Freight Time and Cost Optimization in Complex Logistics Networks

Figure 6

Optimal warehouse locations proposed by the k-means algorithm. (a) Freight cost decreases by increasing the number of optimized warehouses. Orange and green lines show the actual freight cost and the freight cost of transfers from the current nearest company warehouses. (b) Distribution of customers based on their distance from the nearest warehouse. (c) A network of customers (blue circles) and current (orange triangles) and optimized (red triangles) warehouse locations. Yellow circles denote geographical areas where candidate warehouses should be placed but that currently have inactive warehouses (Locations 1 and 2) or no warehouse (Location 3).
