Optimization of 3D Tolerance Design Based on Cost–Quality–Sensitivity Analysis to the Deviation Domain

Automation, 2023
Under the new geometric product specification (GPS), a two-dimensional chain cannot completely guarantee quality of the product. To optimize the allocation of three-dimensional tolerances in the conceptual design stage, the geometric variations of the ...

The Fault-Tolerant Facility Allocation Problem [PDF]

SIAM Journal on Discrete Mathematics, 2009
We study the problem of Fault-Tolerant Facility Allocation (FTFA) which is a relaxation of the classical Fault-Tolerant Facility Location (FTFL) problem [1]. Given a set of sites, a set of cities, and corresponding facility operating cost at each site as well as connection cost for each site-city pair, FTFA requires to allocate each site a proper ...

Geometrical and dimensional tolerance analysis for the radial flux type of permanent magnet generator design

Journal of Mechatronics, Electrical Power, and Vehicular Technology, 2021
Mechanical tolerance is something that should be carefully taken into consideration and cannot be avoided in a product for manufacturing and assembly needs, especially in the design stage, to avoid excessive dimensional and geometric deviations of the ...

Discrete tolerance allocation for product families [PDF]

Engineering Optimization, 2012
This article extends earlier research on the discrete tolerance allocation problem in order to optimize an entire product family simultaneously. This methodology enables a top-down tolerancing approach where requirements at assembly level on products within a family are allocated to single part requirements.
