“…Hong et al (2012) report limited picker blocking when their proposed batching algorithm is used to generate batches, but they do not explain why their algorithm would experience relatively little picker blocking.…”

“…Parikh and Meller (2010)'s comparison of high and low pick time variations does not definitively show that a high variation over the same work load results in more picker blocking. Neither Ruben and Jacobs (1999) nor Hong et al (2012) identify the batch formations which increase the variation of pick time.…”

“…In proposing a batching algorithm which minimizes travel distance, Hong et al (2012) report a small increase in retrieval time due to picker blocking. Their resulting order-picking operations are relatively robust to picker blocking.…”

“…In general, distancebased approaches with their relatively simple implementation (Ruben and Jacobs, 1999) are preferred for aggregating orders whose items are closely located within a storage space. The literature (Ruben and Jacobs, 1999;De Koster et al, 1999;Gademann and Van de Velde, 2005;Gademann et al, 2001;Hong et al, 2012) describes various algorithms that identify orders to be picked together for the purpose of reducing travel distances and number of trips.…”

This paper analyses the best batch formations for order picking throughput in narrow-aisle order picking systems. Our analytical comparison finds that a high pick density variation leads to a heavy picker blocking. Simulation experiments show that a distance-based batching algorithm reduces picker blocking by decreasing the number of aisles visited and stabilizing the variation in number of picks per aisle by packing orders tightly, and that the solution quality and mechanism for determining the batch size dictated by the sorting strategy causes varying amounts of blocking. We conclude that combining a distance-based batching method with an appropriate batch sizing strategy will reduce picker blocking and shorten travel in narrow-aisle picking systems.
