Besides being a hard combinatorial problem, the VRP is also a spatial problem. Hence, effective decision making in this field strongly requires the integration of GIS and optimization systems (GIS-O). This article integrates GIS and optimization tools for solving the vehicle routing problem with loading and distance requirements (DCVRP). A general outline of the multi-step integration is pointe...

Resonance and wave-propagation problems are known to be highly sensitive towards parameter variations. This paper discusses topology optimization formulations for creating designs that perform robustly under spatial variations for acoustic cavity problems. For several structural problems, robust topology optimization methods have already proven their worth. However, it is shown that direct appl...

The readers may first see the numerical results to find what is possible by optimization. In the appendix, overview of structural optimization in architectural design is presented, and effectiveness of optimization is demonstrated by small examples. Each chapter is a part of a published paper, or translation from a Japanese article. So there might be some difficulties for understanding the deta...

Abstract Strategic placement of urban agriculture such as community gardens can expand alternate food supply, support physical activity, and promote social interactions. While health benefits are critical priorities when planning new locations, no widely accepted site selection methods have been established. We developed a spatial optimization model to identify locations in the City Indianapoli...
