Modelling Complex Production Processes in Aerospace Industry based on Dimensional Analysis

This paper looks at the application of the principals of dimensional analysis to identify relations between key parameters of the production system in order to construct a process model that can quantitatively describe the influence of manufacturing process variables, type of technology employed and the material flow on the integral productivity for both batch and flow production architectures of the aerospace production facilities. This process model allows the construction of closed cycle production chains for aerospace parts that form critical path in the assembly sequence of the final product. This approach has been successfully applied to solve the problem of the manufacturing process sequence and material flow optimization for gas-turbine compressor blades production. In conclusion one can say that the developed production process model allows to obtain a numerical assessment of the change in integral productivity as a result of controlled variation in parameters of the manufacturing system which in turn allows to design effective production systems based on optimization of the system parameters.
