Abstract. This paper considers the planning of the collection of fresh milk from local farms with a ﬂeet of refrigerated vehicles. The problem is formulated as a version of the Periodic Vehicle Routing Problem with Time Windows. The objective function is oriented to the quality of ser-vice by minimizing the service times to the customers within their time windows. We developed a hybrid metaheuristic that combines GRASP and VNS to ﬁnd solutions. In order to help the hybrid GRASP-VNS ﬁnd high-quality and feasible solutions, we consider infeasible solutions during the search using diﬀerent penalty functions.
