Heuristics for Multi-Vehicle Routing Problem Considering Human-Robot Interactions
Venkata Sirimuvva Chirala, Kaarthik Sundar, Saravanan Venkatachalam +2
Unmanned ground vehicles (UGVs) are being used extensively in civilian and military applications for applications such as underground mining, nuclear plant operations, planetary ex…
Robust flight schedules with stochastic programming
Sujeevraja Sanjeevi, Saravanan Venkatachalam
Limiting flight delays during operations has become a critical research topic in recent years due to their prohibitive impact on airlines, airports, and passengers. A popular strat…
Managing access to primary care clinics using robust scheduling templates
Sina Faridimehr, Saravanan Venkatachalam, Ratna Babu Chinnam
An important challenge confronting healthcare is the effective management of access to primary care. Robust appointment scheduling policies/templates can help strike an effective b…
Two-stage stochastic programming approach for path planning problems under travel time and availability uncertainties
Saravanan Venkatachalam, Manish Bansal, Jonathon M. Smereka +1
Significant advances in sensing, robotics, and wireless networks have enabled the collaborative utilization of autonomous aerial, ground and underwater vehicles for various applica…
A Two-Stage Approach for Routing Multiple Unmanned Aerial Vehicles with Stochastic Fuel Consumption
Saravanan Venkatachalam, Kaarthik Sundar, Sivakumar Rathinam
The past decade has seen a substantial increase in the use of small unmanned aerial vehicles (UAVs) in both civil and military applications. This article addresses an important asp…
A Stochastic Programming Approach for Electric Vehicle Charging Network Design
Sina Faridimehr, Saravanan Venkatachalam, Ratna Babu Chinnam
Advantages of electric vehicles (EV) include reduction of greenhouse gas and other emissions, energy security, and fuel economy. The societal benefits of large-scale adoption of EV…
Branch-and-price algorithm for an auto-carrier transportation problem
Saravanan Venkatachalam, Kaarthik Sundar
Original equipment manufacturers (OEMs) manufacture, inventory and transport new vehicles to franchised dealers. These franchised dealers inventory and sell new vehicles to end use…
Absolute semi-deviation risk measure for ordering problem with transportation cost in Supply Chain
Saravanan Venkatachalam, Lewis Ntaimo
We present a decomposition method for stochastic programs with 0-1 variables in the second-stage with absolute semi-deviation (ASD) risk measure. Traditional stochastic programming…
Integer Set Reduction for Stochastic Mixed-Integer Programming
Saravanan Venkatachalam, Lewis Ntaimo
Two-stage stochastic mixed-integer programming (SMIP) problems with general integer variables in the second-stage are generally difficult to solve. This paper develops the theory o…
