Description
Public facility layout optimization method based on artificial intelligence Technical Field The invention relates to the technical field of artificial intelligence, in particular to a public facility layout optimization method based on artificial intelligence. Background Under the background of new urban and smart city construction, the public facility layout optimization method based on artificial intelligence has become a key technology for improving city operation efficiency, promoting resource fair allocation and enhancing public service quality. Because public facility layout relates to cooperation of multidimensional complex elements such as population distribution, traffic network, land utilization, environmental bearing, social fairness and the like, the planning scheme directly influences the living convenience of residents and the sustainable development of cities. Although the existing digital planning tool supports basic geographic information system analysis and simple optimization models, the existing digital planning tool focuses on single targets or limited constraints, and has insufficient fusion capability on multi-source space-time data, dynamic optimization under complex constraints and real-time integration capability of public participation feedback, so that efficient, fair and practical automatic layout recommendation is difficult to realize in actual city planning. Therefore, there is a need for an artificial intelligence-based public facility layout optimization method that can integrate multi-objective reinforcement learning, and achieve accurate prediction of multi-scale requirements, autonomous optimization of multiple constraints, and overall trade-off of social benefits and operation costs. The patent publication No. CN114821816A discloses a gymnastic place layout optimization method based on artificial intelligence, which comprises the steps of carrying out target tracking on each user entering a gymnastic place to obtain an activity track of the user, determining a stay position and stay time of the user according to the activity track to obtain the gymnastic intention of the user, counting the gymnastic intention of all users in a fixed time period, obtaining a reference using time length of the gymnastic facility according to the gymnastic intention of all users and the corresponding theoretical gymnastic time length of different types of gymnastics, obtaining a using time length of each gymnastic facility in the fixed time length, obtaining a first heat of each gymnastic facility through a difference value between the using time length and the corresponding reference using time length, obtaining an interesting area of each track point in the activity track of each user, selecting the gymnastic facility of the same type as the user in each interesting area, obtaining a reference using time length according to the using information, the number of the user waiting nearby, the latest gymnastic facility of different types and the theoretical gymnastic time length of the corresponding gymnastic facility, obtaining a real heat vector through the layout parameter, and optimizing the first heat vector of each gymnastic facility. Therefore, the gymnasium layout optimization method based on the artificial intelligence has the problem that the space-requirement adaptation degree of the public facility layout is insufficient due to the fact that local historical behavior data and a single heat balance target are depended on and multi-dimensional space-time constraint and dynamic requirement change are not fully fused. Disclosure of Invention Therefore, the invention provides an artificial intelligence-based public facility layout optimization method, which is used for solving the problem that the space-requirement adaptation degree of the public facility layout is insufficient due to the fact that local historical behavior data and a single heat balance target are depended on and multi-dimensional space-time constraint and dynamic requirement change are not fully fused in the prior art. In order to achieve the above object, the present invention provides an artificial intelligence based public facility layout optimization method, comprising: collecting basic data of public facility layout, sequentially performing cleaning, denoising, reformatting reduction and feature extraction on the basic data to obtain layout basic features, and mapping the public facility layout into a layout state vector according to the layout basic features; Training an initial model by combining user requirements and the layout state vector to obtain an intelligent layout optimization model, and analyzing basic data of the public facility layout according to the intelligent layout optimization model to output a layout optimization scheme; Acquiring actual service quantity of public facilities and design capacity of the public facilities, and determining utilization rate of the public facilities in unit time ba
