Optimization of network planning by the novel hybrid algorithms of intelligent optimization techniques

Sadegheih, A. - In: Energy 34 (2009) 10, pp. 1539-1551

This paper proposes a new hybrid algorithm Meta-heuristic for the problem of network planning systems. The main goal of … genetic algorithm, simulated annealing and tabu search for the defined optimization tasks; to develop a hybrid optimization … algorithm which will produce improved iterations compared to those found by GA, SA, and TS algorithms. The performance of the …

Transshipment model-based MILP (mixed-integer linear programming) formulation for targeting and design of hybrid power systems

Chen, Cheng-Liang; Lai, Chieh-Ting; Lee, Jui-Yuan - In: Energy 65 (2014) C, pp. 550-559

A HPS (hybrid power system) includes various sources of RE (renewable electricity) such as wind, solar, and biomass, and is supplemented by the public grid should the total RE supply is deficit to total demand. Given the operational capability of the total RE supply and the time-dependent demand...

Modeling methods for GenCo bidding strategy optimization in the liberalized electricity spot market–A state-of-the-art review

Li, Gong; Shi, Jing; Qu, Xiuli - In: Energy 36 (2011) 8, pp. 4686-4700

The electricity market has since 1980s been gradually evolving from a monopoly market into a liberalized one for encouraging competition and improving efficiency. This brings the opportunity for generation companies (GenCos) to make more profits while embracing more risks of not being...

On the unboundedness of facility layout problems

Drezner, Zvi - In: Computational Statistics 72 (2010) 2, pp. 205-216

Facility layout problems involve the location of facilities in a planar arrangement such that facilities that are strongly connected to one another are close to each other and facilities that are not connected may be far from one another. Pairs of facilities that have a negative connection...

Sensitivity analysis for discrete optimal control problems

Marinković, Boban - In: Computational Statistics 63 (2006) 3, pp. 513-524

We present local sensitivity analysis for discrete optimal control problems with varying endpoints in the case when the customary regularity of boundary conditions can be violated. We study the behavior of the optimal solutions subject to parametric perturbations of the problem. Copyright...

Decoupling and prices: determinant of dairy farmers’ choices?

Lelyon, Baptiste; Chatellier, Vincent; Daniel, Karine - Département Sciences Sociales, Agriculture et … - 2011

In this paper, we discuss the cross-effects on the productive strategy of French dairy farms due to the decoupling and to price variation. A model based on mathematical programming has been developed to determine how dairy farmers might re-evaluate their systems to identify an optimal production...

Farming system modelling for agri-environmental policy design: the case of a spatially non-aggregated allocation of conservation measures

Bamière, Laure; Havlik, Petr; Jacquet, Florence; … - Département Sciences Sociales, Agriculture et … - 2011

This paper addresses the issue of designing policies for habitat conservation on agricultural land. The case under study requires a non-aggregated spatial distribution of the fields to be enrolled in an agri-environmental programme. A spatially explicit mathematical programming farm-based model,...

A Parsimonious Hydrological Model for a Data Scarce Dryland Region

Pande, Saket; Savenije, Hubert; Bastidas, Luis; Gosain, … - In: Water Resources Management 26 (2012) 4, pp. 909-926

Inapplicability of state of the art hydrological models due to scarce data motivates the need for a modeling approach that can be well constrained to available data and still model the dominant processes. Such an approach requires embedded model relationships to be simple and parsimonious in...

Aversion to health inequalities in healthcare prioritisation: A multicriteria optimisation perspective

Morton, Alec - In: Journal of Health Economics 36 (2014) C, pp. 164-173

In this paper we discuss the prioritisation of healthcare projects where there is a concern about health inequalities, but the decision maker is reluctant to make explicit quantitative value judgements and the data systems only allow the measurement of health at an aggregate level. Our analysis...

Evaluating the potential contribution of spatially differentiated payments to the efficiency of Agri-Environmental Measures: A resource allocation model for Emilia Romagna (Italy)

Vergamini, Daniele; Raggi, Meri; Viaggi, Davide - Associazione Italiana di Economia Agraria e Applicata - … - 2013

The European Agri-Environmental Measures (AEMs) have a relevant role in encouraging a sustainable resources use and developing environmentally-friendly farming practices. AEMs account for more than half of the rural development budget of the Common Agriculture Policy. However, despite their...
