Abstract (in Japanese) (See Japanese page) 
(in English) In server migration service (SMS), computers called work places (WPs) are deployed at various locations in a network, and servers for network applications (NW-Apps) may migrate between WPs to achieve better communication QoS. In this paper, we consider the electricity energy cost, an important component of the operational cost of the SMS, in addition to the financial penalty (i.e., SMS provider’s financial loss due to degradation of the communication QoS) in determining when and to which WPs servers should migrate in the SMS. We define the operational cost of the SMS as the sum of the financial penalty and electricity energy cost and consider an energy-aware server location decision problem in order to minimize the operational cost of the SMS. We formulate the problem as a mixed-integer programming model and solve the model numerically. Numerical examples show that our mixed-integer programming model optimally determines the locations of the servers and decreases the operational cost by up to 8% compared to our previous integer programming model, where the energy cost was not considered.
