In this paper we apply a new framework for the study of monotonicity in queueing systems to stochastic scheduling models. This allows us a unified treatment of many different models, among which are multiple and single server models (with and without feedback), discrete and continuous time...

Pareto equilibria in multicriteria games can be computed as the Nash equilibria of scalarized games, obtained by assigning weights to the separate criteria of a player. To analysts, these weights are usually unknown. This paper therefore proposes ideal equilibria, strategy profiles that are...

In this paper we study situations where asymmetric players have restricted possibilities for communication. Extreme asymmetry results in a hierarchy among the players. We introduce a class of allocation rules for these situations inspired by the Myerson value (Myerson (1977)) and Shapley values...

We consider the movement minimization problem in a conveyer flow shop processing controlled by one worker that has to serve all machines. Each machine can only execute tasks if the worker is present. A few jobs can be queued in a buffer in front of each machine. The objective is to minimize the...

We obtain the necessary and sufficient conditions of many kinds of proper efficiency in vector set-valued optimization by using the concept of contingent epiderivative introduced by Jahn and Rauh, also we disclose the closed relations between proper efficiency of vector set-valued optimization...

Problems with unit execution time tasks and two identical parallel processors have received a great deal of attention in scheduling theory. In contrast to the conventional models, where each task requires only one processor, we consider a situation when a task may require both processors...

We consider the problem of the perturbation of a class of linear-quadratic differential games with piecewise deterministic dynamics, where the changes from one structure (for the dynamics) to another are governed by a finite-state Markov process. Player 1 controls the continuous dynamics,...

We study the first-passage problem with multiple costs. We characterize an optimal deterministic stationary policy via the systems of linear inequalities and present a policy iteration algorithm for finding all optimal deterministic stationary policies. The algorithm is illustrated by a...

This paper describes a constrained optimization method that was inspired by the physical equivalent of a small ball that, propelled only by gravity, is dropped from an initial point inside a full-dimensional body, represented by the set of feasible solutions. The ball will eventually hit one of...

This paper considers an individual's problem and effects on savings for retirement. We show using a deterministic model, a linear utility function and assuming an individual can benefit from a tax break in savings, that under reasonable circumstances, there is only one switch from not saving to...
