 =Context and Importance=
 Artificial snowmaking is a critical process for maintaining the operation of ski resorts, especially during periods with insufficient natural snowfall. With increasing climate change, rising temperatures, and irregular precipitation patterns, artificial snowmaking has become a key tool for ensuring the quality of ski slopes. Effective snowmaking requires careful planning and management to minimize water, energy, and time costs while maintaining environmental sustainability.
