Garbage is one of the environmental problems. The process transporting garbage sometimes occurs delays such as congestion and engine failure. Robust optimization model called a robust counterpart open capacitated vehicle routing problem (RCOCVRP) with time windows was formulated to get over this delays. This has limitation capacity an uncertainty waste volume travel time. RCOCVRP solved by heur...

An electric vehicle routing problem (EVRP) with time windows is carried out using a hybrid algorithm. Through the modeling of problem, not only energy consumptions and charging durations EDVs, but also conventional flow formulations soft window constraints are taken into account. A solution method proposed to solve EVRP. The combines genetic algorithm simulated annealing complement each other. ...

This paper proposes a tabu search algorithm for the two-echelon vehicle routing problem with time windows and simultaneous pickup delivery (2E-VRPTWSPD), which is new variant of problem. 2E-VRPTWSPD involves three stages routing: (1) first-echelon vehicles start from depot to deliver cargoes satellites; (2) second-echelon satellites serve customers within in simultaneously manner finally return...
