conditions may be defined as polyhedron or polygons representing different severities including airborne particulate material. The output indicator may be a count of the number of instances of exposure of the asset to adverse environmental conditions.
