In many order picking and sorting systems conveyors are used to transport products through the system and to merge multiple flows of products into one single flow. In practice, conveyor merges are potential points of congestion, and consequently can lead to a reduced throughput. In this paper, we study merges in a zone picking system. The performance of a zone picking system is, for a large par...

We consider a multi-product serial two echelon inventory system with stochastic demand. Inventories at the downstream location are replenished periodically using an automatic ordering system. Under vendor managed inventory strategies the upstream stage is allowed to adapt these orders in order to benefit from economies of scale. We propose three different VMI strategies, aiming to reduce the or...

At present, the fruit picking in most countries still largely relies on manual operation. Manual fruit picking can protect the fruits from damage during the operation process. However, it is time-consuming and labor-intensive, and poses a potential safety risk to the workers while working at heights not reachable. Therefore, a variety of fruit picking machines and platforms have been developed ...

Up to 50 per cent of all warehouse operations costs can be attributed to order picking [1]. It is an aspect critical to each supply chain and the planning and control of warehouse processes. According to experience from logistics environments, a reduction of picking times is an integral part of the delivery lead-time and may result in an improvement of the customer service provided by a warehou...

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...

In the era of e-commerce, the logistic distribution center is put in the center role of order picking for the sake of meeting the needs of different customer orders, hence, improving the automation and work capacity of distribution center becomes research priority in the fields of logistics and warehousing. The objective of this article is to solve the shortcomings of currently traditional dist...

Order picking is a crucial operation in the storage industry, with significant impact on efficiency and cost. Responding quickly to customer demands shortening time given random nature of order arrival times quantities. This paper presents study order-picking process distribution center, employing “parts-to-picker” system, based dynamic batching task optimization. Firstly, arriving orders uncer...

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...

Abstract Challenges in strawberry picking made selective harvesting robotic technology very demanding. However, the of strawberries is a complicated task forming few scientific research questions. Most available solutions only deal with specific scenario, for example, single variety fruit isolation. Nonetheless, most economically viable (e.g., high‐yielding and/or disease‐resistant) varieties a...
