#### چکیده انگلیسی

Newsboy problems have always been an important issue in inventory management. A number of methods have been proposed to solve such problems based on different objectives or considerations. Different from the existing studies, this paper presents a newsboy model with a simple reservation arrangement by introducing the willingness rate, represented as the function of the discount rate, into the models. Mathematical models are developed, and the solution procedure is derived for determining the optimal discount rate and the optimal order quantity. Through the numerical example, we demonstrated the varied profits yielded from the models considering the reservation arrangement, depending on the number of consumers who accept the reservation policy. The profits derived are greater than those from the classical newsboy model, due to the consideration of the reservation.

#### نتیجه گیری انگلیسی

A newsboy problem with a simple reservation arrangement is presented in this paper. A special discount rate is given to the consumers who make a reservation for the product. The willingness rate is the function of the discount rate to represent the proportion of the consumers having a desire to make a reservation. The model is then formulated to maximize the total expected profit. In the solution procedure, the optimal order quantities for the reservation and the usual sales depend on the willingness rate, when the parameter values, like those in the classical newsboy model, are known. The decision variable of the discount rate in the model is critical, since the willingness rate is the function of a discount rate. The optimal total order quantity in the proposed model is the linear combination of the expected demand quantity and the optimal order quantity in the classical newsboy model, taking the optimal willingness rate as the weight. Through the example with different willingness functions, we demonstrated that various profits are yielded based on different willingness functions. Meanwhile, the profits from the model considering the reservation arrangement are greater than those from the classical newsboy model.
