We report on recent progress in the iterative process of exploring, evaluating and refining Augmented Reality based presentation schemes for logistic applications. In this context we have evaluated different ways of presenting working instructions with HMD-based Augmented Reality systems to support the order picking process. Order picking means that workers have to pick items out of numbered bo...

The objective of the paper is to investigate walking stability of picking wheel robot in the fields of medium speed and high load complex operating environment. Firsly, we analyze the influence on walking control for simplified dynamic model of picking robot and its remaining (instabilities), guarantee the stability and convergence of simplified system for tracking errors using the Lyapunov the...

Distribution centers are one of the most important components in a supply chain. In the context of a new global economy in which filling orders within a 24-hour period is the industry standard, product locating, replenishing and picking activities must be managed efficiently. This article proposes and analyzes different product location and replenishment strategies for a distribution center tha...

Congestion is a problem in order-picking-systems. We developed CTMC models to represent picker blocking in cases including pickers with different exponentially distributed picking times and k pickers, for narrow and wide aisle systems. The focus was not to produce an all-inclusive model, but to generate models that give designers insight of the system, allowing them to reduce the number of vari...

The present work addresses an operational inefficiency problem at a semiconductor equipment manufacturing warehouse, Varian Semiconductors Associates and Equipment (VSEA). This problem is important because if unresolved, the warehouse is unable to meet the part delivery time target of 24 hours during the busy period. The downstream effects of the late part delivery are delayed production schedu...

This article examines the effect of three process decisions (picking, storage, and routing) on order picker travel, which is a major cost component of order fulfillment. The authors use a simulation model based on the operations of a distribution center that is currently picking one order at a time, storing product in a haphazard or random fashion, and using a simplistic procedure for routing p...

Many operations are characterized by a trade-off between speed and quality. This calls for an exploration of effective strategies to balance the two metrics. study investigates separate joint effect quantity quality feedback on both performance metrics in order picking. We collected data from real-effort experiments with total 212 participants, who conducted picking task experimental warehouse....

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...
