Improving last-mile transport planning by nudging customer delivery windows based on a dynamic spatial customer grouping: Simulating nudging of customer delivery windows at order creation

With routing algorithms approaching optimization limits, other approaches are required to further improve the last-mile delivery of goods. In this paper, an analysis is made of the effectiveness of nudging customer delivery windows at order creation dependent on a dynamic spatial grouping to improve last-mile routing performance. During this...

A grouping method for optimization of steel skeletal structures by applying a combinatorial search algorithm based on a fully stressed design

In the design of steel structures, optimization methods can find minimum weight solutions. However, the solutions tend to have a high diversity of profiles, thereby raising costs. Grouping methods provide a solution by limiting the number of unique profiles, while still providing an optimal solution. This study proposes a new grouping method and...

Buildable Design in Optimisation of Steel Skeletal Structures: A Comparison of Existing and New Methods for Finding the Best Solution with Low Diversity

In the design of steel structures, optimisation methods promise cheap, light and sustainable structures. However, the resulting designs tend to have a high diversity of profiles, making them unbuildable. Furthermore, the optimisation problem is mathematically complex, leading to a long and potentially unsolvable optimisation process. Grouping...
