Optimization models are proposed for selecting the required number of universal prefabricated devices and non-separable special devices. As a modeling apparatus, nonlinear programming problems and discrete dynamic problems are used. The work formulates mathematical models that allow implementing a management technique based on the principles: Just in Time, Design to Cost, Risks Management.
The reducing of machine time during surface hardening by smoothening is possible by increasing in the contact length between the hardening element and part surface. We study the case: the indenter-working surface is a fragment of a cylindrical surface, which the symmetry axis is parallel to the axis of symmetry of the part hardened surface. We suggest that such a process scheme is corresponds to a 2D contact problem in which a cylindrical stamp moves in an inertial coordinate system along an elastic half-plane (circle). We tasking the boundary conditions in the contact zone, using the complex potentials developed in the works of L.N. Galin.
The paper discusses the experience of introducing a developed automated system for integrating data directories from various, often unrelated and heterogeneous, information sources at the aircraft manufacturing enterprise Aviastar-SP JSC (Ulyanovsk, Russia). This automated system allows both manual and automatic modes to integrate the databases of directories used at the enterprise. To test the operability on real data, the developed system went through trial exploitation and gave good results.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
