this paper develops positive mathematical programming (pmp) model to determine the optimum cropping pattern and water demand function in six regions of lower part lands of shirindarre dam in north khorasan province of iran and then estimates the expected pay for water in each region. the quantity of water supplied from such different water resources as dams, wells, and rivers in different scena...
one of the main principles of the passive defense is the principle of site selection. in this paper, we propose a multiple objective nonlinear programming model that considers the principle of the site selection in terms of two qualitative and quantitative aspects. the purpose of the proposed model is selection of the place of key production facilities of a system in which not only it observes ...
preventive maintenance scheduling is to perform a series of tasks that prevents or minimizes production breakdowns and improves the reliability. mathematical models have been developed to solve the preventive maintenance scheduling problem. there are several limitations in the prior work in this area of research. craft combinations are assumed to be given. the craft combination problem concerns...
