Empowering Volleyball with Data Science
The proposed open-source Python-based toolbox extends the PyDataVolley library to provide comprehensive tools for volleyball data analysis. It enables advanced processing, visualization, and analysis of scouting data, integrating various state-of-the-art analytical methods. This approach allows coaches and analysts to gain deeper, actionable insights into team and player performance, fostering data-driven decision-making.
The system converts raw Data Volley (.dvw) files into a structured CSV format, enhancing compatibility with modern data science pipelines. It includes modules for custom performance metrics, machine learning-based clustering, multi-criteria decision analysis, and Markov chain modeling, providing a versatile framework for understanding game dynamics.
End-to-End Data Processing & Analysis Workflow
Our methodology transforms raw scouting files into actionable intelligence through a robust, Python-based pipeline. This ensures data consistency, enriches datasets with crucial metadata, and applies advanced analytical models to uncover hidden patterns and predict outcomes.

Customizable Performance Metrics for Tactical Depth
Our toolbox allows for the definition of custom efficiency metrics, balancing successful and unsuccessful actions. These metrics can be tailored to specific strategic priorities or training objectives, providing a granular view of team and player performance across various game actions such as serve, reception, attack, block, and defense.
0.86
Correlation between Overall Attack Efficiency (AE) and Final Team Ranking, highlighting its critical role in success.
Overall Attack Efficiency (AE) emerged as the strongest determinant of team ranking with a correlation of 0.86. This emphasizes the paramount importance of offensive performance. Furthermore, First Ball Side-Out (FBSO) and Attack After Service Turn (AST) also showed substantial correlations (0.65 and 0.70 respectively), underscoring the necessity of converting serve-receive and post-serve situations into points.
Integrating Machine Learning and Decision Analysis for Deeper Insights
Beyond traditional statistics, our toolbox incorporates sophisticated analytical models. Machine learning clustering techniques (K-Means, Gaussian Mixture Model, Agglomerative Clustering) identify natural team groupings, while Multi-Criteria Decision Analysis (AHP, TOPSIS, PROMETHEE, MOORA) constructs robust team rankings based on aggregated performance indicators. Markov Chain models are used to analyze rally dynamics, capture recurring transition patterns, and estimate outcome probabilities from different game states.
This integration of diverse analytical methods provides a multi-faceted approach to understanding the complex dynamics of volleyball matches, offering a significant advantage over tools limited to basic statistical reporting.

Case Study: 2025 Italian Cup Final - Consolini Volley vs. Trentino Volley
Strategic Impact in Action: How Data Analytics Changed the Game
Our toolbox was critically validated through a detailed analysis for the 2025 Italian Cup final. Pre-match analysis revealed Consolini Volley's seasonal superiority across most fundamental metrics, particularly in blocking and attacking. Their strong performance in longer rallies (61.7% win rate for rallies > 12 touches) and effective 'XX' fastball attacks were key strengths.
However, Trentino Volley, informed by strategic insights generated through our toolbox, implemented a targeted tactical strategy that effectively challenged Consolini's gameplay. This proactive, data-driven approach led to a measurable performance decline for Consolini Volley across almost all key indicators during the final match, despite their historical superiority.
For instance, Consolini's Overall Attack Efficiency (AE) dropped from its seasonal average of 0.2478 to 0.2216 (a -0.0262 deviation), and their FBSO dropped significantly from 0.2034 to 0.0738 (a -0.1296 deviation). Trentino, while not overall superior, saw a positive deviation in Service Efficiency (+0.1856), indicating a targeted tactical adjustment.
Key Learning: This case study unequivocally demonstrates how accessible, customizable, and reproducible data analytics tools can significantly impact competitive outcomes by enabling informed, adaptive tactical decision-making.
