AbstractNext-generation enterprise management systems are beginning to be developed based on the Systems of Engagement (SOE) model. We visualize an SOE as a set of entities. Each entity is modeled by a single parent document with dynamic embedded links (i.e., child documents) that contain multi-modal information about the entity from various networks. Since entities in an SOE are generally queried using keywords, our goal is to efficiently retrieve the top-k entities related to a given keyword-based query by considering the relevance scores of both their parent and child documents. Furthermore, we extend the afore-mentioned problem to incorporate the case where the entities are geo-tagged. The main contributions of this work are three-fold. First, it proposes an efficient bitmap-based approach for quickly identifying the candidate set of entities, whose parent documents contain all queried keywords. A variant of this approach is also proposed to reduce memory consumption by exploiting skews in keyword popularity. Second, it proposes the two-tier HI-tree index, which uses both hashing and inverted indexes, for efficient document relevance score lookups. Third, it proposes an R-tree-based approach to extend the afore-mentioned approaches for the case where the entities are geo-tagged. Fourth, it performs comprehensive experiments with both real and synthetic datasets to demonstrate that our proposed schemes are indeed effective in providing good top-k result recall performance within acceptable query response times.

The article analyzes the social and labor processes occurring in the hospitality industry. The general algorithm of transition to the new personnel management system of innovative type for the company in the field of hospitality is investigated. Regularities of innovative development of personnel management systems at a typical enterprise in the field of hospitality and their characteristics are revealed. The following steps for the transition to a system of "human resource management" are proposed: the formation of the principles of social partnership; creation of differentiated subsystems that are focused on individual social groups; decentralization of personnel management and transformation of the relevant specialized service into a consulting and methodological one with some integration into other enterprise management systems; development of forms of relations that allow investing in staff development; development of motivational bases of management, formation of collectives focused on creativity and self-organization.

AbstractThis work presents a scalable data access layer, called PyEHR, intended for building data management systems for secondary use of structured heterogeneous biomedical and clinical data. PyEHR adopts openEHR formalisms to guarantee the decoupling of data descriptions from implementation details and exploits structures indexing to speed up searches. The persistence is guarantee by a driver layer with a common driver interface. Presently, are implemented the interfaces with two NoSQL DBMS: MongoDB and Elasticsearch. The scalability of PyEHR has been evaluated experimentally through two types of tests, namely constant load and constant number of records, with queries of increasing complexity on a two synthetic datasets of ten millions records each, containing very complex openEHR archetype structures, distributed on up to ten working nodes.

Management system's specialization is the main principle of its formation. If you want to define the specialization's influence on others dimensions of this system, it is necessary to express it quantitatively. At this moment there are two types of management systems in building enterprises—functional and divisional. By this reason all system specialization subscription can find all these types which are expressed quantitatively. In this connection management specialization generalization will be of these parts geometrical mean number.

The prospects and directions of improvement of the methodology for strategic enterprise management have been highlighted. The subject of the research is theoretical and methodological aspects of creating a strategic enterprise management system based on the concept of a Balanced Scorecard (BSC). It has been revealed that in the context of changing the concept of the enterprise strategic development toward the growth of its intellectual capital as the main factor of competitiveness, the evolution of the enterprise management and planning system from strategic enterprise management to balanced enterprise management is taking place. The balanced scorecard has been defined as the basic concept of balanced enterprise management. The purpose of the study is to outline the prospects and directions for improving the methodology of strategic enterprise management under the conditions of its evolution into balanced enterprise management. Results. On the basis of a mathematical representation of the sphere of strategic responsibility (SSR) of the enterprise as an organizational and infrastructural environment for balanced enterprise management, it has been proved that the interaction of the SSR content components results in a synergistic effect of its expansion. This, in turn, determines the necessity and possibility of distributing the company’s SSR beyond its management and involving the initiative owners in the process of balanced enterprise management. Accordingly, the prospects for improvement of the strategic enterprise management methodology have been defined as an integration of strategic management systems, approaches, methods and the BSC with non-traditional eventological methods combined with the analytic hierarchy process. It has been proved that, from the standpoint of the eventology, subjective observations and the mathematical apparatus of the theory of random events allow identification of general statistical regularities of the probabilistic set distribution in various, including management, systems. From the standpoint of a balanced approach, the need for enriching the methodology of the BSC as a system of balanced enterprise management, using the eventological analysis, is being boosted by the need to take into account the growing number of random, multi-directional and seemingly unrelated factors in the management process. Methodology. The following research methods were used in the study: the expert assessment method, factor analysis – for the formation of the management panel of the BSC; the eventological scoring and analytic hierarchy process – for balancing and structuring key performance indicators (KPI), economic and mathematical methods – to analyse the SSRs of the enterprise as an organizational and infrastructural environment for balanced enterprise management; a critical analysis – to compare alternative approaches to the formation of the BSC. Value/originality. To achieve the purpose of the study, the BSC methodology has been presented as a system of balanced enterprise management. A methodical approach to balancing and structuring KPIs, using the results of eventological analysis and analytic hierarchy process, has been proposed. Its practical implications include the possibility of reaching the target balance of indicators taking into account weighing coefficients of the main indicator selection criteria, the possibility to determine the whole system balance index as the average of the balance indices of each of the indicators that characterize the enterprise performance. The ways of implementing the methods of e-scoring and analytic hierarchy process for the assessment and correction of the enterprise’s strategy have been studied. Integration of e-scoring with the strategic enterprise management method and the BSC methodology provides an effective vertical communication as the basic principle of balanced enterprise management, which extends the scope of strategic responsibility to subordinate initiative owners.

The development and implementation of specific technical procedures tend to be emphasized as key measures required to ensure the integrity of pipeline systems. These activities are clearly of vital importance. However, the integration of these activities and associated integrity programs with the overall management of the business also plays an important role in guaranteeing success of the programs. This paper describes a typical pipeline integrity management system, its objectives, and its links to other enterprise management systems. The paper also outlines simple methods that can be used to evaluate any given integrity management system’s components with a view to evaluating the programs effectiveness and driving continual improvement. These methods involve the identification of gaps with respect to specified benchmarks, and the design and implementation of risk-based programs to close the gaps. The benefits claimed include: • A comprehensive and holistic approach to pipeline integrity management aligned with company goals and objectives. • Engagement of company-wide technical expertise. • Buy-in and validation by all levels of company management. • Promotion of a company culture that encourages sustainable development of integrity management programs.
