模糊多目標非線性規劃模式於多專案排程與碳排放成本效能之應用

碳排放法規已成為當今控制企業碳排放量的重要機制。為符合法規的要求企業必須在生產規劃決策上進行改變。本研究之目的乃在提出一個模糊多目標非線性規劃模式，以進行多專案排程與碳排放成本效能之分析。本模式可同時處理均衡考慮包括提升專案淨現值、節省碳排放成本以及增加專案總寬裕時間等多個目標的排程計畫。本研究也導入決策滿意度函數作為專案經理進行多目標規劃時的績效評估分析之使用。本研究也進行數值範例分析與說明。研究結果顯示本研究所提出的模式可協助專案經理同時獲致總專案淨現值及總寬裕時間最適化的排程結果。

Carbon emission regulation policies have emerged as mechanisms to control firms’ carbon emissions. To meet regulatory requirements, firms can make changes in their production planning decisions. The purpose of this study is to formulate a fuzzy multi-objective non-linear programming (FMONLP) model to analysis the cost-effectiveness for multi-project scheduling and carbon emissions. The model is capable of quantitatively solving multiple problems including project net present value increase, carbon emissions cost saving, and project slack time increase to obtain a balanced multi-project scheduling scheme using a multi-objective non-linear programming technique. An optimal satisfactory level is deployed to demonstrate the trade-offs among fuzzy multi-objectives for the use of project managers. Numerical examples are presented, and results are discussed. The results showed that the developed model could be found useful by mangers who wish to jointly maximize the project net present value and total slack time.
