Abstract:The focus of this project was on supplying gasoline after a natural disaster. There were two aspects for this work: determination of which gas stations should be provided with generators (among those that do not have electric power) and determination of a delivery scheme that accounts for increased demand due to lack of public transportation and considerations such as equity. A Mixed -Integer Mathematical formulation was developed for this situation. Two case studies based on Hurricane Sandy in New Jersey are develop ed and solved in CPLEX. This project utilized the limited supply of back -up generators and optimized the generators assignment and truck deliveries to the gas stations to achieve maximum gasoline delivery, while ensuring equity factor across the different regions. The model works effectively to locate generators to gas stations and assigns delivery trucks to gas stations. Via the New Jersey 2-county case study our study shows that different combinations of two types of trucks can affect the performance significantly. Different input parameters, e.g. available resource, number of generators, equity parameter affect the deliverable results. From the large case-study we conclude that our model is quite efficient and useful to manage gasoline delivery in the aftermath of a natural disaster.
