WEB-TECHNOLOGIES FOR CONSTRUCTION OF AUTOMATED INFORMATION-MODELING SYSTEMS OF TECHNOLOGICAL PROCESSES IN METALLURGY

The features of software of information systems for the work of engineering and technological staff at metallurgical enterprises are considered. The software includes automated workstations, decision support systems, information modeling systems, expertsystems, etc. It is desktop applications written in high-level programming languages (Visual  C#, Visual Basic, etc.). Processing of technological information coming from the enterprise database management server (DBMS) includes the need to solve  Runtime package. However, the functionality, availability, and crossplatform portability requirements for modern enterprise information systems cannot be met in desktop applications that use Windows Forms. This is due to the search for a new technology and means of creating information systems. The most rational is the technology for building web applications based on theASP.NET MVC framework, which allows to transfer mathematical libraries, interaction modules with Microsoft Excel, MATLAB from Windows Forms without modification. The concept of the structure of a web application used in the development of software that meets modern requirements for the operation of information systems is presented. This concept suggests the availability of the following functional areas on the web page: logo and title of the current page, session status menu, functional menu, group operations, notifications and tworkspace.a set of mathematical programming problems, systems of differential equations, problems of mathematical physics, etc. Such tasks cannot be solved with the help of a standard set of mathematical tools for general programming languages. So the development of information modeling systems is carried out by interacting with external software  – Microsoft Excel and MATLAB. The interaction with Microsoft Excel is based on COM Interop technology, which assumes the installation of Microsoft Office software on each client computer. To interact with MATLAB, you must pre-assemble the library in the MATLAB Compiler environment and connect it to the program. The execution on the client computer is achieved by installing the freely distributed MATLAB
