Abstract: Finding out the optimal inventory control policy for Assemble-to-Order (ATO) system is an important task in the field of inventory control.Due to the complexity of its structure,there are only clear conclusions in some very special cases.For a wide range of ATO systems,the optimal and asymptotically optimal inventory control policies under different conditions were obtained,and the methods were extended to ATO systems with general BOM structures.Taking the W-type and M-type systems which were commonly used in the study of ATO system inventory control as examples,the simulation analyses showed the effectiveness of the above inventory control policies.Compared with the classical policy and the latest control based on stochastic programming,the W-type ATO system using the above inventory control policy would reduce the total inventory cost by up to 65% and 23.5%,while the M-type ATO system would reduce the total inventory cost by up to 12.2% and 4.3% respectively.
