Hazardous waste landfill is the final way to dispose of hazardous waste and its environmental risk is different from that of domestic waste landfill. Its dangerous characteristics will not decrease with time, but will exist for a long. The environmental risks of hazardous waste landfills are concentrated in the probability risk of leakage of the impermeable layer. Therefore, it is of great significance to calculate the environmental risk of the leakage source intensity of typical hazardous waste landfills. In order to adapt to the personalized customer needs caused by social and economic development and to pursue new competitive advantages, the production mode of manufacturing enterprises is gradually changing to a small-batch and multi-variety customized mode. The complex and dynamic production environment caused by determinism puts forward higher requirements for the operation control accuracy of large-scale multiunit production systems. To support the efficient and coordinated operation of each link is a key challenge for process control of large-scale multiunit production logistics systems. This article proposes to accelerate the integration of information technology and manufacturing technology to promote the application of intelligent manufacturing process, intelligent logistics management, and other technologies in the production process. The research object is to study the multiunit linkage optimization problem under the framework of digital twin technology, through the real-time collaborative decision-making and feedback execution of the production, transportation, and warehousing multi-decision links to solve the “production-transportation-storage” decision-making in a dynamic environment. We analyzed the problems brought about by the dynamic interference of the execution process on the “production-transportation-storage” linkage operation process of the industrial park and analyzed the challenges of realizing the online linkage decision-making of “production-transportation-storage.” Based on the classic digital twin framework, a cross-unit digital twin linkage decision information architecture is proposed. Compared with the conclusions of the original environmental impact assessment report of the project, the post-environmental impact assessment results basically conform to the relevant descriptions, and a few nonconformities have been resolved during the project operation. The environmental protection measures of this project are relatively complete, which can meet various environmental protection requirements and enterprise development needs during the operation period of the project. For some environmental risks found in the process of project operation, evasion measures are proposed to reduce the possibility of environmental pollution accidents, and emergency measures can be taken in time when accidents occur. The practice of post-assessment of the environmental impact of this hazardous waste landfill is generally successful, and it has certain reference significance for the subsequent post-assessment of the environmental impact of other hazardous waste landfills.
With the increasing pressure of social life, people generally have different degrees of psychological problems, which brings serious troubles to people’s life and work. As one of the main forms of art, animation is a good medicine for breaking fantasy and returning to reality. Animation is one of the ways of art therapy, and animation art design is the soul of animation therapy. However, the art design of traditional animation cannot bring a strong sense of resonance and cannot arouse people’s inner emotions. Virtual reality can bring users an immersive experience, so it can really immerse the audience and release psychological pressure. The article firstly reoptimizes animation modeling technology and then combines it with art design, comprehensively uses art design and interactive technology to generate virtual space, and finally puts forward the concept of animation art design based on virtual reality technology. It aims to construct virtual animation from animation art design to help patients relieve psychological barriers. After repeated comparison experiments, it can be found that in the process of watching interactive animations on the virtual reality platform, if the overall style of the animation is more comfortable and warm, the user’s psychological perception will reach 78%, and the emotional fluctuation range will be less than 10%. When the animation style is relatively dark and depressing, the user’s psychological perception is only 45%, and the audience is very likely to think of a bad life experience, and the possibility of causing psychological disorders is 69.1%. This shows that the warm and comfortable animation art design can smooth people’s emotional fluctuations and relieve psychological obstacles.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
