摘      要：In crop production systems,all operations such as seed bed preparation,etc.,must be accomplished on time,if yield reduction and low quality product are to be *** all operations in mechanized cropping projects require precise scheduling,planning and *** basic approach in all scheduling techniques is to form a network of activities and events relationships that graphically portrays the sequential relations between the tasks in a *** a network would as a powerful tool available a farm manager to plan,schedule,monitor and control a *** GERT（Graphical Evaluation and Review Technique） networks have most of advantages associated with networks and available system analyst in exact evaluation of certain types of networks,in this research it was used and mechanized wheat production system was simulated,modeled and *** activities,events and path were *** showed that the network model was able to answer any statistic questions concerning with the *** models,particularly GERT networks are increasingly powerful tool for modeling,scheduling,planning,controlling,and analyzing of agricultural mechanization projects.
