The majority of municipal medical institutions are not working effectively enough. Long waiting in the queue to see a doctor is one of the most significant problem of the organization in the field of healthcare. The SADT (Structured Analysis and Design Technique) methodology was used to find out the problems of functioning of the medical center. Functional diagrams of the subject area were constructed, which helped to understand how individual business processes of the organization that need to be optimized are implemented. A simulation model of the medical center "Detstvo+" in the GPSS World programming language has been developed. it is an open Queuing network consisting of 5 large nodes that are Queuing systems, which allows us to imagine the process of functioning of the medical center. The model was optimized according to the efficiency criterion of this system: while maintaining the volume of the incoming flow of applications, the number of rejections is kept to a minimum, while it is necessary to reduce the length of queues for doctor appointments. This model can also be used by institutions with a similar organizational structure to improve their systems and make management decisions.

Objectives: The main aim of this study was to investigate the factors that influence students’, academicians’, clients’, as well as developer’s preferences in choosing their preferred approach in system development, namely structured analysis design (SAD) or object-oriented analysis and design (OOAD). Methods: The research design was based on a survey methodology and a case study. For the survey, questionnaires were administered to 30 students and 38 academicians, who were randomly selected from several Malaysian universities. For the case study, the requirements of the information system were modeled and presented to several clients to elicit their feedback. The survey data were analyzed using SPSS Findings: The result shows that students preferred the use of OOAD approach, which clearly outnumbered those who preferred the SAD approach, which stood at 33%. Interestingly, the majority (53%) of academicians preferred the use of a mixture of both approaches. Likewise, the clients shared a similar view with the academicians, whereas the developer preferred the OOAD approach. Application/Improvements: Clearly, the findings suggest that both approaches are essential, but the one that is widely used by developers and preferred by students is OOAD, and thus should be given priority when it comes to structured analysis and design. As such, curriculum designers and institutions of higher learning, particularly those offering system analysis and design and related courses, should make the necessary changes to the existing curriculum such that the academic programs offered will be able to produce highly competent and skilled analysts and designers as required by the industry.

IDEF0 (Integration Definition language 0) adalah suatu metode pemodelan sistem berbasis SADT (Structured Analysis and Design Technique), yang dikembangkan oleh Douglas T. Ross dan SofTech, Inc. Dalam bentuk aslinya, IDEF0 meliputi bahasa definisi dan pemodelan grafis (syntax and semantics) yang menggambarkan suatu metodologi komprehensif untuk membangun model. IDEF0 dapat digunakan untuk memodelkan berbagai jenis sistem baik yang otomatis maupun non-otomatis.

The article investigates the approaches of building business process, forming the strategy of the enterprise. The procedure of methodology usage for functional modeling and graphical representation of IDEF0 notation processes (English Integration Definition for Function Modeling) for the procedure of enterprise strategy development is presented. The algorithm of procedure modeling for forming the company's strategy is developed and for that the SADT (Structured Analysis and Design Teqnique) diagram and its decomposition by the main elements and stages is presented.

Currently, the methodology of system engineering is being formed, the product of which is, as usual, the creation of real objects information models, supplemented by virtual components, and on the contrary, virtual objects, supplemented by real components. For example, an information model of a technological object is a specification of real equipment, supplemented by a specification of the purchased equipment of a technological process and on the contrary. By analogy with general engineering in the field of technical activity, the metastructures of such information models must meet the V-shaped structure of the validation and verification processes. Therefore, models should be regularly checked during their life cycle to ensure that their structure and parameters correspond to real and virtual objects. At the present, there are conditions for a coordinated decision of technological objects system information modeling, taking into account their internal (physical) structure and of the digital environment the external structure. In general theoretical terms, the construction of system models is based on the problem of formal consistent description (grammatical calculus) of the structure and functional regularities of a set of objects and their connections in the subject area under study. The presented approach of the subject area system modeling under consideration is based on the classical model of a machine-building enterprise (MP) educational and production activities and a university. Aim. To apply the principles of the design approach for the formation of a corporate information system (CIS) engineering company metastructure digital twin, to explore the prospects of its application, to show the key information components in the management of subject-oriented knowledge and data, as well as the ability to scale technology in the formation of a digital environment for architecture and modern MP, improving the efficiency of business processes participants interaction. Materials and methods. The principles of the system engineering methodo¬logy (process approach, life cycle, etc.), an integrated approach and structural analysis of the design process according to the SADT (Structured Analysis and Design Technology) methodology, and the TOGAF (The Open Group Architecture Framework) methodology are used. Results. The proposed approach for system modeling the subject area is the development of works of the authors, demonstrates the possibility of scaling on the example of interaction of participants of the REC using part of the University's digital twin KIS enterprises of the real sector of the economy. The requisite of developing a knowledge management model and the increasing role of information search engines are shown. Conclusion. The proposed approach expands the application of the digital twin metastructure, allows correcting the enterprise architecture to improve the efficiency of business processes.
