Supporting the life cycle of household appliances during the operation stage

The last decade of the twentieth century was characterized by a rapid digitalization of all areas of activity from traditional research to the automation of production, trade, commerce, banking, and other activities. The CALS technology has become largely popular in the world, including Russia. Continuous Acquisition and Lifecycle Support (CALS) stands for the continuous information support of supplies and the life cycle of products, or the information support for product life cycle (IPS) The product life cycle comprises a set of processes performed from the identification of needs for specific products to the satisfaction of such needs and the scrapping of the products. The analysis of the household appliance service companies helped identify the key causes of equipment failure, one of which is failure to meet the operating requirements. We also established that servicing household appliances takes too much of the consumers’ time. They have to understand what consumables they need, when and where to buy them, and how to carry out the maintenance (themselves or through an agent). This article presents an instrument for the operation of products and services required by average consumers in their everyday lives. The tool is made up of a database that stores information about the useful life of different products by specific users as well as information about the maintenance, adjustment, and other actions required for the rational operation of the said products. The database will be used by specific vendors who will keep a database of their clients and products. Alternatively, a retail chain may keep a register of its clients and products sold to them and offer household appliance registration and maintenance services. The third option is creating a cloud service to register consumers, vendors, and service agencies.

Life-Cycle Contract as an Innovative Business Model for High-Tech Medical Organizations

The active digitalization of the healthcare system has given impetus to the emergence of a new type of enterprise—high-tech medical organizations (HMO). Their main distinguishing feature is the use of innovative high-tech medical equipment. However, the high cost of this equipment has become a factor slowing down the development of such organizations. This paper considers the life-cycle contract (LCC) as a special form of interaction between stakeholders and investments throughout the life cycles of equipment. Moreover, to provide technological support, continuous acquisition and life-cycle support (CALS) technologies, which are based on the same principles of working with the life cycle as LCC, are proposed. This question turned out to be a significant research gap, which was not sufficiently reflected in the available world studies. Thus, the aim of the current study is to describe the features of the use of LCC for HMO using CALS technologies and the impact of the life cycle of high-tech medical equipment on LCC, as well as to present the innovative component of the proposed model. Based on the analysis of the literature and the best world practices, the authors propose a visualization of the interaction of all stakeholders within the LCC for HMO. Such a decision is extremely relevant for developing organizations, public authorities and investors around the world.

The article discusses the production of microwave components based on the technology of low-temperature co-fired ceramics (LTCC). A set of standards Continuous Acquisition and Life cycle Support (CALS) and International Organization for Standardization (ISO) and business process models in these standards are considered. Based on the basic models of the ISO and CALS standards, a structural-parametric description model (SPD) has been developed, in which the structure of ISO-9000 is preserved, and specific parameters of LTCC technology are added. The methodology of the (SPD) of this technology is proposed. Open source software for processes, resources, results, production operations, control and management has been developed for each technological operation (TO), workplace and area. The methodology for creating information support and Microsoft Access Database Management System (DBMS) of SPD is proposed. Recommendations for the development of a software-methodological complex of information support for SPD of LTCC technology are proposed.

Ecological Monitoring of Road Chemistry Materials on Highways

The use of anti-icing reagents for road maintenance is accompanied by inevitable environmental consequences associated with the release of large amounts of chemicals into the environment. To reduce the negative consequences, environmental monitoring of the state of environmental objects is carried out, which makes it possible to assess the impact of the applied anti-icing reagents for the 4 most important environmental clusters: snow cover and water bodies, soil cover, green spaces and atmospheric air. At the next level of the developed monitoring system, specific geographic objects are shown. Samples were taken on 8 major highways of the city of Moscow. Environmental monitoring was carried out using a computer quality management system developed on the basis of CALS (Continuous Acquisition and Lifecycle Support) information technologies. 6 quality indicators have been added to the system for each geographic object: mass fraction of soluble salts, mass fraction of water-insoluble substances, pH value, specific effective activity of natural radionuclides, mass fraction of impurities and corrosiveness to metal. For each quality indicator, the system contains the most promising methods of analysis and instruments.

