Abstract
Various systems and methods for modeling a manufacturing assembly line are disclosed herein. Some embodiments relate to operating a processor to receive cell data, extract feature data from the cell data, determine a plurality of faults, determine a priority level for each fault by applying the extracted feature data to a predictive model, determine at least one high priority fault, and generate at least one operator alert based on the at least one high priority fault.

A method for assessing faults in a manufacturing assembly line, the manufacturing assembly line comprising a plurality of cells, each cell being configured to successively process a workpiece along the manufacturing assembly line, the method comprising operating a processor to:
- receive cell data associated with at least one cell of the manufacturing assembly line, the cell data comprising, for each cell, at least one input state of that cell and a cell position of that cell within the manufacturing assembly line;
- extract feature data from the cell data, the feature data comprising at least one input state and at least one a cell position of at least one cell;
- determine a plurality of faults, each fault corresponding to one cell;
- determine whether at least one fault of the plurality of faults comprises a defective workpiece fault;
- for each defective workpiece fault,
- generate a scrap workpiece cost associated with the defective workpiece fault;
- determine whether the defective workpiece fault can be remedied with a cell within the plurality of cells configurable as a rework cell for remedying manufacturing faults;
- and
- in response to determining the defective workpiece fault can be remedied with a rework cell, generate a rework workpiece cost associated with the defective workpiece fault;
- apply the extracted feature data, the scrap workpiece cost, and the rework workpiece cost to a predictive model generated for predicting a production level of the manufacturing assembly line to determine a priority level for each fault and a recommendation for each defective workpiece fault, the recommendation comprising one of a rework recommendation to use the rework cell for remedying the defective workpiece fault and a scrap recommendation to discard the defective workpiece;
- determine at least one high priority fault from the plurality of faults based on the priority level for each fault;
- determine whether the at least one high priority fault comprises a defective workpiece fault;
- and
- in response to determining that the at least one high priority fault comprises a defective workpiece fault, generate at least one operator alert based on the at least one high priority fault and the recommendation for the defective workpiece fault;
- otherwise, generate at least one operator alert based on the at least one high priority fault.

- otherwise, generate at least one operator alert based on the at least one high priority fault.
