Analyzing Supply Chain Risk Mitigation Strategies in High-Technology Industries A DEMATEL Approach

This study investigates supply chain risk mitigation strategies in high-technology industries using the Decision-Making Trial and Evaluation Laboratory (DEMATEL) method.The research focuses on five key strategies: Supplier Diversification Strategy, Real-Time Monitoring System, Dual Sourcing Policy, Inventory Buffering, and Collaborative Risk Sharing Contracts.Given the complex and interconnected nature of hightechnology supply chains, understanding the relationships and effectiveness of these strategies is crucial for maintaining operational resilience.The DEMATEL analysis reveals significant insights into the cause-effect relationships between different mitigation strategies.The total relation matrix demonstrates that Supplier Diversification Strategy has the highest total influence value (-5.36), indicating its substantial impact on other strategies, particularly on Dual Sourcing and Inventory Buffering.The study also finds that Collaborative Risk Sharing Contracts, while ranking first in priority, shows lower total impact values , suggesting its role as a supportive rather than driving strategy.The research identifies that all five strategies function primarily as "effect" components, with varying degrees of influence on each other.The normalized direct relation matrix shows strong relationships between certain strategy pairs, such as Supplier Diversification's influence on Dual Sourcing (0.727) and Inventory Buffering (0.545).The findings suggest that an integrated approach to risk mitigation is essential, where strategies complement and reinforce each other rather than operating in isolation.This study contributes to the understanding of supply chain risk management in high-technology industries by providing a quantitative assessment of strategy interdependencies.The results can guide decision-makers in prioritizing and implementing risk mitigation strategies while considering their interconnected nature.
