在高度競爭的軟體市場中，如何維持市場競爭力是每間軟體公司都必須面對的重大課題。當一間軟體公司能夠善用軟體發行管理時，它能夠最大化地滿足目標客群的需求，進而達到市場佔有率之最佳化的目標。在進行軟體發行管理時，軟體公司需要對目標客群的需求排定優先順序，並基於多方考量選擇最佳的軟體發行方案。許多需求排序的技術利用加權法 (Weighted sum model) 的方式，先計算目標客群對發行方案之滿意度或需求程度的加權總分，再基於發行方案的加權總分排定其優先順序。然而，加權法並未針對軟體發行管理中的兩大重要議題提供解決辦法。第一、各項產品的最終發行方案應該使該產品所指向之每一類目標客戶都感到滿意。第二、應避免各項產品之間產生非預期的內部競爭。當一間軟體公司為了加速軟體的推出而採用軟體生產線的作法開發軟體時，這兩項議題將變得愈發嚴峻。由於軟體生產線是透過大量的軟體重用以降低開發的成本及時間，此作法之下開發出的產品，相較於其他作法，更容易導致產品之間的高度相似性。故軟體公司需要透過適當的軟體發行管理，才能讓軟體生產線的作法發揮最大的效果。針對上述兩項議題，本論文以加權法為基礎，透過結合個別顧客滿意度，提出一套新模型以應用於需求排序的技術中。文中更利用三個真實個案驗證此新模型之有效性。驗證結果顯示，透過此新模型篩選出來的軟體發行方案，除了能夠使各產品指向之目標客戶群感到滿意，亦能避免公司內部產品之間的非預期競爭關係。

Satisfying target customer needs the most to optimize market share with proper release management is critical for keeping the competitiveness of software companies. Many requirements prioritization techniques, which support release management, use the weighted sum model (WSM) to deal with customer satisfaction. However, the WSM does not address two important issues in release management. The first issue is that each product should satisfy every target customer of the product. The second issue lies in avoiding unexpected competition between products. These two issues are especially severe when software companies adopt software product line practices to support software reuse. While software product line practices significantly reduce the development cost and time, the high similarity between products due to software reuse increases the complexity of release management. To resolve these two issues, this thesis proposes a model that combines the WSM and individual customer satisfaction. The model is evaluated through three real-world case studies. The results show that the model identifies all release plans that not only satisfy every target customer within a product but also avoid unexpected competition between products.
