Introduction Typically, the goal of setting inventory control is to effectively coordinate the acquisition, manufacturing and releasing of materials to meet market needs [1].
Lot sizing is not used, so quantity can be ordered and delivered and any allocation rule for material rationing to the local stock points is allowed (as far as the allocation quantity are non- negative). 7.
