Two Probabilistic Models for Solving an Oxygen-bottle Inventory Problem
将氧气瓶库存问题建模为排队模型和概率目标规划模型，前者确定最优存储率，后者最小化总成本，并给出了埃及空军的案例研究。
In this paper, an inventory oxygen-bottles problem is formulated as (i) an (M/M/C):(GD/N/∞) queueing model with different service rates; (ii) a probabilistic goal programming (PGP) model. By using the first model, the optimum required rate for oxygen bottles to be stored is determined. By using the second model, the decision-maker can determine his policy, which minimizes the total cost. Finally, a case study of the storage of oxygen bottles for the Egyptian Air Force (1980-1984) is presented.
