2017年美国数学建模竞赛O奖获奖论文

2017美赛o奖论文，The objective of this model was to design an easy-to-use index that is capable of grading a city’s smart growth based on basic principles of sustainability. Because the ten principles of smart growth were established to include the three E’s of sustainability (environmental sustainability, economic prosperity, and social equity) this model incorporated all ten principles into five unique metrics based on the intersectionality of core ideas (top right figure). These metrics analyze a city’s: land use, housing, community, development plans, and transportation. The metrics themselves are determined using simple measures of widely available data. The sum of these metrics is reported as the Smart Growth Index (SGI) for any developed city. Sacramento, California (United States) and Edinburgh, Scotland (United Kingdom) were analyzed with the model to serve as regional benchmarks. Both cities were selected because each currently has smart growth principles incorporated into their city growth plans. After an initial analysis of both cities, new smart growth initiatives were developed and new model inputs were projected. These initiatives were aimed specifically towards each city to improve their overall SGI score (bottom right figure). The two cities both scored well initially with SGI scores of 44.7 and 54.9, respectively. After implementing the proposed initiatives, the SGI scores increased to 55.5 and 66.5, respectively. A 50% increase in population was also analyzed and, assuming that each city follows the new initiatives, each SGI metric is expected to increase.
