Abstract: This paper addresses the issue of input sequence, which affects the results of simulated annealing (SA) for vehicle routing problem (VRP). Also, a heuristic has been proposed which improves the result by 1.7% than the well known and frequently used input sequence. With its ability to provide solutions of good quality at low computing times, the proposed heuristic has ample scope for application as an automated scheduler when implemented at the site of a logistics-planning cell.

Keywords: heuristics; shrink wrap algorithm; simulated annealing; input sequences; vehicle routing problem; VRP; automated scheduling; logistics planning.
