Combinatorial optimization techniques for the design of reconfigurable machines

International audienceThe problem is to design machine modules, such as working positions, turrets and spindle heads, suitable for the given production process. This problem is formulated as a combinatorial optimization problem where a known set of machining operations is partitioned into subsets which are assigned to the pieces of equipment under precedence, in- clusion, exclusion constraints among operations as well as productivity and location constraints. The objective is to minimize the total equip- ment cost. The solution method is based on searching the shortest path in a specific graph
