1. A machine management system, comprising:
- one or more sensors arranged to take readings of one or more operating variables for a machine;
data processing equipment arranged to receive data indicative of said operating variable readings for the machine and analyse the received operational data to determine a probability distribution there-for,wherein the processing equipment comprises one or more modules of machine-readable code for assigning a value to one or more Stable distribution parameters in dependence on the received operational data, and a departure in the machine operation from a predetermined normal operating condition is determined from the assigned distribution parameter.

Abstract
A machine management system, including one or more sensors arranged to take readings of one or more operating variables for a machine. Data processing equipment is arranged to receive data indicative of said operating variable readings for the machine and to analyse the received operational data to determine a probability distribution there-for. The processing equipment includes one or more modules of machine-readable code for assigning a value to one or more Stable distribution parameters in dependence on the received operational data, and a departure in the machine operation from a predetermined normal operating condition is determined from the assigned distribution parameter.

13. A method of determining an abnormality in the operation of a machine, comprising:
-
receiving data indicative of operating variable readings for the machine; analysing the received operational data to determine a probability distribution there-for, approximating the probability distribution by way of a Stable distribution by assigning a value to a plurality of Stable distribution parameters in dependence on the received operational data, and determining a departure in the machine operation from a predetermined normal operating condition based upon the assigned distribution parameter value. - View Dependent Claims (14, 15)
