考虑风险感知和项目关联的R&D网络风险传播模型

针对风险传播导致RD网络失败率过高的问题,考虑企业风险感知与企业内项目关联的特点,借鉴SIS模型构建了RD网络风险传播模型.仿真结果显示,风险传播阈值是由研发网络拓扑结构、企业风险恢复力及企业风险感知共同决定的;风险在RD网络中的传播速度和范围会随着企业风险感知的增加而降低,但会随着RD网络内项目关联的企业数量的增加而增大.研究结果表明,可以通过提高企业风险感知能力,减少项目关联的企业个数,降低项目间的关联程度来提高RD网络抗风险的鲁棒性.

Improvement of Incentive Mechanism on BitTorrent-like Peer-to-Peer File Sharing Systems

BitTorrent is a very popular Peer.to-Peer file sharing system, which adopts a set of incentive mechanisms to encourage contribution and prevent free-riding. However,we find that BitTorrent's incentive mechanism can prevent free-riding effectively in a system with a relatively low number of seeds, but may fail in producing a disincentive for free-riding in a system with a high number of seeds. The reason is that BitTorrent does not provide effective mechanisms for seeds to guard against free-riding.Therefore, we propose a seed bandwidth allocation strategy for the BitTorrent system to reduce the effect of seeds on free-riding. Our target is that a downloader which provides more service to the system will be granted a higher benefit than downloaders which provide lower service when some downioaders ask for downloading file from a seed. Finally,simulation results are given, which validate the effectiveness of the proposed strategy.
