In e-commerce fulfillment warehouses, manual item picking is a labor-intensive and tedious task. Therefore, automation of item picking can improve efficiency and save cost for e-commerce businesses. This paper presents an automated robot picking solution that meets the requirements of automating the picking of items from shelves. The hardware of the proposed system comprises a lightweight robot...

Warehousing management policy is a crucial issue in logistic management. It must be managed effectively and efficiently to reduce the production cost as well as the customer satisfaction. Synchronized zoning system is a warehousing management policy which aims to increase the warehouse utilization and customer satisfaction by reducing the customer waiting time. This policy divides a warehouse i...

A modular discrete-event simulation model for a miniload-workstation (ML-WS) order picking system has been developed using a process algebra based simulation language. The proposed model is structured systematically such that distinctions between areas and operational layers can be clearly identified. Furthermore, subsystems and decentralized controls are applied in the model architecture. We d...

This note develops analytical picker blocking models to simply and accurately assess picker blocking in parallel-aisle order picking systems when multiple picks occur at a pick point. The Markov chain-based models characterize the two bounding walking speeds for modeling picker movement: unit walk-time and instantaneous walk-time. The unit-walk time model has a state space transition matrix tha...

In the supply chain, a warehouse is an essential component for linking the chain partners. It is necessary to allocate warehouse resources efficiently and effectively to enhance the productivity and reduce the operation costs of the warehouse. Therefore, warehouse management systems (WMSs) have been developed for handling warehouse resources and monitoring warehouse operations. However, it is d...

A software tool is developed to simulate a person aboard automated storage/retrieval vehicle in an order pick system. The program allows the calculation of the travel time of the storage/retrieval vehicle depending on different item and order patterns, storage assignment strategies, batching methods, and routing algorithms. It consists of a set of modules, which can be extended to model a wider...

This paper studied a new combined automatic warehouse system, which can not only realize storage and sorting process, but also process the replenishment request according to inventory demand. In this there are two areas, one for pallets other totes. Pallet area picking, tote handle cases picking. addition, system automatically initiates from pallet area, when is lower than safety stock. uses ch...
