Intelligent Warehouse Picking Improvement Model for e-Logistics Warehouse Using Single Picker Routing Problem and Wave Picking

Abstract

Abstract— The development and use of technological innovations have changed people's behavior from an industrial society to an information society. It can be seen in the increase in people's consumption patterns from trading through physical stores (offline) to trading through electronic systems, often referred to as e-commerce. Logistics services are distribution actors in the downstream line which are tasked with delivering products from the fulfillment center from e-commerce to the end customer. The uncertainty of the number of requests is the biggest challenge for logistics service players. The growth of e-commerce has also led to an increase in sales volume in e-commerce which has given rise to a new generation of warehouses that are specifically tailored to the special needs of online retailers who directly serve the demands of end-customers in the business-to-consumer (B2C) segment. Traditional warehousing systems cannot handle orders with the characteristics of many transactions but smaller sizes. In addition, warehouses that handle e-commerce are also required to have a fast process in the warehouse because shipments must be made on the same day. In this study, the author aims to perform calculations to find the optimal order picking time in the warehouse, so orders in e-commerce can be processed faster by comparing the picking process time using ordinary Single Picker Routing Problem (SPRP) and combined with the concept of wave picking using Genetic Algorithm (GA). Based on a theoretical study in this paper, the combination between SPRP and wave picking can reduce 42.28% picking time.

Improving the Quality of Warehousing Processes in the Context of the Logistics Sector

“…Moreover, there is a lack of analysis of potential models for improving the quality of warehouse processes, and little attention to wastage analysis and the introduction of automated processes. Also, there is a shortage of analysis and research on the use and benefits of in-house information systems in logistics and warehousing companies [24]. Various models are presented to help companies to improve the quality of their warehouse processes, as they usually do not know where to start improving the quality of warehouse processes.…”

A Systematic Literature Review: Design and Control of Warehouse Order Picking in Development of E-commerce Transaction

“…routing for order pickers) and strategic decision such as warehouse layout. Order batch also can be related to maximum order quantity can be stored in the capacitated warehouse [8], [9], and [10]. According to [11] the objective of the order batching strategy is to minimize the picking route distance in a manual sorting system particularly.…”
