Application of the Simulated Annealing Algorithm for Transport Infrastructure Planning
Decisions in planning for transport infrastructure are the result of complex technical, political, and societal concerns. Its context of limited public funding and large costs require that decision making is soundly supported. When addressing real-world problems, however, it is extremely difficult to ascertain the system configuration yielding the most value. Different alternatives exist that trade-off interrelated factors governing the value of the configurations. Metaheuristics can be of assistance when solving such real-world problems. This chapter presents an application of the simulated annealing algorithm to solve an integrated approach to high-speed rail planning. The algorithm capabilities in addressing the intricacies imposed by large and complex problems are discussed.
