In this paper, a multi-depot vehicle routing problem with weight-related cost (MDVRPWRC) is discussed. It is an extension of the classical multi-depot vehicle routing problem (MDVRP) by treating the vehicle load, i.e. the total weight of freight in a vehicle, as a variable in the objective of model. The corresponding costs incurred by the vehicle load are considered in the objective function when...
In this paper, a low-complexity power-efficient iterative detection scheme for differentially encoded MPSK transmission over AWGN and Rayleigh fading channels is presented. As the main contribution, a novel APP coherent demodulator, which well suits for iterative processing, is derived under the optimal bit-based MAP criterion. The implementation of iteration is not trellis-based, and needn’t reconstruct...
