Inner Facility Layout Optimization Based On Streamline Analysis For Passenger Terminal

The main purpose of passenger terminals in the architectural design and layout planning is to solve the problems of terminals function and architectural aesthetics and so on through the terminal's plane and space system design integratedly. The primary purpose is to achieve the functions of the terminals. the important factors which affected the Terminals functions . flow lines,is the focus of passenger terminals design. Study on simple, reasonable, smooth passenger flow line is a primary task and a prerequisite for the terminals architectural design and facilities layout. How to achieve the requirements of both pedestrian flow lines and the facility layout and optimization of control is one of the important contents of integrated passenger terminals planning and design theory.At present, the majority research results of flow.line analysis are analyzed the relationship between the flow line and architectural space layout from a view of qualitative point, such as the impact of flow line analysis to facility layout and the facility layout effect flow line oriented. It's supposed to seek effective ways of a combination of quantitative and qualitative to meet the requirements of pedestrian flow lines and to achieve the facility layout optimal control program at the same time. For this reason, this paper was studied in terminals facility layout and optimization of internal control based on the analysis of passenger flow line.The paper consists of six chapters, which are as follows:Chapter I, Introduction, summarizes the current situation of the research on flow line analysis and facilities layout of domestic and foreign, elaborates the necessity of the study on terminals facility layout and optimization of internal control based on the analysis of passenger flow line. Propose technical line and the primary coverage of this paper.Chapter II, outlines the theory of flow analysis, that is proposed logical framework analysis and theoretical methods by integrating existing research. According the goal of streamline analysis, we carried out the passenger terminals'region, statistics the number of streamlines in different region, the analysis the raw of streamlines static distribution. According to the regional terminals for the existence of different functions within the various movements of the passenger, we examine the region situation which was occupied by the various streamlines. According to the classification of the streamlines in Passenger terminals, we can generate streamlines in accordance with the established layout, identify bottleneck regions in the passenger terminals, and analysis the causes of bottlenecks in the region, according to the causes, we use two methods of eliminating bottlenecks region to optimize the bottleneck regions.Chapter III, Research on the SLP improve method based on the analysis of flow.line. On the premise of the theoretical methods of analysis of flow.line, combined with the theory results of the system layout design , Proposes improve method (SLP)based on the analysis of flow.line, which improved from three aspects, parametric switch, steps switch, importation of computer simulation technique; then, establish the optimization model of facilities layout, that is consider the total utility model through security,functional,structure effectiveness integrated. The improve control method witch focus on facility layout design phase and improve phase are given separately.Chapter IV, the realization of the improve SLP method simulation, combined with flow line analysis and optimization model of facility layout; give the way of how to achieve the simulation link of improved SLP method. The system simulation model of the object was established on the boundary of the terminals entrance based on pedestrian streamlines. The simulation model put into the existing layout of facilities, as streamlines simulation environment; achieve the dynamic simulation of flow lines of pedestrian get in, get out, transfer of three different lines, including the starting point, destination, as well as various facilities node on the way. Adjust the master parametric of Facility Layout Optimal model based on Facility Layout Optimization control strategy, and extract relevant parameters of Facility Layout Facility Optimal model through the operation and the analysis of system simulation results, offer a reliable basis for the optimization strategy.Chapter V, case studies, the correction was verified of Facility Layout Optimal model based on flow line analysis by studing Xizhimen subway transfer terminals case, at the same time the effectiveness of the facilities layout optimization control strategy was verified; and by comparing the implementation effect of different organizations program of the actual terminals operation, propose the optimum project, offer rationalization proposal for optimal control of the facilities layout of passenger transport terminals.Chapter VI, Conclusion and outlook, the research results and what need further research of this paper was summarized.The main results achieved in this paper:⑴proposed logical framework analysis and theoretical methods of pedestrian terminal flow line analysis which make s conclusion of flow line analysis thoughts; describe detailed processes and basic steps of terminals internal flow line, provide a fairly complete guidance framework structure for all types of terminals internal flow line analysis, has great practical significance.⑵the streamline analysis was based on to combining the static analysis methods of transport infrastructure planning and design the methods of flow lines analysis and facilities arrangements SLP method, with system simulation technology, Proposes improve method based on pedestrian terminal facility arrangement flow.line analysis。The method belongs to QAP problem essentially, because the method make the results of streamline analysis, that is, the facility relative relationship and position after the formation of eliminating bottlenecks in the flow line, to be the input data of improved SLP ways, to make some uncertainty facilities structure to be determinate, thus, make the facility layout optimization model . the largest total utility of facilities layout as the biggest targets for the secondary distribution, reduced the difficulty of the solution greatly, make the method suitable for application in the practice of passenger terminals planning and design. At the same time, the dynamic hosts of configuration parameters by system simulation technology in the implementation step of improve SLP method, enabling the dynamic parameters chose and simulation optimized of facility layout strategy, solve the problems of the lacking facilities layout analysis method and simulation experimental technology of passenger terminals facility layout.
