A method for generation of a sequence of operations for a manufacturing process including modeling the manufacturing process through a finite state machine to create a sequence of operations generator operative to generate a list of sequences of operations for the manufacturing process and utilizing the sequence of operations generator to input process information and automatically generate a list of sequences of operations.

Framework for automatic generation of sequence of operations

A method, system, and computer program product for automated root cause identification of a failure of a logic controller have been provided. The method includes receiving logic controller failure information, receiving a logic model of logic code for the logic controller, and mapping the logic controller failure information to the logic model to identify a logic failure model state. The method further includes determining a potential trigger of the failure of the logic controller as a root cause via tracing through at least one path in the logic model to reach the logic failure model state. The method also includes identifying the root cause in the logic code via mapping the root cause from the logic model to the logic code, and outputting the logic code with the identified root cause of the failure of the logic controller.

Automated root cause identification of logic controller failure

A method for generation of a control code set for a manufacturing process includes generating a list of sequences of operations with an automatic sequence of operations generator, selecting an optimized sequence of operations from the list of sequences of operations, and utilizing the optimized sequence of operations to generate the control code set.
