Distribution of hobbing machine spare parts is a key factor to improve the efficiency of service-oriented spare part … allocation. In order to minimize the distribution route, the distribution model of hobbing machine spare parts with time limits … was put forward. The modified savings algorithm was adopted to solve the model. To improve the loading rate of classic …

develop a Branch-Price-and-Cut algorithm (BPC) to solve the problem. The pricing problem results in solving an Elementary … dynamic programming algorithm which incorporates ng-path relaxation and a bidirectional labelling search. Pricing heuristics …

splitting, splitting customer deliveries can be done any number of times. We propose a hybrid algorithm consisting of a local … search algorithm for routing and a genetic algorithm and several construction heuristics for packing. Numerical experiments …
