Applications to stochastic lot-sizing problems will be discussed. This is joint work with Yongpei Guan and George Nemhauser and is based on the following two papers (preprints of the papers are available at \u003Ca href=\u0022http:\/\/www2.isye.gatech.edu\/~sahmed\/publications.html\u0022 title=\u0022http:\/\/www2.isye.gatech.edu\/~sahmed\/publications.html\u0022\u003Ehttp:\/\/www2.isye.gatech.edu\/~sahmed\/publications.html\u003C\/a\u003E):\n\u003C\/p\u003E\n\u003Cp\u003EY.
