of easy virtue
6.Virtue enterprise has drawn a worldwide attention as electronic business developed rapidly.How to evaluate the performance of supplier in virtue enterprise is still not well addressed.Lots of theories have been presented.However,most of them aye lack of a reliable model.One of the main model aiming to solve this problem is supplier performance index (SPI),and Q-adjustment SPI.However,SPI is presented for a static enterprise and especially for a long term relationship with the supplier,which make it not fit for the virtue enterprise.Considerate its easy using and economic cost makes it much more attractive than any other ways for enterprise,we build a new model based on the SPI model to make it suitable for the virtue enterprise using without hamper its original advantages.
8.This paper reviews a traffic management algorithmvirtue clock algorithm used in ATM (Asynchronous Transfer Mode) and compares some methods based on the algorithm. At the same time, not only the virtue clock algorithm applicated in BISLN(Broadband Integrated Service Local Network) is provided and a easy realizable queue management method is designed, but also a prototype of BISLN is realized.
