%X In this paper, considering the force of market and censored data, we make a study on an improved likelihood method on estimating product-life-function, and we apply it to practice. The study not only can overcome the difficulties and drawbacks in the existing methods of estimating market-life of product, but also provide a new method and procedure for decision makers.
