An advanced analytical framework for improving customer satisfaction: A case of air passengers

Having an appropriate and advanced analytical framework is essential for transport service managers to optimize resource allocation to improve customer satisfaction. This study proposes a novel analytical framework, the “Importance-Performance-Impact Analysis” (IPIA), which aims to overcome several conceptual and methodological shortcomings associated with Importance-Performance Analysis (IPA). The IPIA framework integrates advanced analytical techniques, such as Back Propagation Neural Network and Decision-Making Trial and Evaluation Laboratory (DEMATEL/ANP). We illustrate IPIA in one of the 'Big Four' airlines in China. IPIA Table and IPIA Matrix help transportation managers to allocate resources better than IPA to improve customer satisfaction.
