Extended Problem Instances with Sturdiness Levels and Computational Results for Joint Order Batching and Picker Routing Problem

The problem instances used in this paper are imported from Briant et al. (2020) and Valle et al. (2017), as their studies were based on a dataset from a Foodmart factory. The benchmark is well-prepared and described in detail in Valle et al. (2017), which is produced from a database of anonymized customer purchases over two years for a chain of supermarkets. We extended this dataset by randomly adding a sturdiness level to each item. We also provide our results of the new extension of the problem of Joint Order Batching and Picker Routing Problem with Sturdiness Levels
