Research on Reengineering and Rationality of Management Process of Farmland Based on Grid

With Yanzhou District in Jining City of Shandong Province as the case, this study discussed the necessity and feasibility of grid management of farmland from the perspective of social service and management against the backdrop that a new management idea is urgently needed due to many drawbacks of traditional farmland management. Based on the current situation about grid management of villages and towns communities in the study area, the grid management process of farmland was explored according to the characteristics of farmland management. To reduce the execution errors caused by the structural errors of the model and the waste of running costs induced thereout, the workflow technology was introduced according to the characteristics of the farmland management process, and the Petri net was used to model the grid management process of farmland and verify the rationality. Exploring various anomalies that may exist in the process theoretically guarantee the normal operation of the grid management of farmland system in the later period, making up for the absence of researches on verifying the rationality of the grid management process. The new structural verification method combining the Petri net simplification technology and the logic table proposed in this study can effectively reduce the workload of verification and analysis. It is applicable to not only simple workflow models, but also complex ones; it is suitable for the rationality verification of models in the domain of grid management domain as well as workflow models in other fields.
