A Survey of the Literature on Order-Picking Systems by Combining Planning Problems

Featured Application:& nbsp;In this paper, we review the combination of cost, equipment, warehousing, allocation, routing, batching, sequencing, and tardiness problems, and examine the scientific literature that combines order picking planning problems. Companies have been trying continuously to reduce their logistics costs in the current competitive markets. Warehouses are important components of the logistics systems and they must be managed effectively and efficiently to reduce the production cost as well as maintain customer satisfaction. Order-picking is the core of warehouse operations and an order-picking system (OPS) is essential to meet customer needs and orders. Failure to perform the OPS process properly results in high costs and customer dissatisfaction. This research aims to investigate the state of the art in the adoption of OPS and provide a broad systemic analysis on main operating strategies such as simultaneous consideration of order assignment, batching, sequencing, tardiness, and routing need. This study reviews 92 articles, classifies combinations of tactical and operational OPS problems, and provides guidelines on how warehouse managers can benefit from combining planning problems, in order to design efficient OPS and improve customer service. Combining multiple order-picking planning problems results in substantial efficiency benefits, which are required to face new market developments.

Automated summary

The study examines the combination of multiple order-picking planning problems, aiming to reduce logistics costs and improve customer satisfaction in competitive markets. Effective warehouse management and implementation of order-picking systems are essential to enhance production efficiency and maintain customer satisfaction.
