Abstract
The article discusses the issues of analysis and design of a software application using CASE tools designed to automate the technological process of mixing and melting of copper concentrates. This work consists in the study of the processes of designing and modeling complex systems, as well as their application in the copper industry, in particular in the process of mixing and melting copper concentrates. This will allow you to better understand the control object, that is, it makes it clear how the various elements of the system interact with each other, as well as how to improve the management of the technological process, and optimize the work as a whole. These diagrams provide a wide range of tools and functions that allow developers to effectively design, model, and manage complex software systems, objects, and systems. Here, a description of the key steps of these diagrams is provided as part of this research work.
