A Comprehensive Model for Calculating the LPI Index of Key Transport Corridors in Serbia

The Logistics Performance Index (LPI) represents a tool developed by the World Bank that is used to measure the efficiency and effectiveness of a country's logistics sector, and comprises of six components.This indicator is used to compare the logistics performance of different countries, identify challenges in global supply chains, and help policymakers improve their logistics infrastructure and service quality.Given the importance of this indicator, every country aims to achieve a higher LPI score and, consequently, a more favorable ranking.The objective of this paper is to propose a new methodology for calculating the LPI score for transport routes.To validate the proposed methodology, the study analyzes seven cases involving import and export flows from Serbia.Based on the results, the analysis identifies which transport routes achieve the highest scores and which require specific preventive and corrective actions to improve their performance.
