First , the paper analyzes four basic view pictures , and build up a product - developing - project system , which can be decomposed into a " project - tree " in the upright direction and has " workflow - networks " in the horizonal direction , with its life cycle and management work . then the paper studies the methods of decomposing the " project - tree " and designing the " workflow - network " . finally , the paper studies how to develope such a pdpm infomation system and designs it , and compares the traits of different software srurctures and the new web services technology by the way 本文首先分析了項目管理的四個基本視圖,在此基礎(chǔ)上建立了“縱向分解成項目樹、橫向具有工作流”的產(chǎn)品開發(fā)項目體系,并描述了項目管理的生命周期和管理功能,然后重點探討了項目管理兩個主要功能? ?縱向項目樹分解、橫向工作流規(guī)劃的方法或算法,最后選擇基于web的多層體系結(jié)構(gòu)和支持webservices組件技術(shù)的。
