Research On Evaluation And Decision Model Of User Centered Stereo Parking System Design

The design and development of the stereo parking system is a comprehensive system engineering including many factors,such as functional requirements,manufacturing technology,user operating comfort,environmental friendliness and so on.However,the design of stereo parking system in the current market is mainly product-centric and functional realization as the goal,which does not fully meet the requirements of users,and the design concept lags behind the development needs of the times.Therefore,it is necessary to change the design concept from product centered to user centered.In addition to considering the basic functional elements of the stereo parking system,it should be studied how to fully meet the needs of user groups and coordinate the system relationship between human,machine and environment,and carry out the design and development of the stereo parking system.Focusing on the evaluation and decision-making model of the stereo parking system design,this paper studies from the following aspects:Firstly,the research process of the evaluation and decision-making of the user-centered stereo parking system design scheme is proposed.Combined with modern human factors measurement methods,mathematical statistics,computer virtual simulation and other theories and tools,this paper analyzes the research process of stereo parking system evaluation and decision-making,and summarizes the key factors affecting stereo parking system evaluation and decision-making with the subjective and objective conditions of user needs and manmachine environment system coordination.Secondly,the user's comfortable degree evaluation model of the users and environment of stereo parking system is established.Combined with a variety of research and professional measurement tools,the quantitative research is carried out on various environmental parameters,users' physiological perception and psychological feeling.The key factors and their relationship are analyzed that affecting the user's comfortable degree evaluation of the stereo parking system environment.Thirdly,it extracts the key factors affecting the design of stereo parking system of users' physiological perception and operation experience,and analyzes the relationship between them.Combined with EEG test technology and user behavior analysis,it discusses the key factors affecting the design of stereo parking system and user perception evaluation and their relationship,analyzes the changes of user perception physiological perception and psychological cognitive load,and summarizes the design principles.Fourthly,the spatial layout and planning model of the stereo parking system is established.Combined with the theory of design science of human affairs and intelligent object image technology,it extracts the key factors that affecting the planning of the stereo parking system,user operation experience and efficiency,from the rationality and suitability of parking space layout.It analyzes the subjective and objective factors of affecting user behavior and environment,and verifies the model with specific cases.Fifthly,an evaluation decision-making model based on the combination of analytic hierarchy process and cooperative game is established.User centered design needs to meet the group needs of various users on the basis of man-machine environment coordination.The user groups related to stereo parking system are classified,and the analytic hierarchy process is applied to analyze and compare the weight of the key factors affecting the demand of user groups.With the cooperative game theory,compromise weights are set for the needs of different user groups,and a multi type user demand combination weighting and evaluation decision-making model is proposed.The model is verified by virtual simulation platform and case application.
