The invention provides a smart pre-diagnosis and health management system modeling method, which comprises a new tree establishing step, a dual-branch modeling step, and a model self-adaptation optimization step, which can be modeled by a dual branch with the increase of monitoring data. The proposed prediction hypothesis model selects the best solution as the benchmark for the optimal decision, which is used for the next forecast and makes the system's prediction result meet the expected target value. The invention also provides a computer program product of a smart pre-diagnosis and health management system, which performs the above-mentioned intelligent pre-diagnosis and health management system modeling method when executing the computer program product.本發明提供一種智慧型預診斷與健康管理系統建模方法,該方法包括新樹建立步驟、雙分支建模步驟、以及模型自適性優化步驟,可隨著監控資料的增加以由雙分支建模步驟所建構出的預測假說模型中挑選出最佳方案做為最佳化決策的基準,此基準為下一次預測使用,並令系統的預測結果符合預期目標值。本發明同時提供一種智慧型預診斷與健康管理系統的電腦程式產品,令執行該電腦程式產品時完成上述的智慧型預診斷與健康管理系統建模方法。
