چکیده
Given a stochastic state process $(X_t)_t$ and real-valued submartingale cost $(S_t)_t$, we characterize optimal stopping times $\tau$ that minimize the expectation of $S_\tau$ while realizing given initial target distributions $\mu$ $\nu$, i.e., $X_0\sim \mu$ $X_\tau \sim \nu$. A dual optimization problem is considered shown to be attained under suitable conditions. The solution then provides contact set, which characterizes location where can occur. time uniquely determined as first hitting this set provided assume natural structural assumption on pair $(X_t, S_t)_t$, generalizes

Martingale Optimal Transport with Stopping
We solve the martingale optimal transport problem for cost functionals represented by optimal stopping problems. The measure-valued martingale approach developed in ArXiv: 1507.02651 allows us to obtain an equivalent infinitedimensional controller-stopper problem. We use the stochastic Perron’s method and characterize the finite dimensional approximation as a viscosity solution to the correspon...
متن کاملNumerical Approximations of Stochastic Optimal Stopping and Control Problems
We study numerical approximations for the payoff function of the stochastic optimal stopping and control problem. It is known that the payoff function of the optimal stopping and control problem corresponds to the solution of a normalized Bellman PDE. The principal aim of this thesis is to study the rate at which finite difference approximations, derived from the normalized Bellman PDE, converg...
متن کاملMinimizing earliness and tardiness costs in stochastic scheduling
We address the single-machine stochastic scheduling problem with an objective of minimizing total expected earliness and tardiness costs, assuming that processing times follow normal distributions and due dates are decisions. We develop a branch and bound algorithm to find optimal solutions to this problem and report the results of computational experiments. We also test some heuristic procedur...
متن کاملMinimizing Risk Costs through Optimal Responses in NPD Projects
In rapidly changing market environment, firms are investing a lot of time and resources into new product development (NPD) projects to make profit and to obtain competitive advantage. However, failure rate of NPD projects is becoming high due to various internal and external risks which hinder successful NPD projects. To reduce the failure rate, it is critical that risks have to be managed effe...
متن کاملFinite Difference Approximation for Stochastic Optimal Stopping Problems with Delays
This paper considers the computational issue of the optimal stopping problem for the stochastic functional differential equation treated in [4]. The finite difference method developed by Barles and Souganidis [2] is used to obtain a numerical approximation for the viscosity solution of the infinite dimensional Hamilton-Jacobi-Bellman variational inequality (HJBVI) associated with the optimal st...
