Abstract
A computer solves an item-based one-dimensional sub-optimization problem independently of the other items. For the item-based solution found, the computer determines whether machine interference between the items is eliminated and whether a work-in-process inventory is sufficient. If machine interference is not eliminated or the work-in-process inventory is not insufficient, then the computer updates a corresponding Lagrange multiplier and reexecutes the solving of the problem.
