Cost management for PLM systems: A way to improve the competitiveness in digital economy

Two of the most efficient ways of increasing digital economy systems' competitiveness are creating digital twins using PLM-based cost management instruments. Determining machinery's cost characteristics on the conceive step of their lifecycle is the most efficient if it's based on probabilistic approach. On the next steps of design process, such as concept design and detailed design, a designed construction's price should be estimated basing on its informational (parametric) complexity indexes. This price is to be compared with earlier estimated approximate parameters. The most efficient way of using presented approach is making it a part of CAx system (first of all, such systems as MCAD and EDA). It may be applied as a part of invariant subsystem of technical and economic parameters for the computer-aided account facilities and for simulation of processes (CAE, CAA). The most appropriate way of organizing design and development processes is to use AGILE ideology. This approach gives a possibility to create an integral system of creating digital twins that is useable on any step of product's lifecycle.
