Modeling and Optimization in Resource Sharing Systems: Application to Bike-Sharing with Unequal Demands

Service Network Design of Bike Sharing Systems with Resource Constraints

Balancing Bike Sharing Systems

Bike Sharing Systems became popular in recent years to extend the public transportation network of cities or regions. Most research in this area focuses on finding the optimal locations for bike sharing stations. Still various approaches on how to operate such a system efficiently exist. The usefulness of a bike sharing system strongly depends on the user convenience which is directly connected...

Rebalancing Dockless Bike Sharing Systems

Bike sharing provides an environment-friendly way for traveling and is booming all over the world. Yet, due to the high similarity of user travel patterns, the bike imbalance problem constantly occurs, especially for dockless bike sharing systems, causing significant impact on service quality and company revenue. Thus, it has become a critical task for bike sharing systems to resolve such imbal...

Mutual Insurance Networks and Unequal Resource Sharing

We study formation of mutual insurance networks in a model where agents who obtain more resources share a fixed amount of resources with all directly linked agents that obtain fewer resources. We identify the pairwise stable networks and efficient networks in a basic model where agents are identical. Then, we introduce in the model two types of heterogeneity: an exogenous one, where agents diff...

Networks as Signals, with an Application to Bike Sharing System

Dynamic graphs are commonly used for describing networks with a time evolution. Shimada et al. [1] recently proposed to transform these graphs into a collection of signals indexed by vertices. This approach is here further explored in a number of different directions. First, the importance of a good indexing of a graph is stressed, and a solution is proposed using a node labeling algorithm whic...
