最优质量水平 meaning in English

the best quality level

On the basis of the theory of the fuzzy optimize design and the fuzzy compositor and the normal engineering mathematics method , the mathematics models of confirmation of optimize quality standard and quality cost proportion in the design sage is put forward ; the real time control model in the construction stage is put forward based on the fuzzy control theory . the three models are all easily handled and precise and could be used in real work
本文运用模糊数学的原理，提出了工程设计阶段的最优质量水平的计算模型、最佳质量成本比例的计算模型；在施工阶段则根据模糊控制原理，提出了质量成本的实时控制模型。这三个数学模型都具有良好的可操作性和精确度，有一定的工程实际意义。
