Enterprise architecture (EA) is a collection of artifacts describing various aspects of an organization from an integrated business and IT perspective. EA practice is an organizational activity that implies using EA artifacts for facilitating decision-making and improving business and IT alignment. EA practice involves numerous participants ranging from C-level executives to IT project teams and effective engagement between these stakeholders and architects is critically important for success. However, the notion of engagement has received insufficient attention in the EA literature and the problem of establishing engagement has not been examined in detail. Based on a single in-depth case study, this paper explores the problem of achieving engagement in EA practice. Using the grounded theory method, we identify 16 direct and two indirect inhibitors of engagement and unify them into a holistic conceptual model. The model explains how the inhibitors of engagement undermine the ability to realize value from practicing EA.

Architecture of the compressor equipment monitoring and control cyber-physical system (CPS) based on the InfluxData IoT platform is proposed. CPS consists of three subsystems: a subsystem of a physical object, a digital twin and an interface. As a technical implementation of the IoT controller, a measuring and control module based on a data acquisition, data transfer and control device - VIDA350, connected to the Telegraf data collection agent of the platform using the MQTT protocol, is proposed. The basic methods of processing raw data from energy meters and sensors of technological parameters, implemented in blocks of on-line and off-line calculations are given. The organization of the digital twin of the compressor using the database of time series InfluxDB and the relational database MSSQL, storing information about changes in the technological parameters of equipment over time, energy efficiency indicators, statistics on accidents and operating time, equipment models, etc., is proposed. Grafana system and FreeCAD is used for visualization of equipment in 3D. The use of CPS can increase the efficiency of operation of compressors due to the timely detection of air leaks, minimizing idling, minimizing peak consumption, optimizing process parameters and settings both of the compressors and consumers.
Subject: smart house maintenance requires taking into account a number of factors - resource conservation, mitigating working expenditures, safety enhancement, ensuring comfort of leisure and operation. Automation of such engineering systems networks as illumination, climate control, security and communication, may be achieved through utilization of contemporary technologies (e.g. IoT – Internet of Things). However, storing and processing the overwhelmingly massive corpora of data produced by the aforementioned systems poses a significant challenge. It is necessary to rationally manage the available big data during the stage of information modelling, due to the fact, that a building’s lifespan outlives most iterations of safety, comfort, and maintenance standards substantially.
Materials and methods: since smart houses may be classified as human-machine systems, the cybernetic approach will be considered as the base method of information system design and discovery. Instrumental methods are represented by set-theoretical modelling, automata theory and architectural principles of information management systems’ organization.
Results: an agile architecture of information system for smart house hardware management has been synthesized. The architecture encompasses several levels: client level, application level and data level; as well as three layers: presentation level, actuating devices layer and analytics layer. As proposed, the problem of growing volumes of information process by realtime message controller is attended by employment of sensors with configurable thresholds and actuating mechanisms, which implement control logic based on discrete automaton (namely, logical algorithm schemes). Multicircuit control system is suggested to be additionally enhanced with datamining module, DBMS, datamarts, and OLAP cube, which are jointly capable of processing large amount of data produced by hardware subsystems.
Conclusions: an information system for smart house hardware management, once built according to the proposed architecture, will enhance the quality of decision-making process, decrease operational costs of the smart house, due to the datamining-enabled control circuit. Suggested solution is recommended to be employed for the management of buildings and constructions, that utilize means of automation and IoT.
This paper considers a dynamic ventilation system of the underground mining. The research is relevant from the point of view of safety and energy saving of mining operations, since the process of ventilation of underground mining companies consumes from 30 to 50% of all company electricity. Existing methods of ventilation control often do not ensure rational energy consumption, as they do not take into account the dynamics of air distribution and changes in environmental parameters. The proposed method includes basic algorithms for calculating the interrelationship of physical parameters of general natural draught between the trunks. The method includes: calculation of the draught’s power; calculation of productivity and the choice of the required mode of operation for the main fan unit (MFU) considering the inertia of the ventilation system; dynamic calculation of the control signal on the fan unit taking into account the impact of the general natural draught. The method is focused on the implementation of the TICK stack used to create IoT applications as part of the Cyber-Physical System (CPS) for ventilation based on the InfluxData platform. The proposed CPS architecture consists of four subsystems: physical object subsystem, IoT network and computing infrastructure - ICT infrastructure, digital twin, user interface. CPS architecture provides processing of data from energy meters, controllers and air environment parameters, implemented in on-line and off-line calculation units
The theory of the information society considers the information and media as the primary source of social development. At present the use of the latest achievements in the field of Information Communication Technologies (ICT) in economy and management, including the contemporary methods and tools of computer modelling is one of the key factors in improving organizational performance and increasing its competitiveness. This paper focuses on the various modelling methods and techniques that are employed in the design of management information systems (MIS) architecture. Its goal is to evaluate the role of modelling for spatiotemporal analysis of marketing information system in the context of spatial economics paradigm development. Interdisciplinarity of spatial marketing researches consists not only in expanding the subject of research (joint study of the spaces of different types), but in the synthesis of notions, concepts and methodologies of the social, humanitarian, sociological and engineering sciences, modelling and prediction of interaction and mutual influence of different kinds spaces, a generalization of the theoretical results and creating of the interdisciplinary databases.The paper also considers the main features of soft computing (neural network and fuzzy logic) and discusses its implementation for design of sustainable adaptive architecture of spatial information system. It does so from a research base that draws from theoretical underpinnings as well as international and domestic industry practices.
Value co-creation is a new notion in contemporary business practice, which is now also becoming one of the key marketing concepts. The success of the value co-creation strategy is based on the DART (dialogue, access, risk-benefits and transparency) concept which is emerging as the basis for interaction between the consumer and the firm. Still, the lack of a formalized approach towards the representation of the DART mechanism remains an issue. Thus, the purpose of the present paper is to describe a formal approach based on DEMO methodology tools as an attempt aimed at value co-creation process modelling.
