Study of Grey Relational Generating and Development of Toolbox by C Language

Through the review of related studies of grey relational generating, we aim to present the five methods of grey relational generating and describe the whole mathematics calculation steps in detail. Based on the large data calculation and analysis, we also create a C language toolbox for the calculation and verification of a large number of complex numerical values. Two real examples such as drinking water and transportation are evaluated by using a computer toolbox to verify the final results. After actual calculation and analysis, the overall content of grey relational generation is verified to enhance the completed grey system theory.
