Nekbone is a proxy application of Nek5000, a scalable Computational Fluid Dynamics (CFD) code used for modelling incompressible flows. The Nekbone mini-application is used by several international co-design centers to explore new concepts in computer science and to evaluate their performance. We present the design and implementation of a new communication kernel in the Nekbone mini-application with...
Bus is the most popular public transportation mode due to high loading capacity and low infrastructure requirement. Because operation time is long, bus transit system is required to run in a green manner. In this paper a transit fleet replacement model is developed to make vehicle purchase and retirement decisions under environmental and technological constraints. The overall objective is to find...
Planning and Scheduling is a decision-making process of allocating limited resources to tasks over time with the goal of optimizing a certain objective. Most of them do not have a polynomial time algorithm and are NP-hard problems. The requirements from a real world application might be that several goals need to be achieved simultaneously, which makes problems even much harder to solve. This paper...
