Outline of Final Research Achievements

We targeted at communication protocol FlexRay and studied an IVNS synthesis technique which reduces a fabrication cost. Our synthesis technique optimally determines a wire harness and FlexRay design parameters under real-time and reliability constraints so that we obtain an optimal IVNS whose fabrication cost is minimal. Design Automation in IVNS's contributes to reducing a development cost as well as design optimization contributes to reducing a fabrication cost.
