中文摘要 | 對任何一個軟體系統而言,「軟體成本」關係整個計畫的發展方向、設備及人員之有效調度,發展一套系統化軟體成本估算方法有其必要性,因此「軟體成本分析之研究」著實為軟體發展之一重要步驟。本研究係以統計學理論為基礎,配合Barry W. Boehm所提出之COCOMO模式,進行分析工作。為確實符合我電信軟體之本質特性,所有相關資料均由各局所軟體發展單位所提供。 本文就可能影響軟體成本之因素,蒐集35份軟體系統資料,在COCOMO模式下加以評估,發現該模式並不全然適用於我們的環境,於是根據所蒐集之資料進行統計分析而提出一成本估算修正模式(TL Cost Model)。為了提高修正模式之精確度,我們刪除異常資料,並利用迴歸分析去隱其中不顯著之成本因素,且調整影響因素權數,而得一套適合我電信軟體環境之成本估算模式。同時為證明此模式之實用性,我們以「電信總局軟體發程序規範」試用計畫所搜集的10組資料加以驗證,結果相當理想。 本研究已為我電信軟體建立一套軟體成本模式的分析方法,根據分析成本進而建立電信軟體之軟體成本估算制度是我們下年度研究目標。 |
英文摘要 | For any software system, “software cost” determines what the whole project would emphasize as well as how effectively the equipment and personnel would be managed. Therefore, a study in “software cost analysis”, which helps us to develop a systemized method to estimate software cost, is thus essential to the development of the telecommunication software. This analysis is based on statistical theories in accordance with the COCOMO Model proposed by Barry W. Boehm. All related data are provided by the software development department of bureau so as to precisely correspond to the characteristics of telecommunication software. In this paper, we collected 35 software system data which would possibly affect the software cost. Aftere valuating the data under the COCOMO model, we found that the model did not completely apply to the telecommunication environment. Thus we propose a modified TL Cost Model by analyzing again all the collected data with statistical theories. To enhance the precision of the modified model. We deleted singular data, expunged insignificant elements with regressive analysis, adjuste4d the weighting coefficient for each factor and finally we derived a cost estimation model that best fitted the telecommunication environment. Meanwhile, to ascertain the practicality of the TL Cost Model, we tested it on 10 trial projects of “DGT Software Development Guide.” The result is quite satisfying. This research has established an analytical method for the estimation of telecommunication software cost. It will bring forth an estimation system into goal of next year. |
