- W848578419 abstract "Public and private roads, which have an insufficient bearing capacity or blocking due to thawing or heavy rains, annually contribute to a considerable profit loss in the Swedish forestry sector. One method to reduce costs related to road blocks is to restore the road network to a standard that guarantees accessibility. The problem is to prioritise in order to attain best benefits. This problem is strategic, as upgrading roads has long-term economic effects. The planning period covers a couple of decades. The road investment problem becomes a mixed integer problem or a network design problem. Some alternative mathematical formulations to this problem are presented. The suggested models have a structure where column generation is applicable. One difficulty is to determine the amount of storage that arises due to insufficient bearing capacity. An alternative way to evaluate this is presented." @default.
