Abstract
With the increasing demand for food worldwide, it has attracted increasing attention how to improve the agricultural production efficiency. This paper aims to develop a technical efficiency evaluation system for vegetable production to provided decisions for the practice of precision agriculture. The paper analyses the system-needs and business processes, and proposes a system framework which has three tiers architectures, based on B/S model. The stochastic frontier analysis (SFA) algorithm model which is the incorporated into the system is established. The system was tested and evaluated by real business data, which were from Beijing from 2003 to 2011 to test system performance based on the temporal perspective and China during 2011 and 2012 to test system performance based on the spatial characteristics. The results shows that the system achieves the business requirements with an intelligent tool for data management and technical efficiency evaluation for vegetable production to improve automation, efficiency and convenience.
