| Abstract: | The newsboy problem has always been an important issue in inventory management.The exiting substitutable newsboy models always describe and measure demand with probability and distribution function.However,in reality,it is often difficult to exactly characterize the demand.This paper considers the online newsboy problem with one-way substitution and unknown demand information.It presents an online order strategy for this problem with a matching optimal competitive ratio.The numerical example demonstrates th... |
