Travel time estimation for the order picking problem in automated warehousing systems

[[abstract]]The order picking problem is an important issue in the operation of an automatic storage/retrieval system (AS/RS). An area propagation-based model designed to estimate the expected travel time required to pick an order is presented in this paper. The estimation model of the nearest neighbor (NN) heuristic was derived and Monte Carlo sampling was adopted to show the accuracy of the estimation model. The model can be applied to a carousel system with some slight modifications[[fileno]]2020401010014[[department]]工工
