Abstract: To solve the problems of the poor reflection of plans and being easy to be controlled in traditional Borda method,an algorithm to improve Borda score was proposed.The algorithm puts the integer and individual into considera-tion,takes the idea of improving score in fuzzy Borda method and interactions among members in SPAN method,and improves Borda score matrix.The method calculates the integrated value with formulas in weight,and sorts the plans by integrated value.At last,the accuracy and reasonableness of the algorithm were verified.
