Fuzzy-multiple approach in design and technology management modeling preparation of production at machine-building enterprises

As economic systems are characterised by influential uncertainties (or uncertainty factors), performance assessment in engineering enterprises requires a solid scientific background for managerial decision-making in business. This article offers a model of a fuzzy system for the development of design documentation at the design pre-production stage and technological documentation at the technological pre-production stage. The model aims to manage and frame the process of design and technological pre-production. Based on fuzzy logic tools, the model allows engineering enterprises to operate temporary parametrons of sequential and parallel-sequential processes involved in the development of design documentation and technological documentation. This study demonstrates that a fuzzy-set approach can serve as an effective means for design and technological pre-production management at engineering enterprises in a highly competitive market. Multiple scientific and technological improvements, together with the overall digital transformation of engineering, have driven core changes in business processes, their timing, and costs. Even with tighter deadlines for design and technological pre-production, managerial decisions are expected to fit them with sufficient flexibility to ensure mobility. This fact does not undermine the importance of general supervision and awareness of management over the existing bottlenecks in the entire production management system and in design and technological pre-production.
