Abstract
Purpose. The purpose of this paper is the construction of methods and models for the graphical representation process of sorting station, using the unified modeling language (UML). Methodology. Methods of graph theory, finite automata and the representation theory of queuing systems were used as the methods of investigation. A graphical representation of the process was implemented with using the Unified Modeling Language UML. The sorting station process representation is implemented as a state diagram and actions through a set of IBM Rational Rose. Graphs can show parallel operation of sorting station, the parallel existence and influence of objects process and the transition from one state to another. The IBM Rational Rose complex allows developing a diagram of work sequence of varying degrees of detailing. Findings. The study has developed a graphical representation method of the process of sorting station of different kind of complexity. All graphical representations are made using the UML. They are represented as a directed graph with the states. It is clear enough in the study of the subject area. Applying the methodology of the representation process, it allows becoming friendly with the work of any automation object very fast, and exploring the process during algorithms construction of sorting stations and other railway facilities. This model is implemented with using the Unified Modeling Language (UML) using a combination of IBM Rational Rose. Originality. The representation process of sorting station was developed by means of the Unified Modeling Language (UML) use. Methodology of representation process allows creating the directed graphs based on the order of execution of the works chain, objects and performers of these works. The UML allows visualizing, specifying, constructing and documenting, formalizing the representation process of sorting station and developing sequence diagrams of works of varying degrees of detail. Practical value. The usage of the Unified Modeling Language (UML) based on software package IBM Rational Rose and allows to create processes of varying degrees of detail, reduce the time expenditure for the process research of sorting station and get a clear graphical representation, as well as to reduce the human costs at the construction and improvement of existing technological processes.
Highlights
Modern information technologies are one of the priority directions of the development and improvement of transportation process management, operation of infrastructure, and other processes on railway transport.The main goal of informatization of railway transport is to provide all technological processes and activities of railway transport with the information and creation the information base for maximum efficiency of industry
Two diagrams of states and actions can be used for the modeling the process of sorting station at the logical level in the Unified Modeling Language (UML) system of IBM Rational Rose [10]
The methodology for the presentation of technological processes of sorting stations in the form of a sequential execution of the operations and the transitions between them, as well as representation the parallel operations and parallel action of object sorting station in these diagrams were proposed for the model development
Summary
Modern information technologies are one of the priority directions of the development and improvement of transportation process management, operation of infrastructure, and other processes on railway transport.The main goal of informatization of railway transport is to provide all technological processes and activities of railway transport with the information and creation the information base for maximum efficiency of industry. The main element of information systems of operational control in the train stations operation and the assessment of their technical and technological characteristics is the mathematical model of the technological process In this regard, the formalization of technological processes of railway transport is an important task for the railway transport. The formal representation of technological processes in the available form for their automatic and automated analysis is complicated enough
