Stochastic programming for decentralized newsvendor with transshipment

Summerfield, Nichalin S.; Dror, Moshe - In: International Journal of Production Economics 137 (2012) 2, pp. 292-303

This paper discusses a family of two-stage decentralized inventory problems using a unifying framework (taxonomy) depicted as a multilevel graph. This framework allows us to model and link different problems of competing retailers who independently procure inventory in response to uncertain...

On service degrade at a discount: Capacity, demand pooling, and optimal discounting

Su, Ping; Tian, Zhongjun; Wang, Haiyan - In: Omega 40 (2012) 3, pp. 358-367

In this paper we study the capacity investment decisions and operational strategies of a firm providing two-class services facing uncertain demands. The capacity decisions of the resources are made before demands are observed. Each service can be implemented by its corresponding resource. Should...

A multi-stage stochastic supply network design problem with financial decisions and risk management

Nickel, Stefan; Saldanha-da-Gama, Francisco; Ziegler, … - In: Omega 40 (2012) 5, pp. 511-524

In this paper, a multi-period supply chain network design problem is addressed. Several aspects of practical relevance are considered such as those related with the financial decisions that must be accounted for by a company managing a supply chain. The decisions to be made comprise the location...

A multivariate adaptive regression splines cutting plane approach for solving a two-stage stochastic programming fleet assignment model

Pilla, Venkata L.; Rosenberger, Jay M.; Chen, Victoria; … - In: European Journal of Operational Research 216 (2012) 1, pp. 162-171

dispatch to reallocate aircraft closer to the departure of the aircraft. Traditionally, two-stage stochastic programming … leg based on forecasts taken six to twelve weeks prior to departure. Therefore, in this paper, a two-stage stochastic … programming framework has been developed to model the uncertainty in demand, along with the Boeing concept of demand driven …

Algorithm for the Stochastic Generalized Transportation Problem

Anholcer, Marcin - In: Operations Research and Decisions 22 (2012)

The Equalization method for the Stochastic Generalized Transportation Problem is presented. The algorithm allows to find the optimal solution to the problem of minimizing the expected total cost in the Generalized Transportation Problem with random demand. It is shown that the method is...

Medium-term Planning for Thermal Electricity Production.

Kovacevic, Raimund M.; Paraschiv, Florentina - School of Finance, Universität St. Gallen - 2012

In the present paper we demonstrate a mid-term planning model for thermal power generation which is based on multistage stochastic optimization and involves stochastic electricity spot prices, mixture of fuels with stochastic prices, the effect of CO2 emission prices and various types of further...

Optimal offering strategy for a concentrating solar power plant

Dominguez, R.; Baringo, L.; Conejo, A.J. - In: Applied Energy 98 (2012) C, pp. 316-325

This paper provides a methodology to build offering curves for a concentrating solar power plant. This methodology takes into account the uncertainty in the thermal production from the solar field and the volatility of market prices. The solar plant owner is a price-taker producer that...

Risk constrained self-scheduling of hydro/wind units for short term electricity markets considering intermittency and uncertainty

Moghimi Ghadikolaei, Hadi; Ahmadi, Abdollah; Aghaei, Jamshid - In: Renewable and Sustainable Energy Reviews 16 (2012) 7, pp. 4734-4743

In view of the intermittency and uncertainty associated with both the electricity production sector of restructured power system and their competitive markets, it is necessary to develop an appropriate risk managing scheme. So that it is desirable to trade-off between optimum utilization of...

Shelter location and transportation planning under hurricane conditions

Li, Anna C.Y.; Nozick, Linda; Xu, Ningxiong; Davidson, … - In: Transportation Research Part E: Logistics and … 48 (2012) 4, pp. 715-729

This paper develops a scenario-based bilevel programming model to optimize the selection of shelter locations with explicit consideration of a range of possible hurricane events and the evacuation needs under each of those events. A realistic case study for the state of North Carolina is...
