| 英文摘要 | In this paper we extend the notion of N-Policy, to a general set up in the case of (s, S) and production inventory systems. In [6], we considered the N-policy under which a replenishment was made through a local purchase when the number of backlogs becomes N during a stock-out period. Here we generalize the concept as follows: if the number of back-logs during a stock-out period falls to an element i of the set A = {α, α+ 1, …, α+γ- 1} for the first time during a lead time, a local purchase is made according to the probability distribution P = {βα, βα₊₁,…, βα₊τ₋₁}, where βi = Probability of order being placed when the inventory level falls to i ∈ A, (βi > 0 and ∑□βi = 1). However, a local purchase is made with probability one at the (α+τ)th demand epoch during a stock-out period. As in [6] here also we discuss three cases of replenishments. In the first case a local purchase is made to raise the inventory level to S after cancelling the order placed. In second and third cases a local purchase is made to raise the inventory level respectively to s and zero without cancelling the order placed. A similar generalization is made in the case of production inventory system also. |
