The fleet for surface transit in urban areas - number of buses and vehicle size - is usually determined by the characteristics of demand during the peak period, adjusting frequencies for other periods where those characteristics ...

In structural design optimization, engineers and designers aim to obtain more efficient designs with regards to weight, stiffness and frequency measures, for a given set of design variables. These design variables can be ...

In this paper, we propose a simple but efficient heuristic that combines construction and improvement heuristic ideas to solve multi-level lot-sizing problems. A relax-and-fix heuristic is firstly used to build an initial ...
