Motivated by recent claims on the potential value of integration in warehouse management, this study evaluates the benefits arising from integrating the planning of picking and packing processes in warehouses. A set of hypotheses are proposed to examine these benefits under different conditions and an experimental study is designed to test these hypotheses. A mixed-integer linear programming model is developed to depict an integrated planning method, which is then compared against a non-integrated variation. The experimental study makes use of empirical data collected from an e-commerce warehouse. Our findings indicate that integrated planning can result in improved performance under different objectives, order quantities, order categories and workforce allocation.
