Differential Stability of Two-Stage Stochastic Programs [PDF]
SIAM Journal on Optimization, 2000 Summary: Two-stage stochastic programs with random right-hand side are considered. Optimal values and solution sets are regarded as mappings of the expected recourse functions and their perturbations, respectively. Conditions are identified implying that these mappings are directionally differentiable and semidifferentiable on appropriate functional ...

A Stochastic Programming Approach for a Multi-Site Supply Chain Planning in Textile and Apparel Industry under Demand Uncertainty [PDF]
International Journal of Supply and Operations Management, 2015 In this study, a new stochastic model is proposed to deal with a multi-product, multi-period, multi-stage, multi-site production and transportation supply chain planning problem under demand uncertainty. A two-stage stochastic linear programming approach

Neur2SP: Neural Two-Stage Stochastic Programming
Advances in Neural Information Processing Systems 35, 2022 Stochastic Programming is a powerful modeling framework for decision-making under uncertainty. In this work, we tackle two-stage stochastic programs (2SPs), the most widely used class of stochastic programming models. Solving 2SPs exactly requires optimizing over an expected value function that is computationally intractable.

Appointment Scheduling at Outpatient Clinics Using Two-Stage Stochastic Programming Approach
IEEE Access, 2020 Clinics with a large volume of patients are often burdened with limited resources such as nurses and providers. Also, an efficient health system seeks short wait times for the patients to see the provider (indirect wait time) and within the clinic ...
