Дано определение монотонности таких разностных схем, связанное со свойством положительности разностного решения. На основе этого определения построены монотонные разностные схемы для модели Шнэкенберг с граничными условиями Дирихле и Неймана. Эта модель представляет собой полунелинейную реакционно-диффузную систему и играет важную роль при математическом моделировании в областях физической химии и биологии. При построении монотонной разностной схемы для указанной модели с граничным условием Неймана основная идея состоит в том, чтобы использовать полуцелые узлы в граничных точках задания краевых условий второго рода. Представлены результаты вычислительных экспериментов, подтверждающих эффективность предложенных методов. численное решение получено без нефизических осцилляций.</p></abstract><trans-abstract xml:lang="en"><p>In this article the canonical form of the vector-difference schemes is constructed. The definition of the monotonicity of difference schemes is given. This definition is related to the positivity property of the difference solution. Based on this definition, the monotone difference schemes for the Schnakenberg model with the Dirichlet and Neumann boundaryconditions are constructed. This model is a semi-nonlinear reaction-diffusion system, and it plays an important role in mathematical modeling in the fields of physical chemistry and biology. In constructing a monotone difference scheme for this model with the Neumann boundary condition, the idea of half-integral nodes at the boundary points under the secondkind boundary conditions is used. The results of numerical experiments have confirmed the effectiveness of the suggested methods. the numerical solution without nonphysical oscillation is obtained.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>модель Шнэкенберг</kwd><kwd>монотонная разностная схема</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Schnackenberg model</kwd><kwd>monotone difference scheme</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Матус, П.
