The worldwide rivalry of commerce leads organizations to focus on selecting the best project portfolio among available projects through utilizing their scarce resources in the most effective manner. To accomplish this, organizations should consider the intrinsic uncertainty in projects on the basis of an appropriate evaluation technique with regard to the flexibility in investment decision-maki...
Spatial decision support systems (SDSS) are designed to make complex resource allocation problems more transparent and to support the design and evaluation of allocation plans. Recent developments in this field focus on the design of allocation plans using optimization techniques. In this paper we analyze how uncertainty in spatial (input) data propagates through, and affects the results of, an...
<p>Intelligent evolutionary algorithm is an important method to solve optimization problems. Most of their inspiration comes from the laws nature and biology. This paper proposes a new intelligent based on life habits Rafflesia, which called Rafflesia Optimization Algorithm. It mainly consists three stages: attracting insects, swallowing spreading seeds. In first stage, ROA performs local...
Operations Research has addressed a variety of environmental problems outside the traditional supply chain management area such as remanufacturing, reverse logistics, and waste management. Supply chain sustainability, which includes designing green supply chains, will gain much more attention in the future. Indeed, most companies are still in the early stage of considering a green initiative. T...
Facility location-allocation models are used in a widespread variety of applications to determine the number of required facility along with the relevant allocation process. In this paper, a new mathematical model for the capacitated multi-facility location-allocation problem with probabilistic customer's locations and fuzzy customer’s demands under the Hurwicz criterion is proposed. Thi...
hub location problems are among the extensions ofclassical location problems that have numerous applications in designingtransportation, postal, and telecommunication networks. despite the evidentattention of researchers to these problems, there are few studies on designinghub networks under uncertainty and disruption. in this study, the capacitatedsingle allocation hub location problem under d...
This special issue of European Journal of Operational Research is devoted to the ECCO XV Conference, the fifteen annual meeting of the European Chapter on Combinatorial Optimization, held at the University of Lugano (Switzerland), from May 30 to June 1, 2002. ECCO, the EURO Working Group on Combinatorial Optimization, was created in 1987 by C. Roucairol, D. De Werra and A. Rinnooy Kan. It provi...
Facility location decisions play a prominent role in strategic planning of many firms, companies and governmental organizations. Since in many real-world facility location problems, the data are subject to uncertainty, in this paper, we consider the P-center problem under uncertainty of demands. Using Bertsimas and Sim approach, we develop a robust model of the problem as an integer programming...
