Information system for creating a generalized model of complex technical objects

Creation of complex technical objects (CTO, such as science-intensive engineering objects, which are characterized by the number of elements and connections equal to 106 and more) – a process containing long subprocesses, complex objects, models, and based on available standards and information technology (IT). It is known from practice that CTO models are created with the help of information systems - components of CALS and PLM-solutions. This process have the following shortcomings: models at different stages of creation of CTO are not completely interconnected; CTO modeling takes place using different components of IT CALS and PLM-solutions, which creates constant difficulties in data conversion and leads to partial or complete loss of model data; there is no automated communication with other CTO models. A generalized model of complex technical objects is proposed, which based on using the theoretical-multiple approach allows to establish an information connection between the models of the process of creating complex technical objects. The information system of creation of the generalized model of difficult technical objects that allowed automating process of processing and construction of models is developed; to supplement the technology of parallel PLM design and components of information technologies CALS and PLM-solutions for the task of creating models of complex technical objects.

FUZZY-MULTIPLE APPROACH TO RISK ASSESSMENT UNDER THE CONDITIONS OF MANAGEMENT DIGITALIZATION IN ENTERPRISE ACTIVITY

The success of the enterprise in the market depends on the level of its competitiveness, which, in turn, is determined by the level of competitive advantages of products developed and supplied to the market.Constant updating of the product range by modern enterprises allows them to extend the time of their effective life and ensure success in the long run. To do this, companies must constantly carry out innovative activity aimed at developing, implementing, and bringing new products to market to best meet consumer needs. However, companies must not only explore the main factors of success, but also the sources of risk that accompany the introduction of innovative products to market.The effectiveness of product innovation policy of the dairy industry is determined by the optimal combination of traditional and new products (new convenient packaging, new flavors, size, etc.). The article considers a fuzzy multiple approach to assessing the risk of bringing innovative products of the dairy industry to market.This approach is based on the «RWW» criteria for assessing the risk of bringing new products to market (Real, Win, Worth it), which is considered inthework of George S. Day. Based on the risk assessment criteria, a fuzzy-multiple model of risk assessment for bringing innovative products to market was built. As a result, an assessment for the risk of launching a novelty on the market was obtained for the three components o the RWW instrument and the integrated generalized one.The advantage of using the proposed method is the possibility of forming an aggregate risk indicator for the introduction of a new product on the market, which takes into account not only quantitative but also qualitative characteristics of the evaluation indicators.

Paleotsunami Evidence in the Bahía Inglesa Coast (Atacama, Chile) Based on a Multi-Approach Analysis

The Atacama coast is located in an area with a current high risk of tsunami, and the sedimentary deposits found in the Bahía Inglesa area, in the Morro sector, clearly indicate that this was also the case in the past. Thisinvestigation analyzes a paleotsunami sedimentary deposit consisting of a block field associated with three sand lobes oriented towards land on top of a marine terrace at an altitude of 70–75 m, which originated from a tsunamigenic event occurred between interglacial periods MIS 7 (ca. 210 ± 10 ky) and MIS5e (ca.125 ± 5 ky). The deposits have been studied using a multiple approach combining geomorphological, sedimentological, biological, and geochemical criteria. The first type of criteria clearly indicate that the energy required to move the blocks and form the sand lobes could only have been generated by a tsunami. Sedimentological criteria constitute direct evidences of a marine origin due to the presence of siliceous remains from diatom species and spicules from strictly marine sponges, while geochemical criteria, such as the stable isotope signature and chemical composition, constitute evidence of a marine intrusion.

