In this paper, we present a statistical criterion for accepting/rejecting the pairwise reciprocal comparison matrices in the analytic hierarchy process. We have studied the consistency in random matrices of different sizes. We do not agree with the traditional criterion of accepting matrices due to their inflexibility and because it is too restrictive when the size of the matrix increases. Our ...

Geographical information systems (GIS) provide forest managers with tools to use in planning forest operations by allowing them to visualize and integrate data into the planning decisions. As the forest planning process becomes increasingly complicated, there is a need to assist forest planners with operative tools. The combined use of GIS and multi-criteria decision methods (MCDM) allows fores...

An analytical solution of the equation describing diffusion of intrinsic point defects in semiconductor crystals has been obtained for a one-dimensional finite-length domain with the Robin-type boundary conditions. The distributions of point defects for different migration lengths of defects have been calculated. The exact analytical solution was used to verify the approximate numerical solutio...
