A multi-objective mathematical model for the industrial hazardous waste location-routing problem
(Elsevier Science Bv, 2013)
Industrial hazardous waste management involves the collection transportation treatment recycling and disposal of industrial hazardous materials that pose risk to their surroundings. In this paper a new multiobjective ...
Multi-objective Fuel Supply for Coal-fired Power Plants Under Emission Transportation and Operational Constraints
(Taylor & Francis Inc, 2013)
Coal-fired power plants need to decrease their generation cost in deregulated power markets so as to be selected dispatched and compete with other cheaper resources. On the other hand coal prices have risen significantly ...
Agent-based Optimization to Estimate Nash Equilibrium in Power Markets
(Taylor & Francis Inc, 2013)
In most deregulated power markets firms bid daily into a day-ahead power market. The auction mechanism supply and demand determine the equilibrium at each hour. In this environment firms aim to maximize their revenues by ...
Managing Fuel Coal Supply Chains With Multiple Objectives and Multimode Transportation
(AMER SOC ENGINEERING MANAGEMENT, 2013)
Power companies require sophisticated tools to manage fuel-coal supply chains which include multiple suppliers coal contracts and multimode transportation routes. In this article a multi-objective model which is integrated ...
Inventory planning and coordination in disaster relief efforts
(Elsevier Science Bv, 2013)
This research proposes a stochastic programming model to determine how supplies should be positioned and distributed among a network of cooperative warehouses. The model incorporates constraints that enforce equity in ...
Generalized Einstein tensor for a Weyl manifold and its applications
(Springer Heidelberg, 2013)
It is well known that the Einstein tensor G for a Riemannian manifold defined by R (alpha) (beta) = g (beta gamma) R (gamma I +/-) where R (gamma I +/-) and R are respectively the Ricci tensor and the scalar curvature of ...
Nutrient Dynamics in Flooded Wetlands. I: Model Development
(ASCE-AMER SOC CIVIL ENGINEERS, 2013)
Wetlands are rich ecosystems recognized for ameliorating floods improving water quality and providing other ecosystem benefits. This part of a two-paper series presents a relatively detailed process-based model for nitrogen ...
Nutrient Dynamics in Flooded Wetlands. II: Model Application
(ASCE-AMER SOC CIVIL ENGINEERS, 2013)
In this paper the authors applied and evaluated the wetland nutrient model that was described in Paper I. Hydrologic and water quality data from a small restored wetland located on Kent Island Maryland which is part of the ...
Master problem approximations in Dantzig-Wolfe decomposition of variational inequality problems with applications to two energy market models
(Pergamon-Elsevier Science Ltd, 2013)
In this paper a modification to Dantzig-Wolfe (DW) decomposition algorithm for variational inequality (VI) problems is considered to alleviate the computational burden and to facilitate model management and maintenance. ...
'Level grading' a new graded algebra structure on differential polynomials: application to the classification of scalar evolution equations
(IOP Publishing Ltd, 2013)
We define a new grading which we call the 'level grading' on the algebra of polynomials generated by the derivatives u(k+i) over the ring K-(k) of C-infinity functions of x t u u(1) ... u(k) where . This grading has the ...
