Analysis and Prediction of Delivery Reliability in the Retail Sector
Robert SZCZUR, Patrycja GUZANEK, Anna BORUCKA
Abstract. This study analyzes delivery reliability in the retail sector, focusing on delivery completeness and losses over time. Using descriptive statistics, ANOVA, the Kruskal-Wallis test, and Tukey’s post-hoc comparisons, the research found no significant monthly or seasonal variations. The correlation between order volume and delivery completeness was also insignificant, indicating that disruptions are incidental rather than cyclical. These results suggest that risk management should focus on identifying and eliminating one-off issues, while stable logistics processes provide a solid basis for continuous improvement in supply chain performance.
