COTSYS Cotton Cultivational Simulation and Decision making System
Feng Li · 1999
Cotton cultivational simulation and decision making system (COTSYS) was completed by our research team after more than seven years efforts since 1992. The system was developed on the basis of field experiments and information from production demonstrations by integrating the experience of high yield production, experts' experiences and knowledge, the crop simulation and optimum cultivational decision making and the theories and means of AI. COTSYS consists of five main functional subsystems: database management, simulation and analysis, cultivational decision making, control of diseases and pests , economic profit analysis. This system can be applied for the follow purposes: the optimum decision making for normal or current year's cotton production in cotton areas or specific sites, the making of cotton cultivational decision chart and rules, the analysis of cotton potential production and simulation and prediction of cotton growth and yield formation, the adjustment of parameters, management of database and weather data generation, the control of diseases and pests and the analysis of economic profits, etc.. It is adapted for the computer aided management and decision making of cotton production for early, mid early and mid materity cotton areas in China. In 1994, the results showed that the yield guided by COTSYS was increased by 19 3%, In 1995, increased by 23 4%. Moreover, it is obviously showed that the rate of output and input also increased.
