DEA as an effective approach to evaluate the relative efficiency of DMUs, recently applied in many production and operation systems. This paper proposed a new k-stage DEA based MOLP model for target setting in the serial network structures, considering undesirable outputs. Since the proposed model takes the size of DMUs into account, the new idea ensures the possibility of the results. The resu...

New technologies such as IEEE 802.16 (Wi-MAX) [2] and IEEE 802.11e (Wi-Fi with QoS) [1] enable differentiated services. In this study we explore the potential for increasing the revenue of Internet service providers with differentiated services. For concreteness, we focus on two generic services that we call “voice” and “data.” However, the analysis applies to services that have different requi...

W e consider a supply chain with a supplier that sells to a retailer under a revenue-sharing arrangement. Demand is uncertain and unobservable to the supplier. We assume that the retailer is rational, that is, the retailer behaves opportunistically and underreports sales revenues to the supplier whenever such underreporting is profitable. Assuming the supplier has the ability to audit the retai...

The emergence of budget airlines, the advent of new sales channels, the disappearance of traditional fare-class fences, and other on-going changes in the airline industry pose serious challenges to traditional revenue management models, which make some rigid and unrealistic assumptions. One of these is that passengers who do not get the fare they want book and travel on other airlines or do not...

Abstract We are concerned with computing bid prices in network revenue management using approximate linear programming. It is well-known that affine value function approximations yield which not sensitive to remaining capacity. The analytic reduction compact programs allows the efficient computation of such prices. On other hand, capacity-dependent can be obtained separable piecewise approximat...

Non-uniform distribution of customers in a region and variation of their maximum willingness to pay at distinct areas make regional pricing a practical method to maximize the profit of the distribution system. By subtracting the classic objective function, which minimizes operational costs from revenue function, profit maximization is aimed. A distribution network is designed by determining the...

A supply chain is a set of suppliers, manufactures and distributors, which are linked together. The first chain is a supplier and the last one is customers. What is the most important in supply chain are highquality products by the least cost and the most benefit. In this regard, each input and output and intermediate have unit price and unit cost information. The cost-minimization and the prof...
