  • RBF approach for trajectory interpolation in self-organizing map based condition monitoring

    Publication Year: 1999, Page(s):1003 - 1010 vol.2
    Request permission for commercial reuse | Click to expandAbstract |PDF file iconPDF (948 KB)

    Self-organizing map trajectory interpolation using radial basis functions is proposed for process condition monitoring. Self-organizing maps are a powerful means to visualize the state of a process. However, a quantization process takes place when input vectors are mapped onto the grid (output) space. The discrete nature of the output space gives rise to a considerable loss of information which is... View full abstract»

    We describe a novel approach for shop poor control combining a distributed multi-agent structure and computational intelligence techniques. Shop floor activities are controlled by a network of autonomous agents. Each agent makes its decision with a fuzzy algorithm evaluating all the alternative actions with multiple criteria based on real time measures of shop's conditions. A tuning mechanism of t...
