Abstract

Advances in data-driven decision-making have significantly transformed the processes of contract negotiation and supplier selection, especially within complex and dynamic procurement environments. This explores recent technological and methodological developments that leverage data analytics, artificial intelligence (AI), and machine learning to enhance the effectiveness, efficiency, and transparency of these critical procurement activities. Traditional supplier selection and contract negotiation methods, often reliant on subjective judgments and limited data, are increasingly being replaced or augmented by quantitative, evidence-based approaches that utilize vast datasets from internal and external sources. Key advances include the application of predictive analytics to forecast negotiation outcomes, optimize contract terms, and mitigate risks. Natural language processing (NLP) techniques facilitate automated contract review, enabling rapid identification of potential issues and inconsistencies. Machine learning algorithms improve supplier evaluation by integrating multiple criteria such as cost, quality, delivery performance, and risk factors, providing a holistic and dynamic supplier scoring system. Additionally, the integration of big data from real-time supply chain monitoring, financial indicators, and market trends supports more informed and timely decision-making. Emerging digital tools, including AI-powered negotiation assistants, procurement management platforms, and blockchain technology, offer enhanced transparency, traceability, and collaboration between buyers and suppliers. These innovations contribute to cost reductions, improved supplier relationships, and greater resilience in supply chains. Despite these promising developments, challenges remain, including data quality and integration issues, privacy concerns, and organizational resistance to change. This highlights the need for continued research on integrating environmental, social, and governance (ESG) metrics into data-driven frameworks and advancing adaptive, real-time decision-making models. This review synthesizes current trends and practical applications, offering valuable insights for academics, procurement professionals, and policymakers aiming to harness data-driven strategies to optimize contract negotiation and supplier selection processes in increasingly global and competitive markets.
