The Research On Applicability Evaluation Of Urban Underground Logistics System Construction

With the development of economy,the problems about the traffic jams,environmental pollution and energy consumption of the city have been more and more serious.The development of economy has led to the rapid growth of the amount of logistics distribution and frequency.Due to the restriction of urban road capacity and logistics system transportation capacity,the contradiction between supply and demand is highlighted.To solve the corresponding problem,the urban underground logistics system that the freight transportation is transferred to the underground has become a new method.Focusing on the research about the applicability of construction of the urban underground logistics system is to provide the basis for the development and implementation of the urban underground logistics system.Aiming to analyze the influencing factors of the construction of urban under-ground logistics system,the applicability indicator system of the construction of the urban underground logistics is constructed.Then,the multi-factor loop filtering model is established and corresponding algorithm is designed:Firstly,the domestic and foreign research results of underground logistics system are systematically analyzed.The existing underground logistics system,whose feasibility and development status are summarized.And the gap in the applicability evaluation of urban underground logistics systems is analyzed.The theoretical justification is provided by these.Secondly,the influencing factors of urban underground logistics system construction were analyzed,and a set of primary indicators is constructed according to certain principles.With the comparison of conventional filtering methods,a multi-factor loop filtering model based on the importance and correlation of indicators is constructed to filter primary indicators.On this basis,the order-cloud model is proposed to evaluate the applicability of urban underground logistics system construction.Finally,the evaluation indicator system for the construction of urban underground logistics system is constructed.Furth more,the status of Shanghai city is taken as a case to be evaluated.The evaluation results are consistent with the facts,so the feasibility and rationality of the multi-factor loop filtering model and indicator system has been verified.The evaluation indicator system of the construction applicability of urban underground logistics system constructed has certain reference value in the theoretical research of urban underground logistics system,which can provide theoretical support for the construction of urban underground logistics system in the future.The multi-factor loop filtering model based on the importance and correlation of indicators is proposed and implemented by the corresponding algorithm,which provides a new direction for future indicator filtering.
