Abstract: Techniques are disclosed for generating a delivery schedule for distributing commodity products to a group of customers grouped by clusters. For example, a distributor/producer of refined gasses distributed via cylinders may create a proposed delivery schedule limiting the days at which product is delivered to different customers. A delivery planning application may include a clustering module a set of input data to generate a set of clusters representing groups of customers, e.g., using a Greedy Algorithm optimized using a Tabu search. Once the clusters are generated, a planning module may be used to affect trucks (or other delivery vehicles) to clusters. A truck affected to a given cluster by the delivery planning application is then scheduled to deliver cylinders to that cluster. The delivery schedule may provide a reusable two-week plan for servicing a group of customers in a supply chain network.
