Abstract
A method, computer program product, and system for handling an error that occurs during processing of a job in a manufacturing system are provided. The method, computer program product, and system provide for determining a first location in the job where a first subsystem of the manufacturing system is currently processing, identifying a second location in the job where a second subsystem of the manufacturing system completed processing before the error occurred at the second subsystem, the second subsystem being connected in series to and downstream from the first subsystem, and providing a controller-generated repositioning instruction for the first subsystem based on the first location and the second location.
Claims28
A method of handling an error that occurs during processing of a job in a manufacturing system, the method comprising:
- determining a first location in the job where a first subsystem of the manufacturing system is currently processing in response to detecting the error at a second subsystem;
- identifying a second location in the job where the second subsystem of the manufacturing system completed processing before the error occurred at the second subsystem, the second subsystem being connected in series to and downstream from the first subsystem to process the second location after the first subsystem has completed processing the second location;
- and
- providing a controller-generated repositioning instruction for the first subsystem based on the first location and the second location to restart at a location in the job where the error occurred in the second subsystem.
A computer program product comprising a computer readable medium, the computer readable medium including a computer readable program for handling an error that occurs during processing of a job in a manufacturing system, wherein the computer readable program when executed on a computer causes the computer to:
- determine a first location in the job where a first subsystem of the manufacturing system is currently processing in response to detecting the error at a second subsystem;
- identify a second location in the job where the second subsystem of the manufacturing system completed processing before the error occurred at the second subsystem, the second subsystem being connected in series to and downstream from the first subsystem to process the second location after the first subsystem has completed processing the second location;
- and
- provide a controller-generated repositioning instruction for the first subsystem based on the first location and the second location to restart at a location in the job where the error occurred in the second subsystem.
A manufacturing system comprising:
- a first subsystem operable to process a job;
- a second subsystem connected in series to and downstream from the first subsystem, the second subsystem being operable to process the job, wherein the second subsystem is further operable to process a portion of the job after the first subsystem completes processing the portion of the job;
- and
- one or more controllers operable to handle an error that occurs during processing of the job at the second subsystem, including:
- determine a first location in the job where the first subsystem is currently processing in response to detecting the error at the second subsystem;
- identify a second location in the job where the second subsystem completed processing before the error occurred at the second subsystem;
- and
- provide a controller-generated repositioning instruction for the first subsystem based on the first location and the second location to restart at a location in the job where the error occurred in the second subsystem.
