Abstract
A method for generating a predictor of failure of a manufacturing process. The predictor is generated by generating a candidate solution for the predictor and then determining a fitness of the candidate solution using fitness cases pertaining to the manufacturing process and a set of costs associated with the manufacturing process. The fitness may then be used to formulate a next generation of candidate solutions for a design method modeled on evolution.
Claims17
A method for generating a predictor of failure of a manufacturing process, comprising the steps of:
- generating a candidate solution for the predictor;
- determining a fitness of the candidate solution using a fitness case pertaining to the manufacturing process wherein the fitness case includes data obtained at a process step associated with the predictor and data obtained from at least one other process step.
A manufacturing system, comprising:
- a set of process steps including a process step that yields a sub-assembly for a product;
- predictor that predicts an eventual failure of the product in response to a set of process data obtained at the process step that yields the sub-assembly and a set of process data obtained at one or more of the other process steps that yielded the sub-assembly.
A method for manufacturing a product, comprising the steps of:
- performing a set of process steps including a process step that yields a sub-assembly for the product;
- predicting an eventual failure of the product in response to a set of process data obtained at the process step that yields the sub-assembly and a set of process data obtained at one or more of the other process steps that yielded the sub-assembly.
