The purpose of this article is to find ways to implement an effective strategy for building and managing mobile robotic platforms in Warehousing, as a key tool of Lean Production. To achieve this goal, it is necessary to solve the following tasks: to analyze the management of supply chains in Smart Manufacturing, within Industry 4.0 and its impact on achieving the goals of Lean Production; to study the evolution of technologies used in Warehousing in the dynamics of the Industrial Revolution; to analyze the evolution of Warehouse Management Systems (WMS) as one of the most important components on the basis of which the requirements for automation of Warehousing automation in Smart Manufacturing with group management of mobile robotic platforms are implemented and achieved; to compare the impact of the technologies used by Warehousing 4.0 and Warehouse Management Systems on the key indicators of Lean Production. Results: One of the promising ways to achieve the effectiveness of the implementation of Lean Production tools in WMS systems is the use of Collaborative Robot System technology, which makes it possible to ensure a high density of product storage in Warehousing. However, modern mobile robotic platforms have their limitations both in the methods of loading and unloading products, and in the design. Therefore, the authors see the task in improving the design of mobile robotic platforms, which will develop a new intelligent group method of loading and unloading products, increasing the storage density for a variety of goods. Conclusions: The paper compares the impact of Warehousing 4.0 and Warehouse Management Systems on key Lean Production tools, which shows how the introduction of new group management technologies for robotic platforms in Warehousing 4.0 and Warehouse Management Systems (WMS) affects the effectiveness of Lean Production tools such as Heijunka, Just-in-time, 5S. This suggests that the introduction of new models and methods of managing complex warehouses with high density and chaotic storage of products, through the use of mobile robotic autonomous systems, will significantly optimize the process of supply chain management in Smart Manufacturing.

The results of the work are procedures and schemes of application of cryptomicrops of asymmetric authentication to ensure the protection of Internet of Things. Analysis of the functioning of the presented schemes allowed to draw the following conclusions. The proposed structural and functional schemes for the implementation of procedures for asymmetric authentication of Internet of Things using cryptographic chips give the user an easy opportunity to implement cryptography without expertise in this field. These chips use the ECDSA digital signature computing and verification hardware with elliptical curve advantages, as a proven and reliable authentication algorithm, and the ECDH symmetric encryption session key generation unit. The provided schemes and procedures support three components of information security, namely: confidentiality, integrity and authenticity of data. Examples of potential applications of the provided schemes and procedures can be implemented using any asymmetric authentication chip, but it is recommended that they be used to generate encryption session keys and where digital signatures are required to verify data and code for integrity and authenticity.

The subject of consideration is the task of identifying the states of an object based on the results of fuzzy measurements of a set of controlled parameters. The fuzziness of the initial data of the task further complicates it due to the resulting inequality of the controlled parameters. The aim of the study is to develop a method of identifying the states of a fuzzy object using a fuzzy mechanism of logical output taking into account possible differences in the level of information content of its controlled parameters. The method of obtaining the desired result is based on the modification of the known mathematical apparatus for building an expert system of artificial intelligence by solving two subtasks. The first is the development of a method for assessing the informativity of controlled parameters. The second is the development of a method for constructing a mechanism for logical inference of the relative state of an object based on the results of measuring controlled parameters, which provides identification. In the first problem, a method is proposed for estimating the informativity of parameters, free from the known disadvantages of the traditional Kulbak informativity measure. In implementing the method, it is assumed that the range of possible values for each parameter is divided into subbands in accordance with possible states of the object. For each of these states, the function of belonging to the fuzzy values  of the corresponding parameter is defined. At the same time, the correct problem of estimating the informativity of a parameter is solved for cases when this parameter is measured accurately or determined fuzzily by its belonging function. The fundamental difference between the proposed logical output mechanism and the traditional one is the refusal to use the production rule base, which ensures the practical independence of the computational procedure from the dimension of the task. To solve the main problem of identifying states, a non-productive approach is proposed, the computational complexity of which practically does not depend on the dimension of the problem (the product of the number of possible states Results.per the number of controlled parameters). The logic output mechanism generates a probability distribution of the system states. In this case, a set of functions of belonging of each parameter to the range of its possible values for each of the states of the object is used, as well as a set of functions of belonging to fuzzy measurement results of each parameter. Conclusions. Thus, a method of identifying the state of fuzzy objects with a fuzzy non-productive output mechanism is proposed, the complexity of which does not depend on the dimension of the task.

The subject of the report is the methodology of carrying out an examination of the application for the purpose of establishing the optimal acoustic minds in the prevalence of attribution. The goal is to improve the quality of all stages of acoustic examination, taking into account the premises for which there are special requirements for the quality of the transmitted content or for which there are features in the formation of the sound field. Such a sequence of stages requires the solution of several tasks: determining the conditions for conducting research, taking into account the specifics of the premises and content; selection of hardware and software complex for research; determination of informative criteria for assessing the acoustics of a room, taking into account all its features; processing and analysis of the results obtained. The application of this approach to the stages of acoustic examination was considered on the example of a conference room, for which there were requirements for high quality speech content, a sound reinforcement system was already used in the hall, and there were features in the formation of a sound field. The authors in the article describe the solutions to all the tasks for the investigated room. The results obtained made it possible to analyze the objective characteristics of the sound field and identify the reasons for the low quality of speech content transmission not only in the acoustic calculation, but when using the existing sound reinforcement systems (electroacoustic calculation). Conclusions. The proposed sequence of the stages of acoustic examination makes it possible to identify "problem" places in the formation of the sound field and / or to determine possible solutions even before the stages of checking existing architectural and construction solutions and the development of technical specifications for the construction of enclosing surfaces and measures to create optimal acoustic conditions.
