Heptathlon evaluation model using Grey system theory

In this paper we investigate the effectiveness of the Grey system theory to determine the ranking of the best women athletes in heptathlon. The scoring method currently used in women's heptathlon needs alternative scoring as it displays unacceptable bias towards some athletic disciplines while deferring others. The term Grey stands for poor, incomplete and uncertain, and is especially related to the information about the system. The Grey relational grade deduced by Grey theory is used to establish a complete and accurate model for determining the ranking of the heptathletes. The proposed scoring method is accurate and is shown to improve fairness and results' validity in women's heptathlon.
