This article presents a practical tool for optimally schedulingwinegrape harvesting operations taking into account both operational costs and grape quality. We solve a mixed-integer linear programming model to support harvestscheduling, labor allocation, and routing decisions. A quality loss function is used to represent wine quality reduction at each vineyard block due to premature or deferred harvest with respect to an optimal date. We present computational results which show that the proposed tool could be used to support grapeharvest planning in a large vineyard, at both a tactical and operational level.
