Forecasting Demand of Potential Factors in Data Centers
PINNOW, Alexander; OSTERBURG, Stefan; HANISCH, Lars - In: Informatica Economica 13 (2009) 1, pp. 9-15
This paper deals with forecasting demand of potential factors in data centers. Firstly it will define factors themselves and their importance in the process of data centers. Then it will be shown how three standard forecasting methods can be applied for predicting capacity needs in data centers.

Budget Allocation for Permanent and Contingent Capacity under Stochastic Demand.
Mincsovics, Gergely; Jeunet, Jully; Dellaert, Nico - Université Paris-Dauphine - 2011
We develop a model of budget allocation for permanent and contingent workforce under stochastic demand. The level of permanent capacity is determined at the beginning of the horizon and is kept constant throughout, whereas the number of temporary workers to be hired must be decided in each...

The costs of electricity systems with a high share of fluctuating renewables - a stochastic investment and dispatch optimization model for Europe
Nagl, Stephan; Fürsch, Michaela; Lindenberger, Dietmar - Energiewirtschaftliches Institut (EWI), Universität zu … - 2012
Renewable energies are meant to produce a large share of the future electricity demand. However, the availability of wind and solar power depends on local weather conditions and therefore weather characteristics must be considered when optimizing the future electricity mix. <p>In this article we...</p>

Combining stochastic programming and optimal control to solve multistage stochastic optimization problems
Barro, Diana; Canestrelli, Elio - Dipartimento di Economia, Università Ca' Foscari Venezia - 2011
In this contribution we propose an approach to solve a multistage stochastic programming problem which allows us to obtain a time and nodal decomposition of the original problem. This double decomposition is achieved applying a discrete time optimal control formulation to the original stochastic...
