Corrigendum and a complement 'A simple heuristic for vehicle routing - A variant of Clarke and Wright's saving method' [Int. J. Prod. Econ. 157 (2014) 74-79]

摘要

A simple heuristic for vehicle routing - A variant of Clarke and Wright's saving method (International journal of Production Economics, 157 (2014), 74-79) contains a mistake that must be corrected. But the mistake also allows for a possible improvement of the search procedure which is demonstrated. We emphasise that the chosen sequence of the distribution, clockwise or anti-clockwise, can highly influence the vehicles' fuel consumptions.
