The assembly of printed circuit boards: a case with multiple machines and multiple board types

Article Abstract:

A heuristic approach to solving a common problem in the manufacture of printed circuit boards is presented. The problem involved the the assembly of different types of printed circuit boards using only a single line of placement machines. Decomposition of the main problem yielded a host of subproblems, the most important of which was the formulation of a feeder rack assignment that will result in an efficient placement sequence for each board type. The solution was subjected to real-life production testing where it proved its worth in enhancing efficiency.

Generalized semi-infinite programming: theory and methods

Article Abstract:

A study has been conducted to examine generalized semi-infinite optimization problems (GSIP) and to try to illustrate the difference between GSIP and standard semi-infinite problems (SIP). Illustrated examples reveal that Chebyshev approximation problems lead to semi-infinite problems and GSIP. Finding indicate that the numerical solution of GSIP can be more difficult than the solution for SIP. The transformation of GSIP to SIP may be possible if in all points of Y(x) the Mangasarian Fromovitz Constraint Qualification is satisfied.
