DUAL_CYCLE_OPT
Dual-command cycle selection: pairs a store with a retrieve when the combined trip actually saves travel, and reports how much.
When to use it
Use DUAL_CYCLE_OPT when an AS/RS aisle has both putaway and order work waiting, and the machine's next task has to be chosen between two single-command trips and one dual-command trip that interleaves them.
