MODELLING OF INFORMATION SUPPORT FOR CARGO TRANSPORTATION
Journal Title: Економіка транспортного комплексу - Year 2018, Vol 32, Issue
Abstract
The article deals with the approaches to the definition of "information support". The analysis of existing approaches suggests that some authors agree that information support is a system of in-formation or up-to-date data about the operation of an object of management. The rest of the au-thors suggest that information support is a means, or a set of means for displaying information and making decisions. The definition presented by the author combines the existing definitions into the integral whole and allows to reveal more fully the functional content of the information support. In the article the choice of the approach to modelling the information support of cargo transportation is grounded. The methodology of the functional modeling IDEF0 is well-designed and tested in practice, it is accurate and concise. Some authors believe that the system of logistics information support has five levels. Therefore, it is advisable to model the information support from the lowest level. In the article a context diagram of the "Cargo transportation" block is presented, and inputs, outputs, control, and mechanisms for it are identified. Then the first level is decomposed, and a di-agram describing the model of information support of the indicated block in more detail is con-structed. The decomposition diagram presented in the article contains 4 blocks: the work of the dispatch center, the work of the terminal of the departure point, the work of the freight forwarder and the work of the terminal of the receiving point. Each block of the diagram describes the corre-sponding syntax elements of the graphical language IDEF0. The article contains the detailed ex-planations to the given diagrams. The proposed functional model of information support of cargo transportation allows to determine the main functions of this process and, accordingly, to deter-mine the composition of information that will ensure their implementation. The next step in model-ling is the development of a scheme of information flows and documentary supporting.
