Sheet metal processing is one of popular machining technique. In sheet metal processing, the parts are cut from sheet metal as many as possible in order to reduce the waste of material. The parts cut from sheet metal are processed by the given due date. In order to keep due date, scheduling is important. The optimization of cutting layout and that of schedule are called nesting and scheduling, respectively. The relation between them often become a trade-off. In order to enhance the efficiency of entire manufacturing activities, they should be considered simultaneously.
In this study, therefore, we propose an environment-adaptive GA based nesting scheduling method. We consider nesting and scheduling as different environments, and the cutting layout and the processing order of parts evolve under each environment by using genetic algorithm.
