스포츠의 경기실적 산정모형의 분석 (농구의 평가공식을 중심으로)

Abstract

This study was intended to examine whether the existing player assessment formulas by the sports game factors sufficiently explained/assessed a quality of games for a high reliability between the calculation-relevant parties in calculating a part of sports game results which impacted the sports player assessment, and to investigate why a difference between the sports game results and an evaluative result of player`ss actual value occurred, This analysis assumed that there was a contradiction in the player assessment for the sports game results, Searching how the players assessment has been done so for and what advantages and disadvantages of assessment are, could be a basis for structuring the assessment model. The model for the study analyzed the Power Ranking Formula per position expressed by Sports Cosun (records×(40/total playing time), Rank ER Index of NBA (ER=A-B/total number of athlete play), assessment formula of KBL`s player contribution (assessed score of sports game results =extra score per item - deduction per item), NSP/SP formula of Harder, the contribution formula of Sports Chosun (contribution =points +rebound +assist +steal+ block +defense +minutes]-[error =number of failed shootings]), and ATR formula evaluating the point guard (ATR=assist (error), First, `Sports Chosun` has the meaning of players comparison per position, but cannot do the relative comparison between positions and doesn`t provide an exact mathematical information, Second, ER has a similar computing method to the formula of `Sports Chosun` except that its mathematical information is more concrete. It is not reasonable method to evaluate all players at the same time, Third, KBL`s formula accepted a diversity of assessment methods compared with other formulas, There are factors of addition/deduction even in some section, It attempted to carry out the player assessment such as granting the same weight in a concrete way, However, variables which are absolutely necessary for the assessment of underground results and extension of addition/ deduction need to be generated. Also, an objectivity of weight for a removal of voluntary grant is required, Forth, ATR formula evaluates the part of player`s ability, but nobody can know whether the results are influenced by any role, Compared with other formulas, this formula is very improper, Fifth the formula of `Sports Seoul! is almost consistent to the formula that deducts the weight in KBL formula, It is very similar to the KBL formula except an easy calculation of the formula, Consequently, a careful consideration is required, Sixth the formula of Harder seems to have the save context of flow as the formula of KBL and `Sports Seoul`.
