The business processes of any modern organization as a result of the interaction between participants of the forest waste processing cluster are closely related to information technology. The article deals with the project of introducing an information system, which turns out to be a serious transformation, affecting various areas of the enterprise, ranging from the reflection of core activities, ending with regulations for user support. The information system implementation project is divided into the main stages, during which the requirements for the system are formed, changing business processes are considered, a model of the future system is created and put into pilot operation.

A model of the distribution of laminar temperature and dynamic boundary layers is considered. An integral relation is derived for the energy equation of the temperature spatial boundary layer, that allows integration over the surface of any shape, which is necessary for determining the thickness of the energy loss., The expressions for the thickness of the energy loss of the temperature spatial boundary layer are defined for the laminar flow. The expressions for the thickness of the energy loss are necessary to determine the local heat transfer coefficients for the characteristic cases of flow, taking into account heat transfer. Analytically, expressions are obtained for determining the local heat transfer coefficient in the form of the Stanton criterion for the rotational flow according to the law of a solid and the rotational flow of a free vortex. Local heat transfer coefficients are determined for laminar rotational flows.

Abrasive flow machining (abrasive flow machining (AFM)) is increasingly used worldwide. It is used for finishing and removing surface stresses in parts, the finishing machining of which using traditional methods is difficult. By now there are a large number of publications on this topic. A special interest are the articles in which previous works on various aspects of this technology are systematized. Due to a number of reasons, there are no publications from the scientific periodicals of Russia. This article presents a review of the works of Russian researchers in modelling the machining process by abrasive flow. They are aimed at modelling the rheological characteristics of the medium and contact interactions in processing. Particular attention is paid to the machining of an abrasive flow with an aligning device, as well as parts from powder molybdenum. The purpose of this article is to acquaint the wide range of readers with the works of Russian studies in the treatment of the abrasive flow of high viscosity medium.
