We present an approximation algorithm for network revenue management problems. In our approximation algorithm, we construct an approximate policy using value function approximations that are expressed as linear combinations of basis functions. We use a backward recursion to compute the coefficients of the basis functions in the linear combinations. If each product uses at most L resources, then the total expected revenue obtained by our approximate policy is at least 1/(1+L) of the optimal total expected revenue. In many network revenue management settings, although the number of resources and products can become large, the number of resources used by a product remains bounded. In this case, our approximate policy provides a constant-factor performance guarantee. Our approach can incorporate the customer choice behavior among the products and allows the products to use multiple units of a resource, while still maintaining the performance guarantee.
This is joint work with Yuhang Ma (Cornell), Paat Rusmevichientong (USC) and Mika Sumida (Cornell).
