The Study And Implementation Of FVS Architecture Using Multi-Agent And Plugin

To better guide the management and operation of Chinese forestry, mature forestry vegetation simulation software should be introduced from abroad. This article described the practice of the localization of Forest Vegetation Simulator (FVS) from America to China, the main purpose to which is to discover a way to reengineer a large-scale legacy system, and to apply new methods of design to the target system. After researching, the author decided to introduce Agent method which can guide our entire reengineering procedure, and also parallel iteration method which can significantly reduce the life cycle, guarantee the success of each period of reengineering. This approach worked well for us. The new FVS system had new feathers after the reengineering, such as:dynamically parsing the calculation expression in the forestry models, so that modifications of models get much easier than before; more reasonable division of components and modules within the system, and the support for plug-in for the future improvement. Furthermore, this thesis optimized the architecture of the FVS system and made it more scalable, in a way that plug-in can be better supported. Under cross reference, the localization end up well as expected. This also verified that the method of reengineering based on Agent is doable and superior.
