Bid-price control is a popular method for controlling the sale of inventory in revenue management.It is well known that the network capacity control problem can be formulated as a dynamic programming model.In this paper,we approximate the optimal dynamic programming value function with an affine function of the state vector and develop our model based on the flight segment demands.We show that the resulting problem is the deterministic linear programming(DLP) for computing network bid-prices.The DLP yields ...
