| Abstract: | Subgradient optimization is employed to solve the problem of assigning tools to machines in a flexible manufacturing system (FMS). Machines in the FMS have a limited number of slots in the tool magazine, and tools may require multiple slots. Tools are grouped based upon a pairwise similarity coefficient that indicates the frequency of successive operations that require both tools. Typical solution strategies have included graph theoretic heuristics. Lagrangian relaxation is utilized in the algorithm developed in this article. |
