Economical reorder quantities and reorder points with uncertain demand

摘要: The problem of determining reorder quantities and points that minimize the total costs carrying inventory, placing orders, penalties for back in face uncertain demand, is considered this paper. By making approximations to cost function safety factor versus service relationship, an economic order quantity derived depends on uncertainty foiecast demand during lead time, but independent cost. Reorder are then determined case which explicitly stated, unknown desired customer used as controlling parameter. Simulations indicate that, when compared with use Wilson quantity, formulae paper will approximately a 5-7-percent reduction
