<p>PROBLEM TO BE SOLVED: To efficiently derive a planned stop execution date of a virtual hosting service.SOLUTION: A planned stop optimum execution date derivation system converts a use rate of each day kind daytime/knight of each system stored in a use mode table 71 and a use rate of each day kind and daytime/knight of each of a plurality of servers and resources stored in an operation situation table 72 by use of the use mode table 71 storing the use rate of a system mode of each system configured by a vertical server and each day kind daytime/knight and the operation situation table 72 storing the use rate of each day kind and daytime/knight of each of the plurality of servers and resources into the number of points by use of a point conversion parameter 81, and performs weighting such that points of the virtual server or the system not adequate to a planned power outage become large according to the converted points, so that the planned stop optimum execution date derivation system efficiently derives a planned stop execution date on the basis of information such as a use mode of a user or a stop restriction condition.</p> |
