Grey prediction model-based GM (1, 1) 100m performance prediction applied research

摘要

Grey system theory is a kind of ideal method in processing small samples dynamic development problems, and 100m race speed problem has “poor data information”, “small samples” and “dynamics”, it lets grey system to have advantages over traditional probability statistics and fuzzy mathematics in its problem research, grey mathematics’ application in competitive sports performances prediction and analyses are more and more extensive. The paper applies documents literature, makes statistics of year1992~2012 every session Olympic Games’ 100m race best performances. Establish GM (1, 1) grey model on them. By using GM (1, 1) model, it predicts next session Olympic Games 100m best performances, and states GM (1, 1) model methods application in multiple events sports competition.
