Abstract:
A method of monitoring a process having a plurality of input parameters, each parameter having respective variation range and taking a value within said respective variation range, and said process having at least one output parameter, the method comprising:dividing said variation ranges of said input parameters into sub-ranges, obtaining a series of input values for each of said input parameters, said input values respectively falling into respective ones of said sub-ranges, representing each input value by its corresponding sub-range, obtaining a corresponding series of output values for said at least one output parameter, for each one of input states of said system, each input state comprising corresponding values for each of said input parameters, recording an association of a combination of sub-ranges with values of said at least one output parameter corresponding to said input state, from said associations constructing a statistical model relating said sub-ranges of said plurality of input values of said input state with said output values and using said statistical model to predict output behaviour of, said process in terms of said input states.
