Abstract:An ordered-specimen cluster analysis based optimization method is proposed for the widely scattered and utterly disordered body electrical devices connection with local networks. First, cCompletely distributed body electrical system with hierarchical subnet architecture is proposeddescribed. Through electrical device reduced-dimension ordering, the optimization problem is converted to the ordered-specimen optimized partitioncluster with limited -capacity problem under consideration of network schedulable condition. Model’s solver algorithm is also proposed using the global search method. Finally, tThe optimization method is used during the development of the completely distributed body electrical system on one prototype vehicle and is proved to be feasible.
