Probabilistic modeling of multiperiod service levels
Lejeune, Miguel A. - In: European Journal of Operational Research 230 (2013) 2, pp. 299-312
This study investigates multiperiod service level (MSL) policies in supply chains facing a stochastic customer demand. The objective of the supply chains is to construct integrated replenishment plans that satisfy strict stockout-oriented performance measures which apply across a multiperiod...

Stochastic capacity planning and dynamic network design
Pimentel, Bruno S.; Mateus, Geraldo R.; Almeida, Franklin A. - In: International Journal of Production Economics 145 (2013) 1, pp. 139-149
The present paper proposes a mathematical model and a solution approach to the Stochastic Capacity Planning and Dynamic Network Design Problem. Here, strategic decisions usually comprise developing the necessary capacity — through either incrementing capacity on existing assets (facilities or...

Computational aspects of minimizing conditional value-at-risk
Künzi-Bay, Alexandra; Mayer, János - In: Computational Management Science 3 (2006) 1, pp. 3-27
We consider optimization problems for minimizing conditional value-at-risk (CVaR) from a computational point of view, with an emphasis on financial applications. As a general solution approach, we suggest to reformulate these CVaR optimization problems as two-stage recourse problems of...

Capacity expansion and forward contracting in a duopolistic power sector
Chin, Dorea; Siddiqui, Afzal - In: Computational Management Science 11 (2014) 1, pp. 57-86
The surge in demand for electricity in recent years requires that power companies expand generation capacity sufficiently. Yet, at the same time, energy demand is subject to seasonal variations and peak-hour factors that cause it to be extremely volatile and unpredictable, thereby complicating...

Energy efficiency and risk management in public buildings: strategic model for robust planning
Cano, Emilio; Moguerza, Javier; Ermolieva, Tatiana; … - In: Computational Management Science 11 (2014) 1, pp. 25-44
Due to deregulations of the energy sector and the setting of targets such as the 20/20/20 in the EU, operators of public buildings are now more exposed to instantaneous (short-term) market conditions. On the other hand, they have gained the opportunity to play a more active role in securing...

Cost/risk balanced management of scarce resources using stochastic programming
Gaivoronski, Alexei; Sechi, Giovanni M.; Zuddas, Paola - In: European Journal of Operational Research 216 (2012) 1, pp. 214-224
We consider the situation when a scarce renewable resource should be periodically distributed between different users by a Resource Management Authority (RMA). The replenishment of this resource as well as users demand is subject to considerable uncertainty. We develop cost optimization and risk...

Multistage Stochastic Portfolio Optimisation in Deregulated Electricity Markets Using Linear Decision Rules
Rocha, Paula; Kuhn, Daniel - COMISEF - 2010
The deregulation of electricity markets increases the financial risk faced by retailers who procure electric energy on the spot market to meet their customers’ electricity demand. To hedge against this exposure, retailers often hold a portfolio of electricity derivative contracts. In this...
