| Summary: | To meet the monitoring demand of larger range, stronger stability and higher safety performance in nuclear power plant and on the basis of the current use of wireless sensor technology in nuclear power plant and the current research of domestic and foreign scientific research institutions, this paper puts forward a three- dimensional monitoring method and builds model of system for radiation field of nuclear power plant based on wireless sensor technology. A decision-making model for hazardous chemicals logistics considering time window and route set is researched. Targeting smallest social risk and transport expense, transport capacity of road, storage capability of nodes, transport route and time window are overall considered. Considering features of the model, ant colony algorithm with elite strategy is designed to solve the model. At last, living example is used to verify the model and algorithm. It proves that the application based on RFID and WSN wireless sensor technology achieves smart monitoring on the logistics of hazardous chemicals. This has guiding significance for making scientific method and theory of hazardous chemicals logistics informatization.
