A GRASPxELS with Depth First Search Split Procedure for the HVRP

Draw the arrows again, but this time the tail of the second arrow should be at the head of the first arrow. Then draw the arrow whose tail is the tail of the first arrow and whose

This paper is organised as follows. Necessary background on SPR modelling of CVRPSD and on belief function theory is recalled in Section 2. An extension of the recourse approach for

The proposed tabu search procedure allows all kind of infeasible moves to be done (time windows, load, routes number). We have performed some empirical tests to prove the

Average number of vehicles and distances of methods for the vehicle routing problem with time windows on 100-customer problems (CNV is the cumulative number of vehicles; CTD is

The proposed algorithm integrates several optimization methods, in- cluding heuristic approaches, a crossover operator, a local search optimization procedure and a

More precisely, at each node of the search tree, we solve a robust Basic Cyclic Scheduling Problem (BCSP), which corresponds to the CJSP without resource constraints, using a

Next, we show how the renormalization goes in symmetric systems, and finally, we discuss a procedure by means of which, given a pre-symmetric system one can produce a symmetric

Each customer i has a demand calendar d pit , which specifies the number of new units of product p that must be received in period t (i.e., by the delivery date). A
