A Model for an Order-Picking Problem with a One-Directional Conveyor and Buffer

Abstract

Customers seek items at low prices, excellent quality, and customization in today’s market. Additionally, the need for quick product delivery is rising because of the expansion of e-commerce. Order picking is an essential element of order fulfillment and is regarded as one of the most costly and time-consuming tasks for warehouses. The study aims to create a model for the ordering in logistics that involves the group of racks with assigned one-way conveyor and buffers. The focus of this study is on improving the customer order completion time because of appropriate tasks assigned to pickers. The simulation was performed using the CPLEX solver. The findings highlight the need for picking operations to manage time resources, as well as the importance of sustainable work of order pickers in logistic centers in fostering sustainable performance outcomes.

A Novel Parts-to-Picker System with Buffer Racks and Access Racks in Flexible Warehousing Systems

“…For example, in the Min-3 Model, there are 80 buffer units, and the capacity can reach 2240 when the warehouse is 860 square meters, and the picking efficiency can reach 2044 boxes per hour. More importantly, this sustainable improvement for existing warehouses realizes the efficient utilization of spatial resources [54,55] and provides important support for the construction of green supply chains.…”
