Optimization of modular machining lines

The paper summarizes the main results of the author’s Ph.D. thesis presented in December 2006 at the école des Mines de Saint étienne. The work was supervised by Alexandre Dolgui and Xavier Delorme. The thesis is written in French and is available upon request from the author. Its purpose is to provide decision support in the design and reconfiguration of modular machining lines with multi-spindle units. This design problem is defined as the selection of spindle units to perform a set of operations needed to produce the parts and subsequently their assignment to workstations. The corresponding optimization problem is solved using different models based on integer and constraint programming.
