Abstract

The accuracy of the calculation and optimization of the objective function and its parameters when solving applied engineering problems depends on the accuracy of the formulation of the main optimization problem, calculation and applied optimization problems, as well as the accuracy of computational methods for their implementation. An increase in the considered features of applied optimization problems will complicate the setting and methods of implementing boundary value problems. Thus, for the implementation of modernized boundary value problems, it will be necessary to apply several computational methods that will create a computational structure. The main condition for constructing a physically based boundary value problem is to find and justify the conditions for the existence of a unique solution. To increase the efficiency of the use of methods of calculation and optimization of technical parameters, it is necessary to increase the number of considered features of calculation and applied optimization mathematical models for heat and mass transfer in technical systems. Along with the construction of boundary value problems, it is important to define and justify the conditions for the existence of a single solution. The research article deals with some aspects of solving applied problems of heat and mass transfer in technical systems. Nonlocal boundary value problems for inhomogeneous and homogeneous pseudodifferential equations in partial derivatives with integral boundary conditions are considered, methods of solving a nonlocal inhomogeneous boundary value problem are proposed, and the correctness conditions of this problem in the class of infinitely differentiable generalized functions of power growth are defined and proven. Proved conditions for the existence of a correct problem for pseudo-differential equations with an integral boundary condition. The research of this article should be applied for controlling possible risks when solving applied problems in technical systems, biotechnology and veterinary medicine.
计算方法在解决复杂系统中热交换和质量交换应用问题中的应用
在解决应用工程问题时,目标函数及其参数的计算和优化的准确性取决于主要优化问题、计算和应用优化问题的表述的准确性,以及实现这些问题的计算方法的准确性。应用优化问题所考虑的特征的增加将使边值问题的设置和实现方法复杂化。因此,为了实现现代化的边值问题,有必要应用几种计算方法来创建计算结构。构造基于物理的边值问题的主要条件是找到并证明唯一解存在的条件。为了提高技术参数计算和优化方法的使用效率,有必要增加技术系统传热传质计算的考虑特征和应用优化数学模型的数量。在构造边值问题的同时,重要的是定义和证明单解存在的条件。本文研究了解决技术系统中传热传质应用问题的几个方面。研究了具有积分边界条件的偏导数的非齐次和非齐次伪微分方程的非局部边值问题,给出了求解非局部非齐次边值问题的方法,定义并证明了该问题在幂增长无穷可微广义函数类中的正确性条件。证明了具有积分边界条件的伪微分方程的一个正确问题的存在性条件。本文的研究可用于解决技术系统、生物技术和兽医学等领域的应用问题时可能出现的风险控制。
