Abstract：The configuration problem of multi-echelon supply chain with limited production capacity is dis-cussed .Based on the relationship of safety stock with respect to both the production capacity and net re-plenishment time , the supplier selection and the corresponding service times are optimized .A mixed inte-ger programming model has been proposed for solving the supply chain configuration problem under uncer -tain market demands and limited production capacity , while an improved Genetic Algorithm with higher so-lution precision is adopted for problem solving .Two observations have been obtained from the results . First, a supply chain should avoid selecting those suppliers with smaller remaining capacities yet without advantageous prices and service times .Second , in case of highly fluctuated demands , a supply chain should allow broader lead time ranges for suppliers to achieve lower SCC ( supply chain configuration ) cost.
