The Modeling of Dual Drive Software Based on Requirement and Runtime Variability
Zhigang Liu, Lei Shi, Zhen Ge, Xiaozhi Wang · 2016
In order to solve the operating environment of the dynamic evolution, this paper builds the internal reflection of the SaaS evolution model describing according to the needs and variability of the software dynamic evolution, the model is the formal definition by using communication process algebra (ACP) as the main form, and each piece uses ACP to describe a process item.On this basis, based on cloud computing dynamic environment, this paper studies effective prediction software requirements and change sensitivity method in software process, and taking the requirements and operational variability for dual drive model establishes PAAS software dynamic evolution platform.Finally, this paper carries out improvement for the software process, the use of the Petri net and ACP verify the improvement process, and the improvement results are evaluated and packaged.
