支持复用和过程改进的过程模型RSDDM

A PROCESS MODEL SUPPORTING REUSE AND PROCESS IMPROVEMENT

当前的软件开发有两个重要特点 :开发过程中的许多活动并行进行且各种软件制品大量复用。另外 ,持续不断的过程改进贯穿软件过程的始终。本文提出的RSDDM软件过程模型基于Petri网 ,能有效描述活动的并行。RSDDM模型还体现了尽量复用的思想 :每个活动的产品尽量复用 ,软件过程本身也是可复用的。另外 ,在RSDDM模型中 ,过程改进贯穿软件过程或软件子过程的始终。

There are two outstanding characteristic in modern software development.On the one hand,many concurrent activities arise during software development process.On the other hand,many software products are reused.Furthermore,it is important to improve process during development.RSDDM(Reusable Systeg Dynamie Development Model) is provided in this paper.The model in this paper based on Petri net,has advantages in des￣cribing concurrent process.The model embodies the idea that it is important to try our best to reuse all software products,even including software process.The model integrates software process improvement technology and software process into a whole.
