Shifting towards offshore wind energy—Recent activity and future development

Kaldellis, J.K.; Kapsali, M. - In: Energy Policy 53 (2013) C, pp. 136-148

To date, most of the existing wind farms have been built on-land but during the last few years many countries have also invested in offshore applications. The shift towards offshore wind project developments has mainly been driven by European energy policies, especially in north-west countries....

Estimation of parameters of the Makeham distribution using the least squares method

Feng, Xinlong; He, Guoliang; Abdurishit - In: Mathematics and Computers in Simulation (MATCOM) 77 (2008) 1, pp. 34-44

The Makeham distribution has been used to describe human mortality and establish actuarial tables. The hazard function is defined by μ(t)=A+BCt, we use the least squares type estimation to estimate the parameters of Makeham distribution in this paper. Seven cases are considered, when A, B, C...

A complex discrete warm standby system with loss of units

Ruiz-Castro, Juan Eloy; Fernández-Villodre, Gemma - In: European Journal of Operational Research 218 (2012) 2, pp. 456-469

A redundant complex discrete system is modelled through phase type distributions. The system is composed of a finite number of units, one online and the others in a warm standby arrangement. The units may undergo internal wear and/or accidental external failures. The latter may be repairable or...

Probability chains: A general linearization technique for modeling reliability in facility location and related problems

O’Hanley, Jesse R.; Scaparra, M. Paola; García, Sergio - In: European Journal of Operational Research 230 (2013) 1, pp. 63-75

In this paper, we propose an efficient technique for linearizing facility location problems with site-dependent failure probabilities, focusing on the unreliable p-median problem. Our approach is based on the use of a specialized flow network, which we refer to as a probability chain, to...
