摘要:

For dual methods of multilevel optimization local applicability conditions which secure both the existence of unique local solutions of the subproblems and the validity of the strong local duality are given. Using an augmented Lagrangian function the reduction of the conditions to the well-known sufficient optimality conditions and the strict complementarity assumption is possible. Connections of the local duality with a local perturbation theory are shown, and properties of the dual problem and the perturbation function considered.

摘要:

Following ideas of V. Nollau and A. Hahnewald-Busch (cp. [17], [18], [19]) we develop a method of clustering state- and action-spaces of General Markovian Decision Problems into finitely many subsets serving as states and actions of approximating finite Markovian Decision-Problems. And we show that under suitable assumptions the value-functions of our constructed problems approximate those of the original one in a uniform sense.

摘要:

For a multidimensional, stochastic, dynamic storage system with mixed autocorrelated processes of demand we give sufficient conditions, that an optimal control of the system can be carried out by a onedimensional (z, Z) strategy. This strategy we can understand as well a generalization of a onedimensional (z , Z) strategy - a genernlization of a (s, S) strategy as a generalizatinn of a multidimensional (θ, S) strategy. The given sufficient conditions can be reduced in natural manner to well-known conditions in the special cases independent “demand” or “onedimensional system”. The present paper contains therefore the results of [7] and the case with finite horizont in [6].

摘要:

The most important characteristics of the open M/GI/1 queue, as steady-state probabilities, mean queue length, waiting time distribution are limits of the corresponding characteristics in closed (n/M/GI/1) queues with homogeneous customers if the summarized arrival intensity is constant and if n increases to infinity. In all cases the convergence is monotone thus permitting estimates for the (n/M/GI/1) characteristics if n is large.
