In this case, the optimal placement of heat sources on the area should be such that the total power of the consumed heat sources is minimal, so that the temperature is within the specified limits. By approximating the original problem, we obtain a difference equation. The construction of implicit difference schemes for the heat equation is given. From the difference equation it is reduced to a system of linear algebraic equations. The problem was solved using the M-method. In the parallelepiped, a new approach is proposed based on the numerical solution of the non-stationary problem of the optimal choice of the location of heat sources. Algorithms and software were developed for the numerical solution of the problem. A brief description of the software is provided. The results of a computational experiment are visualized.</p> ER -
