Embodiment Construction

[0026] Linear optimization is one of the main methods in the field of mathematical optimization, and its study optimizes linear objective functions through sets bounded by linear equations and inequalities. Linear optimization is the basis for solving methods for (mixed) integer linear optimization.

[0027] Advantages of linear optimization:

[0028] - Global optimization scheme.

[0029] - Easily expandable.

[0030] - Very good commercial standard solvers (SCIP, CPLEX, Ilog, Xpress) which are widely spread and proven to work in practice.

[0031] - For the obtained solution, the maximum distance (Gap) from the optimal solution is known.

[0032] figure 1 Assembly system 100 is shown. Assembly system 100 includes a plurality of assembly lines 110 and a control device 115 for associating printed circuit boards 120 to assembly lines 110 . Each assembly line 110 generally includes a conveyor system 125 and one or more assembly robots 130 . Each assembly robot 130 include...

Abstract

The invention concerns a fitting line which is arranged to fit printed circuit boards with electronic components. A method for determining equipment families for the fitting line comprises the following steps: initial forming of a number of equipment families, each having allocated printed circuit boards; selecting of one of the equipment families; and distributing of the printed circuit boards of the selected equipment family to the other equipment families by means of integral linear programming.

Description

technical field [0001] The invention relates to a method for forming groups of equipment on an assembly line. The invention also relates to a control device for a production or assembly line for assembling printed circuit boards from components. Furthermore the invention relates to a computer program product and a computer readable medium. Background technique [0002] Especially in the field of electronics, printed circuit boards or components to be manufactured are manufactured by surface mounted technology (SMT) on SMT assembly lines. [0003] DE 10 2009 013 353 B3 shows a method for equipping such an assembly line. [0004] An equipment group is defined as a collection of printed circuit boards that can be assembled on an assembly line without changing the collection of component types that are ready for assembly on the assembly line. Existing tools for determining equipment groups often either require manual effort or provide results that are not always convincing. ...
