Assembly Line Sequencing - The virtual assembly line contains slots
where orders are sequenced and queued before the real line. This sequencing
uses a set of business rules. An example is like this: cannot have three
sunroofs in sequence because the extra time repeated three times will slow
the entire line. With more products and options on the line, the rules expand
and this becomes a massive, rule-based, linear programming
problem.
