Highlights For multi-dock-door cases, expected distance for Layout C increases dramatically. Layout B always performs better than Layouts A and C for dual-command travel. Layout A is wider and shorter than Layouts B and C for dual-command travel. Increasing number of dock doors increases optimal shape factor for Layouts A and B. Increasing number of dock doors decreases optimal shape factor for Layout C.
Abstract This study develops discrete formulations of expected distance traveled in a unit-load warehouse with a middle-cross-aisle. Defining optimal shape factor as the width-to-depth ratio of a rectangle-shaped warehouse minimizing expected distance traveled, our results reveal the number of dock doors and the number of storage/retrieval locations significantly affect the optimal shape factor regardless of the orientation of storage/retrieval locations. Providing computational results based on realistic parameter values, configurations are compared based on the number of storage/retrieval locations. Based on the results, recommendations are provided regarding conditions in which each layout configuration minimizes expected distance traveled.
