This study optimizes bike-sharing systems using a stochastic model for dynamic demand, improving resource allocation and infrastructure planning. Effective cost management is key to meeting user travel needs efficiently.
Area of Science:
- Operations Research
- Transportation Science
- Urban Planning
Background:
- Bike-sharing systems face challenges with dynamic demand, exacerbated by events like the COVID-19 pandemic.
- Optimizing resource allocation and infrastructure is crucial for efficient bike-sharing operations.
Purpose of the Study:
- To develop a stochastic mathematical model for optimizing bike-sharing system resource allocation and infrastructure planning.
- To enhance system performance and resource utilization under varying demand scenarios.
- To ensure total travel demand fulfillment and assess network capacity.
Main Methods:
- Development of a stochastic mathematical model for bike-sharing station allocation and network design.
- Application of the model to the Vienna bike-sharing system for a case study.
- Conducting sensitivity analysis on cost parameters.
Main Results:
- The stochastic model effectively optimizes resource allocation and infrastructure planning for bike-sharing systems.
- Case study in Vienna demonstrates practical applicability and potential for improved efficiency and service quality.
