The aim of this paper is to investigate the Lagrangian approach and a related Linear Programming (LP) that appear in constrained Markov decision processes (CMDPs) with a countable state space and total expected cost criteria (of which the expected discounted cost is a special case). We consider...

In this paper, we extend the concept of cone-convexlikeness of single-valued maps to set-valued maps and study super efficiency in cone-convexlike vector optimization with set-valued maps. Under the assumption of the cone-convexlikeness, some characterizations of super efficiency are established...

To reduce the risk of disruption of lifeline systems during the emergency following an earthquake (or any other disaster) preventive interventions on the existing concerned facilities are necessary, but often hindered by the limitation of the available economic resources. In this paper,...

This paper deals with the super efficient sets in vector optimization of set-valued maps. It is proved that these sets are connected under an assumption of cone-convexlikeness and upper semicontinuity. Copyright Springer-Verlag Berlin Heidelberg 1998

The generalized contingent epiderivative of set-valued maps is introduced in this paper and its relationship to the contingent epiderivative is investigated. A unified necessary and sufficient optimality condition is derived in terms of the generalized contingent epiderivative. The existence of...

The maximum packing (MP) policy for dynamic channel assignment in cellular radio communication systems specifies that a new call attempt is admitted whenever there is some way of rearranging channels so that every call can be carried. Otherwise the call is blocked and removed from the system. We...

We consider the problem of control for continuous time stochastic hybrid systems in finite time horizon. The systems considered are nonlinear: the state evolution is a nonlinear function of both the control and the state. The control parameters change at discrete times according to an underlying...

This paper att empts to give a unified approach to the existing three types of variational principles for vector valued functions: A. B. Nemeth (1986), Chr. Tammer (1992) and G. Isac (1996). Some of the results we obtain are variants of the authors' mentioned above. Some are even stronger than...

Optimal control problem for linear two-dimensional (2-D) discrete systems with mixed constraints is investigated. The problem under consideration is reduced to a linear programming problem in appropriate Hubert space. The main duality relations for this problem is derived such that the...

One of the main difficulties in nonsmooth analysis is to devise calculus rules. It is our purpose here to show that a certain cooperative behavior between functions (resp. sets, resp. multifunctions) yields calculus rules for subdifferentials (resp. normal cones, resp. coderivatives). In...
