Forecasting the quality of innovative energy machine engineering products at the stage of developing design documentation

In the article, design documentation is considered as a product that has both internal and external consumers. A list of internal consumers is provided, indicating their key needs in using this documentation. During the development of design documentation for energy machine-building products, its main properties and characteristics are established. Correcting errors and inconsistencies at this stage is less costly compared to later stages of the product’s lifecycle. Ensuring the quality of design documentation remains an important task, even in conditions of widespread automation and digitalization. This article proposes to consider product quality as a set of quality indicators at various stages of the product lifecycle. An original mathematical model is presented for evaluating the quality of the design documentation development process for innovative energy machine-building products, which unifi es various characteristics while taking into account specifi c indicators of local quality assessment at all stages of the product lifecycle. Since quality indicators for future lifecycle stages carry a certain degree of uncertainty, probabilistic methods are applied for their evaluation. The effi ciency of the design documentation development process makes it possible to compare the results related to the quality of the documentation with the costs and quality of the development process.
