Abstract
This paper is devoted to the problem of planning and control of the labor intensity of manufacturing aircraft gas-turbine engines (GTE) at the early stages of design. The paper deals with an original approach to the definition of the complexity of the gas-turbine engines manufacturing, which is a multivariate and streamlined procedure based on a model for phased complexity calculation. The suggested system of planning and control of labor intensity is different from the known methods: this system uses engine components as a whole, or individual constituent parts and assembly units (PAU) generated at various stages of engineering design and technological characteristics of the estimated object. Unlike other approaches, the suggested model is to develop the planning and control of the labor intensity of manufacturing procedures of GTE at the early stages of design; it ensures the achievement of the competitive labor intensity in the course engine manufacturing. The difference also lies in the use of two-factor ABC-analysis of assemblies and PAU of engine on labor intensity and materials consumption that allows identifying key components and PAU of engine and significantly reducing the work on estimation of the labor intensity of designed GTE.
