Swimmer selection optimization strategy research based on SPSS factor analysis

Swimming is a sport that lays equal stress on endur ance and technique, sound technique is guarantee of scientific exertion that makes contribution to swimming techni que rationality and improvement direction. Utilize factor analysis method and integer programming model metho d; make application of mathematical model into comp etitive swimming. In research process, it respectively from athlete perspective adopts factor analysis method providing swimming strategy for athlete, from coach perspecti ve utilize integer programming finding out optimal athletes assignment scheme and competition best total score; Make improvement based on precedence algorithm, ap ply sensitivity analysis, on the condition that optimal solution not changing, get athletes assignment per formance intervals. Through this paper’s research methods, a nalysis routes and research results, it provides re asonable suggestions and theoretical basis for swimming tech nique.
