The aim of this research was to measure the relative efficiency of forest management plans in north of Iran. In order to fulfill the research, data of 12 forest management plans were collected from the financial balance sheets of Shafaroud Forest Company during a ten years period. First of all, basic Data Envelopment Analysis (DEA) models (BCC and CCR) were used to determine the efficiency. The...

the revenue management concept and techniques are applied to model the coordination of supply chain elements. the fundamental premise of this approach is synchronization of a group of business entities consist-ing of a manufacturer and multiple suppliers to achieve an optimal supply chain capacity plans. the output of the supply chain can be various products and thus it is measured in terms of ...

Motivated by emerging applications in workforce management, we consider a class of revenue management problems in systems with reusable resources. The corresponding applications are modeled using the well-known loss network systems (sometime also called the stochastic knapsack model). We use an extremely simple linear program (LP) that provides an upper bound on the best achievable expected lon...

While inventoryand revenue-management problems can be represented as Markov decision process (MDP) models, in some cases the well-known dynamic-programming curse-ofdimensionality makes it computationally prohibitive to solve them exactly. An alternative solution approach, called here the control-algorithm approach, is to employ a math program (MP) to approximately represent the MDP and use its ...

Quality of service of e-commerce sites has been usually managed by the allocation of resources such as processors, disks, and network bandwidth, and by tracking conventional performance metrics such as response time, throughput, and availability. However, the metrics that are of utmost importance to the management and shareholders of a Web store are revenue and profit. Thus, resource management...

One of the main priorities of companies involved in supply chains is improving the quality of their products. However, as in other parts of supply chain management, decentralized decision-making in supply quality management is prevalent, which causes inefficiencies such as the well-known double marginalization phenomenon. Coordinating schemes, such as the revenue sharing contract, can contribut...

Applying peer-to-peer communications in cellular networks to improve performance has been an active research area in recent years. Cooperation among nodes is an important prerequisite for the success of the multi-hop cellular networks. Cost savings and service availability are the primary concerns that the network provider adopts multi-hop cellular networking technology. In this paper, we prese...
