FPGA-based implementation of genetic algorithm for the traveling salesman problem and its industrial application

Abstract

In this paper an adaptive distribution system for manufacturing applications is considered and examined. The system receives a set of various components at a source point and supplies these components to destination points. The objective is to minimize the total distance that has to be traveled. At each destination point some control algorithms have to be activated and each segment of motion between destination points has also to be controlled. The paper suggests a model for such a distribution system based on autonomous subalgorithms that can further be linked hierarchically. The links are set up during execution time (during motion) with the aid of the results obtained from solving the respective traveling salesman problem (TSP) that gives a proper tour of minimal length. The paper proposes an FPGA-based solution, which integrates a specialized virtual controller implementing hierarchical control algorithms and a hardware realization of genetic algorithm for the TSP.
