Abstract
Snow removal is important for the snowy region in winter, in order to provide stable road network service. Most of the private contractors who are in charge of snow removal are small and medium enterprises located in the region. They are reducing their employees and machinery due to decreasing budget for construction project in recent years, which has weakened the ability to respond to snow removal.
Therefore, an efficient snow removal operation with limited resources is required. Locating snowplows and their working area have often been set by the experience of local engineers, which cannot necessarily make the snow removal operations efficient enough. Therefore, in the future of snow removal operations, it is necessary to aim reduction of snowplows and the cost by making snow removal operation plan based on certain rules. In this paper, we set the management target level that is based on the organized data about the amount of snowfall and the importance of the road, and we show a method for determining how to locate snowplows to achieve the target level.
