In this paper, the common centralized DEA models are extended to the bi-level centralized resource allocation (CRA) models based on revenue efficiency. Based on the Karush–Kuhn–Tucker (KKT) conditions, the bi-level CRA model is reduced to a one-level mathematical program subject to complementarity constraints (MPCC). A recurrent neural network is developed for solving this one-level mathematica...

The two key resources in an IP Telephony network are the Internet Telephony Gateways (ITGs) and the IP network. These resources must be effectively managed to simultaneously provide good QoS to calls and maximize network resource utilization. This paper presents two main contributions. First, we design a call admission policy based on congestion sensitive pricing. As the load increases, this po...

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...

This paper presents a method to allocate the transmission network costs to users based on nodal pricing approach by regulating the nodal prices from the marginal point to the new point. Transmission nodal pricing based on marginal prices is not able to produce enough revenue to recover the total transmission network costs. However, according to the previous studies in this context, this met...

abstract efficiency concept has a long history in the sciences and its measurement and analysis is a vital importance for firms to achieve the best performance. hence, the aim of this paper is efficiency evaluation of mahan air compared to iata member airlines in middle east and africa. for this purpose, the indicators include available ton kilometer, revenue ton kilometer, revenue passenger ki...

in conventional dea models, decision making units (dmus) are generally assumed as a black-box while the performance of decision making sub-units (dmsus) and their importance play crucial roles in  analyzing the performance of systems which have internal processes. the present paper introduces an ideal network which have efficient processes and next purposes a new approach for evaluating importa...

The performance assessment of supply chains including sustainability dimensions of economic, environmental and social is a significant aspect for managers and decision makers. Furthermore, imprecise data are presented in many real world applications. Therefore, the current paper proposes an approach based on data envelopment analysis (DEA) to analyze the revenue efficiency of sustainable supply...

This paper analyses three quantifiable benefits of Optical Cross Connect (OXC) architectures and how these are affected by network topology and traffic characteristics. The cost-saving benefits of shared protection, the revenue increasing potential of dynamic provisioning, and the efficiency gains of network reconfiguration are analysed. All three of these benefits are available when an OXC-ena...

Abstract— We evaluate the effects of mobility and reservations on new call blocking and handoff blocking We evaluate the effects of mobility and reservations on new call blocking and handoff blocking in multirate wireless networks. The model evaluated uses Fixed Channel Assignment (FCA) with priority for handoffs over new call arrivals by reserving a number of channels for handoff calls in all ...
