  • Publication number: 20130203427
    Abstract: A method for selecting one or more resources for use from among a set of resources comprises obtaining (201) a first sub-set of the resources. The resources belonging to the first sub-set are the ones which have, according to occupancy information gathered over a long period of time, highest probabilities of matching requirements related to estimated usage time and/or needed capacity. The method further comprises selecting (202) a second sub-set from among the first sub-set of the resources on the basis of second occupancy information gathered over a short period of time. The resources belonging to the second sub-set are the ones from among the first sub-set which, according to the second information, have highest probabilities of matching requirements related to estimated usage time and/or needed capacity. The subsequent use of the long and short term occupancy information increases the probability of optimal selection.
