At present, the traditional method of logistics distribution center location is mainly achieved through dynamic planning of location. When the scale of the problem is large, it is easy to produce large deviation, and the optimization effect is not ideal. For this reason, a method design of logistics distribution center location based on particle swarm optimization is proposed. This method effectively improves the learning factor and location formula of particle swarm optimization, and establishes a mathematical model of logistics distribution center location. The experimental results show that the proposed method has higher convergence and better search ability.

This paper builds a decision model for intelligent networked vehicles (ICV) lane changing behavior based on the idea of game theory. Focusing on the complex traffic conditions of three-lane highway with multi-vehicle interaction and competition, we solve the ICV lane change decision problem by pairing ICVs two by two, formulating a multi-group game and comparing the game gain results to find the best. Based on Time-to-Collision (TTC), we design the payoff function of this decision model game so that the game results in a pure strategy Nash equilibrium (PSNE), and obtain the unique optimal lane change decision for a given state by designing the objective function of the lane change game. The joint simulation by PreScan/Simulink/CarSim software verifies the rationality of the payoff function and the validity and applicability of the lane-changing model.

The investment evaluation of power grid construction projects is a necessary link for power grid companies to carry out power grid construction. In the traditional evaluation process, it is generally based on the original index scores or similar schemes for comparison and decision-making. There are problems of simple methods and insufficient theoretical support. Fully considering various factors in the investment process of power grid construction, a set of rating index system with three-level hierarchical structure is constructed with actual demand as the standard. The evaluation model is verified and analyzed by an example.

Based on the research and analysis of the development status and characteristics of the Hydrogen fuel cell vehicle industry in Jinhua, combined with the domestic and foreign technology development direction and industry development trend, through extensive demand research and the construction of a standard system, this paper guides the technological innovation and standard creation of Hydrogen fuel cell vehicles, and promotes the sustainable, healthy, scientific and orderly development of the industry. In the process of building the Hydrogen fuel cell vehicle standard system, we should do a good job in top-level design, build a good standard system framework, and promote the better development of the entire standard system. After the introduction of various standards, we should popularize and implement them.

Using five objective metrics and eight video sequences, the paper shows that AV1 generally outperforms HEVC in bitrate and quality, but also has higher complexity and lower compatibility. The paper discusses the findings and implications of the study, compares them with the existing literature, and provides some suggestions for future research or practice on 8K video coding.

The integrated guidance and control design of missile considering the attack angle constraint can effectively improve the guidance accuracy and damage effect of the missile, which has become one of the hot spots in current research. In this paper, we review the problem of integrated guidance and control design of missile considering attack angle constraint. First, the steps to construct the ensemble model are described. Second, combining with the fact that modern control theory has been successfully applied to the design of missile weapon systems, the integrated design approach for missile guidance and control in recent years is summarized and summarized in this paper. Finally, the analysis and discussion of the problems and trends that need to be addressed in the integrated design of missile guidance and control can break through the constraints of traditional missile design concepts and methods and serve as a reference for the development of a new generation of missiles.

The article discusses the main safety warning types of power grid for meteorology and ice cover, and elaborates the safety warning strategy of power grid from four perspectives: safety technology dimension, safety strategy dimension, safety guarantee dimension, and building a comprehensive defence system, based on OPA model, CASCADE model, hidden fault model, Manchester model, and optimal tide outage model researched by previous researchers. From the perspective of power grid structure, interface and controller, signal, and control strategy, the author gives the operation control, voltage stabilization control, power control, and islanding control strategies to grid security warning through simulation experiments. Power grid safety and accident prevention prospective and preventive have become important technical means of safety production management. Through the research, the first mothed is to solve the problem that some enterprises are used to mending leaks afterwards, an inspection a blockage, did not play the role of early warning; the second is to solve the problems of equipment conditions backward, lack of special financial support, and early warning mechanism into paper; the third is to solve the lack of effective supervision, which makes the function of crisis information difficult to timely detection, analysis and judgment, even difficult to prevent and pre-control the occurrence of accidents effectively; and the fourth method is to solve the problem of the lack experience for some enterprises in grid accident decision-making and post-accident response, which may lead to the spread of accidents.

Currently, our lives and production heavily rely on electricity. As the number of power users continues to grow, the demand for electricity is also increasing rapidly. In this context, it becomes imperative to enhance our power supply systems in order to meet the surging demand. The implementation of a secondary relay protection loop is vital for ensuring the stability of our power system. However, in practical applications, issues related to insulation in the secondary relay protection loop can lead to errors or malfunctions in the relay protection system, thereby jeopardizing the overall stability of the power grid. With this in mind, this paper focuses on the insulation testing technology for the secondary loop. It introduces an insulation testing method designed specifically for the secondary loop to ensure its safe and stable operation, which is crucial for maintaining the reliability of the entire power system.
