Snow removal and disposal are expensive winter activities that affect the quality of life and the environment in cities throughout the world. To facilitate traffic flow in urban regions that receive heavy snowfall, snow is first plowed from streets and sidewalks and then hauled to disposal sites. A city is typically divided into many sectors that are cleared of snow concurrently. This paper briefly describes urban snow removal and disposal operations and analyzes the snow disposal assignment problem for assigning snow removal sectors to snow disposal sites. The snow disposal assignment problem is formulated as a multi-resource generalized assignment problem. A two phase heuristic solution procedure is developed, and solutions and sensitivity analyses are presented using data for the City of Montreal.
