Optimal Storage Layout And Order Picking For Warehousing
نویسندگان
چکیده
In this paper, issues of storage layout and order picking operations problems for warehousing are addressed using optimization techniques. The aim of this study is to develop a dynamic planning system applied for storage layout and order-picking operations problems. The planning system considers dynamic nature of customer order demand, configuration of picking area, and interactive human-machine interface. Heuristic-based optimization technique is utilized to design the planning system. To analyze the dynamic nature of customer order demand, similarity measures among types of items are defined using the entry-order-quantity rule. Based on the characteristics of customer order demand and the configuration of picking area, a zero-one quadratic generalized assignment model is developed. A heuristic procedure is devised to find near-optimal solutions to this problem and coded using Borland C++ computer language. An industrial size application is performed to demonstrate this approach. Results indicate that the developed planning system can be promising for dealing with storage layout and order picking operations problems for warehousing.

Designing the Layout Structure of Manual Order Picking Areas in Warehouses
Order picking is the warehousing process by which products are retrieved from their storage locations in response to customers’ orders. Its efficiency can be influenced through the layout of the area and the operating policies. We present a model that minimizes travel distances in the picking area by identifying an appropriate layout structure consisting of one or more blocks of parallel aisles...
متن کاملA model for warehouse layout
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...

The power of warehousing system to rapidly respond to customer demands participates an important function in the success of supply chain. Before picking the customer orders, effectively consolidating orders into batches can significantly speed the product movement within a warehouse. There is considerable product movement within a warehouse; the warehousing costs can be reduced by even a small ...
