A Multiobjective Optimisation Model for Groundwater Remediation Design at Petroleum Contaminated Sites

Yang, Q.; He, L.; Lu, H. - In: Water Resources Management 27 (2013) 7, pp. 2411-2427

This study proposes a fuzzy multi-objective model for groundwater remediation in petroleum-contaminated aquifers. The optimisation system is designed based on the PAT technology, and includes two objectives (i.e. total pumping rate and average post-remedial contaminant concentration). The...

Inferring Efficient Weights from Pairwise Comparison Matrices

Blanquero, R.; Carrizosa, E.; Conde, E. - In: Mathematical Methods of Operations Research 64 (2006) 2, pp. 271-284

Several multi-criteria-decision-making methodologies assume the existence of weights associated with the different criteria, reflecting their relative importance.One of the most popular ways to infer such weights is the analytic hierarchy process, which constructs first a matrix of pairwise...

A multi-objective shortest path problem

Wakuta, Kazuyoshi - In: Mathematical Methods of Operations Research 54 (2001) 3, pp. 445-454

We study a multi-objective shortest path problem. We formulate a multi-objective Markov decision process model for the problem and solve it by the policy improvement procedure. We first show by counter-examples the differences between the multi-objective shortest path problem and the...

Optimal power flow solutions through multi-objective programming

Salgado, R.S.; Rangel, E.L. - In: Energy 42 (2012) 1, pp. 35-45

Despite the progress achieved in the development of optimal power flow (OPF) programs, most of the solution techniques reported in the literature suffer from the difficulty of dealing with objective functions of different natures at the same time. However, the need for alternative power network...
