Abstract
We describe two optimization methods for vehicle routing problems with time windows. These are a K-Tree relaxation with time windows added a s side constraints and a Lagrangian decomposition in which variable sp litting is used to divide the problem into two subproblems-a semi-assi gnment problem and a series of shortest path problems with time window s and capacity constraints. We present optimal solutions to problems w ith up to 100 customers.
