Patent ID: 11971796
Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATION
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 5:
6. An information handling system comprising:
one or more processors;
a memory coupled to at least one of the processors;
a set of computer program instructions stored in the memory and executed by at least one of the processors in order to perform actions of:
building a combination model comprising a normal status model and an abnormal status model, wherein the normal status model is built from a set of time-sequenced normal status records and the abnormal status model is built from a set of time-sequenced abnormal status records;
computing a set of time-sequenced coefficient combination values of the normal status model and the abnormal status model based on applying a set of fitting coefficient characteristics to the normal status model and the abnormal status model;
detecting a first status change of a system from a normal status to an abnormal status at a first point in time;
selecting a first one of the time-sequenced coefficient combination values from the set of time-sequenced coefficient combination values based on the first status change and the first
point in time; and

performing goal seek analysis on the system using the combination model and the first one of the time-sequenced coefficient combination values, wherein the combination model analyzes one or more output state values of the system to determine a set of inputs that return the system from the abnormal status back to the normal status.
