A barrier method for dynamic Leontief-type linear programs

Article Abstract:

The projected Newton barrier method is more effective in solving large-scale dynamic Leontief-type linear programs than the sparse simplex method. A special structure of the constraints matrix is used to reduce the matrix of the normal equation for the least-squares problem to a banded matrix in this barrier method. A comparative study of these two approaches shows the former to be faster than the simplex method for such types of linear programs.

Carbon sequestration and land management under uncertainty

Article Abstract:

Issues relating to the role of land-use change and forestry in easing the problem of global warming are investigated. The study uses a possibilistic linear programming model of agricultural and forest land management with the aim of maximising the cumulative net discounted returns.

Bankruptcy prediction using a data envelopment analysis

Article Abstract:

The classification performance of a linear programming (LP) model, a data envelopment (DEA) model and a rule induction (C5.0) model are compared. Results indicate that the DEA model performs better than the other models in terms of accuracy and employment.
