Simulation on order allocation within multi-suppliers of industrial cluster

The downstream enterprises of supply chain usually order same kind of products from several suppliers within an industry cluster. Two different order allocation strategies considering production status are studied in this paper. The respective order allocation models of a manufacturer with multiple suppliers based on either the production capacity or production load equilibrium are proposed. Considering the uncertainty of demand and enterprises' production capacity, the discrete event system simulation is used to verify that the production load equilibrium-based strategy can not only guarantee the order's on-time delivery from the perspective of the available manufacturing resources, but also lead to promote the whole supplier group's operation level, so as to realize the optimization of the entire supply chain.
