Abstract This study intends to propose a novel approach based on fuzzy synthetic evaluation in order to realize power enterprise supply chain performance evaluation. Through the characteristic analysis of power enterprise supply chain, a 2-dimensions mesh framework for power enterprise supply chain performance evaluation is put forward, and the indexes of power enterprise supply chain performan...

Directional antennas provide numerous benefits, such as higher gains, increased transmission range, and lower interferences. In this paper, we propose a reliable broadcast protocol for directional antenna referred to as beam table-based reliable broadcast for directional antennas (BTRB). The BTRB employs (1) ACK-based scheme to provide full reliability; (2) spatio-temporal ACK combination to re...

We study distributed choice of retransmission probabilities in slotted Aloha under power di erentiation. We consider random transmission powers and further study the role of priorities (through power control) given either to new arriving packets or to backlogged ones. We study both the cooperative team problem in which a common objective is jointly optimized as well as the noncooperative game p...

Data Envelopment Analysis (DEA) has been long employed as a popular methodology to evaluate the performance of various production activities with multiple inputs and outputs. However, an important issue is that the production process in the real world inevitably generates undesirable outputs (like wastes and pollutants) along with desirable outputs. Therefore, the undesirable outputs should be ...

Nowadays cloud infrastructures allow storing and processing increasing amounts of scientific data. However, most of the existing large scale data management frameworks are based on the assumption that users deploy their data-intensive applications in single data center, few of them focus on the inter data centers data flows. Managing data across geographically distributed data centers is not tr...
