| Abstract |
Optimization techniques are efficient to deal with sizing steps that designers have to
perform. However, their industrial usefulness is also subject to their ability to deal with tolerance
issues. Indeed, tolerances may have significant effects on device reliability. They can come from a
wide range of sources, such as environmental changes, manufacturing tolerances or aging. A generic
methodology has therefore been devised, to account for tolerances while sizing a device. It is based on
the use of unconstrained optimization processes inside sizing models. Hence, the building of those
sizing models becomes more complex. However, this additional complexity can be partly hidden to
the designer, using appropriate software tools. The efficiency of the proposed approach is shown here
on an industrial example, which involves the design of a current measurement transformer. Eventually,
this methodology is believed to be general enough to be applied in other technical domains. |
