Skiing and Modeling

Looker room layouts

One of my favorite winter activities is skiing and now that all the skiing places in the North East have closed (for those interested Killington, VT closed last Saturday), I thought it would be interesting to see how people have using various modeling techniques to explore ski areas. While what follows is not a comprehensive list of all the works, these are some that I have come across. If you know more, feel free to leave a comment below. 

Models have ranged form looking at the spatial arrangement  of locker rooms at ski resorts (Gao et al., 2024) to lift lines  (congestion) in places such as  La Plagne in the  French Alps (Poulhès and Mirial, 2017) or the Austrian ski resort of Fanningberg (Heinrich et al., 2023). Others have simulated entire ski areas including lift lines, slopes used etc. (Kappaurer 2022). While Pons et al., (2014) developed an agent based model to see how climate change might impact where skies go. Others have explored how climate change might impact ski areas and their associated water usage for making snow (e.g., Soboll and Schmude 2011). Keeping the climate theme, Revilloud et al., (2013) have used agent-based simulations to simulate snow hight on ski runs based on skiers movements in order to facilitate snow cover management (i.e., reduce the production cost of artificial snow and thus water and energy consumption). Murphy (2021) developed a more simple agent-based model of how skiers might ski durring a powder day and explores the area of terrain they may cover based on ability.

Similar to some of the other models above, but in light of COVID19, Integrated Insight (2020), a analytics consulting company shows in the movie below how one can use simulation to explore crowd management in the base areas of ski resorts.
