利用模糊结构元方法，研究允许缺货条件下模糊库存模型的求解与多目标决策问题。首先，介绍了经典库存模型，并定义了模糊库存模型。之后，在模糊结构元理论的基础上，得到了模糊数多元运算定理，在该定理的基础上确立了模糊经济批量公式的解析表达形式。由于确定最优经济批量是一个多目标决策的问题，因此，在得到最优模糊经济批量的基础上，采用分层序列法来求解该问题，进而得到了考虑企业战略规划、竞争对手和资金约束等因素的经济订购批量。最后，通过算例求解对比，模型适用范围更广且求解更为简捷。

This paper studied the approaches to solve the fuzzy inventory model and the multi-objective decision-making under the condition of out of stock by using the structured element method. First of all, the classic inventory model is introduced, and the fuzzy inventory model is defined, and then on the basis of fuzzy structured element theory, an operator theorem for multi-fuzzy numbers is reached. On the basis of this theorem, this study established the analytical expressions of the formula of fuzzy economic batch quantity. As solving the optimal economic batch quantity is a problem of multi-objective decision-making, the problem is solved by using a hierarchical sequence method on the basis of solving the optimal fuzzy economic batch quantity, and then economic order quantities is figured out when some factors is considered such as strategic planning of business, competitors and capital constraints. Finally, by taking examples and comparisons, the results show that this model is much simpler and can be broadly applied.
