A number of studies have considered the evaluation of efficiency in higher education institutions. In this paper we focus on the issue of revenue efficiency, in particular ascertaining the extent to which, given output prices, producers choose the revenue maximising vector of outputs. Following Johnson and Ruggiero (2011), we then relax the price taking assumption to consider the case in which ...

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...

Abstract This paper presents an automated approach for providing ranked lists of outliers in observed demand to support analysts network revenue management. Such management, e.g. railway itineraries, needs accurate forecasts. However, across or parts a complicate forecasting, and the structure makes such hard detect. We propose two-step combining clustering with functional outlier detection ide...

This paper analyses the problem of sub-national revenue mobilization in Peru and proposes several policy reforms to improve collection performance while maintaining a sound revenue structure. We analyze the current revenues of regional and municipal governments and identify the main priorities of reform. Among the most important problems are the acute inequalities and inefficiencies associated ...

Wireless networks are evolving to include Internet access to interactive multimedia and video conferencing as well as traditional services such as voice, email and web access. These new applications can demand large amounts of network resources, such as bandwidth, to achieve the highest levels of quality (e.g. picture quality). In conjunction with this trend, charging and resource allocation sy...

Combinatorial Auctions (CAs) are promising to increase social welfare by enabling bidders to express their valuation on any combination of items. A major issue of many CAs is the requirement to optimally solve the NP-hard Combinatorial Allocation Problem. To release a centralized auctioneer from that computational burden he can shift it to the bidders. One of the few discussed decentralized auc...

In this paper, a new method for developing a lower bound on exact completion time distribution function of stochastic PERT networks is provided that is based on simplifying the structure of this type of network. The designed mechanism simplifies network structure by arc duplication so that network distribution function can be calculated only with convolution and multiplication. The selection of...
