Presentation a New Model for Measuring the Performance of Participating Nations at the International Game

Evaluation and ranking of countries participating in international games looks normal based on their earn medals. Traditional evaluation methods focus on results-based country is the number of medals acquired. But you knew that to achieve outputs competition (medals acquired) only in the context of utilization of inputs and using appropriate processes are possible. Purpose of this paper is presents a hybrid model of DEA / CSW to assess the relative performance of countries participating in the international game. The model in the paper considers two inputs (GDP per capita and population) and three outputs (number of gold, silver and bronze medals won). Efficiency scores can be considered country rankings. Different weights to the gold medal, silver and bronze medals for each country are calculated relative effectiveness and significance of the gold medals, silver and bronze not consider, perhaps in the performance of a country's medal, a bronze or silver worth more than give the gold medal. In this paper, a method of linear programming MaxMin to obtain a set of weights (CSW) is used. Finally, the method developed to assess the relative performance of countries participating in 2008 Beijing Olympic.
