Abstract

A method includes obtaining information identifying a predicted trajectory of material-based measurements associated with a transfer of material. The method also includes obtaining actual material-based measurements during the transfer of the material and determining whether the actual material-based measurements fall outside of the predicted trajectory. The method further includes identifying a problem with the transfer of the material if at least one of the actual material-based measurements falls outside of the predicted trajectory. The method may also include generating the predicted trajectory of the material-based measurements using historical data associated with one or more prior transfers, such as historical data associated with at least one pump to be used during the transfer of the material. The actual material-based measurements could include measurements of a level and/or a volume of the material in a tank.

Claims

using at least one processing device;

obtaining information identifying a predicted trajectory of material-based measurements associated with a transfer of material;

obtaining actual material-based measurements during the transfer of the material;

determining whether the actual material-based measurements fall outside of the predicted trajectory; and

identifying a problem with the transfer of the material if at least one of the actual material-based measurements falls outside of the predicted trajectory;

wherein the predicted trajectory is defined by first and second margins identifying a range of acceptable material-based measurements over time; and

wherein determining whether the actual material-based measurements fall outside of the predicted trajectory comprises determining whether each actual material-based measurement falls outside of the range of acceptable material-based measurements.

2. The method of claim 1, wherein the actual material-based measurements comprise at least one of:

measurements of a level of the material in a tank and measurements of a volume of the material in the tank.

3. The method of claim 1, further comprising:

generating the predicted trajectory of the material-based measurements using historical data associated with one or more prior transfers.

4. The method of claim 3, wherein generating the predicted trajectory comprises generating the predicted trajectory using historical data associated with at least one pump to be used during the transfer of the material.

5. The method of claim 1, wherein obtaining the information identifying the predicted trajectory comprises receiving information associated with the predicted trajectory using a graphical user interface configured to receive input from a user.

6. The method of claim 1, further comprising:

generating a score based on (i) how well the actual material-based measurements remain within the range of acceptable material-based measurements and (ii) a size of a difference between the first and second margins.

7. The method of claim 1, further comprising:

presenting the predicted trajectory and the actual material-based measurements to a user.

8. An apparatus comprising:
