Method for analyzing and classifying process data that operates a knowledge base in an open-book mode before defining any clusters
First Claim
1. A method of analyzing data relating to parameters of a component in a process plant, a component being a piece of equipment, a location, or a process step, and a process plant being an agglomeration of equipment and/or process steps, the method comprising the steps of:
- a) defining a set of data channels as a data vector for a particular component, each data channel in the set carrying data relating to a specific parameter of the particular component, such that a first data channel of the set carries data relating to a first specific parameter and a second data channel transmits data relating to a second specific parameter, the data vector being a discrete transmission of instantly measured data vector of the set of data channels, each discrete transmission being indicative of an operating condition of the particular component;
b) defining a knowledge base that relates to the particular component;
c) receiving the discrete transmission of the instantly measured data vector into the knowledge base;
d) prior to defining a cluster that encompasses a first data vector for a first operating condition of the particular component in the knowledge base, operating the knowledge base in open-book mode;
e) providing a cluster-generating algorithm that generates an initial cluster from the instantly measured data vector; and
f) adding the initial cluster to the knowledge base, the initial cluster subsequently serving as a pre-defined cluster.

Abstract
Process data mining system and method. The system analyzes data from complex process plants or systems and operates in open-book and closed-book modes. In closed-book mode, the system monitors incoming data sets against pre-defined clusters of data values and generates reports, indicating whether incoming data is a match or a no-match with the pre-defined clusters. In open-book mode, the system generates initial clusters, without having a-priori knowledge of the component or process, and also creates clusters “on the fly”, thereby fine-tuning the analysis. A knowledge base encompasses a combination of parameters for a particular component. Clusters are defined within the knowledge base, each cluster representing a particular operating condition. The system expands clusters, within pre-defined limits, or creates new clusters, as needed, in order to accommodate incoming data values. Newly created clusters are then named, so as to indicate the particular operating conditions.
