A Study of Delivery Route Optimization for Artistic Lighting Systems for Cultural Tourism in High-altitude Cold Areas at Night

The artistic lighting system for high-altitude cold areas is a set of intelligent night-lighting equipment that can be used for night tourism in high-altitude cold areas. In order to ensure the normal and stable delivery of artistic lighting systems to the actual high-altitude icy/snowy areas, methods such as theoretical research, experimental analysis, modeling, algorithm improvement, and case study are adopted to study the delivery of artistic lighting systems in high-altitude cold conditions. Based on the actual demand for the delivery of artistic lighting systems to high-altitude icy/snowy areas, the Fuzzy Time-Windows constraint is formulated; the objective functions for maximizing customer satisfaction with artistic light shows and minimizing the total cost of the delivery of lighting systems are designed; customer satisfaction with light shows is converted into a constraint and thus a single objective function is established. Based on the single objective function, a static initial model with time window constraints is constructed. The Shennongjia International Ski Resort in Hubei Province is selected for empirical analysis. Based on the static initial model and dynamic model constructed by using the genetic algorithms for nonlinear programming, three analyses are completed. According to the analyses, the cost of a single light show using the artistic lighting systems is relatively low, and as the places in need of lighting systems increase, the cost of artistic lighting systems will be increasingly lower than that of fixed light sources.
