Evaluation Of Road Transportation Efficiency Based On Fuzzy Double Frontiers Network Model

Road transportation is one of the five major transportation methods,and its system operation efficiency is related to government planning,industry development,corporate operation,and multiple levels of individual needs.Road transportation efficiency is an important index to measure the development level of national and regional transportation.In order to improve the service level of transportation industry,accelerate the reform of supply side structure and promote the sustainable development of China’s economy,it is necessary to evaluate the efficiency of each stage and put forward suggestions.Under the strategic background of building a transportation power in China,evaluating the efficiency of road transportation and matching the transportation resources with the increasing demand for passenger and freight transportation is of great significance to grasp the current situation of road transportation development and promote the efficiency upgrading of road transportation services.Data Envelopment Analysis is an objective method of research efficiency evaluation issues in economic activities.In recent years,scholars have begun to steady their internal network structures.In order to more comprehensive,objective,flexible evaluation of road transport efficiency,this paper proposes a new transportation efficiency evaluation method to divide the road transportation process into infrastructure construction,passenger and delivery main body and transport performance assessment three Some,in this case,the influence of nondesired output and index uncertainty in efficiency is considered,and the road transport efficiency evaluation method based on fuzzy bilateral network data envelope model is proposed.Since the interval secondary blur variable describes the uncertain data in reality,such as energy,funds,cargo tonnage,etc.,and uses a key value to decrease,and the α-cut method transforms fuzzy data to precise data;effective according to the indicator characteristics and decision-making unit Sexual relationship,indicator selection principle,etc.Establishes road transport efficiency evaluation index system;based on road transportation three-layer network structure,constructs an envelope model based on two cases based on invalid boundaries,the model highlights invalid decision-making unit in efficiency evaluation The role in avoiding multiple decision units are effective,and can flexibly monitor changes in internal sub-process efficiency in the inaccurate system.The transport efficiency value changes as the input output value changes,but the fuzzy number upper and lower limits can determine two special efficiency values,thus maximizing the maximization of the model,and the model is maximized the efficiency of the decision unit.The variation range of the efficiency of decision making units.In addition,this paper also analyzes the effects of intermediate output indicators to subprocess efficiency,establishing sensitivity analysis methods,determining the ability of the system to maintain its efficiency classification without changing the link variable.Finally,after the rank and inspection have proved the reliability of the model,take the Sensitivity from Jilin Province,from the different boundary efficiency,efficiency variation,three sub-process efficiency and efficiency for external indicators,internal indicators change,multiple aspects The development trend of road transportation within 20 years is evaluated to the road transport efficiency of Jilin Province.
