Abstract: A refined after-sale service plays a key role in stimulating purchase of customers, which is similar to a low price, high quality and excellent performances of products. Therefore, more and more manufacturers provide warranty as a kind of after-sale service to consumers. Durable consumption goods such as automobiles and heavy machinery are often sold with a two-dimensional warranty, where their failures can be accounted for by time and usage. This study reviews related researches of two-dimensional warranty management in three aspects, i.e., field reliability modeling, warranty claims forecasting, and warranty policy design. Some directions of future research are suggested in the end.
