Small-Size Problem Instances for 3L-CVRPTW
To examine the performance of developed models, which are exact solution approaches, and the hybrid method, we created small-size instances from Moura and Oliveira (2009). These instances consist of three classes and eight groups. Groups (G1, G2, G3) are defined from shorter planning horizons to longer, "planning horizon" indicates an average service duration of customers. Classes (1-8) are defined from fewer customers to more customers. Vehicle capacities (dimensions) vary according to the number of customers. Twenty-four instances are created with 5 to 25 customers and 15 to 115 boxes.
