桌球競賽三次單淘汰系統之研究

我國2014年參加桌球少年菁英賽比賽參賽人數為2,355人，不但為數眾多，同時每年參賽人數均在成長中，為了便利於編排賽程還有抽籤之公平性；本研究目的是將國際殘障桌球競賽使用之單淘汰系統，修正為三次單淘汰系統方式。研究結果顯示：在符合國際比賽抽籤規則前提下；突破性的改變原本落敗者先抽籤並逐一抽下一次賽程籤位的方式，改為由裁判長執行電腦統一抽籤，以符合機會相等的公平性，也作了革命性的競賽流程改變，使比賽抽籤更加迅速。由於對戰圖之人數眾多，透過競賽程式之使用後，也能在短時間內完成繪製，更方便了競賽組的工作效率，也突破性的決議三次賽抽籤籤位不重覆，提升參賽者對第二次和第三次抽籤的期待，不會使遠到的選手又和在第一輪又和上次賽同一選手對上，這樣的改變都是改善傳統人工抽籤，同時解決耗費大量時間的問題。而競賽程式的協助更得以有效的提升競賽的公平性和競賽效率，方便國內舉辦多人和多次單淘汰的比賽制度。因此，本程式之開發除得以有效提升大會競賽水準外，未來更可以作為辦大型比賽的多次單淘汰參考。

In 2014, there were 2,355 youth players who participated in the national youth table tennis championships. The numbers of participants have grown steadily over the years. We would like to organize a fair and timesaving drawing system. The purpose of this paper was to modify the single knock out system of international para table tennis competition by the three single knock-out competition system. This paper concludes that it is a revolutionary change in competition procedures. In the past, losers had to ballot position first. Currently, all players ballot at the same time by a referee using the computer system. This unified draw is in compliance with equal chance for all players. Because of the large number of tournament bracket in the competition, we may use the program to complete the new draw in a short time. The drawing system also determines the position number cannot be repeated at three times. This prevents the players from competing again in the first round. Such changes improve the traditional manual draw, while addressing the problem of time-consuming. The effective competition program may enhance the fairness and efficiency of competition, and assist organizers held the multi knock-out tournament system. Therefore, the development of this program effectively enhances the competition level and the system can help organize a major game, using this multi knock-out competition system for table tennis.
