<p><P>PROBLEM TO BE SOLVED: To execute a plurality of data distribution in the optimal sequence under the constraint of a distribution permission date, a distribution end date, and a distribution execution inhibition time zone. <P>SOLUTION: When a data transfer speed is estimated about each distribution job, and an execution time is estimated on the basis of the speed, a distribution end prediction date and time is estimated on the basis of the distribution end prediction date and time of the distribution job whose execution has been predetermined and the estimated execution time, and a difference time between the distribution end date and the estimated distribution end prediction date and time is calculated. Then, the distribution job whose difference time is the minimum is selected, and determined as the distribution job to be executed the next. In performing this processing, the distribution job whose distribution starts posterior to the distribution permission date is determined as the object of selection, and the selection of the distribution job is performed. Also, the distribution job which does not exist in the distribution execution inhibition time zone in starting distribution, and which does not enter the distribution execution inhibition time zone until the distribution end prediction date and time is regarded as the object of selection, and the selection of the distribution job is selected. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
