http://emaj.pitt.edu/ojs/emaj/article/view/39/195 WebIntroduction. In 1964 Clarke & Wright published an algorithm for the solution of that kind of vehicle routing problem, which is often called the classical vehicle routing problem. This algorithm is based on a so-called savings concept. This note briefly describes the algorithm and demonstrates its use by an example. 2.

WebThe routing policy used is the return heuristic, meaning that order pickers only enter storage-aisles containing picks and they enter and leave the storage-aisle from the same end. WebBut, remember, a heuristic only gives an approximate solution. For this particular heuristic, the solution will be, on average, about 25% longer than the shortest possible path. There are even times where the nearest neighbor heuristic will give the worst route.
