With the continuous development of e-business, e-business distribution center operating mode is gradually changing. Small batch and more frequency is the characteristics of the e-business. The new characteristics gives birth to new distribution center picking mode. This paper analyzes disadvantaged of the business mode of the current e-business distribution center, put forward a new type of e-b...

This paper describes an approach to determine a layout for the order picking area in warehouses, such that the average travel distance for the order pickers is minimized. We give analytical formulas by which the average length of an order picking route can be calculated for two different routing policies. The optimal layout can be determined by using such formula as an objective function in a n...

We propose a simulated annealing algorithm specifically tailored to optimise total retrieval times in a multi-level warehouse under complex pre-batched picking constraints. Experiments on real data from a picker-to-parts order picking process in the warehouse of a European manufacturer show that optimal storage assignments do not necessarily display features presumed in heuristics, such as clus...

Mouse picking is the most commonly used intuitive operation to interact with 3D scenes in a variety of 3D graphics applications. High performance for such operation is necessary in order to provide users with fast responses. This paper proposes a fast and reliable mouse picking algorithm using graphics hardware for 3D triangular scenes. Our approach uses a multi-layer rendering algorithm to per...

Using data mining techniques, this study attempts to explore how a proper layout zoning following class-based storage enhances order picking efficiency over randomized storage. Association web statistics and association rule mining examines the relative intensity levels among various product categories. These findings serve as the layout for zoning of the storage area of α company, a pharmaceut...

Modern fulfilment centers need to process a far higher volume of smaller orders with increasing picking costs. These picking costs can be up to 60% of total warehousing costs. Order picking is a process of gathering requested stock keeping units one order at a time, while picking operations involve a lot of large and medium-sized companies which belong to many industrial and service sectors. A ...

Order picking deals with the retrieval of articles from their storage locations in order to satisfy customer requests. A major issue in manual order picking systems concerns of the transformation and consolidation of customer orders into picking orders (order batching). In practice, customer orders have to be completed by certain due dates in order to avoid delay in the shipment to customers or...

Order picking is defined as the process of clustering and scheduling orders, assigning stock on location to order lines, releasing orders to the floor, picking the articles from storage locations and the disposal of the picked articles (De Koster et al. 2007). Picking is the most labourintensive operation in warehouses with manual systems and a very capital-intensive operation in warehouses wit...