ДОСЛІДЖЕННЯ ПРИНЦИПІВ ПОБУДОВИ БАЗ ДАНИХ ЗРАЗКІВ ВИСОКОТЕХНОЛОГІЧНОЇ МАШИНОБУДІВНОЇ ПРОДУКЦІЇ НА ОСНОВІ БАЗОВОЇ МОДЕЛІ ДАНИХ NATO CALS

The need for the development of high-tech engineering in Ukraine requires the introduction of information technology at all stages of the life cycle of engineering products. This requires the implementation of the concept of Continuous Acquisition and Life-cycle Support (CALS), which has long been used in technologically advanced countries for the above purposes. Collection and processing of data generated by a sample of high-tech engineering products will be useful to reduce operating costs, increase service life, increase the speed of repair work, optimize according to various criteria of modernization of high-tech engineering products, promote the development of new similar samples of engineering products. The aim of the article is to determine the scientific basis for using the basic NATO CALS data model to build databases of samples of high-tech engineering products, including samples of weapons and military equipment. This goal is achieved by comparing the recommendations of NATO guidelines and Ukrainian opportunities to build information systems by machine-building enterprises and operators of their products. It is shown that the main theoretical approaches for building models of these samples of high-tech engineering products, given in the NATO guidelines on CALS-technologies and systems, are relevant. However, more modern and accessible tools are needed to build data models and database models, and the principles of semantic product breakdown and identification of entities, links and attributes can be taken from NATO guidelines almost without additions. As prospects for further research, it is proposed to conduct a comparative analysis of notations, modeling languages ​​and software products that implement them for modeling data of high-tech engineering products.

CALS conception for the educational program at the university in the study of metrology and other technical disciplines

The educational program at the university is designed taking into consideration the university wishes and the requirements of regulatory documents. The basis of the training program is the curriculum. It contains academic disciplines with the appropriate parameters: a semester, a number of credit units, the number of hours for classroom work, types of classes. For its implementation the resources are used: a lot of teachers (in departments), a lot of students (in groups), a lot of classrooms (for classes), a lot of equipment (of various types), a lot of training materials, a lot of e-learning courses. Many academic disciplines are combined with each set of resources. Each resource has its own parameters. To allocate the resources, these parameters and many conditions should be considered. This is a multi-criteria optimization task. The resource parameters and restrictions can change during the educational program’ functioning. It requires the development of a new educational program plan. This can be done using the concept of Continuous Acquisition and Life-Cycle Support (CALS) which is widely used in industry but not in education. The CALS concept is based on the use of automated information systems.

Integration of PDM and ERP systems within a unified information space of an enterprise

This article focuses on the research on the complex processes of joint integration of PDM and ERP systems. The relevance of introducing an integrated system within a single information space is justified. The main challenges of systems integration under a unified automation approach are described, including production planning and better management of production data. To successfully solve such problems ERP system needs to operate a certain amount of reference data, without which the production plan will be ineffective or impossible. Due to the fact that such data is often generated and stored in the product data management systems, it becomes necessary to provide data exchange between ERP and PDM systems. A number of key issues relating to the development and establishment of systems are determined. The functions of ERP and PDM systems that require a creation of an interaction interface between them are allocated and described. In conclusion, the positive trends, achievable through integration are reviewed. Keywords:-integration, Enterprise Resource Planning (ERP), Product Data Management (PDM), Unified Information Space (UIS), Continuous Acquisition and Life-cycle Support (CALS).

Developing a conceptual model for sharing container terminal resources: a case study of the Gamman container terminal

It is an important matter closely connected with saving logistics costs, as well as encouraging national competitive power, to improve the productivity of container terminals by efficient utilization of container terminal resources. In this respect, this paper tries to suggest a conceptual model for sharing container terminal resources, taking as a case study the Gamman Container Terminal (GCT) in the port of Pusan. In so doing, it identifies what kinds of resources can be systematically shared from the viewpoint of their common use and draws some problems resulting from terminal operation by four operators at GCT. The model does not imply the conception that each terminal has its own resources individually, but recommends that tentatively-called Container Terminal Resource Management Center (CTRMC) should be established and operated in order to save operation and investment costs and improve operational efficiency. In addition, the continuous acquisition and life-cycle support (CALS) concept is imbedded in the model so that it can control the supply and demand of resources efficiently by sharing the database, through which the CTRMC can automatically identify the status of the excess or deficit of a certain resource in each berth at GCT.
