As a key technology for intelligent vehicles, autonomous valet parking is becoming increasingly popular in the area of research. Autonomous valet parking technology is available for safe and quick parking operations without a driver, and improving the driving convenience while greatly reducing the probability of parking accidents. A path planning method of autonomous valet parking in parking lots mixed traffic scenarios is proposed in this paper to resolve the following issues presented in the existing autonomous valet parking systems, that is, low efficiency of global path planning and low success rates of local obstacle avoidance. First, the parking lot traffic scenario model is established and analyzed. Secondly, a global path planning method based on Floyd algorithm is proposed and optimized. Then, the obstacle avoidance path is decoupled laterally and longitudinally based on the fifth-order polynomial in the Frenet coordinate system, and the optimal local path is screened out through the coupling loss function and defined constraints. Finally, a simulation scenario was built to verify the path planning method studied in this article. The results show that the autonomous valet parking path planning method studied in this paper can achieve good results and has strong robustness.

Warehousing, as the basic link between the supply and demand side, plays a very important role in logistics activities. It is pointed out in the Logistics Warehouse Industry Blue Book that in the future, investment in high-end warehousing facilities will continue increasing. Capital will continue being gathered in core areas and backbone nodes, and the transformation to an informatized, comprehensive, professional and automated smart warehousing will be accelerated by modern logistics warehousing. A set of modular miniload has been developed in this project, breaking through the traditional mode of the existing logistics equipment integration market. Modular, lightweight, low-cost, low-energy-consumption, easy-operating and maintaining, adaptable, intelligent as well as three-dimensional box automation warehouse logistics automation solutions are developed.

In view of the low efficiency of tunnel fire rescue, the difficulty of operation and the difficulty of determining the kindling point, a real-time monitoring system based on multi-sensor devices for smoke, temperature and video is designed based on the restricted fire development law in tunnel and the smoke movement process. Then the target tunnel is modeled and the fire monitoring conditions under different combustion conditions inside the tunnel are simulated using FDS software. Finally, the situation evaluation of tunnel fire is given by analyzing the temperature, toxic gas concentration and the distribution and development law of fire smoke inside the tunnel monitoring system.

Formal methods are used to improve the credibility and correctness of scenarios in Chinese Train Control Systems (CTCS). At present, there are few formal studies on the high-speed Automatic Train Operation system that developed from CTCS-3 level high-speed railway technology. In this paper, we adopt a new formal method, Alvis, which combines the advantages of high-level programming language and graphical modeling and select the interzone TSRS handover scene in high-speed railway ATO system as the research object. The messaging behaviors of the scene are analyzed using UML sequence diagrams, and an Alvis model of the system is built, which is converted into an smv model supporting the formal validation of the model checking tool nuXmv. The real-time performance of the extracted messaging was verified on demand, inconsistency between technical specifications and actual operational scenarios was identified and solution was provided. The results of this method can provide some reference for the technical promotion of ATO train control system in China.

With the increasing diversification and individualization of consumer demand, the consumption environment of agricultural products has also changed significantly. While many agricultural products supply chains are fully engaged in traditional retail channels, they are also generally opening online sales channels, thus forming a dual-channel circulation mode of farm products in which conventional and online retail channels coexist. Due to the high overlap between the two sides in selling products and target users, the potential conflicts in the dual-channel supply chain of agricultural products have become increasingly prominent. Under the guidance of evolutionary game theory, this paper analyzes the collaborative evolution law of supply chain enterprises under the penalty mechanism. By simulating the game process of cooperation between the two parties, it is found that setting a reasonable punishment mechanism can reduce opportunistic behavior. It can not only enrich and expand the research horizon and depth of the dual-channel supply chain of agricultural products but also have important theoretical and practical significance for promoting the cooperation of the dual-channel supply chain of agricultural products, realizing the resource sharing and complementation of the two channels, and improving the benefits of the whole supply chain.

The effects of different types and amounts of high viscosity modifiers on bitumen properties are investigated by conventional bitumen property tests and DSR and BBR rheological property tests. And the optimal content of modifier and the viscosity control mechanism of different kinds of modifiers are determined. On this basis, WTR compound high viscosity modified bitumen (RPRA for short) was prepared. The results showed that the rheological properties of RPRA high-viscosity bitumen were optimal when the compound modified bitumen was prepared with 20% waste rubber powder, 5% recycled plastic and 3% polyethylene wax.

Puzzle-Based Storage system (PBS) is an innovative type of high-density Automated Storage/Retrieval System (AS/RS), which is made up of massive adjacent square cells (moveable shelves) arranged in a rectangular grid to allow stored unit-loads to be accessible individually. Previous research mainly focused on reducing retrieval time, designing retrieval algorithms, and improving retrieval performance. Since the lack of research on the impact of the number of unit-load moves from the perspective of escort distribution, this study proposes three escort distribution strategies when retrieving the unit-load in the PBS. Furthermore, the research analyzes the relationship between the number of escorts and the density and conducts simulation experiments in PBS systems of different scales as well. Simulation results show that the increase in the number of escorts would no longer affect the number of movements when the PBS density reached 40%-50%. In summary, the retrieve unit-loads require the minimum number of movements in diagonal distribution, while random distribution is superior to the arrangements in the first line.

With the continuous construction of expressways in China, the timely process of traffic incidents has been increasingly valued to avoid heavy traffic and secondary incidents. To timely eliminate the terrible influence of incidents, the indirect incident detection method is designed and presented based on the actual data of the segment from the Lingdian interchange to the Tangwang interchange hub of the Jinan-Guangzhou expressway in this paper. Firstly, the existing data from diverse detection systems are collected and integrated into a unified format. Then, an actual-data-based simulation experiment is achieved to offer the required information to the indirect incident detection method through VISSIM. On this basis, a series of parameters are constructed to identify the mutation of traffic operation from multi-dimension. Finally, the indirect incident detection method is trained to recognize the mutation of traffic and classify the normal scene and incident scene with LightGBM. Compared to KNN, RF, and SVM, the LightGBM has an excellent performance on incident identification, with a 98.6% accuracy, a 100% precision, an 88.9% recall, and a 94.1% F1 score.
