The operational economics of compressed air energy storage systems under uncertainty
(Pergamon-Elsevier Science Ltd, 2013)
A Compressed Air Energy Storage System is a means of storing energy which can then be used when the demand for energy increases. In this system air is compressed in a cavern when power prices are low and this air is used ...
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 ...
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 ...
Scheduling a log transport system using simulated annealing
(Elsevier Science, 2014)
The log truck scheduling problem under capacity constraints and time window constraints is an NP-hard problem that involves the design of best possible routes for a set of trucks serving multiple loggers and mills. The ...
Supplier Selection for Framework Agreements in Humanitarian Relief
(Wiley-Blackwell, 2014)
In this study we consider the supplier selection problem of a relief organization that wants to establish framework agreements (FAs) with a number of suppliers to ensure quick and cost-effective procurement of relief ...
An evolutionary approach for tuning parametric Esau and Williams heuristics
(Palgrave Macmillan Ltd., 2012)
Owing to its inherent difficulty many heuristic solution methods have been proposed for the capacitated minimum spanning tree problem. On the basis of recent developments it is clear that the best metaheuristic implementations ...
