Research On GERT Network Model Of Dairy Industry Quality Chain For Multidepartment Cogovernance

The government attaches great importance to the dairy industry.The dairy industry is a basic industry related to the national economy and people's livelihood.Since the outbreak of the melamine incident,the country has adopted a number of important policies: "Dairy Quality and Safety Supervision and Administration Regulations","Dairy Industry Reorganization and Revitalization Plan Outline" The multi-sector co-governance model of the dairy industry has gradually taken shape.Under the multi-sectoral co-governance model of the dairy industry,the quality decision-making mode of each link in the dairy industry will be different from the previous industry decision-making mode.How to analyze the quality decision-making behavior of the dairy industry under the multi-sector co-governance model,and how to analyze the formulation of industry regulatory policies under the multi-sector co-governance model has become the key to improving the quality of the dairy industry and promoting the healthy development of the dairy industry.Therefore,based on the GERT network model,this article builds a decision model that can reflect the relationship between government regulatory decisions and dairy industry quality decisions,in order to explore a scientific and reasonable analysis method to provide analytical methods for dairy industry quality decisions and to formulate related policies.Provide theoretical basis.The main contents include:Firstly,consider the situation of quality decision-making in the dairy industry without government supervision,analyze the network relationship of quality decision-making in the dairy industry,construct a dairy industry quality chain network model based on the GERT network,and design to measure the economic value and quality value of the dairy industry.Comprehensive indicators,through simulation experiments and sensitivity tests,analyzed the quality decision-making behavior of each node in the quality chain network model of the dairy industry,and found that the changes in the quality decision-making behavior of the quality chain entities of different dairy industries have different effects on the economic development of the dairy industry.And put forward relevant suggestions on quality decision-making in the dairy industry.Secondly,considering the situation of quality decision-making in the dairy industry under a single government supervision mode,the network relationship of quality decision-making in the dairy industry under the single government supervision mode is analyzed,and a GERT network model for the quality chain of the dairy industry under single government supervision is constructed.The economic value,quality value and industry stability of the product industry are comprehensive indicators.Through simulation experiments and sensitivity tests,it is found that a single government supervision behavior has a significant impact on the quality decision-making of the main body of the quality chain of the dairy product industry.Recommendations on decision-making and government supervision.Finally,considering the situation of quality decision-making in the dairy industry under the multi-sector co-governance model,it analyzes the transfer of regulatory information and regulatory behavior in government supervision and the conversion relationship between economic value and quality value in the dairy industry,and constructs a multi-sector co-governance model The GERT network model of the quality chain of the dairy industry under multi-layer government supervision has designed comprehensive indicators to measure the economic value,quality value and government supervision performance of the dairy industry.Through simulation experiments and sensitivity tests,the analysis found that the quality of the dairy industry in multi-layer government supervision Government supervision information and supervision behavior in the chain network have a significant impact on the quality decision-making of the main body of the quality chain of the dairy industry,and put forward relevant suggestions on the quality decision-making of the dairy industry and government supervision behavior.
