Research On Layout Optimization Of Railway Logistics Park Based On Operational Streamline Organization

Railway logistics park is an important logistics node in the region,It has the characteristics of large scale,large investment and long construction period.Scientific and rational planning of railway logistics park is of great significance for realizing the overall benefit of the park and giving full play to its functions effectively.However,in the planning process of railway logistics park layout at the present stage,there will be problems such as unreasonable layout,chaotic traffic organization and inefficient operation.In view of this situation,the main research contents of this paper are introduced.Firstly,through the analysis of the relationship and difference between Railway Logistics Park and traditional railway freight yard,summarized the characteristics and main functions of railway logistics park.On this basis,put forward the basic form and method of railway logistics park layout.At the same time,introduce the related theory of work streamline.The characteristics and functions of work streamline are sorted out and analyzed.Put forward the layout form of logistics park based on operation flow line.Secondly,According to the characteristics of Railway Logistics Park,analyze the traffic system of railway logistics park,put forward the business process of railway logistics park.On the basis of this business process,the operation flow line of railway logistics park is drawn,and design the basic flow direction and space form of operation flow line.Lastly,combining the Interrelation of functional intervals,establish the layout optimization model of railway logistics park,and obtain the layout scheme that follows the spatial form of operation streamline.Consider the restrictive factors such as park scope,aspect ratio,relative location,etc.The LINGO optimization software is used to solve and obtain the results,and the rationality and applicability of the relevant theoretical methods are verified in practical cases.
