The project AGIRE addresses the human resources management in warehouses which supply either sale points (B2B) or final consumers (B2C). Such warehouses are under pressure due to the no inventory policy at the sale points and to the constant growth of e-commerce sales. In terms of logistics, this translates into an increasing number of parcels to prepare and to ship to satisfy an order, which is known typically a few hours in advance.
Therefore, designing an efficient, reactive warehouse able to respond to demand variations is a significant challenge to address. A fully automated warehouse cannot be considered as a solution. Indeed, the investments required to satisfy appropriately demand peaks are too large to be considered. A more suitable approach is to combine human operators equipped with high technology devices and partially automated logistic equipments. However, to better manage human resources in such a dynamic environment, innovative decision support methods have to be designed with the objective of maximizing the welfare of workers while guaranteeing the efficiency of the whole logistics system. This is precisely the central objective of this research project.
AGIRE aims at proposing innovative human-centered decision support tools for warehouse management. This will have a tangible impact on the scientific community. Warehouse management problems have been widely studied for decades, but only few works integrate human factors when facing a dynamic demand. This project will explicitly consider these two aspects in the proposed models and algorithms. The main scientific challenges are: (1) the modeling of human and social aspects (e.g. ergonomics, pain/fatigue, congestion); (2) the integration of these human related criteria into optimization models and algorithms, (3) data analysis (e.g. demand forecast) and integration of the uncertainties into the models and solution methods, (4) integration of tactical and operational problems, and (5) solving large-sized instances: a warehouse usually contains hundreds of employees, thousands of storage locations, up to one hundred thousand products to pick each day.
AGIRE is conducted by a consortium of three complementary research teams (INOCS, SFL and SPLOTT) in computer sciences, operations research, and social sciences; and a company in the textile retail: HappyChic. Developed algorithms will be tested on real data collected in the warehouse of the brand Jules of HappyChic.
In this 4-year project, we aim at developing innovative intelligent human-centered decision support tools for warehouse management. The proposed methodology relies on an activity analysis to identify and to model the main human factors in warehouse operations. Then, different optimization problems will be addressed at operational and tactical levels (e.g. picker routing, scheduling of picking tours, storage location assignment, workload balancing). These decision levels will be integrated subsequently to ensure that decisions at the tactical level are consistent with the human factors at the operational level. In order to evaluate the obtained solutions, simulation tools will be developed, as well as experiments with feedbacks of users inside the warehouse of Jules.
