Games factored in the new FIBA World Ranking Men, presented by Nike All games played by 149 national teams in top official FIBA competitions and their Qualifiers over an 8-year period. METHOD 1.Calculate the rating points(RP) for each game to wach team; 2.Calculate the ranking according to the weighted average rating points of each team, over all games in previous 8-year period. METHOD Stage 1 - Calculate each team's rating points allocated from each team 1,000 basis points(BP) are awarded in each game according to the following principles: - Win by a margin of 1-9 points -> reveive 600 basis points - Win by a margin of 10-19 points -> reveive 700 basis points - Win by a margin of 20 or more points -> reveive 800 basis points - Lose by a margin of 1-9 points -> reveive 400 basis points - Lose by a margin of 10-19 points -> reveive 300 basis points - Lose by a margin of 20 or more points -> reveive 200 basis points - In the event of a game being forfeited, the winning team receives 800 points (for a victory by a margin of 20 points) and the losing team 0 basis points 程序1：计算rating points(RP) RP=BP+HAP+ORP BP(basis points) 每场比赛分配给两队共1,000BP的分数 - 胜分在1-9分间，拿600BP - 胜分在10-19分间，拿700BP - 胜分在20分或以上，拿800BP - 负分在1-9分间，拿400BP - 负分在10-19分间，拿300BP - 负分在20分或以上，拿200BP - 在被没收的比赛中，胜队拿800BP，败队拿0BP Home and away games, neutral games The concept of home and away games in in place for Qualifiers and top official FIBA competitions. At top official FIBA competitions, home and away games are in effect only for the host and their opposing team on the given day. All other games are considered to be played on neutral ground. For example, at the FIBA Basketball World Cup 2019, host China will play all of their games as the 'home team' and therefore all of the opponents they will face will be the 'away team'. Meanwhile, all non-China games will see teams play on neutral ground. The home or away points(HAP) are given by: ┌───────────────┬──┐ │Situation │HAP │ ├───────────────┼──┤ │Game at home │-70 │ ├───────────────┼──┤ │Game at neutral venue │ 0 │ ├───────────────┼──┤ │Game away(opponents are home) │+70 │ └───────────────┴──┘ A win away from home results in a bonus as it is typically harder to win on the road. HAP(home or away points) 主客场积分 在资格赛及锦标赛皆适用。锦标赛仅在主办国及其对手国家的比赛场次有主客场队之分， 其余比赛场次皆属於中立场地赛事。 主场队 -70HAP 中立场队 0HAP 客场队 +70HAP Strength of opposition factored in A win by a team against an opponent that is higher in the FIBA World Ranking Men , presented by Nike, means the result will be worth more points for the winners. The opposition ranking points(ORP) are given by: ORP=1.5x(AVG ALL-TEAM PRE-GAME RANKING-OPPONENT PRE-GAME RANKING) The ranking rewards teams for facing opponents ranked higher than them. The higher the opposition is ranked, the more points the team stands to get. As the best teams are naturally ranked higher, playing strong opponents means their ranking will be lower numerically than the average all-team pre-game ranking. Therefore, this conrtibution will be positive. Conversely, the weaker team have higher than average ranking so this contribution will be negative. ORP(opposition ranking points) 对手排名积分 ORP=1.5 x (所有球队赛前排名平均-对手赛前排名) 这是奖励面对较高排名球队的积分。对手的排名越高，能得到越多的积分。 对手是较强的球队排名会小於所有球队赛前排名平均，则计算後ORP会是正值。 对手是较弱的球队排名则会大於所有球队赛前排名平均，计算後ORP会是负值。 