Abstract:For a variety of products or customers ordering strategy in supply chain,three models of the ordering strategy including single ordering strategy, joint ordering strategy, carry ordering strategy are established,and so do three total costs functions of the ordering strategy.Analysis of the three ordering strategies aggregation effects show that carry ordering strategy carries the aggregation effects much better than the joint ordering strategy, and joint ordering strategy carries the aggregation effects better than the single ordering strategy; when additional ordering costs in the total ordering costs accounts for a large proportion, carry ordering strategy will minimize the total costs, and aggregation effects is obvious; when additional ordering costs accounts for a small proportion in the total ordering costs,carry ordering strategy becomes unfeasible, and the joint ordering strategy will cost less.
