The theoretical model and numerical method are proposed for research of thermal and mechanical actions of radiation fluxes of various physical natures on thin-walled multilayered aircraft constructions. The finite — difference scheme of the second order of accuracy for temporary and to spatial variables is used for numerical integration of the movement equations of orthotropic shell having variable thickness and uneven heating. Results of calculations obtained by the author in the developed software system are given.

This article discusses the possibility of using MS Excel to solve linear programming problems. The problem is formulated as a problem of business entity value management. This reduces the problem to the maximization of the total cash flow of the company by providing control inputs to the partial cash flows which determine the need and possibility of using this tool.

The article considers the numerical solution of multicriteria optimization problem of capital structure, which was formulated in the previously published article authors. Model of the problem is modified to suit different scenarios of financial and economic activities of the organization in the forecast period. On the basis of the data of real financial statements algorithm its solutions implemented in the Maple using the guaranteed result in the normalization criteria.
