Conventional revenue management models assume that demand parameters used for developing the control policy are already known. The optimality of the control policy, however, is often compromised when the real parameters deviate from their estimates. This article considers robust price-control for managing perishable products. It allows uncertain demand parameters whose distributions may be arbitrary. We formulate the stochastic control problem as a continuous-time model. Under fairly general conditions, we derive the optimality condition for the control policy and develop a recursive procedure for the optimal solution. We further examine structural properties of the solution and managerial insights they imply. Numerical results show that the proposed robust model outperforms the conventional benchmark model. In particular, it significantly reduces the variation in revenues without sacrificing the average revenue.
