[Abstract]:Hazardous chemicals refer to articles with special physical, chemical or biological characteristics that are very easy to cause safety accidents such as combustion, explosion and poisoning in production, storage and transportation. With the development of industrialization, the production and transportation of dangerous chemicals are increasing year by year, and the accidents of dangerous chemicals flow frequently. The main reason is from the logistics activities of dangerous chemicals. With the development of the Internet of things, RFID and WSN technology are developing continuously with the development of the Internet of things. With the development of the Internet of things and the development of the technology of RFID and WSN, the establishment of the information system with the ability of real-time monitoring, management and early warning for the whole process of hazardous chemicals logistics is a solution to various problems in the supervision and operation of the logistics activities of dangerous chemicals. The essence of Logistics Intelligent Monitoring and Application Research Based on RFID and WSN is the essence of the research on the logistics information methods and theoretical problems of dangerous chemicals. The main contents include the introduction and construction of intelligent decision-making model blocks to establish the framework for the logistics information system of dangerous chemicals on the basis of fully understanding the characteristics of RFID and WSN. Using the scientific method to optimize the logistics process of dangerous chemicals; under this framework, we excavate two core problems of transportation and storage in the logistics decision-making problem of dangerous chemicals and reshape the solutions and methods of decision-making problems. Therefore, based on the research of intelligent monitoring and application of the logistics of dangerous chemicals based on RFID and WSN, the scientific method of logistics information technology for dangerous chemicals is established. And the theory has the guiding significance. The research results are as follows: 1. the characteristics of RFID and WSN technology, the application status and the characteristics of the logistics application of dangerous chemicals are analyzed, and the influencing factors of the selection of RFID and WSN are analyzed. On the basis of the analysis of the logistics characteristics of dangerous chemicals, the intelligent monitoring scheme based on RFID and WSN is constructed and the framework is constructed in this framework. The information management requirements for the intelligent monitoring of dangerous chemicals are analyzed. Based on the classification of dangerous chemicals, the objects of information management for the intelligent monitoring of dangerous chemicals are defined, and the information collection objects of 8 types of dangerous chemicals under different storage and transportation are listed, and the logistics intelligent supervision of dangerous chemicals based on RFID and WSN is carried out according to the object-oriented analysis method. The system carries out the requirement analysis, analyzes the basic use case of the system, aims at the performance requirements of the system design, and other requirements, and constructs the functional framework and module of the software system, constructs the logical framework of the hardware system, introduces the structure and internal logic relation of the system, and introduces the intelligent decision function module, gives the overall structure and the prominent model. The key role and composition of the type library and analysis of the core problem of the logistics intelligent decision of dangerous chemicals.2. research and analyze the status and characteristics of the logistics storage and transportation process of dangerous chemicals. In view of the characteristics of the logistics process of dangerous chemicals, the workflow modeling method of workflow empowerment with the time security performance comprehensive evaluation idea is put forward, and the method is used in this method. Based on the formalized modeling and analysis of the process of dangerous chemicals, in view of the shortage of the existing logistics process of dangerous chemicals, the paper gives some suggestions and measures to optimize the logistics process of dangerous chemicals..3. studies the storage and distribution method of dangerous chemicals based on the rolling time optimization strategy, considering the uncertainty of the transportation process and arrival time, and is dangerous to the storage capacity of the warehouse. Under the constraints of warehouse storage capacity, warehouse environment, warehouse and transportation conditions, the storage and distribution model of dangerous chemicals based on the rolling time optimization strategy is constructed to solve the.4. research on the problem of warehouse determination and the distribution of storage reserves in the storage and distribution of dangerous chemicals. Considering the time window and the path set, the logistics transportation decision-making model is considered as the goal of minimum social risk and minimum transportation cost. It considers the constraints of road transport capacity, node storage capacity, transportation path and time window. Based on the characteristics of the model, the ant swarm optimization algorithm is used to solve the model. Finally, the model is used to model the model. And the algorithm is verified. Because the logistics information problem of dangerous chemicals is subject to the development of information technology, as well as the constraints of the change of the focus on the logistics management system of dangerous chemicals, the choice of information technology and the way of system formation and the decision-making problems involved will be constantly changed. The relationship and mechanism of the framework of the logistics intelligent monitoring system based on RFID and WSN, the multi-dimensional performance analysis function of the modeling method of the workflow empowerment performance colored Petri net, the versatility of its modeling and analysis, the emergency support decision involved in the intelligent logistics operation of the dangerous chemicals, the selection decision of the service provider, the enterprise strategy and the strategy Business decisions need to be further studied.
