Heuristics for Rich Profitable Tour Problems

We present a Rich variant of the Profitable Tour Problem (RPTP) arising when customer requests involve several products and multi-compartment vehicles are used. The RPTP addressed may be considered as a variant of the capacitated profitable tour problem with time windows and incompatibility constraints. We propose a Variable Neighborhood Search Algorithm embedded with an Adaptive Large Neighborhood Search for the RPTP. This method includes a perturbation phase based on the Ruin and Recreate paradigm. The efficiency of the proposed algorithm is assessed by solving the instances of the Orienteering Problem with Time Windows.
