Instances for the two-echelon location routing problem with two-dimensional loading constraints
Datasets used in the paper "The impact of loading restrictions on the two-echelon location routing problem". Each folder, 2E-LRP and 2E-LRP2l, contains the set of instances, best obtained solutions, and detailed results. Formats of input and output are described on files "README_instanceFormat" (located inside each instance folder) and "README_format" (located inside best solutions folder). The excel file "Result" provides details of the instances: best and average solution values as well as computational time and coefficients of variation.
