Model for Silicon Piece Manufacturing Process Planning Based on Polychromatic Sets Theory

Polychromatic sets theory is summarized. Based on the study of process demand for silicon piece manufacturing and process sequence, the polychromatic sets theory was applied to construct the mathematical model of silicon piece process planning. The model was comprised of contour matrix and polychromatic graph, which were respectively used to describe the process demand for silicon piece manufacturing and the interaction among working procedures. According to this model, the logical sum or logical product of sets theory was applied to solve reasonable process routing, and then take a customer order demanding as an example, the established model and solution were confirmed.
