本論文之主要貢獻為 : (1) PM-Net改進了PERT、CPM、DesignNet必
須俟所有前工作項目完成，才能啟動後工作項目之限制。 (2) PM-
Net透過由下而上(Bottom-up)的資料蒐集，使軟體專案進度現況資訊的顯
示能夠精細到每一個細小的工作項目，也可以大到最上層的工作項目，因
此管理者可以透過PM-Net, 隨時依據其個人職責上的需要，瞭解其所關切
部份的專案最新進度變化動態。 (3) 當使用者規格或設計規格異動
時，PM-Net可自動顯示那些已完成的工作項目必須被重新執行，那些正在
執行的工作項目必須暫停，亦即PM-Net可迅速提供資訊，協助管理者靈活
調度人力。 (4) PM-Net模式與傳統模式之整合, 則使PM-Net無法顯
示時間量度，及管理者無法迅速掌握各工作項目上下層關係的管理缺失獲
得解決, 同時它擴展了PERT、Gantt及WBS模式應用於專案管理上的深度及
廣度, 使其管理功能得因透過與PM-Net模式相互整合的結果,而獲得有效
的發揮。包括 : A. PERT除可作為專案初期之人力時程規劃用外, 在專案
執行期間可隨時重新建立未完成工作項目之關係, 並多層次顯示其剩餘規
劃時程或重規劃時程。 B. Gantt-Chart可更為正確且詳細地多層次顯示
各工作項目實際執行時程的動態變化,包括每一個大小工作項目之每一個
版次(version)何時開始被執行, 何時暫停, 何時重新被執行及何時完成
等。本論文共分為五章，第一章緒論，主要介紹本論文之研究動機、研究
目的、研究範圍及研究步驟及方法；第二章為文獻回顧，主要探討與研究
問題有關之相關文獻或研究；第三章為PM-Net模式理論研究；第四章為
PM-Net模式與傳統模式之整合應用研究；第五章為結論與建議。

A model called PM-Net for representing and monitoring the
software Development process is presented. This model
provides information for progress management, as well as
information of project status at different levels of detail,
for the benefit of project managers. This model emphasizes
bottom-up data collection and top-down information inquiry
functions. The Data Flow Diagram (DFD) and Work Breakdown
Structure (WBS) techniques are utilized for construction of a
hierarchical structure of the software development process.
This process can be viewed as a set of activities; each
activity can be viewed as a set of subactivities, and
each subactivity can be viewed as a set of tasks. Managers
can make an inquiry regarding project progress information
at process level, activity level, subactivity level or task
level, depending on the degree of details they require . The
manager can also change the control state operators at the
lowest level of activity which will enable a transition for a
change of process status at the upper-level activity. This
ensures that any large -scale software development project
based on PM-Net will be able to represent the most recent
project progress status at any time in the project''s running
duration, so that managers can monitor the project progress
more efficiently. A series of models based on PM-Net for
representing and controlling the software development progress
is presented in chapter 4. There combines the PM-Net and the
traditional management models of PERT, Gantt chart and WBS.
Managers can make an inquiry regarding project progress
information at different levels of detail. This PM-Net series
models can provide the most recent project progress status to
the manager at any time in the project''s running duration. They
can also assistant the manager, to plan and change the project
schedule and manpower in project''s running duration.
