Der gegenwärtige Stand der stochastischen ProgrammierungUnternehmensforschung - Tập 12 - Trang 81-95 - 1968

Wenn in einem linearen Programm einige oder alle Koeffizienten Zufallsvariable sind, verliert die Zielsetzung dieses linearen Programmes offenbar ihren Sinn. Die dann auftretenden neuen Problemstellungen, die bisher in der Literatur behandelt wurden, sollen in dieser Arbeit diskutiert werden: Das Verteilungsproblem, das Programm mit Wahrscheinlichkeitsrestriktionen und das zweistufige Problem.
Optimal control of processes governed by partial differential equations part II: VibrationsUnternehmensforschung - Tập 26 - Trang 63-86 - 1982
W. Krabs
This paper is concerned with damping of vibrations of one-dimensional media by distributed or boundary control. Given an initial state of vibration at the timet=0, the problem is considered to find a control along the medium or on its boundary by which the initial state is transferred to the position of rest at some given timeT>0. At first the problem of null-controllability is studied where the c...... hiện toàn bộ

Es wird eine große Klasse von linearen Kontrollproblemen unter einem einheitlichen Gesichtspunkt betrachtet. Wir geben hierfür ein allgemeines Lösungsprinzip an. Wichtige Spezialfälle werden näher erläutert und die resultierenden Rechenvorschriften angegeben.
A review of multi-component maintenance models with economic dependenceUnternehmensforschung - Tập 45 - Trang 411-435 - 1997
Rommert Dekker, Ralph E. Wildeman, Frank A. van der Duyn Schouten
In this paper we review the literature on multi-component maintenance models with economic dependence. The emphasis is on papers that appeared after 1991, but there is an overlap with Section 2 of the most recent review paper by Cho and Parlar (1991). We distinguish between stationary models, where a long-term stable situation is assumed, and dynamic models, which can take information into account...... hiện toàn bộ
Analysis of a discrete-time queue with general independent arrivals, general service demands and fixed service capacityUnternehmensforschung - Tập 82 - Trang 285-315 - 2015
H. Bruneel, W. Rogiest, J. Walraevens, S. Wittevrongel
This paper analyzes a single-server discrete-time queueing model with general independent arrivals, where the service process of the server is characterized in two steps. Specifically, the model assumes that (1) each customer represents a random, arbitrarily distributed, amount of work for the server, the service demand, and (2) the server disposes of a fixed number of work units that can be execu...... hiện toàn bộ
