The review focused on keywords related to logistics service providers, outsourcing, and decision. Additionally, the paper presents and analyzes keyword maps related to logistics outsourcing research and maps identifying countries involved in logistics outsourcing research. The goal is to trace the evolution of research on logistics outsourcing decisions and provide insights into emerging areas for future exploration.
