Research on distribution network of supply chain with grey demands

There are various types of grey information in distribution network of supply chain, which are helpful to improve practical usefulness of distribution. In this paper, grey demands existed in supply chain have been discussed, and an optimization model of distribution network with grey demands is proposed. The model is NP-hard, and a hybrid particle swarm optimization algorithm based on grey chance-constrained programming is proposed to solve it. The results of example show that the model and the algorithm are effective for dealing with distribution problem of supply chain with grey demands.
