Classification: CPC G | IPC G

Claim 0:
1. A system, comprising:
a memory that stores executable components and work order data defining closed work orders for maintenance tasks that have been completed; and
a processor, operatively coupled to the memory, that executes the executable components, the executable components comprising:
a clustering component configured to cluster the work order data into groups of work orders corresponding to respective types of maintenance operations;
a z-scoring component configured to apply, for a group of work orders of the groups of work orders, statistical analysis that identifies one or more features of a work order, included in the group of work orders, that are anomalous relative to corresponding one or more features of other work orders included in the group of work orders;
a holistic anomaly detection component configured to
determine, based on application of a machine learning algorithm to the closed work orders, boundaries of a multi-dimensional feature space within which values of a combination of more than two features of the closed work orders are typically located, and
determine whether values of the combination of more than two features for the work order deviate from the multi-dimensional feature space;

a risk score component configured to generate a risk score for the work order based on a number of the one or more features that are anomalous, identities of the one or more features, and a determination of whether the values of the combination of more than two features of the work order deviate from the multi-dimensional feature space, and to assign a risk level to the work order based on the risk score; and
a user interface component configured to generate and render a work order report that displays the risk level for the work order.
