Abstract: In Mass Customization（MC）, customized product’ cost depends on customization degree and postponement strategy. As to Customized modules which have multi-customer Order Decoupling Points（CODP） and are all differentiated by postponement, a customized module’s production and logistics supply chain pattern is built, and module’ multi-echelon inventory system long-run average costs structural model and total customization costs model are presented. Then, considering the complexity of evaluating multi-echelon systems, the Adaptive Genetic Algorithm（AGA） is proposed. This AGA denotes gene with real number, adopts rank-based fitness assignment, designs adaptive crossover rate and adaptive mutation rate by individual fitness, and adaptive mutation operator by mutation temperature at the same time. Customized module’s production and logistics supply chain pattern and customization costs computation can help enterprises select appropriate customization level and postponement strategy. At last, an illustrative example is given.
