Abstract

An integrated supply chain management with anomaly detection. An order schedule has one or more orders, each of which has a production requirement and a due date. An asset schedule has asset commitments associating assets with orders. Each asset has equipment specifications, including an asset class and one or more operational thresholds. The computer system identifies an asset of a class corresponding to a production requirement of an order and modifies the asset schedule to commit the asset to the order prior to the due date of the order. The computer system receives sensor input for the asset and determines whether an anomaly exists. If so, the computer system commits a second asset to the order.

Claims

1. A computer program product for anomaly detection, the computer program product comprising:

a server computer comprising one or more processors, the one or more processors comprising one or more non-transitory computer-readable storage media and program instructions stored on the one or more computer-readable storage media, the program instructions comprising;

a supply chain program (SCP), an asset management program (AMP) and an anomaly detection program (ADP);

the SCP including program instructions to receive a first order, receive an asset schedule from the AMP, commit a first asset of one or more assets to the first order, the first asset having an asset class corresponding to a first production requirement of the first order, send the first asset commitment to the AMP and the ADP, and modify the asset schedule with the first asset commitment, the first asset commitment associating the first asset with the first order for a period of time prior to a first due date of the first order;

the AMP including program instructions to determine use and availability of the one or more assets and generate the asset schedule, and to send an asset availability update to the SCP and the ADP,

the ADP including program instructions to determine whether a sensor input violates one or more operational thresholds, including to determine a future value of the sensor input, the future value corresponding to a time; and

to determine whether the future value violates an operational threshold of the one or more operational thresholds, and, if so, identify an anomaly of the first asset, send an anomaly report to the SCP and the AMP, the ADP program instructions further including to present to a user at least one of the one or more threshold values and the input, including the future value and the time; and

receive user input, the user input confirming the anomaly;

the SCP further including program instructions to, in response to the asset availability update, adjust the asset commitment of the first asset and send the adjusted asset commitment to the AMP and the ADP; and

the SCP further including program instructions to, in response to the anomaly report, determine a second asset with a production capability corresponding to the first production requirement; and

modify the first asset commitment to associate the second asset with the first order for the period of time prior to the due date of the first order.

2. The computer program product of claim 1, wherein the ADP includes program instructions to:

receive a duration of a corrective action associated with anomaly; and

associate the first asset with a maintenance commitment, the maintenance commitment having a duration at least equal to the duration of the corrective action.

3. The computer program product of claim 1, wherein the SCP includes program instructions to:

receive an asset availability update for a third asset associated with a second order; and

determine whether the asset availability update requires an adjustment to an asset commitment for the third asset and, if so, identify a fourth asset with an asset class corresponding to a second production requirement of the second order and, in response, modify the asset schedule with a second asset commitment, the second asset commitment associating the fourth asset with the second order.

4. The computer program product of claim 1, wherein the program instructions to modify the first asset commitment further comprise program instructions to disassociate the first asset with the first order.

5. The computer program product of claim 1, wherein the ADP includes program instructions to:

receive equipment specifications for each of the one or more assets, the equipment specifications including an asset class and one or more operational thresholds; and

receive the sensor input from one or more sensors, each sensor of the one or more sensors monitoring a measure of a component of the first asset.

6. The computer program product of claim 5, wherein the program instructions to determine whether the sensor input violates one or more operational thresholds further comprise program instructions to:

determine whether the sensor input violates the one or more operational thresholds and, if so, determine a frequency corresponding to the sensor input violating the one or more operational threshold; and

determine whether the frequency exceeds a frequency threshold, the frequency threshold corresponding to the component of the first asset.

7. The computer program product of claim 1, wherein the server computer further comprises a database to maintain one or both of an order schedule and the asset schedule, the order schedule comprising one or more orders, each of the one or more orders comprising a production requirement and a due date, and the asset schedule comprising one or more asset commitments associating one or more assets with the one or more orders.