The final rating points(RP) for the game for a team are given by the following formula" RP=BP+HAP+ORP 一场比赛给球队的最後积分(RP)依据以下公式计算： RP=BP+HAP+OAP RP:rating points BP:basis points HAP:home or away points ORP:opposition ranking points Updating the FIBA World Ranking Men, presented by Nike, at any time. METHOD Stage 2 To calculate the ranking at any pearticular time, we have to calculate the rating points for all teams at that time and then rank them. 程序2： 在任何特定的时候计算排名，必须计算当时所有队伍的比例然後排名 We calculate the ratings by taking a penalised weighted average of rating points from their previous games. To calculate the weighted average, we need to calculate the weight(W) for each game. 我们由先前得到比赛得到比例分数的惩罚重量平均来计算比例。为了计算重量平均， 我们计算每场比赛的重量Weight(W) The weight is made up of following factors: ┌──────────────┬───────────────────────┐ │Factor │Description │ ├──────────────┼───────────────────────┤ │Time since game │Games are weighted so that more recent ones │ │ │contribute more to the rating. Games more than│ │ │8 years old are not taken into account. │ ├──────────────┼───────────────────────┤ │Region of competition teams │Weights are given to the region of the │ │ │competition to ensure competitive balance. │ ├──────────────┼───────────────────────┤ │Stage │Weights are given according to the game being │ │ │played in Qualifiers or at Top competitions. │ ├──────────────┼───────────────────────┤ │Round │Weights are given to the round of the game ( │ │ │Top competitons only), with games in later │ │ │rounds more highly weighted. │ └──────────────┴───────────────────────┘ 重量由以下因素组成： 因素 叙述 距离比赛时间 越接近的比赛形成越高的比例。超过八年的比赛将不被计入 参与比赛的区域 比赛的区域被赋予重量以确保公平竞争 层级 重量会分别依据是资格赛或是顶级锦标赛而给予 轮次 重量会依赛事的轮次被给予(仅在顶级锦标赛)，越後面的轮次重量越高 Time decay(TD) A time decay factor is implemented to reward teams for most recent performances and in order to prevent all games over the 8-year period from carrying the same weight and receiving the exact same value. 时间的衰退Time Decay(TD) 履行时间衰退的因子是奖励球队近期的表现，为了防止八年间所有赛事都具有一样的重量 ，并得到确切一样的价值。 ┌──────────┬────────────────┐ │Time of game(TD) │Weight │ ├──────────┼────────────────┤ │Y(current year)&Y-1 │1 │ ├──────────┼────────────────┤ │Y-2 & Y-3 │0.75 │ ├──────────┼────────────────┤ │Y-4 & Y-5 │0.5 │ ├──────────┼────────────────┤ │Y-6 & Y-7 │0.25 │ ├──────────┼────────────────┤ │Y-8 and before │0(not taken into consideration) │ └──────────┴────────────────┘ 比赛的时间(TD) 重量 Y(当年度)及Y-1 1 Y-2及Y-3 0.75 Y-4及Y-5 0.5 Y-6及Y-7 0.25 Y-8及更早 0(不被纳入计算) The reason for this is to add a form factor that rewards teams slightly more for better results in recent history. 加入这种形式的因素是为了奖励近期表现更好的队伍。 Comprtition and region weights(C) Weights are gibven to different competitions to reflect the prestige of the tournaments and to ensure that ratings are comparable across regions. 赛事及区域重量Competition(C) 在不同赛事给予不同重量以反映锦标赛的声望，并确保比例可以在区域间比较。 赛事/区域(C) 重量 FIBA世界盃 2.5 奥运篮球项目 2.0 非洲区 0.3 美洲区 0.8 亚大区(及前亚洲区)* 0.4 欧洲区 1 前大洋洲区* 0.7 *自2017年起，亚洲及大洋洲在同一区竞赛，但在2010-2016两个区域是分开进行的比赛结 果，这个因素将在八年後消失(2025年) 赛事层级重量Stage(S) 比赛越重要，在计算比例时重量会越重。 层级(S) 重量 资格赛会前赛 0.25 资格赛 0.5 顶级锦标赛 1 轮次重量Round(R) 根据赛事系统升级到单场比赛系统，新的由Nike呈现的FIBA成年男子世界排名，被依照轮 次给予不同重量，得到较多或较少重量取决於比赛在哪个轮次(仅在顶级锦标赛)。 顶级锦标赛* 轮次(R) 重量 小组赛 1 16强 1.25 八强 1.5 四强 1.75 决赛 2 *包含FIBA世界盃、FIBA洲际盃及FIBA奥运资格赛 *对那些不是依照确切竞赛形式的锦标赛(例如：没有16强或八强)，重量会根据锦标赛中 轮次的数量按比例给予，球队会依晋级的轮次得到 参与比赛在平均惩罚重量的最後重量W的公式为： W=TD x C x S x R W：最终比赛比例 TD：时间衰退 C：锦标赛及区域重量 S：赛事层级重量 R：轮次重量 目前的方式让所有参与资格赛(不须进到会内赛)的球队都能在每场赛事获得积分。且每场 比赛的胜负分都将关系到积分多寡，简单来说不再轻易有消化比赛或垃圾时间出现。 按：由於东京奥运资格赛的剩余参赛权将由FIBA排名选出，故解释目前FIBA排名计分方式， 与以前每个锦标赛按照名次乘上赛事比重得到分数累计有不小的落差。先暂时放上第 一段积分方式，後续解释容後补充。 --
