Some Asymptotic Properties of the Erlang-C Formula in Many-Server Limiting Regimes
Ragavendran Gopalakrishnan, Yueyang Zhong
This paper presents asymptotic properties of the Erlang-C formula in a spectrum of many-server limiting regimes. Specifically, we address an important gap in the literature regardi…
A Framework for the Joint Optimization of Assignment and Pricing in Mobility-on-Demand Systems with Shared Rides
Yang Liu, Qi Luo, Raga Gopalakrishnan +1
Mobility-on-Demand (MoD) systems have become a fixture in urban transportation networks, with the rapid growth of ride-hailing services such as Uber and Lyft. Ride-hailing is typic…
The Price of Indivisibility in Cake Cutting
Eshwar Ram Arunachaleswaran, Ragavendran Gopalakrishnan
We consider the problem of envy-free cake cutting, which is the distribution of a continuous heterogeneous resource among self interested players such that nobody prefers what some…
Impact of Detour-Aware Policies on Maximizing Profit in Ridesharing
Arpita Biswas, Ragavendran Gopalakrishnan, Theja Tulabandhula +3
This paper provides efficient solutions to maximize profit for commercial ridesharing services, under a pricing model with detour-based discounts for passengers. We propose greedy…
The Costs and Benefits of Sharing: Sequential Individual Rationality and Sequential Fairness
Ragavendran Gopalakrishnan, Koyel Mukherjee, Theja Tulabandhula
In designing dynamic shared service systems that incentivize customers to opt for shared rather than exclusive service, the traditional notion of individual rationality may be insu…
Demand Prediction and Placement Optimization for Electric Vehicle Charging Stations
Ragavendran Gopalakrishnan, Arpita Biswas, Alefiya Lightwala +3
Effective placement of charging stations plays a key role in Electric Vehicle (EV) adoption. In the placement problem, given a set of candidate sites, an optimal subset needs to be…
Managing Overstaying Electric Vehicles in Park-and-Charge Facilities
Arpita Biswas, Ragavendran Gopalakrishnan, Partha Dutta
With the increase in adoption of Electric Vehicles (EVs), proper utilization of the charging infrastructure is an emerging challenge for service providers. Overstaying of an EV aft…
Portfolio Allocation for Sellers in Online Advertising
Ragavendran Gopalakrishnan, Eric Bax, Krishna Prasad Chitrapura +1
In markets for online advertising, some advertisers pay only when users respond to ads. So publishers estimate ad response rates and multiply by advertiser bids to estimate expecte…
Potential Games are Necessary to Ensure Pure Nash Equilibria in Cost Sharing Games
Ragavendran Gopalakrishnan, Jason R. Marden, Adam Wierman
We consider the problem of designing distribution rules to share "welfare" (cost or revenue) among individually strategic agents. There are many known distribution rules that guara…
Routing and Staffing when Servers are Strategic
Ragavendran Gopalakrishnan, Sherwin Doroudi, Amy R. Ward +1
Traditionally, research focusing on the design of routing and staffing policies for service systems has modeled servers as having fixed (possibly heterogeneous) service rates. Howe…
A class of equivalent idle-time-order-based routing policies for heterogeneous multi-server systems
Sherwin Doroudi, Ragavendran Gopalakrishnan
We consider an M/M/N/K/FCFS system (N>0, K>=N), where the servers operate at (possibly) heterogeneous service rates. In this situation, the steady state behavior depends on the rou…
Cache Me If You Can: Capacitated Selfish Replication Games in Networks
Ragavendran Gopalakrishnan, Dimitrios Kanoulas, Naga Naresh Karuturi +3
In Peer-to-Peer (P2P) network systems, content (object) delivery between nodes is often required. One way to study such a distributed system is by defining games, which involve sel…
