Well Field Management Using Multi-Objective Optimization

Hansen, Annette; Franssen, Harrie-Jan Hendricks; … - In: Water Resources Management 27 (2013) 3, pp. 629-648

Efficient management of groundwater resources is important because groundwater availability is limited and, locally, groundwater quality has been impaired because of contamination. Here we present a multi-objective optimization framework for improving the management of a water works that...

A Set of New Benchmark Optimization Problems for Water Resources Management

Karpouzos, Dimitrios; Katsifarakis, Konstantinos - In: Water Resources Management 27 (2013) 9, pp. 3333-3348

In this paper, we introduce four new benchmark problems, which are based on rather common optimization issues of water resources management. These problems have the following features: a) adjustable difficulty, to cover a wide range of common engineering problems b) physical background familiar...

Chaotic Evolutionary Algorithms for Multi-Reservoir Optimization

Arunkumar, R.; Jothiprakash, V. - In: Water Resources Management 27 (2013) 15, pp. 5207-5222

, evolutionary algorithms have been successfully applied for optimizing the multi-reservoir system operations. The evolutionary … optimization algorithms start its search from a randomly generated initial population to attain the global optimal solution …. However, simple evolutionary algorithms are slower in convergence and also results in sub-optimal solutions for complex …

A competitive magnet-based genetic algorithm for solving the resource-constrained project scheduling problem

Zamani, Reza - In: European Journal of Operational Research 229 (2013) 2, pp. 552-559

This paper presents a genetic algorithm for solving the resource-constrained project scheduling problem. The innovative component of the algorithm is the use of a magnet-based crossover operator that can preserve up to two contiguous parts from the receiver and one contiguous part from the...

Monitoring delivery chains using multivariate control charts

Faraz, Alireza; Heuchenne, Cédric; Saniga, Erwin; … - In: European Journal of Operational Research 228 (2013) 1, pp. 282-289

Delivery chains are concerned with the delivery of goods and services to customers within a specific time interval; this time constraint is added to the usual consumer demand for product or service quality. In this context, we address the idea of using process control tools to monitor this key...

Bayesian inference in nonlinear mixed-effects models using normal independent distributions

Lachos, Victor H.; Castro, Luis M.; Dey, Dipak K. - In: Computational Statistics & Data Analysis 64 (2013) C, pp. 237-252

Nonlinear mixed-effects (NLME) models are popular in many longitudinal studies, including those on human immunodeficiency virus (HIV) viral dynamics, pharmacokinetic analysis, and studies of growth and decay analysis. Generally, the normality of the random effects is a common assumption in NLME...
