After analyzing and studying the characteristics of the sequence generation of grey system theory, this paper proposes the concept of three - dimensional data sequence, extends the grey system theory from one - dimensional data sequence to three - dimensional data sequence and enlarges the application range of the theory in engineering. this paper also proposes a decomposition coefficient selection method and a partial concave - convex characteristic decision method to the preference generation, which can solve the problem that the internal point generated by the original method was inconsistent with the actual system. considering the errors existed in ends generation with step ratio and smooth ratio methods, the author proposes a tendency average generation and improves the quality of the generation greatly
灰色建模與逆向工程兩者有其十分相似的內在關系，本文通過學科交叉，深入研究兩種不同學科理論，在繼承灰色系統理論這一我國原創性理論思想的基礎上，補充和豐富了新的內涵並將其滲透到逆向工程中的數據測量與數據處理技術的應用之中，使機械工程中甚少應用的這一灰色系統理論得到了進一步的拓展，主要成果如下: 1 .分析研究了灰色系統理論中序列生成的特點，提出了三維數據序列的概念，將灰理論的一維數據序列拓展到三維數據序列，拓寬了灰理論在工程中的應用范圍;提出了有偏生成演算法中生成系數分解選取方法和數據序列點局部凹凸特性決定生成系數的方法，解決了原有方法生成內點與實際系統不一致的現象;針對級比和光滑比用於生成端點有較大誤差的情況，提出了趨勢均值生成演算法，大大提高了端點生成的精度。
