Simulation implementation method and system for urban logistics operation environment

Abstract

The invention discloses a simulation implementation method and system for an urban logistics operation environment. The method comprises three steps of basic information acquisition, data processing and operation environment simulation. Simulation of three different urban logistics operation environments including a certain type, a customer demand uncertain type and a vehicle passing time uncertain type is realized through collection of geographical related information, customer demand related information, vehicle related information and freight traffic management policy related information and processing of urban road network information, customer demand information and vehicle information. According to the method, the urban logistics operation environment is comprehensively and truly simulated, a plurality of examples considering different urban logistics operation environments are generated, and rich and reliable research data can be provided for optimizing urban logistics operation and scientifically formulating freight traffic management policies.

Description

technical field [0001] The invention belongs to the technical field of logistics system simulation, and in particular relates to a method and system for realizing simulation of an urban logistics operation environment. Background technique [0002] Cities are the main concentration places of production and life, and also the places where logistics activities are most concentrated. As a feasible urban logistics solution, a two-layer logistics network is being adopted by many large and medium-sized cities at home and abroad. How to optimize the urban logistics operation of the two-layer network structure (such as minimizing logistics costs, minimizing vehicle carbon emissions, etc.), and how to evaluate the impact of current freight traffic management policies on urban logistics operations have become urgent tasks. [0003] Carrying out urban logistics operation optimization and freight traffic management policy evaluation research requires a large amount of data. However, the...

Problems solved by technology

[0003] Carrying out urban logistics operation optimization and freight traffic management policy evaluation research requires a large amount of data. However, there is no simulation research on the urban logistics operation environment with a two-layer network structure at home and abroad. Most of the data in the literature does not come from the real simulation of the urban logistics operation environment, making it difficult for most research conclusions to be verified and put into practice
