中文摘要：
在装备研制阶段，装备的研制费用是装备寿命周期费用的重要组成部分，对整个寿命周期费用具有重要影响，通过建立新的模型，使决策者能够更准确地确定装备研制阶段年度费用分配。描述了Vague集的含义和模糊熵，进而根据Vague集模糊熵能够对不精确和模糊信息进行有效表达的性质，提出了运用Vague集模糊熵对装备研制阶段费用按年度分配的新模型。在运用装备研制费用年度分配模型时，首先由专家投票来建立评判距阵，然后对评判距阵进行量化处理，根据量化处理结果来计算Vague集的模糊熵，最后通过Vague集的模糊熵来确定装备研制费用年度评估权值，从而确定各年度资金分配金额，弥补了Fuzzy集在不确定性方面的不足。算例表明了该模型的合理性与有效性。
英文摘要：
In the equipment developing stage, the expense of equipment developing cost is an important part of the equipment life cycle cost, and has a significant influence on the whole life cycle cost, this paper presents a new model which can help the decision - maker accounting the expense of equipment developing cost. In light of Vague sets, the meaning and fuzzy entropy of Vague sets are described. Based on the characters of Vague sets that can deal with the fuzzy information exactly, a new annuity distributive model of equipment developing cost is advanced. In using the model, the judgment matrix is first established by the experts, and then handled quantitatively. Based on the results obtained the fuzzy entropy of Vague sets is calculated. Finally, the fuzzy entropy of Vague sets is used to determine the development cost of equipment weights and the amount of annuity. A practical example shows that the model is reasonable and effective. This model can be used as a reference when decision makers distributing capital, so it is of a certain practical value.
