面對日益激烈的競爭環境，有效的衡量企業經營績效，進而找出提高營運績效的具體方向已是不容忽視的課題。事實上，在進行企業經營績效評估時，需考慮多個構面及影響因素，以及評估人員的主觀性判斷，才能完整且全面地呈現企業的經營績效狀況。本研究應用平衡計分卡的財務、顧客、內部流程、學習與成長等四大構面為基礎，進行多面向企業績效評估系統的規劃與建置。然而企業績效的評估過程中，評估者常因評估指標的質化特性及主觀感受，而不易利用明確值表達其評估值，使得績效衡量過程與結果，容易產生模糊性及不定性。為此，本研究乃結合二元區間語意變數及平衡計分卡，規劃一個多面向的企業經營績效評估系統，以協助企業快速且有效地進行經營績效的評估，以掌握經營績效的改善方向。
