Mokrozub V.G. Functional and procedural models in technological equipment design

Abstract: the article presents a functional model (diagram) of the process of designing technological devices. The diagram includes steps of structural and parametrical synthesis of the device and its elements. Based on the functional design model the procedural model is created. It’s meant for converting the information flow defined by the terms of reference into the information flow for the working draft. Terms of reference defines a set of device functions, conditions of its interactions with user, workspace and environment. Working draft includes sketches, specifications, calculations and other documents. Functional diagram is created using IDEFO technology. Procedural model is represented by a set of formal statements, ways of converting input information flows in the output information flows. Procedural model of designing technological devices is characterized by the use of the following models: information and logical model of the designed equipment, model of processes taking place in the device, model of manufacturing technology of the technological equipment. The developed functional and procedural models can be used as a base for creating intelligent automated systems for generating project documentation with minimum human involvement.


Keywords:
