Alternate approximation of concave cost functions for process design and supply chain optimization problems
(Elsevier, 2014-01)
This short note presents an alternate approximation of concave cost functions used to reflect economies of scale in process design and supply chain optimization problems. To approximate the original concave function, we ...
ASSESSMENT OF FOREST DELIMBER IN FUNCTION OF TIME WOOD STORAGE IN FIELD
(Centro Pesquisas Florestais, Ufsm, 2018-07-01)
With the innovations of mechanized harvesting in Brazil, become necessary studies to obtain real data on the new machines that are emerging in the market. The study aimed to the technical evaluation and cost a forest ...
Thermoeconomic analysis of hydrogen incorporation in a biodiesel plant
(2017-02-25)
The paper develops a methodology that uses the thermoeconomic functional diagram applied for allocating cost of products obtained by the plant and afterwards demonstrates how it is possible to calculate the marginal cost ...
Ecological efficiency and thermoeconomic analysis of a cogeneration system at a hospital
(Pergamon-Elsevier B.V. Ltd, 2012-06-01)
This work aims with an approach for cogeneration plants evaluation based on thermoeconomic functional diagram analysis. The second law of thermodynamics is used to develop a methodology to analyse cogeneration systems, ...
Pricing with markups in industries with increasing marginal costs
(Springer, 2014)
We study a game that models a market in which heterogeneous producers
of perfect substitutes make pricing decisions in a first stage, followed by consumers
that select a producer that sells at lowest price. As opposed ...
Minimization of discontinuous cost functions by smoothing
(Kluwer Academic PublDordrechtHolanda, 2002)
Thermoeconomic analysis method for optimization of combined heat and power systems - part II
(Elsevier B.V., 2004-01-01)
In this paper, a thermoeconomic functional analysis method based on the Second Law of Thermodynamics and applied to analyze four cogeneration systems is presented. The objective of the developed technique is to minimize ...
Regularized quadratic cost function for oriented fringe-pattern filtering
(OSA Publishing, 2009-06-01)
We use the regularization theory in a Bayesian framework to derive a quadratic cost function for denoising
fringe patterns. As prior constraints for the regularization problem, we propose a Markov random field
model that ...
Development of a methodology for cost determination of wastewater treatment based on functional diagram
(Pergamon-Elsevier B.V. Ltd, 2009-07-01)
This work describes a methodology developed for determination of costs associated to products generated in a small wastewater treatment station for sanitary wastewater from a university campus. This methodology begins with ...