Formalization of Life Cycle Stages of Geographic Information Products Creation at Research and Production Enterprises

Purpose of research. The purpose of this article is to formalize the processes of creating geographic information products (GIP), within its life cycle (LC), taking into account heterogeneous types of GIS resources of a research - production enterprise (RPE). A typical subsystem of AIS infrastructure of an enterprise is an object of this study. Methods. On the basis of an analysis of scientific sources and standards it was shown that changes in traditional approaches, principles, models are necessary in the creation of GIP. It is also necessary to change infrastructure and resources management of NPP. Presented in tabular form model is describing GIP life cycle taking into account the list of required resources and provisions. Features of LC GIP based on geoinformation technologies processes have been identified. The general approach in formalization of stages describing processes of GIP processing and operation of typical elements of GIS enterprise is described. A model of automated processing process (APP) of GIP is developed on the basis of system representations and theoretical-multiple approach. It is represented by the Cartesian product of vectors. The role and features of information support in the development of GIP are highlighted. Results. The analysis of GIP functioning features, as well as developed structural graphic and tabular presentation, made it possible to identify links between GIP features and stages content of their LCs. The results will allow clearer positioning of GIP elements and components presented for development and operation, especially in GIS NPP. The results will provide an opportunity to define the requirements for systems of this class adequately. Conclusion. The presented LC GIP models, taking into account the identified features of their construction and functioning, will allow, in the future, setting and solving modeling and management system tasks of this class.

Utilisation, Availability and Price Changes of Medicines and Protection Equipment for COVID-19 Among Selected Regions in India: Findings and Implications

Background: COVID-19 has already claimed a considerable number of lives worldwide. However, there are concerns with treatment recommendations given the extent of conflicting results with suggested treatments and misinformation, some of which has resulted in increased prices and shortages alongside increasing use and prices of personal protective equipment (PPE). This is a concern in countries such as India where there have been high patient co-payments and an appreciable number of families going into poverty when members become ill. However, balanced against pricing controls. Community pharmacists play a significant role in disease management in India, and this will remain. Consequently, there is a need to review prices and availability of pertinent medicines during the early stages of the COVID-19 pandemic in India to provide future direction.Objective: Assess current utilisation and price changes as well as shortages of pertinent medicines and equipment during the early stages of the pandemic.Our Approach: Multiple approach involving a review of treatments and ongoing activities across India to reduce the spread of the virus alongside questioning pharmacies in selected cities from early March to end May 2020.Our Activities: 111 pharmacies took part, giving a response rate of 80%. Encouragingly, no change in utilisation of antimalarial medicines in 45% of pharmacies despite endorsements and for antibiotics in 57.7% of pharmacies, helped by increasing need for a prescription for dispensing. In addition, increased purchasing of PPE (over 98%). No price increases were seen for antimalarials and antibiotics in 83.8 and 91.9% of pharmacies respectively although shortages were seen for antimalarials in 70.3% of pharmacies, lower for antibiotics (9.9% of pharmacies). However, price increases were typically seen for PPE (over 90% of stores) as well as for analgesics (over 50% of pharmacies). Shortages were also seen for PPE (88.3%).Conclusion: The pandemic has impacted on utilisation and prices of pertinent medicines and PPE in India but moderated by increased scrutiny. Key stakeholder groups can play a role with enhancing evidenced-based approaches and reducing inappropriate purchasing in the future.

Analysis of portable rock art from Foz do Medal (Northwest Iberia): Magdalenian images of horses and aurochs

Studies focusing on Palaeolithic portable rock art have a long tradition in Europe. Nevertheless, they tend to only focus over formal and stylistic criteria of the motifs, important as they provide chronologies for cave art. This article proposes a multiple approach to a sample of 25 engraved plaques of the Foz do Medal archaeological site, where horses and aurochs were depicted, in order to construct a preliminary model able to guide the future analysis of the whole collection composed of more than 1500 fragments. On the one hand, relevant archaeological data was collected and systematized into a database that can be subjected to statistical analysis, for which we develop different variables and their respective attributes. On the other hand, laboratory techniques of analysis and examination of materials were applied, valuing the motifs details, their potential surface treatment by fire or pigments ornamentation, as well as the identification of raw materials and their origins. In this article, we present the obtained results, which allow us to propose some hypotheses regarding the social importance of this specific kind of artefact, as well as its possible manipulations.
