碩士 === 國立中央大學 === 土木工程學系在職專班 === 105 === The performance record of professional sport organizations often affects their income and is the key deciding factor for their long-term survival. The first professional sport organization that appeared in the United States is baseball, and its inning-based feature has enabled high level of statistical data transparency for the various game and facilitated statistical analysis. In addition to evaluating the team salary structure and the player's career performance models, ample studies have also investigated prediction models used to analyze weather certain teams can enter the playoffs. The rate of accuracy for empirical analyses conducted by such studies is over 80%. In the Major League Baseball (MLB), free agents have the lowest contract restrictions and teams have often significantly increased their game winning records because of free agents. The objective of this study is to perform professional team player portfolio analyses using the optimization theory to identify the most salary efficient player combinations under the same performance levels and provide the condition setting options such as player selection, parameters, or game play frequency as required by the users. The mathematical model's rapid calculation feature is adopted to provide references for specific team evaluation requirements and contract lists. In addition, this study will also perform sensitivity analysis for the key parameters and use the parameter changes and impacts to provide references for strategy assessment.
