Liquified petroleum gas (LPG) plays a vital role inthe energy sector throughout the world and in Bangladesh. However, the Post-COVID-19 era and the ongoing Russia-Ukraine war caused energy supply disruption globally. The LPG supply chain is also exposed to various risk factors. Therefore, this study aims to identify the major risk factors and prioritize them to improve the resilience of the LPG supply chain. In the study, Multi-criteria decision-making (MCDM) techniques including Analytic Hierarchy Process (AHP),Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS), and Preference Ranking Organization Method for Enrichment Evaluation (PROMETHEE) methods were used. AHP-TOPSIS and AHP-PROMETHEE, these two integrated combinations were used to verify the robustness of the study result. The study reviewed the literature to find the risk prioritizing criteria and the risk factors, and also take input from the experts. This study selected six criteria and 17 risk factors. Using the experts' opinion, the AHP found "Impact on business" and "Probability of occurrence" are the two most weighted criteria for LPG supply chain risk prioritization. "Price fluctuations due to changes in demand or supply, geopolitical events, or regulatory changes", "Cybersecurity breaches including hacking, malware, and other types of cyber-attacks", and "Economic or financial crises leading to changes in demand and supply" have been identified as the topmost three risks in both AHP-TOPSIS and AHP-PROMETHEE combination. This study provides insights for managers and policymakers to improve LPG supply chain resilience in the post-pandemic era and during the global political crisis. |
