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 avoided. Therefore all operations in mechanized cropping projects require precise scheduling, planning and management. The 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 project. Such a network would as a powerful tool available a farm manager to plan, schedule, monitor and control a project. Since 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 analyzed. Critical activities, events and path were determined. Results showed that the network model was able to answer any statistic questions concerning with the project. Network models, particularly GERT networks are increasingly powerful tool for modeling, scheduling, planning, controlling, and analyzing of agricultural mechanization projects.
