Optimization Models for Rail Car Fleet Management represents the result of multi-year efforts to provide readers with insights into one of the most important areas of railway transport management. The book covers mathematical procedures for the effective and efficient utilization of railway freight cars, developed models for optimization methods, heterogeneity and partial substitutability of freight cars, research and development in rail freight car fleet management models, and the stochastic and dynamic nature of the supply, demand and traveling time of freight cars, among other topics.
- Summarizes the authors past research efforts in the field of rail freight car fleet management
- Presents various approaches that include the application of a variety of optimization techniques
- Contains centralized, decentralized, distributed perspectives considered under the assumption of deterministic, stochastic, fuzzy and fuzzy stochastic parameters
Transportation Engineers, Traffic Engineers, Traffic System Designers, and Highway Engineers as well as undergraduate and graduate students in these fields
