Abstract With the growing number of Web services on the internet, there is a challenge to
select the best Web service which can offer more quality-of-service (QoS) values at the
lowest price. Another challenge is the uncertainty of QoS values over time due to the
unpredictable nature of the internet. In this paper, we modify the interval data envelopment
analysis (DEA) models [Wang, Greatbanks and Yang (2005)] for QoS-aware Web service
selection considering the uncertainty of QoS attributes in the presence of desirable and
undesirable factors. We conduct a set of experiments using a synthesized dataset… More >
